Background
Coronavirus Disease 2019 (COVID-19) is an emerging and rapidly evolving disease, with no recommended effective anti-coronavirus drug treatment. Traditional Chinese Patent Medicines (CPMs) have, however, been widely used to treat COVID-19 in China, and a number of clinical practice results have shown them to have a significant role in its treatment. Consequently, numerous guidelines and expert consensus have recommended the use of CPMs to treat COVID-19.
Aim of the Study
The objectives of this review are to provide up-to-date information on the pharmacology and clinical research on CPMs in the treatment of COVID-19, discuss the research findings, and to better guide clinical application and scientific research on CPMs in the treatment of COVID-19.
Methods
The frequencies of CPM recommendations by guidelines and expert consensus for treatment of COVID-19 in China were ranked. This report identifies the top 10 CPMs, which include Huoxiang Zhengqi capsule (HXZQC), Lianhua Qingwen capsule (LHQWC), Jinhua Qinggan granule (JHQGG), Shufeng Jiedu capsule (SFJDC), Tanreqing injection (TRQI), Xiyanping injection (XYPI), Xuebijing injection (XBJI), Shenfu injection (SFI), Shengmai injection (SMI), and Angong Niuhuang pill (AGNHP). Relevant studies from 2000 to 2020 on these top 10 CPMs, covering usage, dosage, mechanism, curative effect, and precautions, were collected from pharmacopoeia, reports, and theses via library and digital databases (including PubMed, CNKI, Google Scholar, Web of Science, and Elsevier).
Results
The properties of the top 10 CPMs included antiviral, antibacterial, anti-inflammatory, antipyretic and analgesic, anti-acute lung injury, anti-shock, immune regulation, and enhancement of pulmonary function. In addition, clinical research results and Chinese treatment data showed that the CPMs had good therapeutic efficacy in the treatment of COVID-19, and adverse reactions were minimal.
Conclusions
Knowledge of the characteristics of the top 10 CPMs and precautions that should be taken may help clinicians to rationally improve therapeutic efficacy, and promote the role of Chinese Medicine in the control of the COVID-19 global epidemic.

Introduction
COVID-19 is an emerging and rapidly evolving epidemic. The cumulative number of confirmed cases globally reached 1,040,772 on April 4, 2020, comprising 149,790 (14.39%) cured cases, and 55,698 (5.35%) deaths. The causative organism has been designated as the 2019 novel coronavirus (2019-nCoV). On January 30, 2020, the epidemic was declared a public health emergency of international concern by the World Health Organization (WHO) (Fisher and Heymann, 2020). On February 11, 2020, the WHO Director-General, Tedros Adhanom Ghebreyesus, announced that the disease caused by this new coronavirus was “COVID-19,” which is an acronym for “coronavirus disease 2019.” The virus seems to be highly contagious and had quickly spread to 119 countries and regions by March 12, 2020. The clinical spectrum of COVID-19 varies from asymptomatic or paucisymptomatic forms to clinical symptoms characterized by respiratory failure that necessitates mechanical ventilation and support in an intensive care unit (ICU), to multiorgan and systemic manifestations in terms of sepsis, septic shock, and multiple organ dysfunction syndromes (MODS) (Wu and McGoogan, 2020). Currently, there is no effective anti-coronaviral drug that is recommended for treatment of COVID-19, and no vaccine is available. There is no evidence supporting the efficacy of broad-spectrum antibiotics, gamma globulin, interferon, or corticosteroid therapy for COVID-19. Treatment is symptomatic, and oxygen therapy represents the major intervention for patients with severe infection. Mechanical ventilation may be necessary in cases of respiratory failure refractory to oxygen therapy (Huang et al., 2020; Zhang et al., 2020).
Traditional Chinese Medicine (TCM) has a long history and has played an important role in the prevention and treatment of serious epidemic diseases. During the development of the COVID-19 epidemic, more than 3,100 TCM medical staff were deployed to Hubei province, and TCM was included in the guidelines for the diagnosis and treatment of COVID-19. Currently, the total number of confirmed cases treated by TCM has reached 60,107 (Gao, 2020). The decoctions, CPMs, acupuncture, and other TCM treatments have been comprehensively used for treatment, mainly based on syndrome differentiation. Specific CPMs have been widely employed to treat COVID-19 with remarkable therapeutic effects (National Health Commission of the People’s Republic of China and National Administration of Traditional Chinese Medicine, 2020).
CPMs are approved by the National Drug Regulatory Authority of China and processed according to prescribed methods using Chinese herbal medicines as raw materials, guided by the theory of TCM. They are available in different dosage forms, such as pill, tablet, capsule, granule, or injection. The use of CPMs is guided by syndrome differentiation and overall analysis of signs and symptoms. Provinces of China have prepared therapeutic schedules for the treatment of COVID-19 based on actual conditions (see Table 1 ). Many guidelines and expert consensus in China have recommended using CPMs to treat COVID-19. In this article, we identify the top 10 recommended CPMs to treat COVID-19 ( Figure 1 ). The list of CPMs includes Huoxiang Zhengqi capsule (HXZQC), Lianhua Qingwen capsule (LHQWC), Jinhua Qinggan granule (JHQGG), Shufeng Jiedu capsule (SFJDC), Tanreqing injection (TRQI), Xiyanping injection (XYPI), Xuebijing injection (XBJI), Shenfu injection (SFI), Shengmai injection (SMI), and Angong Niuhuang pill (AGNHP). Information on the drugs include the recommended guidelines, drug ingredients, indications, pharmacological research, clinical research, usage and dosage, adverse reactions, and precautions.

Acute URI + fever Improves respiratory symptoms (Wang and Qiu, 2018)
Anti-inflammation Reduces the WBC count, and reduces the serum transcription factor NF-κB, chemokine MCP-1, inflammatory mediator BK and COX-2 level (Ma et al., 2018). CAP Shortens recover time of multiple symptoms and signs such as fever, reduces levels of PCT, CRP and WBC and other indicators (Wang, 2016).
Immune-regulation Reduces levels of B lymphocytes, CD8+ proportion, IL-1α, IL-1β, IL-2, IgM, IgG, etc., reduces quality of thymus, spleen and lung of pneumonia mice, and increase CD4+/CD8+ and NK cell proportion (Ma et al., 2019). AECOPD Reduces levels of IL-8, TNF-α, CRP and PCT (Yu H. X. et al., 2020) and increases arterial blood gas PaO2 (Wang, 2015).
Anti-acute lung injury Inhibition of the MAPK/NF-κB signaling pathway, and down-regulation of NF-κB mRNA expression (Tao et al., 2014). The action might be closely related with ERK signaling pathway (Li et al., 2017). Bacterial acute bronchitis and Pneumonia Shortens recovery time of body temperature, duration of cough and the course of treatment, and increases oxygen index (Wang et al., 2014).
TRQI Anti-virus Inhibition of intracellular proliferation and enhancement of body immunity of mice infected with influenza virus (Zheng and Gu, 2009).

Acute lung injury Improves respiratory rate, oxygen index, and lowers the ICAM-1, ET-1 and NO level (Ma et al., 2019).
Respiratory failure Improves serum prealbumin, oxygen index, shortens the duration of mechanical ventilation (Li, 2013)
SMI Improve pulmonary function Raises NO level, dropping oxygen free radical levels and decreases lipid peroxidation (Lin et al., 2007). Lowers expression of NF-κB and activity of iNOS in lung tissues (Liu et al., 2009). COPD Improves pulmonary function index, blood gas index, IgG index and disappearance time of lung rale (Huang et al., 2019).
Anti-inflammation Inhibits expression of ICAM-1 and VCAM-1 (Liu et al., 2015). Inhibits generation of inflammatory cytokines of ischemia-reperfusion rats, lowers expression level of TNF-α, IL-6, IL-8, etc. (Wang et al., 2015)
Immune-regulation Inhibits monocyte MCP-1 (Liu et al., 2015). Increases the content of serum immunoglobulin IgG and the number of T cells, enhances the phagocytic function of macrophages (Du et al., 2001). Prevent inflammatory response Improves microcirculation, protect the organ functions, and prevents further occurrence and development of systemic inflammatory response syndrome (Guo et al., 2004).
Improve pulmonary function Raises NO level, dropping oxygen free radical levels and decreases lipid peroxidation (Lin et al., 2007). Lowers expression of NF-κB and activity of iNOS in lung tissues (Liu et al., 2009).
AGNHP Anti-inflammation Inhibits release of superoxide radical; reverses changes in cortical monoamine neurotransmitters (Zhang F. et al., 2010; Zhu and Sun, 2014). Lowers serum LPS level and lung myeloperoxidase (MPO) content (Zhang et al., 2009). Lowers total LDH activity, and changes percentage of isomerase (Tang et al., 2005).

Antipyretic and analgesic – ACI intracerebral hemorrhage Neuroprotective effect (Han et al., 2019). Research by Zhonghua Liu et al. (Liu, 2009) revealed that HXZQC inhibited the lung index of mice infected with avian influenza virus (AIV) H5N1, reduced the development of lung disease, and enhanced the antiviral capacity of mice infected with AIV. The death rate of the infected mice was reduced through regulation of the gastrointestinal tract and strengthening of the stomach Qi. Hongkun Zhang (Zhang, 2013) found that HXZQC inhibited growth of Vibrio parahaemolyticus, Candida albicans, Staphylococcus aureus, and Streptococcus pneumoniae. Research by Wang et al. (2012) found that HXZQC inhibited lipopolysaccharide (LPS)-stimulated expression of proinflammatory cytokines by macrophages and inhibited epithelial barrier disorder induced by interferon-γ (IFN-γ), regulating immunity and improving gastroenteric function. Research by Chunyuan Li et al. (Li et al., 2017) showed that HXZQC significantly improved the thymus coefficient, spleen coefficient and immunoglobulin G (IgG) levels of mice with dampness obstructing spleen-stomach, and enhanced the immune function of the mice. Studies by Yinghui He et al. (He et al., 2006) and Shaobo Zong et al. (Zong et al., 2015) discovered that HXZQC had therapeutic effects in mice with Bacillus dysenteriae and Salmonella typhimurium-induced diarrhea (BSD mice), mice with bacterial enteritis, and model rats with diarrhea-predominant irritable bowel syndrome (IBS). Clinical symptoms were significantly improved, which might be due to effects on the balance of CD4+ and CD8+ T lymphocytes, and reduction of interleukin-2 (IL-2), interleukin-10 (IL-10), interleukin-1β (IL-1β), and tumor necrosis factor alpha (TNF-α) levels. The results suggested that HXZQC, via immune-regulation and anti-inflammatory activity, could have therapeutic effects against many gastrointestinal disorders. Research by Hefei Huang et al. (Huang et al., 2016) showed that HXZQC extracts had a positive regulatory effect on intestinal dysfunction, and had therapeutic efficacy in model rats with diarrhea-predominant IBS. Efficacy was mediated by improving serum NO levels and reducing the concentrations of 5-hydroxytryptamine (5-HT), plasma motilin, and colonic somatostatin.
Clinical Research on HXZQC
Modern clinical studies have shown that HXZQC has therapeutic effects against viral diseases, such as gastrointestinal-type cold, influenza, upper respiratory infection (URI), and viral enteritis (see Table 3 ). The Diagnosis and Treatment Scheme of Severe Acute Respiratory Syndrome (SARS) (Version 2004) (Chinese Medical Association and China Association of Chinese Medicine, 2004) recommended that HXZQC could be used for advanced stage pulmonary closure.
Research by Shuping Ma et al. showed that, compared with the control group (Ribavirin, interferon), HXZQC + Western medicines (Ribavirin, interferon) had a significant effect on antidiarrheal time and shortened the total time course in the treatment of children with rotavirus enteritis (p < 0.05) (Ma and Wang, 2012). Xiaoping Han et al. (Han, 2016) randomized 78 influenza patients into control and observation groups. Patients in the control group were given oral oseltamivir phosphate, while patients in the observation group received HXZQC in addition to oseltamivir phosphate. Compared with those in the control group, patients in the observation group had faster relief of fever symptoms, muscle aches, and fatigue (p < 0.05). The total response rate in the observation group was 97.44%, which was higher than the 82.05% of the control group (p < 0.05). The results showed that HXZQC enhanced the efficacy of oseltamivir phosphate in the treatment of influenza. Xingzhou Wu (Wu, 2010) randomized 90 cold dampness patients into two groups: the treatment group received HXZQP, while the control group received Ribavirin injection + Compound paracetamol and amantadine hydrochloride capsules. The total response rate in the treatment group was 88.9% compared to 77.1% in the control group (p < 0.05). Patients in the treatment group exhibited greater improvements in aversion to cold, fever, nasal congestion, running nose, spontaneous sweating, headache, cough and spitting, fatigue and weakness, body ache, and other cold symptoms compared to the control group. Hongjie Zhao et al. studied the efficacy and safety of HXZQC in the treatment of gastrointestinal-type cold by systematic evaluation. A total of 680 patients in eight randomized controlled trials (RCTs) were included in the research, and the results showed that the group receiving HXZQC had a significantly better clinical response than the group using Western medicines alone. The effects of HXZQC were superior to Western medicines in improving single symptoms (such as aversion to cold, fever, bowel sound and diarrhea) (Zhao et al., 2017). Dandan Yu et al. conducted a meta-analysis of 44 studies, including a total of 4,153 patients with acute gastroenteritis. The results showed that treatment with HXZQP + conventional therapy or norfloxacin tablets was superior to a single Western medicine in terms of total response rate and improvement of clinical symptoms (Yu et al., 2019).
Usage and Dosage of HXZQC
Oral administration, four capsules, twice a day.
Adverse Reactions of HXZQC
Potential drug eruption, purpura, shock, asthma, intestinal obstruction, upper gastrointestinal hemorrhage, hypoglycemia of childhood, infantile convulsions.
HXZQC Precautions
1) Nourishing traditional Chinese medicines should not be taken during the period of medication. 2) It is advisable that patients are on a light diet during the period of medication.
Relevant Information on the Clinical Application of LHQWC
Recommended Therapeutic Regimens
LHQWC has been recommended in 19 therapeutic regimens for treatment of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of LHQWC
Forsythia suspensa (Thunb.) Vahl (Lianqiao), Lonicera japonica Thunb. (Jinyinhua), Ephedra equisetina Bunge (Zhimahuang), Prunus armeniaca L. (Chaoxingren), Gypsum fibrosum (Shigao), Isatis tinctoria L. (Banlangen), Dryopteris crassirhizoma Nakai (Guanzhong), Houttuynia cordata Thunb. (Yuxingcao), Pogostemon cablin (Blanco) Benth. (Guanghuoxiang), Rheum palmatum L. (Dahuang), Rhodiola rosea L. (Hongjingtian), Mentholum (Bohenao), and Glycyrrhiza uralensis Fisch. ex DC. (Gancao). Basic information on LHQWC is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With LHQWC
LHQWC is used during the clinical observation period of COVID-19, and wind-heat invading lung in early stage of the disease (mild case). The indicative symptoms are fever, mild aversion to cold, cough, weakness, headache and body pain, sore throat, and constipation.
Progress of Pharmacological Research on LHQWC
Modern pharmacological studies have shown that LHQWC has antiviral, immune-regulatory, anti-inflammatory, and antioxidant properties, efficacy against lung injury, and other effects (see Table 3 ).
LHQWC significantly inhibited SARS-CoV-2 replication in Vero E6 cells and markedly reduced the production of pro-inflammatory cytokines (TNF-α, IL-6, CCL-2/MCP-1, and CXCL-10/IP-10) at the mRNA level. Furthermore, LHQWC treatment resulted in abnormal virion particle morphology in cells. LHQWC significantly inhibits SARS-CoV-2 replication, affects virus morphology and exerts anti-inflammatory activity in vitro (Li R. F. et al., 2020).
In vitro experiments have shown significant antiviral activity against SARS-CoV, AIV H7N9, dual H1N1/H3N2, together with inhibition of Middle East Respiratory Syndrome (MERS)-CoV activity to a certain degree (Yao et al., 2020). Yuewen Ding et al. used MTT and plaque reduction assays to show that LHQWC inhibited proliferation of multiple strains of influenza virus, and reduced virus titer and levels of inflammatory cytokines in the lungs of infected mice. The results indicated that LHQWC acted as a broad-spectrum antiviral and, in particular, regulated the immune response to viral infection (Ding et al., 2017). Qi Li et al. discovered that LHQWC not only reversed LPS-stimulated expression of macrophage chemotactic factor-1 (MCP-1) by macrophages, but also significantly improved pulmonary edema in a mouse model of acute lung injury. Inhibition of expression and secretion of MCP-1 in lung tissues of model mice was accompanied by reduced infiltration of mononuclear macrophages and reduction of inflammatory injury (Li et al., 2019). Fen Ping et al. studied the effects of LHQWC on rats with oxidative lung injury caused by fine particulate matters (PM 2.5). The results showed that LHQWC significantly reduced lactate dehydrogenase (LDH) and malondialdehyde (MDA) serum levels in rats with lung injury, increased levels of glutathione peroxidase (GSH-Px), reduced pathological damage of lung tissues, and inhibited exudation of inflammatory cells into the alveolar cavity. Together, the data indicated that LHQWC protected against oxidative stress injury in the lungs of rats (Ping et al., 2016). Wenwen Cui et al. studied the impact of LHQWC in a mouse model of acute lung injury caused by intratracheal infusion of LPS. LHQWC alleviated the inflammatory response in lung tissues by downregulating the IKK/IκB/nuclear factor (NF)-κB signaling pathway, thus, protecting mice from acute lung injury (Cui et al., 2016). Siwen Tang et al. studied the effects of LHQWC intervention on pathological lung tissue injury in mice and expression of inflammatory cytokines caused by exposure to automobile exhaust. The results showed that LHQWC reduced protein and mRNA expression of inflammatory cytokines in lung tissue by reducing blood levels of inflammatory cytokines, thus, protecting against lung tissue injury caused by automobile exhaust (Tang et al., 2015).
Clinical Research on LHQWC
Modern clinical studies have shown that LHQWC has therapeutic effects against viral diseases, such as COVID-19, SARS, MERS, influenza, and human infection with H7N9 avian influenza. It can also be used to treat URI, chronic obstructive pulmonary disease (COPD) and other conditions (see Table 3 ). LHQWC has been recommended in diagnosis and treatment schemes such as China’s SARS Diagnosis and Treatment Scheme (Version 2004) (Chinese Medical Association and China Association of Chinese Medicine, 2004), MERS Diagnosis and Treatment Scheme (Version 2015) (National Health and Family Planning Commission of People’s Republic of China, 2015), China’s Influenza Diagnosis and Treatment Scheme (Version 2019) (National Health Commission of the People's Republic of China and National Administration of Traditional Chinese Medicine, 2019), and Diagnosis and Treatment Scheme for Human Infection with H7N9 Avian Influenza (Version 1, 2017) (National Health and Family Planning Commission of People's Republic of China, 2017).
Ke Hu et al. conducted a prospective multicenter open-label randomized controlled trial on LHQWC capsule in confirmed cases of COVID-19. Patients (284) were randomized to receive usual treatment alone or in combination with LHQWC capsules (four capsules, thrice daily) for 14 days. The primary endpoint was the rate of symptom (fever, fatigue, coughing) recovery. The recovery rate was significantly higher in the combined treatment group compared with the control group (91.5% vs. 82.4%, p = 0.022). The median time to symptom recovery was markedly shorter in the combined treatment group (median: 7 vs. 10 days, p < 0.001). Time to recovery of fever (2 vs. 3 days), fatigue (3 vs. 6 days) and coughing (7 vs. 10 days) was also significantly shorter in the combined treatment group (all p < 0.001). The rate of improvement in chest computed tomographic manifestations (83.8% vs. 64.1%, p < 0.001) and clinical cure (78.9% vs. 66.2%, p = 0.017) were also higher in the combined treatment group. However, the two groups did not differ in the rate of conversion to severe cases or viral assay findings (p > 0.05). No serious adverse events were reported (Hu et al., 2020).
Ruibing Lyu et al. conducted clinical research on 63 patients receiving conventional therapy in combination with LHQWC (treatment group) and 38 patients receiving only conventional therapy (control group). Clinical data were collected 10 days after the treatment. A comparison between the two groups was performed in terms of disappearance rates of cardinal symptoms (fever, cough, and weakness), duration of fever and disappearance rates of other individual symptoms and signs. The disappearance rates of fever, cough, and weakness in the treatment group were 86.7%, 55.6%, and 82.5%, respectively, which were higher than those in the control group (67.7%, 30.6%, and 58.6%; p < 0.05). The median duration of fever was 6 days in patients in the treatment group and 7 days in the control group. There was no statistically significant difference between the groups (p = 0.171). The disappearance rates of short breath and moist crackles (68.2% and 56.0%) were higher than those in the control group (20.0% and 20.0%, p < 0.05). There were four cases of aggravation in the treatment group (6.4%) and six cases in the control group (15.8%), with no statistically significant difference (p > 0.05). There were no obvious adverse reactions in the treatment group (Lyu et al., 2020).
Dezhong Cheng et al. conducted a multi-center retrospective analysis of the therapeutic effect of LHQWC in 51 COVID-19 patients. The control group was treated with simple nutritional support, symptomatic treatment, antiviral therapy and antimicrobial therapy. The treatment group was combined with LHQWC (6 g/bag) on the basis of the control group, one bag each time, 3 times a day. The clinical data of patients treated for 7 days were collected. The results showed that combined application of LHQWC significantly improved fever, weakness, cough, shortness of breath, chest distress, anorexia, and other clinical symptoms of COVID-19. Improvements of the main symptoms and reduced incidence of the severe form suggested that LHQWC could be effective in the treatment of patients with COVID-19 (Cheng et al., 2020).
Ping Yu et al. conducted a study on the therapeutic effect of LHQWC combined with Abidole in the treatment of mild COVID-19. A total of 295 patients were randomly divided into two groups. The control group (n = 148) was treated with Abidole (0.2 g per day) orally, and the observation group (n = 147) was treated with LHQWC (6 g, thrice daily) combined with Abidole. The results showed that the total effective rate of the observation group was significantly higher than that of the control group (80.95% vs 64.86%), and the rate of severe illness was significantly lower than that of the control group (14.29% vs 23.65%). After 7 days of treatment, the scores for the main TCM syndromes (fever, fatigue, cough, dry throat, chest tightness) and the levels of C-reactive protein (CRP) and procalcitonin (PCT) in the observation group were significantly lower than those in the control group (p < 0.05), while white blood cells (WBC) and lymphocyte (LYM) were significantly higher than those in the control group. The effective rate of chest computerized tomography (CT) in the observation group was 69.39%, which was higher than that in the control group (62.84%), but the difference was not statistically significant (p > 0.05). There were no serious drug-related adverse reactions in either group. The results show that LHQWC combined with Abidole can effectively relieve clinical symptoms in patients with mild COVID-19, regulate the expression of related inflammatory factors, improve the curative effect and reduce the rate of severe illness (Yu P. et al., 2020).
Lili Liu et al. conducted a retrospective analysis of the therapeutic effect of LHQWC in 32 COVID-19 patients. The patients were divided into two groups: Group A + L, in which 18 patients received Abidole (0.2 g, thrice daily) combined with LHQWC; and Group L, in which 14 patients received LHQWC alone. During treatment there was one critical case in each group. Abnormal liver function was observed in 14 cases (77.78%) in Group A + L and 8 cases (57.14%) in Group L. Antibiotic treatment was applied in 17 cases (94.44%) in Group A + L and 13 cases (92.86%) in Group L. Glucocorticoid use was reported in 10 cases (55.56%) in Group A + L and 9 cases (64.29%) in Group L. Compared with Group L, significantly faster recovery of temperature (t = −2.471, p = 0.019), recovery of respiratory symptoms (t = −2.918, p = 0.007), chest CT inflammation absorption (t = −2.937, p = 0.006), time until two consecutive negative virus nucleic acid tests (t = −2.930, p = 0.006), and shorter hospital stay (t = −2.785, p = 0.009) were observed in Group A + L. Abidor combined with LHQWC can be used to treat COVID-19, with good tolerance, to shorten the course of treatment (Liu et al., 2020).
Zhongping Duan et al. conducted a random, double-blind, and positive-drug parallel control clinical trial on the efficiency and safety of LHQWC against H1N1. It was found that LHQWC reduced disease severity and the duration of symptoms. The drug was also well tolerated, indicating that LHQWC might become an alternative therapeutic measure against H1N1 viral infection (Duan et al., 2011). Pan Zhao et al. found by meta-analysis that LHQWC improved cough, sore throat, body ache, and other symptoms of patients infected with H1N1 virus, reduced the duration of fever, and was more effective than oseltamivir (Zhao P. et al., 2014). Shiheng Wang et al. conducted a systematic review of the literature on efficacy and safety of LHQWC in treating viral flu. The results showed that LHQWC gave a better total response rate, symptom improvement rate and body temperature recovery rate than the control group in treating viral flu, but consideration of its safety was important (Wang et al., 2019). Li Tiehui et al. compared the clinical therapeutic effect of LHQWC and vitamin C Yinqiao Tablets in patients with URI, and found that LHQWC significantly improved nasal congestion, fever, headache, sore throat, weakness, aches in the limbs, intolerance of cold, and other clinical symptoms. LHQWC had high efficacy and safety, and was therefore worthy of promotion (Li, 2019). Dong Liang et al. conducted clinical research on 100 patients with COPD, and discovered that LHQWC improved conditions in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), especially those in the high risk subgroup. The mode of action might be related to its ability to reduce release of inflammatory mediators (Dong et al., 2014).
Usage and Dosage of LHQWC:
Oral administration, four capsules, 3 times a day.
Adverse Reactions of LHQWC
Possible nausea, vomiting, diarrhea, stomach discomfort, heartburn, poor appetite, and other gastrointestinal adverse reactions; there might be abnormal liver function, palpitations or rash, and other side effects occasionally.
LHQWC Precautions
1) Pregnant and lactating women should use with caution. 2) It contains ephedrae herba (Mahuang), so should be used with caution by athletes and patients with high blood pressure and heart disease. 3) Those with previous history of liver disease or with abnormal liver function should use with caution. 4) It contains rheum, so the dose should be reduced appropriate in subjects who experience increased stool frequency and shapeless stools after administration. 5) Nourishing traditional Chinese medicine should not be taken at the same time.
Relevant Information on the Clinical Application of JHQGG
Recommended Therapeutic Regimens
JHQGG has been recommended in 13 therapeutic regimens of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of JHQGG
Forsythia suspensa (Thunb.) Vahl (Lianqiao), Lonicera japonica Thunb. (Jinyinhua), Ephedra equisetina Bunge (Zhimahuang), Prunus armeniaca L. (Chaoxingren), Gypsum Fibrosum (Shigao), Scutellaria baicalensis Georgi (Huangqin), Fritillaria thunbergii Miq. (Zhebeimu), Anemarrhena asphodeloides Bunge (Zhimu), Arctium lappa L. (Niubangzi), Artemisia annua L. (Qinghao), Mentha canadensis L. (Bohe), and Glycyrrhiza uralensis Fisch. ex DC. (Gancao). Basic information on JHQGG is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With JHQGG
JHQGG is used to treat the syndrome of wind-heat invading lung during the clinical observation period of COVID-19 and the early stage of the disease (mild case). Indicative symptoms are fever, mild aversion to cold, weakness, cough, headache and body pain, and sore throat.
Progress of Pharmacological Research on JHQGG
Modern pharmacological studies have found that JHQGG has antiviral, immune-regulatory, and anti-inflammatory effects (see Table 3 ).
Jianping Qi et al. showed that JHQGG significantly decreased the average levels of C-reactive protein (CRP) and IFN-γ in serum of influenza patients. Patients exhibited decreased inflammatory response and improved immune function after treatment, which might be due to the antiviral activity of the main ingredients, such as Lonicerae japonicae flos, Scutellariae radix, Forsythiae fructus, and Artemisiae annuae herba (Qi et al., 2016).
Clinical Research on JHQGG
Modern clinical studies have shown that JHQGG has therapeutic efficacy against viral diseases (see Table 3 ). JHQGG has been recommended in China’s Influenza Diagnosis and Treatment Scheme (Version 2019).
COVID-19 outpatients (123) were randomly divided into a treatment group (JHQGG two bags per time, 3 times a day, combined with routine treatment for 5 days, n = 82) and a control group (only routine treatment, n = 41). The addition of JHQGG significantly alleviated fever, cough, fatigue, sputum and anxiety, and the hospitalization rate tended to be lower than in the control group (Duan et al., 2020). In treatment of H1N1, use of JHQGG alone or in combination with oseltamivir effectively shortened fever duration. The duration of fever in patients treated with oseltamivir in combination with JHQGG was significantly shorter (19%) than in those treated with oseltamivir alone, suggesting that JHQGG could serve as an alternative therapeutic measure against H1N1 (Wang C. et al., 2011). Jianping Qi observed 174 cases of influenza patients and found that JHQGG significantly reduced serum levels of cytokines and improved immune function (Qi et al., 2016). A double-blind, randomized and controlled study on JHQGG in treating influenza syndrome of wind-heat invading lung by Guoqin Li et al. showed that it was effective and safe (Li et al., 2013).
Usage and Dosage of JHQGG
Taken after dissolving in boiled water, one bag, 3 times a day.
Adverse Reactions of JHQGG
Potential for nausea, vomiting, diarrhea, stomach discomfort, heartburn, poor appetite and other gastrointestinal adverse reactions; there might be abnormal liver function, palpitations, or rash occasionally.
JHQGG Precautions
1) Those with deficiency-cold in spleen and stomach should use with caution. 2) It contains ephedrae herba (Mahuang), so should be used with caution by athletes and patients with high blood pressure and heart disease. 3) Those with previous history of liver disease or with abnormal liver function should use with caution. 4) Nourishing traditional Chinese medicine should not be taken at the same time.
Relevant Information on the Clinical Application of SFJDC
Recommended Therapeutic Regimens
SFJDC has been recommended in 15 therapeutic regimens of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of SFJDC
Reynoutria japonica Houtt. (Huzhang), Forsythia suspensa (Thunb.) Vahl (Lianqiao), Isatis tinctoria L. (Banlangen), Bupleurum chinense DC. (Chaihu), Patrinia scabiosifolia Link (Baijiangcao), Verbena officinalis L. (Mabiancao), Phragmites australis (Cav.) Trin. ex Steud. (Lugen), and Glycyrrhiza uralensis Fisch. ex DC. (Gancao). Basic information on SFJDC is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With SFJDC
SFJDC is used to treat external wind-heat syndrome during the clinical observation period of COVID-19 and the early stage of the disease (mild case). Indicative symptoms are fever, aversion to cold, cough with yellow phlegm, weakness, and sore throat.
Progress of Pharmacological Research on SFJDC
Modern pharmacological studies have found that SFJDC has antiviral, antibacterial, and anti-inflammatory properties and protects against lung injury (see Table 3 ).
Yanyan Bao et al. evaluated the broad-spectrum antiviral activity of SFJDC by cytopathic effect (CPE) inhibition. A total of eight viruses, including H1N1, herpes simplex (HSV), respiratory syncytial virus, adenovirus (ADV) and Coxsackie virus, were evaluated. SFJDC had significant in vitro broad-spectrum antiviral activity and the best inhibitory effect was against parainfluenza virus (PIV). Similar results were obtained from in vivo experiments (Qiu et al., 2014; Bao et al., 2019). Ying Liu et al. used H1N1 FM1 and PR8 strains to induce nasal drip infection in an immunocompromised mouse pneumonia model. Therapeutic and preventive effects of SFJDC were observed against H1N1 infection in vivo. The results showed that SFJDC influenced the immune function of the mice, improved pneumonia symptoms caused by influenza virus, reduced the lung index of mice infected with H1N1, significantly reduced mortality, and had good therapeutic efficacy (Liu et al., 2010). Research by Weiwei Lv et al. found that SFJDC had inhibitory activity against multiple viruses and bacteria. Its antiviral activity was inferior to that of Ribavirin, but its cytotoxicity was lower. Both antiviral activity and antibacterial action were superior to those of Qingkailing granules (QKLG) (Lv et al., 2013). Li Ma et al. used a mouse pneumonia model induced by Streptococcus pneumoniae to study the anti-inflammatory mechanism of SFJDC. They discovered that it reduced white blood cell (WBC) count, reduced serum levels of the transcription factor nuclear factor kappa B (NF-κB), MCP-1, inflammatory mediator BK and COX-2, thus, having a therapeutic effect in the model (Ma et al., 2018). Further studies found that SFJDC had a significant immune regulatory function, reducing levels of B lymphocytes, CD8+ cells, interleukin-1α (IL-1α), IL-1β, IL-2, IgM, and IgG to improve lung function in mice with pneumonia. SFJDC increased the CD4+/CD8+ ratio and number of natural killer (NK) cells, thus, having a therapeutic effect in the pneumonia model (Ma et al., 2019a; Ma et al., 2019b). Zhengang Tao et al. observed a protective function of SFJDC against endotoxin LPS-induced rat lung injury. Their results showed that SFJDC inhibited the LPS-induced inflammatory response, and reduced LPS-induced lung injury. Its mechanism of action might be inhibition of the MAPK (mitogen-activated protein kinase)/NF-κB signaling pathway and downregulation of NF-κB mRNA expression (Tao et al., 2014). Yanmei Li et al. used a Pseudomonas aeruginosa (PAK)-induced KM mouse acute lung injury model to explore the mode of action of SFJDC in treatment of acute lung injury. They found that SFJDC significantly alleviated lung injury in the model and its mode of action might be related to the ERK signaling pathway (Li et al., 2017).
Clinical Research on SFJDC
SFJDC comes from “Detoxification Powder,” and is mainly used to treat fever, parotitis, amygdalitis, plague, and other diseases. Recent studies have shown that SFJDC has good clinical efficacy against viral diseases (such as MERS, influenza, human infection with H7N9 avian influenza) and respiratory diseases (such as acute URI, AECOPD, pneumonia, etc.) (see Table 3 ). SFJDC has been recommended in diagnosis and treatment schemes such as MERS Diagnosis and Treatment Scheme (Version 2015), China’s Influenza Diagnosis and Treatment Scheme (Version 2019), and Diagnosis and Treatment Scheme for Human Infection with H7N9 Avian Influenza (Version 1, 2017).
Lei Wang et al. conducted a retrospective analysis of 87 patients with acute URI + fever, and found that patients treated with SFJDC had a significantly higher total response rate than those in the control group. SFJDC effectively improved respiratory symptoms in patients with acute URI + fever (Wang and Qiu, 2018). In the treatment of community acquired pneumonia (CAP), application of SFJDC shortened recovery time, reduced the duration of fever and reduced the levels of procalcitonin (PCT), CRP, WBC, and other indicators, effectively shortening the course of treatment (Wang, 2016). Hongxia Yu et al. evaluated the impact of SFJDC on inflammation-associated cytokines in patients with AECOPD. The results showed that SFJDC significantly reduced the levels of interleukin-8 (IL-8), TNF-α, CRP, and PCT, and had significant therapeutic efficacy against AECOPD (Yu H. X. et al., 2020). Tiling Wang et al. added SFJDC treatment to conventional treatment in 60 mild and moderate AECOPD patients and compared with 60 patients receiving conventional treatment as the control group. After 1 week, the treatment group had significantly higher arterial blood gas PaO2 than the control group, without any adverse reactions (Wang, 2015). Research showed that treatment of bacterial acute bronchitis and pneumonia with a combination of antibacterial drugs and SFJDC significantly shortened recovery of body temperature, duration of cough and the course of treatment compared with antibacterial drug alone. Chunlan Wang et al. observed that combined use of SFJDC and antibiotics significantly improved body temperature, blood sugar, ALT (glutamate transaminase), AST (aspartate aminotransferase) and other indicators compared with the control group, and patients had a higher oxygen index than the control group. The results suggested that SFJDC had a significant protective function against lung injury, and the mechanism might be related to inhibition of inflammatory response by SFJDC (Wang et al., 2014).
Usage and Dosage of SFJDC
Oral administration, four capsules, 3 times a day.
Adverse Reactions of SFJDC
Occasional nausea.
SFJDC Precautions
(1) Use is forbidden in those with allergic constitution or who are allergic to the drug. (2) Use is forbidden in those with deficiency-cold in spleen and stomach.
Relevant Information on the Clinical Application of TRQI
Recommended Therapeutic Regimens
TRQI has been recommended in 12 therapeutic regimens of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of TRQI
Scutellaria baicalensis Georgi (Huangqin), Ursi fellis pulvis (Xiongdanfen), Forsythia suspensa (Thunb.) Vahl (Lianqiao), and Lonicera japonica Thunb. (Jinyinhua). Basic information on TRQI is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With TRQI
TRQI is used for syndromes of epidemic toxin lung closure and phlegm-heat lung obstruction in the progressive stage of COVID-19 (critical case). Indicative symptoms are fever, cough, cough with difficulty in expectoration, chest distress, and shortness of breath.
Progress of Pharmacological Research on TRQI
Modern pharmacological studies have shown that TRQI is effective against influenza virus, destroys bacterial biofilm, inhibits airway inflammation, and improves lung injury (see Table 3 ).
Research by Jinsu Zheng et al. discovered that TRQI improved pathological injury of lung tissues in mice infected with influenza virus, and had significant antiviral activity in influenza virus infected mice. The antiviral activity of TRQI might be due to its inhibition of cellular proliferation and enhancement of immunity (Zheng and Gu, 2009). Weifeng Yang et al. discovered that TRQI could destroy methicillin-resistant Staphylococcus aureus (MRSA) biofilm and induce its death. When combined with vancomycin or linezolid below the minimal inhibitory concentration (MIC) concentration, synergistic anti-biofilm activity was observed that was significantly higher than when using TRQI alone (Yang et al., 2018). Research by Yi Wang et al. showed that the efficacy of TRQI in the treatment of acute pneumonia was mediated by destruction of bacterial biofilm, which is different to the mechanism of penicillin (Wang Y. et al., 2011). Wei Liu et al. discovered that TRQI might treat airway mucus hypersecretion by regulating the interleukin-17 (IL-17) signaling pathway and its downstream protein MUC5AC. An in vivo experiment showed that TRQI could significantly inhibit excessive secretion of LPS-stimulated MUC5AC and expression of TNF-α, interleukin-6 (IL-6), IL-8, and IL-17A in terms of protein and mRNA levels (Liu W. et al., 2019). Animal experiments conducted by Wei Liu et al. showed that TRQI inhibited airway inflammation caused by LPS through the MAPK/NF-κB pathway, and showed a dose-dependent effect (Liu et al., 2016). Li Wen et al. found that TRQI improved signs and symptoms in AECOPD patients, which might be mediated by reduction of serum IL-8 and neutrophil elastase (NE) levels, and improved airway inflammation and mucus hypersecretion (Li et al., 2010). Research by Li Pengtao et al. discovered that TRQI improved blood flow in capillaries of the alveolar walls while repressing the LPS-induced inflammatory cascade, which was the pharmacological basis for its effective alleviation of acute lung injury and prevention of decreased arterial partial oxygen pressure (Li et al., 2005).
Clinical Research on TRQI
Modern clinical studies have shown that TRQI has therapeutic efficacy against infectious diseases, such as viral pneumonia, MERS, human infection with H7N9 avian influenza, acute bronchitis, acute attack of chronic bronchitis, CAP, tuberculosis accompanied by infection, and AECOPD (see Table 3 ). TRQI has been recommended in MERS Diagnosis and Treatment Scheme (Version 2015) and Diagnosis and Treatment Scheme for Human Infection with H7N9 Avian Influenza (Version 1, 2017).
A systematic evaluation of eight published randomized and controlled trials that included a total of 590 adult patients with viral pneumonia found that TRQI had advantages in terms of response rate, faster change of chest radiography, average length of stay, and other aspects (Pan, 2016). Research results from Jinzhi Liang et al. showed that there was no statistically significant difference in the clinical effect of combined TRQI and Ribavirin or TRQI alone in the treatment of hand-foot-and-mouth disease. Both treatments were superior to that of Ribavirin alone (Liang et al., 2013). Research by Wang Pei et al. showed that potential benefits of TRQI in the treatment of acute bronchitis included improved response rate, and reduced fever, cough, crackles, and X-ray shadow absorption (Wang et al., 2016). Research results of Lini Gao et al. showed that combined use of TRQI and Western medicines was more effective than Western medicines alone in the treatment of acute bronchitis and gave superior improvement of clinical symptoms (Gao et al., 2019). Hongli Jiang et al. showed by systematic evaluation that administration of TRQI to treat CAP on the basis of antibiotics and symptomatic treatment significantly improved clinical symptoms. Cough with expectoration was improved, the duration of fever was shortened and recovery of chest radiography and hemogram were promoted without significant adverse reactions (Jiang et al., 2009). Lian Xiong et al. showed by systematic evaluation that TRQI might have the same overall effect as some antibacterial drugs in treatment of patients with tuberculosis accompanied by lung infection, but improved efficacy was observed in combination with antibacterial drugs. This might be due to the bacteriostatic effects of TRQI and elimination of inflammatory mediators (Lian et al., 2018). A total of 14 trials and 954 patients were included in a study by Yunqing Zhong, and the results showed that combined use of TRQI and antibacterial drugs improved the clinical effects and lung function in AECOPD patients, reduced pCO2, and shortened the length of stay without serious adverse reactions (Zhong et al., 2010).
Usage and Dosage of TRQI
20 ml once for adults, 40 ml once for severe patients, with addition of 250–500 ml 5% glucose or 0.9% sodium chloride; intravenous drip at less than 60 drops per min, once a day.
Adverse Reactions of TRQI
1) Some patients may have dizziness, chest distress, nausea, vomiting, and diarrhea. 2) Flushing, rash or itching and other allergic reactions occasionally. 3) Rarely, palpitations, chill and difficulty breathing. 4) Extremely rarely, allergic shock. 5) Other adverse reactions: dry mouth, fever, periorbital facial edema, discomfort at infusion site.
TRQI Precautions
1) Use is forbidden in those with liver and renal failure; 2) Use is forbidden in those with severe lung and heart disease accompanied by heart failure; 3) Use is forbidden in pregnant women and infants less than 24 months; 4) It should be used alone and must not be mixed with other drugs; 5) Dilution ratio of the liquid shall be no lower than 1:10 (liquid: solvent) and the diluted liquid must be used within 4 h.
Relevant Information on the Clinical Application of XYPI
Recommended Therapeutic Regimens
XYPI has been recommended in 15 therapeutic regimens of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of XYPI
Andrographolide total sulfonate. Basic information on XYPI is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With XYPI
XYPI is used for syndrome of exuberance of internal heat toxin in progressive stage of COVID-19 (critical case). Indicative symptoms are fever, sore throat, cough with yellow phlegm and chest distress. It could also be used to treat viral infection combined with mild bacterial infection.
Progress of Pharmacological Research on XYPI
The main ingredient of XYPI is andrographolide total sulfonate, which is antipyretic, anti-inflammatory, antiviral, antibacterial and immune-regulatory (see Table 3 ).
Yang Yu et al. conducted in vivo experiments with XYPI, and discovered that it could significantly protect mice infected with Staphylococcus aureus and Streptococcus pneumoniae, and significantly inhibited citric acid-induced cough frequency in guinea pigs (Yu et al., 2009). Using in vitro experiments, Lu Wang et al. studied the inhibitory effect of XYPI on inflammatory factors released by LPS-stimulated mouse mononuclear macrophages. The results showed that XYPI significantly inhibited the release of inflammatory factors such as TNF-α and IL-6 (Wang et al., 2008). Yinglan Nie et al. explored the mode of action of XYPI in the treatment of acute lung injury by observing its effect on cytokine content in bronchoalveolar lavage fluid (BALF) following LPS-induced acute lung injury. The results showed that XYPI could play an anti-inflammatory role by modulating the balance of pro-inflammatory/anti-inflammatory cytokines and prevent excess anti-inflammatory responses during the course of acute lung injury (Nie et al., 2012). Qi Liu et al. observed antiviral activity of XYPI against human rhinovirus-induced mouse infections. XYPI significantly reduced the virus titer in trachea-lung tissue homogenate of infected mice, effectively inhibiting proliferation of human rhinovirus in mice. Respiratory lesions were alleviated in tested animals, survival rate was improved, there were few adverse reactions, and it was an efficient and safe drug against human rhinovirus infection. Its specific mode of action, however, was unclear (Liu, 2015).
Clinical Research on XYPI
XYPI is a broad-spectrum antiviral Chinese patent medicine that is widely used to treat acute URI, viral pneumonia and pulmonary infection in clinical practice with good efficacy. Recent studies have discovered that it can also inhibit some viruses and bacteria, and could be used to treat influenza, human infection with H7N9 avian influenza, capillary bronchitis and other diseases (see Table 3 ). XYPI has been recommended in China’s Diagnosis and Treatment Scheme for Human Infection with H7N9 Avian Influenza (Version 2017).
Xiuping Yin et al. used the association rule method to analyze drug combinations, including XYPI in patients with pulmonary infection. The results showed that it could play a role as alternative or as a supplement to antibiotics in the treatment of pulmonary infection, but the safety and rationality of its use in drug combinations required further study in clinical practice (Yin et al., 2015). Guangming Li et al. conducted a retrospective analysis of 92 patients with viral pneumonia and found that XYPI was more effective than Ribavirin, providing significant improvement of symptoms (Li, 2015). Ruihan Qi et al. analyzed the therapeutic effect of XYPI in the treatment of viral pneumonia by systematic evaluation and found that it was more effective than Ribavirin. XYPI increased the cure rate, improved signs and symptoms, and reduced the incidence of adverse reactions (Qi et al., 2018). Lili Zhang et al. used XYPI in combination with Western medicine to treat severe pneumonia of the elderly in clinical practice. The results showed that it significantly shortened the course of disease, improved treatment efficiency, reduced the incidence of antibiotic resistance, reduced occurrence of double infection, improved the prognosis, and reduced mortality (Zhang and Wang, 2015). Zhixu Yang et al. observed the clinical effect of XYPI in treating the syndrome of phlegm-heat obstructing lung of severe pneumonia from the perspective of traditional Chinese medicine. The results showed significant improvements that included reduced fever, reduced numbers of leukocytes, improved oxygen index, lower clinical pulmonary infection score (CPIS), and reduced pulmonary inflammation. It also shortened the duration of mechanical ventilation and length of stay in ICU, and improved the clinical effect (Yang et al., 2014). In addition, XYPI has also shown significant efficacy in the treatment of URI. Xiaowen Liu et al. conducted a retrospective analysis of 660 patients with acute URI and found that the total response rate in the XYPI treatment group was significantly higher than that of the control group. The difference was statistically significant (Liu and Li, 2015).
Usage and Dosage of XYPI
1) Intramuscular injection. Adults: 50-100 mg, 2 or 3 times a day. 2) Intravenous drip. Adults: 250–500 mg a day, diluted with 0.9% sodium chloride or 5% glucose.
Adverse Reactions of XYPI
The main adverse reactions are allergic reaction, damage to the skin, damage to the digestive system, damage to the respiratory system, and general damage to the cardiovascular system. These are manifested by rash, itching, shivering, facial blushing, fever, cyanosis, difficulty breathing, nausea, vomiting, palpitations, chest distress, and allergic shock.
XYPI Precautions
1) Use is forbidden in pregnant women and children under 1 year of age. Use with caution in the elderly above 75 years of age. 2) Use is forbidden in those with a history of allergic or severe adverse reactions to this drug or preparations containing andrographolide total sulfonate. 3) Enhanced monitoring is recommended in patients using XYPI for the first time; pay close attention to reactions during administration, especially if discovering abnormalities within 30 min of administration. Stop administration immediately and take active rescue measures. 4) When used in combination with other injections, XYPI should be administered first. Other injections can be infused after flushing or replacing the infusion tube.
Relevant Information on the Clinical Application of XBJI
Recommended Therapeutic Regimens
XBJI has been recommended in 20 therapeutic regimens of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of XBJI
Carthamus tinctorius L. (Honghua), Paeonia lactiflora Pall. (Chishao), Conioselinum anthriscoides ‘Chuanxiong’ (Chuanxiong), Salvia miltiorrhiza Bunge (Danshen), and Angelica sinensis (Oliv.) Diels (Danggui). Basic information on XBJI is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With XBJI
XBJI is used for syndrome of blood-stasis and toxins in the progressive stage of COVID-19 (critical case). Indicative symptoms are fever, dyspnea and tachypnea, palpitations, and dysphoria. It could also be used for treatment of infection-induced systemic inflammatory response syndrome and multiple-organ dysfunction syndrome in the stage of impaired organ function.
Progress of Pharmacological Research on XBJI
Modern pharmacological studies have shown that XBJI is anti-inflammatory, antioxidant, immune-regulatory, and protects against acute lung injury (see Table 3 ).
Tiantian Li et al. found that in mice with MRSA-induced sepsis, XBJI protected the infected mice by downregulating expression of inflammatory cytokines stimulated by Pam3CSK4, MAPK, PI3K (phosphatidylinositol 3 kinase)/Akt and other pathways, thus, inhibiting the inflammatory response (Li T. T. et al., 2020). Shuwen Zhang et al. and Xi Chen et al. found that XBJI significantly reduced TNF-α, IL-6, and IL-10 levels in mice with sepsis, prevented neutrophil infiltration of lung and kidney, modulated T helper cell (Th) 1/Th2, Th17, and Tregs balance, reduced inflammatory response, and improved survival rate in mice with infectious shock (Zhang et al., 2006; Chen et al., 2018). Mingwei Liu et al. studied rats with paraquat-induced acute lung injury and discovered that XBJI could enhance immunity, reduce expression of inflammatory factors, and protect against acute lung injury by blocking p-38 MAPK and NF-κB p65 pathways, (Liu et al., 2014). Research by Yin Teng et al. found that XBJI in combination with conventional treatment significantly reduced interleukin-1 (IL-1), IL-6, and TNF-α levels, improved CD4+/CD8+ T lymphocyte ratio and NK cell relative activity, reduced inflammatory response, and enhanced cellular immunity in patients with severe pneumonia (Teng et al., 2012). Research by Hui Jin et al. showed that XBJI significantly improved the activity of superoxide dismutase (SOD), reduced reactive oxygen species (ROS) levels and protected against oxidative damage in mice under high-temperature stimulation (Jin et al., 2018). Research by Luo Peng et al. showed that XBJI downregulated MDA levels, upregulated SOD levels, and alleviated LPS-induced acute lung injury in rats (Luo and Zhou, 2017). In a rat model of oleic acid or LPS-induced acute lung injury, XBJI reduced TNF-α levels, alleviated pulmonary tissue edema and inflammatory cell infiltration, and protected against lung injury (Zhang et al., 2014). Research by Yuexia Ma et al. showed that although XBJI had no direct antiviral effect in mice with H1N1 severe pneumonia; it alleviated lung injury and protected against death, which might be due to its regulation of inflammatory cytokine levels in the early stage (Ma et al., 2015).
Clinical Research on XBJI
Modern clinical studies have shown that XBJI in combination with conventional treatment has therapeutic effects in relevant diseases, such as MERS, human infection with H7N9 avian influenza, CAP, severe pneumonia, systemic inflammatory response syndrome, COPD and sepsis (see Table 3 ). XBJI has been recommended in MERS Diagnosis and Treatment Scheme (Version 2015) and Diagnosis and Treatment Scheme for Human Infection with H7N9 Avian Influenza (Version 1, 2017).
Clinical research by Wen Long et al. randomly divided 60 severe COVID-19 patients into routine treatment (n = 20), XBJI 50 ml (n = 20), and XBJI 100 ml (n = 20) groups. On the basis of conventional treatment, XBJI (50 ml) was injected twice a day for 7 days in the XBJI 50 ml group, or 100 ml twice a day for 7 days in the XBJI 100 ml group. After treatment, the white blood cell count (WBC) and lymphocyte count (LYM) of the three groups increased, while CRP and ESR decreased. Compared with the routine treatment group, the WBC count in the XBJI 100 ml group after treatment significantly increased (×109/L: 7.12 ± 0.55 vs. 5.67 ± 0.51, p < 0.05), and the levels of CRP and ESR in the XBJI 50 ml and 100 ml groups significantly decreased [CRP (mg/L): 32.3 ± 4.6, 28.0 ± 6.2 vs. 37.3 ± 5.9; ESR (mm/h): 45.9 ± 5.7, 40.5 ± 7.4 vs. 55.3 ± 6.6, all p < 0.05]. Compared with the XBJI 50 ml group, the increase of WBC, and the decrease of CRP and ESR were more significant in the XBJI 100 ml group [WBC (×109/L): 7.12 ± 0.55 vs. 5.82 ± 0.49; CRP (mg/L): 28.0 ± 6.2 vs. 32.3 ± 4.6; ESR (mm/h): 40.5 ± 7.4 vs. 45.9 ± 5.7, all p < 0.05]. The APACHE II score of three groups decreased. In the XBJI 100 ml group, the APACHE II score after treatment was significantly lower than those in the routine treatment and XBJI 50 ml groups (12.3 ± 1.5 vs. 16.5 ± 1.6, 15.9 ± 1.4, both p < 0.05). After treatment, the 2019-nCoV nucleic acid test in the three groups partly turned negative: nine cases in the routine treatment group, eight cases in the XBJI 50 ml group and nine cases in the XBJI 100 ml group, with no significant differences (p > 0.05). The conditions of patients in the three groups were improved after treatment. Eight cases in the routine treatment group were transformed into common type and one case into critical type; nine cases and 12 cases in the XBJI 50 ml and 100 ml groups, respectively, were transformed into the common type. Patients in the XBJI 100 ml group improved more obviously than in the XBJI 50 ml and routine treatment groups (both p < 0.05). The XBJI injection can effectively improve the inflammatory markers and prognosis of severe COVID-19 patients (Wen et al., 2020).
Clinical research by Qi Fei et al. showed that, of 80 patients with severe pneumonia, those receiving a combination of XBJI and conventional treatment exhibited reduced levels of blood LDH, α1-acid glycoprotein (α1-AG) and α1-antitrypsin (α1-AT). Body temperature was reduced significantly and secretion of TNF-α, IL-6, IL-8, and other cytokines was inhibited. The total treatment efficiency was up to 80%, compared to 67.5% in the control group (Qi et al., 2011). An RCT study comprised of 33 centers and 710 patients conducted by Yuanlin Song et al. showed that XBJI in combination with conventional treatment significantly improved the primary endpoint, pneumonia severity index, in patients with severe CAP (the control group vs XBJI Group, 46.33% vs 60.78%, p < 0.001). There was also significantly reduced mortality in 28 days (24.65% vs 15.87%, p = 0.006), the duration of mechanical ventilation was shortened (11 vs 16.5 d, p = 0.012) and length of stay in ICU was reduced (12 vs 16 d, p = 0.004) (Song et al., 2019). Mingjin Zhu et al. conducted a meta-analysis of 12 studies with a total of 860 patients and showed that XBJI in combination with conventional treatment was superior to the treatment group in improving total response rate in patients with severe pneumonia. Infectious indicators (WBC, CRP, CPIS) and inflammatory cytokine (IL-6, IL-8, TNF-α) levels were reduced, and the average length of stay in hospital was reduced (Zhu et al., 2014). Wei Zhao et al. studied 56 patients with systemic inflammatory response syndrome (SIRS) and found that after 7 d treatment with XBJI in combination with conventional treatment, body temperature, WBC, and acute physiology and chronic health evaluation II (APACHE-II) score improved more significantly compared to the control group (p < 0.05). Expression of CD4+, CD4+/CD8+, CD14+/HLA-DR (human leukocyte antigen-DR) increased significantly, and the combination regulated the SIRS immune state and improved systemic status of the patients (Zhao W. et al., 2014). Clinical research found that XBJI in combination with conventional treatment lowered TNF-α, CRP, and other inflammatory indicators in AECOPD patients and had a certain therapeutic effect. In patients with accompanying SIRS, the combination significantly improved cough, expectoration, shortness of breath, and other clinical symptoms, and shortened hospital stay (Chen et al., 2011; Zhu et al., 2019). Meta-analysis by Chengyu Li et al. included sepsis patients from 16 RCTs (total 1,144 cases), and evidence of moderate intensity showed that XBJI in combination with conventional treatment effectively reduced the mortality rate of sepsis patients over 28 d (934/1144, p < 0.00001), APACHE-II score (792/1144, p < 0.00001) and body temperature (362/1144, p < 0.00001) (Li et al., 2018).
Usage and Dosage of XBJI
Intravenous injection. 1) Systemic inflammatory response syndrome: 50 ml plus 100 ml 0.9% sodium chloride injection for intravenous drip, completed in 30–40 min, twice a day. Three times a day for severe patients. 2) Multiple-organ dysfunction syndrome: 100 ml plus 100 ml 0.9% sodium chloride injection for intravenous drip, completed in 30–40 min, twice a day. Three or four times a day for severe patients.
Adverse Reactions of XBJI
Allergic reactions: skin flush, rash, itching, palpitations, cyanosis, laryngeal edema, allergic shock, etc. Cardiovascular system: palpitations, cyanosis, increase, or decrease of blood pressure, arrhythmia. Nervous system: dizziness, headache. Respiratory system: difficulty breathing, chest distress, labored breathing, shortness of breath, and cough. Digestive system: nausea, vomiting, stomach ache, diarrhea, and abnormal liver function. Others: facial edema, conjunctival congestion, abnormal tears, phlebitis, lumbago, backache, and local numbness.
XBJI Precautions
1) Not for use in pregnant women and children under 14 (inclusive) years of age. 2) The product must not be mixed with others, and must be used with caution in combination with others. When used in combination with other drugs, 50 ml 0.9% sodium chloride injection must be used between doses. 3) Allergic history, family allergic history and patient history of medications should be queried before administration. 4) During administration, special attention should be given to the initial 30 min of intravenous drip. In case of abnormality, the drug should be discontinued immediately and symptomatic treatment administered. 5) Monitoring of administration should be enhanced in older patients and in patients receiving TCM injection for the first time.
Relevant Information on the Clinical Application of SFI
Recommended Therapeutic Regimens
SFI has been recommended in 19 therapeutic regimens of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of SFI
Panax ginseng C.A.Mey. (Hongshen) and Aconitum carmichaeli Debeaux (Fuzi). Basic information on SFI is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With SFI
SFI is used for deliverance due to sudden yang deficiency in the progressive stage of COVID-19 (critical case). Indicative symptoms are dyspnea, pale complexion, and severe symptoms are unconsciousness, drip sweat, and cold limbs.
Progress of Pharmacological Research on SFI
Modern pharmacological studies have shown that SFI has functions, including anti-shock, and protection from lung injury (see Table 3 ).
Yuhang Ai et al. explored the effects and mechanism of SFI in an LPS-induced lung injury model in rats. The results indicated that SFI might protect the lung by reducing activation of NF-κB in lung tissue (Ai et al., 2006). Research by Xia Liu et al. found that SFI improved the inflammatory response of rat lung tissue in an LPS shock model by reducing expression of p65 and p50 mRNA and protein in lung tissue and serum TNF-α (Liu et al., 2019a). Li Lin et al. studied the impact of SFI on LPS acute lung injury in rats, and found that SFI significantly increased the wet/dry weight ratio (W/D) of lung tissue, neutrophil ratio in BALF, protein content, lung tissue MDA, and serum NO. It significantly alleviated injury in lung tissue, indicating that SFI had an important preventive and therapeutic effect on LPS-induced acute lung injury (Lin and Zhan, 2010). Xi Liu et al. used the LPS intravenous injection method to establish a septic shock model in rabbits. Administration of SFI significantly improved mean arterial pressure (MAP), reduced LPS, LDH, and AST serum levels, and significantly improved the morphology of heart, liver, and kidney. In addition, SFI increased levels of adenosine triphosphate (ATP) and taurine in the heart, while reducing the level of adenosine monophosphate (AMP) in the heart. The results showed that SFI had a significant protective effect against LPS-induced septic shock (Liu et al., 2019b).
Clinical Research on SFI
SFI is composed of Panax ginseng C.A.Mey. and Aconitum carmichaeli Debeaux, and has properties that include enhancing cardiac function, increasing blood pressure, and protecting ischemic myocardium. It is widely used to rescue from shock (infectious or cardiogenic shock) caused by various reasons, cardiac failure, and arrhythmia in clinical practice. Recent studies have shown that SFI significantly protects against lung injury (see Table 3 ). SFI has been recommended in China’s SARS Diagnosis and Treatment Scheme (Version 2004), the MERS Diagnosis and Treatment Scheme (Version 2015), and the Diagnosis and Treatment Scheme for Human Infections with H7N9 Avian Influenza (Version 2017).
Qiu Z.L. et al. observed a therapeutic effect of SFI in patients with severe sepsis and an impact on the expression levels of serum IL-6 and IL-10. They found that SFI significantly lowered IL-6 levels in patients with severe sepsis and regulated the balance between pro- and anti-inflammatory factors, thus, improving the therapeutic effect (Qiu et al., 2012). Ning Zhang et al. randomized 160 patients with sepsis into an SFI treatment group and a conventional treatment group. By collecting post-treatment immunological parameters, they conducted a comparative analysis of the impact on immune function. The results showed that patients in the SFI treatment group had increased CD4+ and CD8+ T cell counts in peripheral blood and upregulated HLA-DR expression in monocytes. In addition, the SFI treatment group had a better response than the control group for duration of vasopressor administration and APACHE-II score. The results showed that SFI enhanced cellular immune function in patients with septic shock and might become an important adjunctive therapy for sepsis patients (Zhang et al., 2017). Another study found that SFI played an active role in the treatment of severe pneumonia in the elderly. Among 89 elderly patients with severe pneumonia, the SFI treatment group had significantly decreased levels of TNF-α, IL-6, and IL-8 7 days after administration, indicating that SFI effectively reduced inflammatory mediators, thus, playing an active therapeutic effect (Lv et al., 2017). Min Ma et al. conducted clinical research on 80 patients with traumatic acute lung injury, and found that SFI significantly improved respiratory rate, improved the oxygen index, and reduced levels of intracellular adhesion molecule 1 (ICAM-1), endothelin-1 (ET-1), and NO, thus, improving prognosis of these patients. This study provided a potential new therapy for traumatic acute lung injury (Ma et al., 2019). Jie Li et al. observed an impact of SFI intervention on duration of mechanical ventilation in patients with respiratory failure. The results showed that the total response rate in the SFI group was higher than that of the control group. SFI significantly improved serum prealbumin and high-sensitivity CRP levels in patients with respiratory failure and improved their oxygen index, thus, shortening the duration of mechanical ventilation (Li, 2013).
Usage and Dosage of SFI
1) Intravenous drip: 20–100 ml, diluted in 250–500 ml of 5%–10% glucose injection. 2) Intravenous injection: 5–20 ml, diluted in 20 ml of 5%–10% glucose injection.
Adverse Reactions of SFI
Dizziness, headache, shivering, fever, palpitations, chest distress, chest pain, difficulty breathing, nausea, retching, abdominal pain, rash, itching, rash or swelling, pain, and other discomfort in local infusion site.
SFI Precautions
1) To be used with caution in pregnant women. 2) Avoid direct mixing with coenzyme A, VitK3, and aminophylline. 3) Prepared drug should be used within 4 h.
Relevant Information on the Clinical Application of SMI
Recommended Therapeutic Regimens
SMI has been recommended in 18 therapeutic regimens of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of SMI
Panax ginseng C.A.Mey. (Hongshen) and Ophiopogon japonicus (Thunb.) Ker Gawl. (Maidong). Basic information on SMI is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With SMI
SMI is used for the syndrome of deficiency of both qi and yin and deficiency of pulse in the progressive stage of COVID-19 (critical case). Indicative symptoms are weakness and shortness of breath, tachypnea, palpitations, dry mouth, sweating, and even dysphoria and cold limbs.
Progress of Pharmacological Research on SMI
Modern pharmacological studies have shown that SMI has functions that include protection from inflammatory shock, protection of heart and lung function, and immunoregulation (see Table 3 ).
Y. Z. Zhang et al. observed that SMI had strong anti-shock and neuroprotective properties in LPS-induced shock, possibly due to inhibition of brain lipid peroxidation and improvement of SOD activity (Zhang Y. Z. et al., 2010). SMI suppressed apoptosis of lung tissue cells during pulmonary ischemia/reperfusion injury in rabbits, resulting in attenuation of pneumocyte injury by raising NO levels, lowering oxygen free radical levels, and decreasing lipid peroxidation (Lin et al., 2007). It has also been reported that SMI reduced expression of NF-κB and activity of inducible nitric oxide synthase (iNOS) in lung tissues of rats poisoned by paraquat, and significantly alleviated erythrocyte diapedesis in the alveolar space (Liu et al., 2009). Research by Shuhua Xu et al. showed that SMI improved cardiac function and significantly improved hemodynamics in rats with cardiac failure. In addition, it improved the oxygen supply to tissues and the capacity of the tissues to use oxygen, thus, improving oxygen metabolism (Xu and Liu, 2010). SMI also inhibited expression of ICAM-1 and vascular cell adhesion molecule 1 (VCAM-1) to alleviate inflammatory infiltration following ischemia/reperfusion, and alleviated myocardial ischemia/reperfusion injury caused by multiple inflammatory responses (Liu et al., 2015). It also inhibited generation of inflammatory cytokines in rats subjected to ischemia/reperfusion, reduced serum expression of TNF-α, IL-6, IL-8, etc., thus, alleviating inflammatory factor-induced cardiomyocyte injury and improving immune function (Wang et al., 2015). Research by Xuan Liu et al. discovered that SMI inhibited MCP-1, which indicated that SMI might be important in the inhibition of monocyte and macrophage activation (Liu et al., 2015). Lihua Du discovered that SMI significantly increased the weights of thymus and spleen in mice, raised serum IgG levels and the number of T cells, enhanced the phagocytic function of macrophages and had a significant immunomodulatory effect.
Clinical Research on SMI
SFI has often been used to treat shock caused by various factors, COPD, systematic inflammatory response syndrome and other diseases in clinical practice (see Table 3 ). SMI has been recommended in China’s SARS Diagnosis and Treatment Scheme (Version 2004) and MERS Diagnosis and Treatment Scheme (Version 2015).
Biao Deng et al. studied 71 patients with shock and found that SMI in combination with conventional Western medicine had definite therapeutic efficacy, shortened the course of disease, reduced the length of hospital stay, and lowered the fatality rate (Deng et al., 2006). Hefeng Qin observed 68 patients with infectious shock and found that SMI had good clinical efficacy. It significantly improved CRP, PCT and TNF-α serum levels, and shortened the recovery time of vital signs with few adverse reactions (Qin, 2014). Wang Xian’an et al. observed 80 patients treated for infectious shock, and discovered that SMI in combination with ulinastatin had a significant therapeutic effect, enhancing immune function, and alleviating the inflammatory response (Wang et al., 2017). X. Huang et al. evaluated 23 RCTs with a total of 1,804 participants to study the impact of SMI on COPD. The results showed that SMI not only increased the total clinical response rate, but also improved pulmonary function, blood gas, and IgG indexes, and shortened the time for disappearance of lung rales. The results indicated that SMI in combination with Western medicine might have a positive effect in the treatment of COPD (Huang et al., 2019). Zongjun Fang et al. studied 38 patients with COPD. The control group (18 cases) received conventional Western medicine, while 20 cases (the treatment group) received SMI in addition. The results showed that patients in the treatment group had better vital capacity, forced expiratory volume in 1 s (FEV1), maximal breathing capacity (MBC), maximal inspiratory pressure (MIP), load breathing time, arterial blood gas analysis, and Burp dyspnea scores than the control group or the pre-treatment patients. The treatment group also had significantly improved respiratory function and clinical symptoms (Fang et al., 1998). Changxing Guo et al. randomized 33 patients with systemic inflammatory response syndrome into a conventional Western medicine treatment group (15 cases) and SMI + conventional treatment group (18 cases). After treatment, patients in the SMI treatment group had increased prostacyclin PGI2 and PGI2/thromboxane A2 (TXA2) in blood to a certain extent compared to patients in the conventional treatment group. Patients in the SMI group also had decreased levels of TXA2, atrial natriuretic peptide (ANP) and endothelin, and there were significant differences between the two groups. The results indicated that SMI could play an active role in improving microcirculation, protecting organ functions, and preventing further occurrence and development of systemic inflammatory response syndrome (Guo et al., 2004).
Usage and Dosage of SMI
Intravenous drip, 20–60 ml diluted with 250–500 ml of 5% glucose injection.
Adverse Reactions of SMI
The adverse reactions mainly include immediate hypersensitivity, predominantly skin allergy manifested by itching, rash, systematic urticaria, and then allergic shock; there may also be serious abdominal distension, corneal edema, abnormal vision, hypotension, ascending vascular pain, acute hepatic damage, sinus arrest, and drug fever.
SMI Precautions
1) Not to be used in newborns, infants, pregnant women, or those with an allergic constitution. 2) Not for administration by intravenous injection. The administration speed should not be too fast. In those receiving the drug for the first time, the initial administration should be at 15 drips/min for 10 min. If there are no abnormalities, the speed of administration can be increased to normal, which is generally controlled at 40–50 drips/min. 3) This drug has a pressor response, and blood pressure should be monitored in hypertensive patients.
Relevant Information on the Clinical Application of AGNHP
Recommended Therapeutic Regimens
AGNHP has been recommended in 21 therapeutic regimens of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of AGNHP
Curcuma kwangsiensis S.G.Lee & C.F.Liang (Yujin), Calculus Bovis (Niuhuang), Cornu Bubali (Shuiniujiao), Coptis chinensis Franch. (Huanglian), Cinnabaris (Zhusha), Moschus (Shexiang), Margarita (Zhenzhu), Realgar (Xionghuang), Scutellaria baicalensis Georgi (Huangqin), Gardenia jasminoides J.Ellis (Zhizi), and Cinnamomum camphora (L.) J.Presl (Bingpian). Basic information on AGNHP is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With AGNHP
AGNHP is used for the syndrome of epidemic toxin lung closure and inner blocking causing collapse in the progressive stage of COVID-19 (critical case). Indicative symptoms are hyper-pyretic convulsions, coma and delirium, difficulty breathing, and dysphoria.
Progress of Pharmacological Research on AGNHP
Modern pharmacological studies have shown that AGNHP has antipyretic, analgesic, anti-inflammatory, and neuroprotective effects (see Table 3 ).
Zuguang Ye et al. discovered that AGNHP could significantly reduce the body temperature of hyperpyrexic rabbits in a fever model induced by intravenous injection of typhoid Vi polysaccharide vaccine in rabbit ear (Ye et al., 2003). Feng Zhang, Kunjie Zhu et al. found in an LPS-induced intracerebral inflammation model that AGNHP antagonized the toxic effect of LPS on dopaminergic neurons, inhibited release of superoxide radical, and reverse changes in cortical monoamine neurotransmitters. It was speculated that its impact on cortical monoamine neurotransmitters might be one of the mechanisms by which AGNHP promoted consciousness in LPS brain damage (Zhang F. et al., 2010; Zhu and Sun, 2014). Research by Dan Zhang et al. showed that AGNHP lowered serum LPS and lung myeloperoxidase (MPO) levels in a rat model of sepsis (Zhang et al., 2009). Yishan Tang et al. found that AGNHP lowered total LDH activity in serum and brain tissue, and changed the percentage of isomerase in a rat pertussis-induced infectious cerebral edema model (Tang et al., 2005). Fan Q et al. discovered that AGNHP had anti-atherosclerotic effects in the high fat diet-induced ApoE−/− mouse model at early- and mid-stage via regulation of Th17/Treg balance. It inhibited chronic inflammation, reduced plaque collagen fibers, and reduced inflammatory cell infiltration (Fan et al., 2020).
Clinical Research on AGNHP
Modern clinical studies have shown that AGNHP has therapeutic effects against hyperpyrexia, coma caused by severe infectious diseases, and viral encephalitis and severe pneumonia of infants (see Table 3 ).
Yueming Feng et al. conducted a systematic evaluation and found that AGNHP could be used to promote consciousness of coma patients with acute cerebral infarction (ACI) and improve neurologic function. This may be due to the ability of AGNHP to alleviate the inflammatory response, reduce cerebral edema, and promote recovery of neurologic function (Feng and Yang, 2015). Haijun Zhang et al. discovered through clinical observation that AGNHP could be used to treat viral encephalitis in children. AGNHP rapidly reduced body temperature, prevented convulsions, promoted consciousness, and alleviated cerebral edema and brain cell damage (Zhang and Dong, 2014). Research by Zhulin Zhuo et al. found that AGNHP with the adjuvant, Ribavirin was efficacious in acute severe viral pneumonia of children, significantly reduced PCT and improved immune function (Zhuo and Wen, 2017). Yanling Shi discovered through clinical observation that AGNHP in combination with sodium phosphate improved anoxic conditions and myocardial damage in patients with neonatal asphyxia and myocardial damage (Shi, 2019). Xie Long et al. in a study of 70 patients with ACI and central hyperpyrexia found that combined use of conventional Western medicine and AGNHP reduced the duration of fever and significantly improved the prognosis (Long and Wu, 2014). Hanwei Liu et al. conducted a systematic review of relevant literature on AGNHP treatment of ACI and cerebral hemorrhage. The results showed that adjuvant treatment with ANP (AGNHP) appeared to improve the total response rate and neurologic deficit score in patients with ACI and acute intracerebral hemorrhage (AIH) (Han et al., 2019). Research by Ma et al. showed that ANP had a moderating effect on Th1/Th2 in cerebral infarction patients (Ma and Zhou, 2015).
Usage and Dosage of AGNHP
Oral administration. 3 g, once a day.
Adverse Reactions of AGNHP
Overdose administration might cause mercurial nephrosis or allergic reaction and other adverse reactions. Improper use of this product might cause hypothermia.
AGNHP Precautions
1) Nasogastric administration can be used in patients unable to take orally because of high fever and coma. The pills can be dissolved in warm but not hot water. The water or decoction used to dissolve the pills should be controlled at 40–60°C. The use of boiling water is forbidden for two reasons: first, to avoid increased decomposition of realgar and cinnabar by high temperature, and reduce generation of the highly toxic arsenic trioxide, free arsenium, and mercury. Research has shown that arsenic trioxide in realgar preparations is not significantly changed below 60°C but begins to increase at 80°C. The decoction used for dissolving AGNHP should therefore not exceed 60°C secondly, musk, borneol and other aromatic substances are volatile. Boiling water could result in excess volatilization, thus, reducing efficacy. 2) Must not be used with nitrate, nitrite, ferrite or sulfate drugs. 3) Not for use in pregnant women. 4) It contains cinnabar and realgar, and should not be taken at high doses for long periods. Should be used with caution in those with hepatic and renal dysfunction. (5) It contains musk, so athletes should use with caution.
Discussion and Conclusions
It is a critical moment in the battle to defeat the current outbreak of novel coronavirus. For this specific indication, rapid performance of TCM can contribute as an alternative measure. TCM can effectively prevent the disease from transforming into severe and critical disease. In severe cases, TCM has won time for recovery by improving symptoms (The State Council Information Office of the People’s Republic of China, 2020). Treatment practice for COVID-19 has shown that early intervention with TCM is an important method to improve cure rate, shorten the course of disease, delay disease progression and reduce mortality rate. For example, the total response rate of Qingfei Paidu Decoction was more than 90% in Shanxi and Hebei provinces (He et al., 2020).
CPMs have played an important role in preventing and treating epidemic diseases in China because they are convenient to use, easily stored and cost-effective. The positive role of CPMs has been emphasized in the “Diagnosis and Treatment of COVID-19 (Trial Version 7)” and other therapeutic regimens. During the medical observation period and early stage of COVID-19, HXZQC, LHQWC, SFJDC, and JHQGG can be selected according to different clinical manifestations. At the same time, they can also promote immunity against the virus. For severe and critical disease, the choice shall be made according to different syndromes during clinical treatment. For viral infections combined with mild bacterial infections, XYPI and TRQI can be used; for high fever with disturbance of consciousness, AGNHP can be used; for systemic inflammatory response syndrome or multiple organ function failure, XBJI is recommended; SMI can be used for immunosuppression; and SFI can be used for shock. Furthermore, the reason that TCM works is not only because it inhibits the virus, but also because it might block infection, regulate the immune response, inhibit the inflammatory storm, and promote repair of the body. Moreover, the prevention and control measures of COVID-19 have fully reflected the ideology of “preventive treatment of disease”.
Physicians should pay attention to the reasonable application of CPMs to treat COVID-19. Severe patients are prone to septic shock, and liver and kidney dysfunction. In patients with related underlying diseases, drug metabolism and clearance are reduced. Treatment options: hepato-renal toxic drugs should be avoided to reduce the risk of drug accumulation and poisoning. For example, AGNHP contains cinnabar and realgar, and should not be taken for a long time. People with liver and kidney dysfunction should use with caution. TRQI should be carefully selected because it aggravates liver and kidney function; LHQWC and JHQGG contain ephedrae herba (Mahuang), and doctors need to monitor patients’ blood pressure, heart condition and combined use of antihypertensive drugs. In clinical application of XBJI, SFI and other traditional Chinese medicine injections, attention should be paid to the choice of solvent and the interval between infusions with other drugs. As is well known, clinicians use CPMs under the guidance of the theory of TCM. Foreign doctors and patients wishing to use CPMs to treat COVID-19 should exercise caution, especially in countries where they may be used incorrectly without the knowledge of TCM theory.
There are some limitations within this paper. First, as there is little direct clinical evidence for the prevention of COVID-19, the reported studies are from previous reports on the prevention of SARS, MERS, H7N9, and H1N1 influenza by CPMs, which can only be considered as indirect evidence in respect of the current outbreak. Secondly, the programs for prevention of COVID-19 were issued shortly after the outbreak. Chinese medicine experts suggested CPMs to treat COVID-19 based on their previous experience in the prevention and treatment of similar diseases combined with their initial understanding of the disease. The actual effects of these programs need to be verified in clinical application, and updated and improved according to the evidence of new research on COVID-19.
For future studies, we recommend prospective cohort studies, RCTs or registry studies to evaluate the effect of CPMs in prevention of COVID-19. Some clinical trial protocols to treat COVID-19 using the top 10 CPMs are ongoing (see Table 4 ). At present, since COVID-19 has not yet been controlled, a series of prospective population studies with rigorous design and large sample should commence with protocol registration, and implementation in a timely manner, to produce reliable evidence for CM prevention of COVID-19 or similar emerging respiratory infectious diseases in the future.

Introduction
COVID-19 is an emerging and rapidly evolving epidemic. The cumulative number of confirmed cases globally reached 1,040,772 on April 4, 2020, comprising 149,790 (14.39%) cured cases, and 55,698 (5.35%) deaths. The causative organism has been designated as the 2019 novel coronavirus (2019-nCoV). On January 30, 2020, the epidemic was declared a public health emergency of international concern by the World Health Organization (WHO) (Fisher and Heymann, 2020). On February 11, 2020, the WHO Director-General, Tedros Adhanom Ghebreyesus, announced that the disease caused by this new coronavirus was “COVID-19,” which is an acronym for “coronavirus disease 2019.” The virus seems to be highly contagious and had quickly spread to 119 countries and regions by March 12, 2020. The clinical spectrum of COVID-19 varies from asymptomatic or paucisymptomatic forms to clinical symptoms characterized by respiratory failure that necessitates mechanical ventilation and support in an intensive care unit (ICU), to multiorgan and systemic manifestations in terms of sepsis, septic shock, and multiple organ dysfunction syndromes (MODS) (Wu and McGoogan, 2020). Currently, there is no effective anti-coronaviral drug that is recommended for treatment of COVID-19, and no vaccine is available. There is no evidence supporting the efficacy of broad-spectrum antibiotics, gamma globulin, interferon, or corticosteroid therapy for COVID-19. Treatment is symptomatic, and oxygen therapy represents the major intervention for patients with severe infection. Mechanical ventilation may be necessary in cases of respiratory failure refractory to oxygen therapy (Huang et al., 2020; Zhang et al., 2020).
Traditional Chinese Medicine (TCM) has a long history and has played an important role in the prevention and treatment of serious epidemic diseases. During the development of the COVID-19 epidemic, more than 3,100 TCM medical staff were deployed to Hubei province, and TCM was included in the guidelines for the diagnosis and treatment of COVID-19. Currently, the total number of confirmed cases treated by TCM has reached 60,107 (Gao, 2020). The decoctions, CPMs, acupuncture, and other TCM treatments have been comprehensively used for treatment, mainly based on syndrome differentiation. Specific CPMs have been widely employed to treat COVID-19 with remarkable therapeutic effects (National Health Commission of the People’s Republic of China and National Administration of Traditional Chinese Medicine, 2020).
CPMs are approved by the National Drug Regulatory Authority of China and processed according to prescribed methods using Chinese herbal medicines as raw materials, guided by the theory of TCM. They are available in different dosage forms, such as pill, tablet, capsule, granule, or injection. The use of CPMs is guided by syndrome differentiation and overall analysis of signs and symptoms. Provinces of China have prepared therapeutic schedules for the treatment of COVID-19 based on actual conditions (see Table 1 ). Many guidelines and expert consensus in China have recommended using CPMs to treat COVID-19. In this article, we identify the top 10 recommended CPMs to treat COVID-19 ( Figure 1 ). The list of CPMs includes Huoxiang Zhengqi capsule (HXZQC), Lianhua Qingwen capsule (LHQWC), Jinhua Qinggan granule (JHQGG), Shufeng Jiedu capsule (SFJDC), Tanreqing injection (TRQI), Xiyanping injection (XYPI), Xuebijing injection (XBJI), Shenfu injection (SFI), Shengmai injection (SMI), and Angong Niuhuang pill (AGNHP). Information on the drugs include the recommended guidelines, drug ingredients, indications, pharmacological research, clinical research, usage and dosage, adverse reactions, and precautions.

The decoctions, CPMs, acupuncture, and other TCM treatments have been comprehensively used for treatment, mainly based on syndrome differentiation. Specific CPMs have been widely employed to treat COVID-19 with remarkable therapeutic effects (National Health Commission of the People’s Republic of China and National Administration of Traditional Chinese Medicine, 2020).

CPMs are approved by the National Drug Regulatory Authority of China and processed according to prescribed methods using Chinese herbal medicines as raw materials, guided by the theory of TCM. They are available in different dosage forms, such as pill, tablet, capsule, granule, or injection. The use of CPMs is guided by syndrome differentiation and overall analysis of signs and symptoms. Provinces of China have prepared therapeutic schedules for the treatment of COVID-19 based on actual conditions (see Table 1 ). Many guidelines and expert consensus in China have recommended using CPMs to treat COVID-19. In this article, we identify the top 10 recommended CPMs to treat COVID-19 ( Figure 1 ). The list of CPMs includes Huoxiang Zhengqi capsule (HXZQC), Lianhua Qingwen capsule (LHQWC), Jinhua Qinggan granule (JHQGG), Shufeng Jiedu capsule (SFJDC), Tanreqing injection (TRQI), Xiyanping injection (XYPI), Xuebijing injection (XBJI), Shenfu injection (SFI), Shengmai injection (SMI), and Angong Niuhuang pill (AGNHP). Information on the drugs include the recommended guidelines, drug ingredients, indications, pharmacological research, clinical research, usage and dosage, adverse reactions, and precautions.

Antipyretic and analgesic – ACI intracerebral hemorrhage Neuroprotective effect (Han et al., 2019). Research by Zhonghua Liu et al. (Liu, 2009) revealed that HXZQC inhibited the lung index of mice infected with avian influenza virus (AIV) H5N1, reduced the development of lung disease, and enhanced the antiviral capacity of mice infected with AIV. The death rate of the infected mice was reduced through regulation of the gastrointestinal tract and strengthening of the stomach Qi. Hongkun Zhang (Zhang, 2013) found that HXZQC inhibited growth of Vibrio parahaemolyticus, Candida albicans, Staphylococcus aureus, and Streptococcus pneumoniae. Research by Wang et al. (2012) found that HXZQC inhibited lipopolysaccharide (LPS)-stimulated expression of proinflammatory cytokines by macrophages and inhibited epithelial barrier disorder induced by interferon-γ (IFN-γ), regulating immunity and improving gastroenteric function. Research by Chunyuan Li et al. (Li et al., 2017) showed that HXZQC significantly improved the thymus coefficient, spleen coefficient and immunoglobulin G (IgG) levels of mice with dampness obstructing spleen-stomach, and enhanced the immune function of the mice. Studies by Yinghui He et al. (He et al., 2006) and Shaobo Zong et al. (Zong et al., 2015) discovered that HXZQC had therapeutic effects in mice with Bacillus dysenteriae and Salmonella typhimurium-induced diarrhea (BSD mice), mice with bacterial enteritis, and model rats with diarrhea-predominant irritable bowel syndrome (IBS). Clinical symptoms were significantly improved, which might be due to effects on the balance of CD4+ and CD8+ T lymphocytes, and reduction of interleukin-2 (IL-2), interleukin-10 (IL-10), interleukin-1β (IL-1β), and tumor necrosis factor alpha (TNF-α) levels. The results suggested that HXZQC, via immune-regulation and anti-inflammatory activity, could have therapeutic effects against many gastrointestinal disorders. Research by Hefei Huang et al. (Huang et al., 2016) showed that HXZQC extracts had a positive regulatory effect on intestinal dysfunction, and had therapeutic efficacy in model rats with diarrhea-predominant IBS. Efficacy was mediated by improving serum NO levels and reducing the concentrations of 5-hydroxytryptamine (5-HT), plasma motilin, and colonic somatostatin.
Clinical Research on HXZQC
Modern clinical studies have shown that HXZQC has therapeutic effects against viral diseases, such as gastrointestinal-type cold, influenza, upper respiratory infection (URI), and viral enteritis (see Table 3 ). The Diagnosis and Treatment Scheme of Severe Acute Respiratory Syndrome (SARS) (Version 2004) (Chinese Medical Association and China Association of Chinese Medicine, 2004) recommended that HXZQC could be used for advanced stage pulmonary closure.
Research by Shuping Ma et al. showed that, compared with the control group (Ribavirin, interferon), HXZQC + Western medicines (Ribavirin, interferon) had a significant effect on antidiarrheal time and shortened the total time course in the treatment of children with rotavirus enteritis (p < 0.05) (Ma and Wang, 2012). Xiaoping Han et al. (Han, 2016) randomized 78 influenza patients into control and observation groups. Patients in the control group were given oral oseltamivir phosphate, while patients in the observation group received HXZQC in addition to oseltamivir phosphate. Compared with those in the control group, patients in the observation group had faster relief of fever symptoms, muscle aches, and fatigue (p < 0.05). The total response rate in the observation group was 97.44%, which was higher than the 82.05% of the control group (p < 0.05). The results showed that HXZQC enhanced the efficacy of oseltamivir phosphate in the treatment of influenza. Xingzhou Wu (Wu, 2010) randomized 90 cold dampness patients into two groups: the treatment group received HXZQP, while the control group received Ribavirin injection + Compound paracetamol and amantadine hydrochloride capsules. The total response rate in the treatment group was 88.9% compared to 77.1% in the control group (p < 0.05). Patients in the treatment group exhibited greater improvements in aversion to cold, fever, nasal congestion, running nose, spontaneous sweating, headache, cough and spitting, fatigue and weakness, body ache, and other cold symptoms compared to the control group. Hongjie Zhao et al. studied the efficacy and safety of HXZQC in the treatment of gastrointestinal-type cold by systematic evaluation. A total of 680 patients in eight randomized controlled trials (RCTs) were included in the research, and the results showed that the group receiving HXZQC had a significantly better clinical response than the group using Western medicines alone. The effects of HXZQC were superior to Western medicines in improving single symptoms (such as aversion to cold, fever, bowel sound and diarrhea) (Zhao et al., 2017). Dandan Yu et al. conducted a meta-analysis of 44 studies, including a total of 4,153 patients with acute gastroenteritis. The results showed that treatment with HXZQP + conventional therapy or norfloxacin tablets was superior to a single Western medicine in terms of total response rate and improvement of clinical symptoms (Yu et al., 2019).
Usage and Dosage of HXZQC
Oral administration, four capsules, twice a day.
Adverse Reactions of HXZQC
Potential drug eruption, purpura, shock, asthma, intestinal obstruction, upper gastrointestinal hemorrhage, hypoglycemia of childhood, infantile convulsions.
HXZQC Precautions
1) Nourishing traditional Chinese medicines should not be taken during the period of medication. 2) It is advisable that patients are on a light diet during the period of medication.

The death rate of the infected mice was reduced through regulation of the gastrointestinal tract and strengthening of the stomach Qi. Hongkun Zhang (Zhang, 2013) found that HXZQC inhibited growth of Vibrio parahaemolyticus, Candida albicans, Staphylococcus aureus, and Streptococcus pneumoniae. Research by Wang et al. (2012) found that HXZQC inhibited lipopolysaccharide (LPS)-stimulated expression of proinflammatory cytokines by macrophages and inhibited epithelial barrier disorder induced by interferon-γ (IFN-γ), regulating immunity and improving gastroenteric function. Research by Chunyuan Li et al. (Li et al., 2017) showed that HXZQC significantly improved the thymus coefficient, spleen coefficient and immunoglobulin G (IgG) levels of mice with dampness obstructing spleen-stomach, and enhanced the immune function of the mice. Studies by Yinghui He et al. (He et al., 2006) and Shaobo Zong et al. (Zong et al., 2015) discovered that HXZQC had therapeutic effects in mice with Bacillus dysenteriae and Salmonella typhimurium-induced diarrhea (BSD mice), mice with bacterial enteritis, and model rats with diarrhea-predominant irritable bowel syndrome (IBS). Clinical symptoms were significantly improved, which might be due to effects on the balance of CD4+ and CD8+ T lymphocytes, and reduction of interleukin-2 (IL-2), interleukin-10 (IL-10), interleukin-1β (IL-1β), and tumor necrosis factor alpha (TNF-α) levels. The results suggested that HXZQC, via immune-regulation and anti-inflammatory activity, could have therapeutic effects against many gastrointestinal disorders. Research by Hefei Huang et al. (Huang et al., 2016) showed that HXZQC extracts had a positive regulatory effect on intestinal dysfunction, and had therapeutic efficacy in model rats with diarrhea-predominant IBS. Efficacy was mediated by improving serum NO levels and reducing the concentrations of 5-hydroxytryptamine (5-HT), plasma motilin, and colonic somatostatin.

Research by Zhonghua Liu et al. (Liu, 2009) revealed that HXZQC inhibited the lung index of mice infected with avian influenza virus (AIV) H5N1, reduced the development of lung disease, and enhanced the antiviral capacity of mice infected with AIV. The death rate of the infected mice was reduced through regulation of the gastrointestinal tract and strengthening of the stomach Qi. Hongkun Zhang (Zhang, 2013) found that HXZQC inhibited growth of Vibrio parahaemolyticus, Candida albicans, Staphylococcus aureus, and Streptococcus pneumoniae. Research by Wang et al. (2012) found that HXZQC inhibited lipopolysaccharide (LPS)-stimulated expression of proinflammatory cytokines by macrophages and inhibited epithelial barrier disorder induced by interferon-γ (IFN-γ), regulating immunity and improving gastroenteric function. Research by Chunyuan Li et al. (Li et al., 2017) showed that HXZQC significantly improved the thymus coefficient, spleen coefficient and immunoglobulin G (IgG) levels of mice with dampness obstructing spleen-stomach, and enhanced the immune function of the mice. Studies by Yinghui He et al. (He et al., 2006) and Shaobo Zong et al. (Zong et al., 2015) discovered that HXZQC had therapeutic effects in mice with Bacillus dysenteriae and Salmonella typhimurium-induced diarrhea (BSD mice), mice with bacterial enteritis, and model rats with diarrhea-predominant irritable bowel syndrome (IBS). Clinical symptoms were significantly improved, which might be due to effects on the balance of CD4+ and CD8+ T lymphocytes, and reduction of interleukin-2 (IL-2), interleukin-10 (IL-10), interleukin-1β (IL-1β), and tumor necrosis factor alpha (TNF-α) levels. The results suggested that HXZQC, via immune-regulation and anti-inflammatory activity, could have therapeutic effects against many gastrointestinal disorders. Research by Hefei Huang et al. (Huang et al., 2016) showed that HXZQC extracts had a positive regulatory effect on intestinal dysfunction, and had therapeutic efficacy in model rats with diarrhea-predominant IBS. Efficacy was mediated by improving serum NO levels and reducing the concentrations of 5-hydroxytryptamine (5-HT), plasma motilin, and colonic somatostatin.

Clinical Research on HXZQC
Modern clinical studies have shown that HXZQC has therapeutic effects against viral diseases, such as gastrointestinal-type cold, influenza, upper respiratory infection (URI), and viral enteritis (see Table 3 ). The Diagnosis and Treatment Scheme of Severe Acute Respiratory Syndrome (SARS) (Version 2004) (Chinese Medical Association and China Association of Chinese Medicine, 2004) recommended that HXZQC could be used for advanced stage pulmonary closure.
Research by Shuping Ma et al. showed that, compared with the control group (Ribavirin, interferon), HXZQC + Western medicines (Ribavirin, interferon) had a significant effect on antidiarrheal time and shortened the total time course in the treatment of children with rotavirus enteritis (p < 0.05) (Ma and Wang, 2012). Xiaoping Han et al. (Han, 2016) randomized 78 influenza patients into control and observation groups. Patients in the control group were given oral oseltamivir phosphate, while patients in the observation group received HXZQC in addition to oseltamivir phosphate. Compared with those in the control group, patients in the observation group had faster relief of fever symptoms, muscle aches, and fatigue (p < 0.05). The total response rate in the observation group was 97.44%, which was higher than the 82.05% of the control group (p < 0.05). The results showed that HXZQC enhanced the efficacy of oseltamivir phosphate in the treatment of influenza. Xingzhou Wu (Wu, 2010) randomized 90 cold dampness patients into two groups: the treatment group received HXZQP, while the control group received Ribavirin injection + Compound paracetamol and amantadine hydrochloride capsules. The total response rate in the treatment group was 88.9% compared to 77.1% in the control group (p < 0.05). Patients in the treatment group exhibited greater improvements in aversion to cold, fever, nasal congestion, running nose, spontaneous sweating, headache, cough and spitting, fatigue and weakness, body ache, and other cold symptoms compared to the control group. Hongjie Zhao et al. studied the efficacy and safety of HXZQC in the treatment of gastrointestinal-type cold by systematic evaluation. A total of 680 patients in eight randomized controlled trials (RCTs) were included in the research, and the results showed that the group receiving HXZQC had a significantly better clinical response than the group using Western medicines alone. The effects of HXZQC were superior to Western medicines in improving single symptoms (such as aversion to cold, fever, bowel sound and diarrhea) (Zhao et al., 2017). Dandan Yu et al. conducted a meta-analysis of 44 studies, including a total of 4,153 patients with acute gastroenteritis. The results showed that treatment with HXZQP + conventional therapy or norfloxacin tablets was superior to a single Western medicine in terms of total response rate and improvement of clinical symptoms (Yu et al., 2019).

Relevant Information on the Clinical Application of LHQWC
Recommended Therapeutic Regimens
LHQWC has been recommended in 19 therapeutic regimens for treatment of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of LHQWC
Forsythia suspensa (Thunb.) Vahl (Lianqiao), Lonicera japonica Thunb. (Jinyinhua), Ephedra equisetina Bunge (Zhimahuang), Prunus armeniaca L. (Chaoxingren), Gypsum fibrosum (Shigao), Isatis tinctoria L. (Banlangen), Dryopteris crassirhizoma Nakai (Guanzhong), Houttuynia cordata Thunb. (Yuxingcao), Pogostemon cablin (Blanco) Benth. (Guanghuoxiang), Rheum palmatum L. (Dahuang), Rhodiola rosea L. (Hongjingtian), Mentholum (Bohenao), and Glycyrrhiza uralensis Fisch. ex DC. (Gancao). Basic information on LHQWC is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With LHQWC
LHQWC is used during the clinical observation period of COVID-19, and wind-heat invading lung in early stage of the disease (mild case). The indicative symptoms are fever, mild aversion to cold, cough, weakness, headache and body pain, sore throat, and constipation.
Progress of Pharmacological Research on LHQWC
Modern pharmacological studies have shown that LHQWC has antiviral, immune-regulatory, anti-inflammatory, and antioxidant properties, efficacy against lung injury, and other effects (see Table 3 ).
LHQWC significantly inhibited SARS-CoV-2 replication in Vero E6 cells and markedly reduced the production of pro-inflammatory cytokines (TNF-α, IL-6, CCL-2/MCP-1, and CXCL-10/IP-10) at the mRNA level. Furthermore, LHQWC treatment resulted in abnormal virion particle morphology in cells. LHQWC significantly inhibits SARS-CoV-2 replication, affects virus morphology and exerts anti-inflammatory activity in vitro (Li R. F. et al., 2020).
In vitro experiments have shown significant antiviral activity against SARS-CoV, AIV H7N9, dual H1N1/H3N2, together with inhibition of Middle East Respiratory Syndrome (MERS)-CoV activity to a certain degree (Yao et al., 2020). Yuewen Ding et al. used MTT and plaque reduction assays to show that LHQWC inhibited proliferation of multiple strains of influenza virus, and reduced virus titer and levels of inflammatory cytokines in the lungs of infected mice. The results indicated that LHQWC acted as a broad-spectrum antiviral and, in particular, regulated the immune response to viral infection (Ding et al., 2017). Qi Li et al. discovered that LHQWC not only reversed LPS-stimulated expression of macrophage chemotactic factor-1 (MCP-1) by macrophages, but also significantly improved pulmonary edema in a mouse model of acute lung injury. Inhibition of expression and secretion of MCP-1 in lung tissues of model mice was accompanied by reduced infiltration of mononuclear macrophages and reduction of inflammatory injury (Li et al., 2019). Fen Ping et al. studied the effects of LHQWC on rats with oxidative lung injury caused by fine particulate matters (PM 2.5). The results showed that LHQWC significantly reduced lactate dehydrogenase (LDH) and malondialdehyde (MDA) serum levels in rats with lung injury, increased levels of glutathione peroxidase (GSH-Px), reduced pathological damage of lung tissues, and inhibited exudation of inflammatory cells into the alveolar cavity. Together, the data indicated that LHQWC protected against oxidative stress injury in the lungs of rats (Ping et al., 2016). Wenwen Cui et al. studied the impact of LHQWC in a mouse model of acute lung injury caused by intratracheal infusion of LPS. LHQWC alleviated the inflammatory response in lung tissues by downregulating the IKK/IκB/nuclear factor (NF)-κB signaling pathway, thus, protecting mice from acute lung injury (Cui et al., 2016). Siwen Tang et al. studied the effects of LHQWC intervention on pathological lung tissue injury in mice and expression of inflammatory cytokines caused by exposure to automobile exhaust. The results showed that LHQWC reduced protein and mRNA expression of inflammatory cytokines in lung tissue by reducing blood levels of inflammatory cytokines, thus, protecting against lung tissue injury caused by automobile exhaust (Tang et al., 2015).
Clinical Research on LHQWC
Modern clinical studies have shown that LHQWC has therapeutic effects against viral diseases, such as COVID-19, SARS, MERS, influenza, and human infection with H7N9 avian influenza. It can also be used to treat URI, chronic obstructive pulmonary disease (COPD) and other conditions (see Table 3 ). LHQWC has been recommended in diagnosis and treatment schemes such as China’s SARS Diagnosis and Treatment Scheme (Version 2004) (Chinese Medical Association and China Association of Chinese Medicine, 2004), MERS Diagnosis and Treatment Scheme (Version 2015) (National Health and Family Planning Commission of People’s Republic of China, 2015), China’s Influenza Diagnosis and Treatment Scheme (Version 2019) (National Health Commission of the People's Republic of China and National Administration of Traditional Chinese Medicine, 2019), and Diagnosis and Treatment Scheme for Human Infection with H7N9 Avian Influenza (Version 1, 2017) (National Health and Family Planning Commission of People's Republic of China, 2017).
Ke Hu et al. conducted a prospective multicenter open-label randomized controlled trial on LHQWC capsule in confirmed cases of COVID-19. Patients (284) were randomized to receive usual treatment alone or in combination with LHQWC capsules (four capsules, thrice daily) for 14 days. The primary endpoint was the rate of symptom (fever, fatigue, coughing) recovery. The recovery rate was significantly higher in the combined treatment group compared with the control group (91.5% vs. 82.4%, p = 0.022). The median time to symptom recovery was markedly shorter in the combined treatment group (median: 7 vs. 10 days, p < 0.001). Time to recovery of fever (2 vs. 3 days), fatigue (3 vs. 6 days) and coughing (7 vs. 10 days) was also significantly shorter in the combined treatment group (all p < 0.001). The rate of improvement in chest computed tomographic manifestations (83.8% vs. 64.1%, p < 0.001) and clinical cure (78.9% vs. 66.2%, p = 0.017) were also higher in the combined treatment group. However, the two groups did not differ in the rate of conversion to severe cases or viral assay findings (p > 0.05). No serious adverse events were reported (Hu et al., 2020).
Ruibing Lyu et al. conducted clinical research on 63 patients receiving conventional therapy in combination with LHQWC (treatment group) and 38 patients receiving only conventional therapy (control group). Clinical data were collected 10 days after the treatment. A comparison between the two groups was performed in terms of disappearance rates of cardinal symptoms (fever, cough, and weakness), duration of fever and disappearance rates of other individual symptoms and signs. The disappearance rates of fever, cough, and weakness in the treatment group were 86.7%, 55.6%, and 82.5%, respectively, which were higher than those in the control group (67.7%, 30.6%, and 58.6%; p < 0.05). The median duration of fever was 6 days in patients in the treatment group and 7 days in the control group. There was no statistically significant difference between the groups (p = 0.171). The disappearance rates of short breath and moist crackles (68.2% and 56.0%) were higher than those in the control group (20.0% and 20.0%, p < 0.05). There were four cases of aggravation in the treatment group (6.4%) and six cases in the control group (15.8%), with no statistically significant difference (p > 0.05). There were no obvious adverse reactions in the treatment group (Lyu et al., 2020).
Dezhong Cheng et al. conducted a multi-center retrospective analysis of the therapeutic effect of LHQWC in 51 COVID-19 patients. The control group was treated with simple nutritional support, symptomatic treatment, antiviral therapy and antimicrobial therapy. The treatment group was combined with LHQWC (6 g/bag) on the basis of the control group, one bag each time, 3 times a day. The clinical data of patients treated for 7 days were collected. The results showed that combined application of LHQWC significantly improved fever, weakness, cough, shortness of breath, chest distress, anorexia, and other clinical symptoms of COVID-19. Improvements of the main symptoms and reduced incidence of the severe form suggested that LHQWC could be effective in the treatment of patients with COVID-19 (Cheng et al., 2020).
Ping Yu et al. conducted a study on the therapeutic effect of LHQWC combined with Abidole in the treatment of mild COVID-19. A total of 295 patients were randomly divided into two groups. The control group (n = 148) was treated with Abidole (0.2 g per day) orally, and the observation group (n = 147) was treated with LHQWC (6 g, thrice daily) combined with Abidole. The results showed that the total effective rate of the observation group was significantly higher than that of the control group (80.95% vs 64.86%), and the rate of severe illness was significantly lower than that of the control group (14.29% vs 23.65%). After 7 days of treatment, the scores for the main TCM syndromes (fever, fatigue, cough, dry throat, chest tightness) and the levels of C-reactive protein (CRP) and procalcitonin (PCT) in the observation group were significantly lower than those in the control group (p < 0.05), while white blood cells (WBC) and lymphocyte (LYM) were significantly higher than those in the control group. The effective rate of chest computerized tomography (CT) in the observation group was 69.39%, which was higher than that in the control group (62.84%), but the difference was not statistically significant (p > 0.05). There were no serious drug-related adverse reactions in either group. The results show that LHQWC combined with Abidole can effectively relieve clinical symptoms in patients with mild COVID-19, regulate the expression of related inflammatory factors, improve the curative effect and reduce the rate of severe illness (Yu P. et al., 2020).
Lili Liu et al. conducted a retrospective analysis of the therapeutic effect of LHQWC in 32 COVID-19 patients. The patients were divided into two groups: Group A + L, in which 18 patients received Abidole (0.2 g, thrice daily) combined with LHQWC; and Group L, in which 14 patients received LHQWC alone. During treatment there was one critical case in each group. Abnormal liver function was observed in 14 cases (77.78%) in Group A + L and 8 cases (57.14%) in Group L. Antibiotic treatment was applied in 17 cases (94.44%) in Group A + L and 13 cases (92.86%) in Group L. Glucocorticoid use was reported in 10 cases (55.56%) in Group A + L and 9 cases (64.29%) in Group L. Compared with Group L, significantly faster recovery of temperature (t = −2.471, p = 0.019), recovery of respiratory symptoms (t = −2.918, p = 0.007), chest CT inflammation absorption (t = −2.937, p = 0.006), time until two consecutive negative virus nucleic acid tests (t = −2.930, p = 0.006), and shorter hospital stay (t = −2.785, p = 0.009) were observed in Group A + L. Abidor combined with LHQWC can be used to treat COVID-19, with good tolerance, to shorten the course of treatment (Liu et al., 2020).
Zhongping Duan et al. conducted a random, double-blind, and positive-drug parallel control clinical trial on the efficiency and safety of LHQWC against H1N1. It was found that LHQWC reduced disease severity and the duration of symptoms. The drug was also well tolerated, indicating that LHQWC might become an alternative therapeutic measure against H1N1 viral infection (Duan et al., 2011). Pan Zhao et al. found by meta-analysis that LHQWC improved cough, sore throat, body ache, and other symptoms of patients infected with H1N1 virus, reduced the duration of fever, and was more effective than oseltamivir (Zhao P. et al., 2014). Shiheng Wang et al. conducted a systematic review of the literature on efficacy and safety of LHQWC in treating viral flu. The results showed that LHQWC gave a better total response rate, symptom improvement rate and body temperature recovery rate than the control group in treating viral flu, but consideration of its safety was important (Wang et al., 2019). Li Tiehui et al. compared the clinical therapeutic effect of LHQWC and vitamin C Yinqiao Tablets in patients with URI, and found that LHQWC significantly improved nasal congestion, fever, headache, sore throat, weakness, aches in the limbs, intolerance of cold, and other clinical symptoms. LHQWC had high efficacy and safety, and was therefore worthy of promotion (Li, 2019). Dong Liang et al. conducted clinical research on 100 patients with COPD, and discovered that LHQWC improved conditions in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), especially those in the high risk subgroup. The mode of action might be related to its ability to reduce release of inflammatory mediators (Dong et al., 2014).
Usage and Dosage of LHQWC:
Oral administration, four capsules, 3 times a day.
Adverse Reactions of LHQWC
Possible nausea, vomiting, diarrhea, stomach discomfort, heartburn, poor appetite, and other gastrointestinal adverse reactions; there might be abnormal liver function, palpitations or rash, and other side effects occasionally.
LHQWC Precautions
1) Pregnant and lactating women should use with caution. 2) It contains ephedrae herba (Mahuang), so should be used with caution by athletes and patients with high blood pressure and heart disease. 3) Those with previous history of liver disease or with abnormal liver function should use with caution. 4) It contains rheum, so the dose should be reduced appropriate in subjects who experience increased stool frequency and shapeless stools after administration. 5) Nourishing traditional Chinese medicine should not be taken at the same time.

Modern clinical studies have shown that LHQWC has therapeutic effects against viral diseases, such as COVID-19, SARS, MERS, influenza, and human infection with H7N9 avian influenza. It can also be used to treat URI, chronic obstructive pulmonary disease (COPD) and other conditions (see Table 3 ). LHQWC has been recommended in diagnosis and treatment schemes such as China’s SARS Diagnosis and Treatment Scheme (Version 2004) (Chinese Medical Association and China Association of Chinese Medicine, 2004), MERS Diagnosis and Treatment Scheme (Version 2015) (National Health and Family Planning Commission of People’s Republic of China, 2015), China’s Influenza Diagnosis and Treatment Scheme (Version 2019) (National Health Commission of the People's Republic of China and National Administration of Traditional Chinese Medicine, 2019), and Diagnosis and Treatment Scheme for Human Infection with H7N9 Avian Influenza (Version 1, 2017) (National Health and Family Planning Commission of People's Republic of China, 2017).
Ke Hu et al. conducted a prospective multicenter open-label randomized controlled trial on LHQWC capsule in confirmed cases of COVID-19. Patients (284) were randomized to receive usual treatment alone or in combination with LHQWC capsules (four capsules, thrice daily) for 14 days. The primary endpoint was the rate of symptom (fever, fatigue, coughing) recovery. The recovery rate was significantly higher in the combined treatment group compared with the control group (91.5% vs. 82.4%, p = 0.022). The median time to symptom recovery was markedly shorter in the combined treatment group (median: 7 vs. 10 days, p < 0.001). Time to recovery of fever (2 vs. 3 days), fatigue (3 vs. 6 days) and coughing (7 vs. 10 days) was also significantly shorter in the combined treatment group (all p < 0.001). The rate of improvement in chest computed tomographic manifestations (83.8% vs. 64.1%, p < 0.001) and clinical cure (78.9% vs. 66.2%, p = 0.017) were also higher in the combined treatment group. However, the two groups did not differ in the rate of conversion to severe cases or viral assay findings (p > 0.05). No serious adverse events were reported (Hu et al., 2020).
Ruibing Lyu et al. conducted clinical research on 63 patients receiving conventional therapy in combination with LHQWC (treatment group) and 38 patients receiving only conventional therapy (control group). Clinical data were collected 10 days after the treatment. A comparison between the two groups was performed in terms of disappearance rates of cardinal symptoms (fever, cough, and weakness), duration of fever and disappearance rates of other individual symptoms and signs. The disappearance rates of fever, cough, and weakness in the treatment group were 86.7%, 55.6%, and 82.5%, respectively, which were higher than those in the control group (67.7%, 30.6%, and 58.6%; p < 0.05). The median duration of fever was 6 days in patients in the treatment group and 7 days in the control group. There was no statistically significant difference between the groups (p = 0.171). The disappearance rates of short breath and moist crackles (68.2% and 56.0%) were higher than those in the control group (20.0% and 20.0%, p < 0.05). There were four cases of aggravation in the treatment group (6.4%) and six cases in the control group (15.8%), with no statistically significant difference (p > 0.05). There were no obvious adverse reactions in the treatment group (Lyu et al., 2020).
Dezhong Cheng et al. conducted a multi-center retrospective analysis of the therapeutic effect of LHQWC in 51 COVID-19 patients. The control group was treated with simple nutritional support, symptomatic treatment, antiviral therapy and antimicrobial therapy. The treatment group was combined with LHQWC (6 g/bag) on the basis of the control group, one bag each time, 3 times a day. The clinical data of patients treated for 7 days were collected. The results showed that combined application of LHQWC significantly improved fever, weakness, cough, shortness of breath, chest distress, anorexia, and other clinical symptoms of COVID-19. Improvements of the main symptoms and reduced incidence of the severe form suggested that LHQWC could be effective in the treatment of patients with COVID-19 (Cheng et al., 2020).
Ping Yu et al. conducted a study on the therapeutic effect of LHQWC combined with Abidole in the treatment of mild COVID-19. A total of 295 patients were randomly divided into two groups. The control group (n = 148) was treated with Abidole (0.2 g per day) orally, and the observation group (n = 147) was treated with LHQWC (6 g, thrice daily) combined with Abidole. The results showed that the total effective rate of the observation group was significantly higher than that of the control group (80.95% vs 64.86%), and the rate of severe illness was significantly lower than that of the control group (14.29% vs 23.65%). After 7 days of treatment, the scores for the main TCM syndromes (fever, fatigue, cough, dry throat, chest tightness) and the levels of C-reactive protein (CRP) and procalcitonin (PCT) in the observation group were significantly lower than those in the control group (p < 0.05), while white blood cells (WBC) and lymphocyte (LYM) were significantly higher than those in the control group. The effective rate of chest computerized tomography (CT) in the observation group was 69.39%, which was higher than that in the control group (62.84%), but the difference was not statistically significant (p > 0.05). There were no serious drug-related adverse reactions in either group. The results show that LHQWC combined with Abidole can effectively relieve clinical symptoms in patients with mild COVID-19, regulate the expression of related inflammatory factors, improve the curative effect and reduce the rate of severe illness (Yu P. et al., 2020).
Lili Liu et al. conducted a retrospective analysis of the therapeutic effect of LHQWC in 32 COVID-19 patients. The patients were divided into two groups: Group A + L, in which 18 patients received Abidole (0.2 g, thrice daily) combined with LHQWC; and Group L, in which 14 patients received LHQWC alone. During treatment there was one critical case in each group. Abnormal liver function was observed in 14 cases (77.78%) in Group A + L and 8 cases (57.14%) in Group L. Antibiotic treatment was applied in 17 cases (94.44%) in Group A + L and 13 cases (92.86%) in Group L. Glucocorticoid use was reported in 10 cases (55.56%) in Group A + L and 9 cases (64.29%) in Group L. Compared with Group L, significantly faster recovery of temperature (t = −2.471, p = 0.019), recovery of respiratory symptoms (t = −2.918, p = 0.007), chest CT inflammation absorption (t = −2.937, p = 0.006), time until two consecutive negative virus nucleic acid tests (t = −2.930, p = 0.006), and shorter hospital stay (t = −2.785, p = 0.009) were observed in Group A + L. Abidor combined with LHQWC can be used to treat COVID-19, with good tolerance, to shorten the course of treatment (Liu et al., 2020).
Zhongping Duan et al. conducted a random, double-blind, and positive-drug parallel control clinical trial on the efficiency and safety of LHQWC against H1N1. It was found that LHQWC reduced disease severity and the duration of symptoms. The drug was also well tolerated, indicating that LHQWC might become an alternative therapeutic measure against H1N1 viral infection (Duan et al., 2011). Pan Zhao et al. found by meta-analysis that LHQWC improved cough, sore throat, body ache, and other symptoms of patients infected with H1N1 virus, reduced the duration of fever, and was more effective than oseltamivir (Zhao P. et al., 2014). Shiheng Wang et al. conducted a systematic review of the literature on efficacy and safety of LHQWC in treating viral flu. The results showed that LHQWC gave a better total response rate, symptom improvement rate and body temperature recovery rate than the control group in treating viral flu, but consideration of its safety was important (Wang et al., 2019). Li Tiehui et al. compared the clinical therapeutic effect of LHQWC and vitamin C Yinqiao Tablets in patients with URI, and found that LHQWC significantly improved nasal congestion, fever, headache, sore throat, weakness, aches in the limbs, intolerance of cold, and other clinical symptoms. LHQWC had high efficacy and safety, and was therefore worthy of promotion (Li, 2019). Dong Liang et al. conducted clinical research on 100 patients with COPD, and discovered that LHQWC improved conditions in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD), especially those in the high risk subgroup. The mode of action might be related to its ability to reduce release of inflammatory mediators (Dong et al., 2014).

Relevant Information on the Clinical Application of JHQGG
Recommended Therapeutic Regimens
JHQGG has been recommended in 13 therapeutic regimens of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of JHQGG
Forsythia suspensa (Thunb.) Vahl (Lianqiao), Lonicera japonica Thunb. (Jinyinhua), Ephedra equisetina Bunge (Zhimahuang), Prunus armeniaca L. (Chaoxingren), Gypsum Fibrosum (Shigao), Scutellaria baicalensis Georgi (Huangqin), Fritillaria thunbergii Miq. (Zhebeimu), Anemarrhena asphodeloides Bunge (Zhimu), Arctium lappa L. (Niubangzi), Artemisia annua L. (Qinghao), Mentha canadensis L. (Bohe), and Glycyrrhiza uralensis Fisch. ex DC. (Gancao). Basic information on JHQGG is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With JHQGG
JHQGG is used to treat the syndrome of wind-heat invading lung during the clinical observation period of COVID-19 and the early stage of the disease (mild case). Indicative symptoms are fever, mild aversion to cold, weakness, cough, headache and body pain, and sore throat.
Progress of Pharmacological Research on JHQGG
Modern pharmacological studies have found that JHQGG has antiviral, immune-regulatory, and anti-inflammatory effects (see Table 3 ).
Jianping Qi et al. showed that JHQGG significantly decreased the average levels of C-reactive protein (CRP) and IFN-γ in serum of influenza patients. Patients exhibited decreased inflammatory response and improved immune function after treatment, which might be due to the antiviral activity of the main ingredients, such as Lonicerae japonicae flos, Scutellariae radix, Forsythiae fructus, and Artemisiae annuae herba (Qi et al., 2016).
Clinical Research on JHQGG
Modern clinical studies have shown that JHQGG has therapeutic efficacy against viral diseases (see Table 3 ). JHQGG has been recommended in China’s Influenza Diagnosis and Treatment Scheme (Version 2019).
COVID-19 outpatients (123) were randomly divided into a treatment group (JHQGG two bags per time, 3 times a day, combined with routine treatment for 5 days, n = 82) and a control group (only routine treatment, n = 41). The addition of JHQGG significantly alleviated fever, cough, fatigue, sputum and anxiety, and the hospitalization rate tended to be lower than in the control group (Duan et al., 2020). In treatment of H1N1, use of JHQGG alone or in combination with oseltamivir effectively shortened fever duration. The duration of fever in patients treated with oseltamivir in combination with JHQGG was significantly shorter (19%) than in those treated with oseltamivir alone, suggesting that JHQGG could serve as an alternative therapeutic measure against H1N1 (Wang C. et al., 2011). Jianping Qi observed 174 cases of influenza patients and found that JHQGG significantly reduced serum levels of cytokines and improved immune function (Qi et al., 2016). A double-blind, randomized and controlled study on JHQGG in treating influenza syndrome of wind-heat invading lung by Guoqin Li et al. showed that it was effective and safe (Li et al., 2013).
Usage and Dosage of JHQGG
Taken after dissolving in boiled water, one bag, 3 times a day.
Adverse Reactions of JHQGG
Potential for nausea, vomiting, diarrhea, stomach discomfort, heartburn, poor appetite and other gastrointestinal adverse reactions; there might be abnormal liver function, palpitations, or rash occasionally.
JHQGG Precautions
1) Those with deficiency-cold in spleen and stomach should use with caution. 2) It contains ephedrae herba (Mahuang), so should be used with caution by athletes and patients with high blood pressure and heart disease. 3) Those with previous history of liver disease or with abnormal liver function should use with caution. 4) Nourishing traditional Chinese medicine should not be taken at the same time.

Relevant Information on the Clinical Application of SFJDC
Recommended Therapeutic Regimens
SFJDC has been recommended in 15 therapeutic regimens of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of SFJDC
Reynoutria japonica Houtt. (Huzhang), Forsythia suspensa (Thunb.) Vahl (Lianqiao), Isatis tinctoria L. (Banlangen), Bupleurum chinense DC. (Chaihu), Patrinia scabiosifolia Link (Baijiangcao), Verbena officinalis L. (Mabiancao), Phragmites australis (Cav.) Trin. ex Steud. (Lugen), and Glycyrrhiza uralensis Fisch. ex DC. (Gancao). Basic information on SFJDC is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With SFJDC
SFJDC is used to treat external wind-heat syndrome during the clinical observation period of COVID-19 and the early stage of the disease (mild case). Indicative symptoms are fever, aversion to cold, cough with yellow phlegm, weakness, and sore throat.
Progress of Pharmacological Research on SFJDC
Modern pharmacological studies have found that SFJDC has antiviral, antibacterial, and anti-inflammatory properties and protects against lung injury (see Table 3 ).
Yanyan Bao et al. evaluated the broad-spectrum antiviral activity of SFJDC by cytopathic effect (CPE) inhibition. A total of eight viruses, including H1N1, herpes simplex (HSV), respiratory syncytial virus, adenovirus (ADV) and Coxsackie virus, were evaluated. SFJDC had significant in vitro broad-spectrum antiviral activity and the best inhibitory effect was against parainfluenza virus (PIV). Similar results were obtained from in vivo experiments (Qiu et al., 2014; Bao et al., 2019). Ying Liu et al. used H1N1 FM1 and PR8 strains to induce nasal drip infection in an immunocompromised mouse pneumonia model. Therapeutic and preventive effects of SFJDC were observed against H1N1 infection in vivo. The results showed that SFJDC influenced the immune function of the mice, improved pneumonia symptoms caused by influenza virus, reduced the lung index of mice infected with H1N1, significantly reduced mortality, and had good therapeutic efficacy (Liu et al., 2010). Research by Weiwei Lv et al. found that SFJDC had inhibitory activity against multiple viruses and bacteria. Its antiviral activity was inferior to that of Ribavirin, but its cytotoxicity was lower. Both antiviral activity and antibacterial action were superior to those of Qingkailing granules (QKLG) (Lv et al., 2013). Li Ma et al. used a mouse pneumonia model induced by Streptococcus pneumoniae to study the anti-inflammatory mechanism of SFJDC. They discovered that it reduced white blood cell (WBC) count, reduced serum levels of the transcription factor nuclear factor kappa B (NF-κB), MCP-1, inflammatory mediator BK and COX-2, thus, having a therapeutic effect in the model (Ma et al., 2018). Further studies found that SFJDC had a significant immune regulatory function, reducing levels of B lymphocytes, CD8+ cells, interleukin-1α (IL-1α), IL-1β, IL-2, IgM, and IgG to improve lung function in mice with pneumonia. SFJDC increased the CD4+/CD8+ ratio and number of natural killer (NK) cells, thus, having a therapeutic effect in the pneumonia model (Ma et al., 2019a; Ma et al., 2019b). Zhengang Tao et al. observed a protective function of SFJDC against endotoxin LPS-induced rat lung injury. Their results showed that SFJDC inhibited the LPS-induced inflammatory response, and reduced LPS-induced lung injury. Its mechanism of action might be inhibition of the MAPK (mitogen-activated protein kinase)/NF-κB signaling pathway and downregulation of NF-κB mRNA expression (Tao et al., 2014). Yanmei Li et al. used a Pseudomonas aeruginosa (PAK)-induced KM mouse acute lung injury model to explore the mode of action of SFJDC in treatment of acute lung injury. They found that SFJDC significantly alleviated lung injury in the model and its mode of action might be related to the ERK signaling pathway (Li et al., 2017).
Clinical Research on SFJDC
SFJDC comes from “Detoxification Powder,” and is mainly used to treat fever, parotitis, amygdalitis, plague, and other diseases. Recent studies have shown that SFJDC has good clinical efficacy against viral diseases (such as MERS, influenza, human infection with H7N9 avian influenza) and respiratory diseases (such as acute URI, AECOPD, pneumonia, etc.) (see Table 3 ). SFJDC has been recommended in diagnosis and treatment schemes such as MERS Diagnosis and Treatment Scheme (Version 2015), China’s Influenza Diagnosis and Treatment Scheme (Version 2019), and Diagnosis and Treatment Scheme for Human Infection with H7N9 Avian Influenza (Version 1, 2017).
Lei Wang et al. conducted a retrospective analysis of 87 patients with acute URI + fever, and found that patients treated with SFJDC had a significantly higher total response rate than those in the control group. SFJDC effectively improved respiratory symptoms in patients with acute URI + fever (Wang and Qiu, 2018). In the treatment of community acquired pneumonia (CAP), application of SFJDC shortened recovery time, reduced the duration of fever and reduced the levels of procalcitonin (PCT), CRP, WBC, and other indicators, effectively shortening the course of treatment (Wang, 2016). Hongxia Yu et al. evaluated the impact of SFJDC on inflammation-associated cytokines in patients with AECOPD. The results showed that SFJDC significantly reduced the levels of interleukin-8 (IL-8), TNF-α, CRP, and PCT, and had significant therapeutic efficacy against AECOPD (Yu H. X. et al., 2020). Tiling Wang et al. added SFJDC treatment to conventional treatment in 60 mild and moderate AECOPD patients and compared with 60 patients receiving conventional treatment as the control group. After 1 week, the treatment group had significantly higher arterial blood gas PaO2 than the control group, without any adverse reactions (Wang, 2015). Research showed that treatment of bacterial acute bronchitis and pneumonia with a combination of antibacterial drugs and SFJDC significantly shortened recovery of body temperature, duration of cough and the course of treatment compared with antibacterial drug alone. Chunlan Wang et al. observed that combined use of SFJDC and antibiotics significantly improved body temperature, blood sugar, ALT (glutamate transaminase), AST (aspartate aminotransferase) and other indicators compared with the control group, and patients had a higher oxygen index than the control group. The results suggested that SFJDC had a significant protective function against lung injury, and the mechanism might be related to inhibition of inflammatory response by SFJDC (Wang et al., 2014).
Usage and Dosage of SFJDC
Oral administration, four capsules, 3 times a day.
Adverse Reactions of SFJDC
Occasional nausea.
SFJDC Precautions
(1) Use is forbidden in those with allergic constitution or who are allergic to the drug. (2) Use is forbidden in those with deficiency-cold in spleen and stomach.

Relevant Information on the Clinical Application of TRQI
Recommended Therapeutic Regimens
TRQI has been recommended in 12 therapeutic regimens of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of TRQI
Scutellaria baicalensis Georgi (Huangqin), Ursi fellis pulvis (Xiongdanfen), Forsythia suspensa (Thunb.) Vahl (Lianqiao), and Lonicera japonica Thunb. (Jinyinhua). Basic information on TRQI is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With TRQI
TRQI is used for syndromes of epidemic toxin lung closure and phlegm-heat lung obstruction in the progressive stage of COVID-19 (critical case). Indicative symptoms are fever, cough, cough with difficulty in expectoration, chest distress, and shortness of breath.
Progress of Pharmacological Research on TRQI
Modern pharmacological studies have shown that TRQI is effective against influenza virus, destroys bacterial biofilm, inhibits airway inflammation, and improves lung injury (see Table 3 ).
Research by Jinsu Zheng et al. discovered that TRQI improved pathological injury of lung tissues in mice infected with influenza virus, and had significant antiviral activity in influenza virus infected mice. The antiviral activity of TRQI might be due to its inhibition of cellular proliferation and enhancement of immunity (Zheng and Gu, 2009). Weifeng Yang et al. discovered that TRQI could destroy methicillin-resistant Staphylococcus aureus (MRSA) biofilm and induce its death. When combined with vancomycin or linezolid below the minimal inhibitory concentration (MIC) concentration, synergistic anti-biofilm activity was observed that was significantly higher than when using TRQI alone (Yang et al., 2018). Research by Yi Wang et al. showed that the efficacy of TRQI in the treatment of acute pneumonia was mediated by destruction of bacterial biofilm, which is different to the mechanism of penicillin (Wang Y. et al., 2011). Wei Liu et al. discovered that TRQI might treat airway mucus hypersecretion by regulating the interleukin-17 (IL-17) signaling pathway and its downstream protein MUC5AC. An in vivo experiment showed that TRQI could significantly inhibit excessive secretion of LPS-stimulated MUC5AC and expression of TNF-α, interleukin-6 (IL-6), IL-8, and IL-17A in terms of protein and mRNA levels (Liu W. et al., 2019). Animal experiments conducted by Wei Liu et al. showed that TRQI inhibited airway inflammation caused by LPS through the MAPK/NF-κB pathway, and showed a dose-dependent effect (Liu et al., 2016). Li Wen et al. found that TRQI improved signs and symptoms in AECOPD patients, which might be mediated by reduction of serum IL-8 and neutrophil elastase (NE) levels, and improved airway inflammation and mucus hypersecretion (Li et al., 2010). Research by Li Pengtao et al. discovered that TRQI improved blood flow in capillaries of the alveolar walls while repressing the LPS-induced inflammatory cascade, which was the pharmacological basis for its effective alleviation of acute lung injury and prevention of decreased arterial partial oxygen pressure (Li et al., 2005).
Clinical Research on TRQI
Modern clinical studies have shown that TRQI has therapeutic efficacy against infectious diseases, such as viral pneumonia, MERS, human infection with H7N9 avian influenza, acute bronchitis, acute attack of chronic bronchitis, CAP, tuberculosis accompanied by infection, and AECOPD (see Table 3 ). TRQI has been recommended in MERS Diagnosis and Treatment Scheme (Version 2015) and Diagnosis and Treatment Scheme for Human Infection with H7N9 Avian Influenza (Version 1, 2017).
A systematic evaluation of eight published randomized and controlled trials that included a total of 590 adult patients with viral pneumonia found that TRQI had advantages in terms of response rate, faster change of chest radiography, average length of stay, and other aspects (Pan, 2016). Research results from Jinzhi Liang et al. showed that there was no statistically significant difference in the clinical effect of combined TRQI and Ribavirin or TRQI alone in the treatment of hand-foot-and-mouth disease. Both treatments were superior to that of Ribavirin alone (Liang et al., 2013). Research by Wang Pei et al. showed that potential benefits of TRQI in the treatment of acute bronchitis included improved response rate, and reduced fever, cough, crackles, and X-ray shadow absorption (Wang et al., 2016). Research results of Lini Gao et al. showed that combined use of TRQI and Western medicines was more effective than Western medicines alone in the treatment of acute bronchitis and gave superior improvement of clinical symptoms (Gao et al., 2019). Hongli Jiang et al. showed by systematic evaluation that administration of TRQI to treat CAP on the basis of antibiotics and symptomatic treatment significantly improved clinical symptoms. Cough with expectoration was improved, the duration of fever was shortened and recovery of chest radiography and hemogram were promoted without significant adverse reactions (Jiang et al., 2009). Lian Xiong et al. showed by systematic evaluation that TRQI might have the same overall effect as some antibacterial drugs in treatment of patients with tuberculosis accompanied by lung infection, but improved efficacy was observed in combination with antibacterial drugs. This might be due to the bacteriostatic effects of TRQI and elimination of inflammatory mediators (Lian et al., 2018). A total of 14 trials and 954 patients were included in a study by Yunqing Zhong, and the results showed that combined use of TRQI and antibacterial drugs improved the clinical effects and lung function in AECOPD patients, reduced pCO2, and shortened the length of stay without serious adverse reactions (Zhong et al., 2010).
Usage and Dosage of TRQI
20 ml once for adults, 40 ml once for severe patients, with addition of 250–500 ml 5% glucose or 0.9% sodium chloride; intravenous drip at less than 60 drops per min, once a day.
Adverse Reactions of TRQI
1) Some patients may have dizziness, chest distress, nausea, vomiting, and diarrhea. 2) Flushing, rash or itching and other allergic reactions occasionally. 3) Rarely, palpitations, chill and difficulty breathing. 4) Extremely rarely, allergic shock. 5) Other adverse reactions: dry mouth, fever, periorbital facial edema, discomfort at infusion site.
TRQI Precautions
1) Use is forbidden in those with liver and renal failure; 2) Use is forbidden in those with severe lung and heart disease accompanied by heart failure; 3) Use is forbidden in pregnant women and infants less than 24 months; 4) It should be used alone and must not be mixed with other drugs; 5) Dilution ratio of the liquid shall be no lower than 1:10 (liquid: solvent) and the diluted liquid must be used within 4 h.

Animal experiments conducted by Wei Liu et al. showed that TRQI inhibited airway inflammation caused by LPS through the MAPK/NF-κB pathway, and showed a dose-dependent effect (Liu et al., 2016). Li Wen et al. found that TRQI improved signs and symptoms in AECOPD patients, which might be mediated by reduction of serum IL-8 and neutrophil elastase (NE) levels, and improved airway inflammation and mucus hypersecretion (Li et al., 2010). Research by Li Pengtao et al. discovered that TRQI improved blood flow in capillaries of the alveolar walls while repressing the LPS-induced inflammatory cascade, which was the pharmacological basis for its effective alleviation of acute lung injury and prevention of decreased arterial partial oxygen pressure (Li et al., 2005).

Research by Jinsu Zheng et al. discovered that TRQI improved pathological injury of lung tissues in mice infected with influenza virus, and had significant antiviral activity in influenza virus infected mice. The antiviral activity of TRQI might be due to its inhibition of cellular proliferation and enhancement of immunity (Zheng and Gu, 2009). Weifeng Yang et al. discovered that TRQI could destroy methicillin-resistant Staphylococcus aureus (MRSA) biofilm and induce its death. When combined with vancomycin or linezolid below the minimal inhibitory concentration (MIC) concentration, synergistic anti-biofilm activity was observed that was significantly higher than when using TRQI alone (Yang et al., 2018). Research by Yi Wang et al. showed that the efficacy of TRQI in the treatment of acute pneumonia was mediated by destruction of bacterial biofilm, which is different to the mechanism of penicillin (Wang Y. et al., 2011). Wei Liu et al. discovered that TRQI might treat airway mucus hypersecretion by regulating the interleukin-17 (IL-17) signaling pathway and its downstream protein MUC5AC. An in vivo experiment showed that TRQI could significantly inhibit excessive secretion of LPS-stimulated MUC5AC and expression of TNF-α, interleukin-6 (IL-6), IL-8, and IL-17A in terms of protein and mRNA levels (Liu W. et al., 2019).

Clinical Research on TRQI
Modern clinical studies have shown that TRQI has therapeutic efficacy against infectious diseases, such as viral pneumonia, MERS, human infection with H7N9 avian influenza, acute bronchitis, acute attack of chronic bronchitis, CAP, tuberculosis accompanied by infection, and AECOPD (see Table 3 ). TRQI has been recommended in MERS Diagnosis and Treatment Scheme (Version 2015) and Diagnosis and Treatment Scheme for Human Infection with H7N9 Avian Influenza (Version 1, 2017).
A systematic evaluation of eight published randomized and controlled trials that included a total of 590 adult patients with viral pneumonia found that TRQI had advantages in terms of response rate, faster change of chest radiography, average length of stay, and other aspects (Pan, 2016). Research results from Jinzhi Liang et al. showed that there was no statistically significant difference in the clinical effect of combined TRQI and Ribavirin or TRQI alone in the treatment of hand-foot-and-mouth disease. Both treatments were superior to that of Ribavirin alone (Liang et al., 2013). Research by Wang Pei et al. showed that potential benefits of TRQI in the treatment of acute bronchitis included improved response rate, and reduced fever, cough, crackles, and X-ray shadow absorption (Wang et al., 2016). Research results of Lini Gao et al. showed that combined use of TRQI and Western medicines was more effective than Western medicines alone in the treatment of acute bronchitis and gave superior improvement of clinical symptoms (Gao et al., 2019). Hongli Jiang et al. showed by systematic evaluation that administration of TRQI to treat CAP on the basis of antibiotics and symptomatic treatment significantly improved clinical symptoms. Cough with expectoration was improved, the duration of fever was shortened and recovery of chest radiography and hemogram were promoted without significant adverse reactions (Jiang et al., 2009). Lian Xiong et al. showed by systematic evaluation that TRQI might have the same overall effect as some antibacterial drugs in treatment of patients with tuberculosis accompanied by lung infection, but improved efficacy was observed in combination with antibacterial drugs. This might be due to the bacteriostatic effects of TRQI and elimination of inflammatory mediators (Lian et al., 2018). A total of 14 trials and 954 patients were included in a study by Yunqing Zhong, and the results showed that combined use of TRQI and antibacterial drugs improved the clinical effects and lung function in AECOPD patients, reduced pCO2, and shortened the length of stay without serious adverse reactions (Zhong et al., 2010).

Relevant Information on the Clinical Application of XYPI
Recommended Therapeutic Regimens
XYPI has been recommended in 15 therapeutic regimens of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of XYPI
Andrographolide total sulfonate. Basic information on XYPI is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With XYPI
XYPI is used for syndrome of exuberance of internal heat toxin in progressive stage of COVID-19 (critical case). Indicative symptoms are fever, sore throat, cough with yellow phlegm and chest distress. It could also be used to treat viral infection combined with mild bacterial infection.
Progress of Pharmacological Research on XYPI
The main ingredient of XYPI is andrographolide total sulfonate, which is antipyretic, anti-inflammatory, antiviral, antibacterial and immune-regulatory (see Table 3 ).
Yang Yu et al. conducted in vivo experiments with XYPI, and discovered that it could significantly protect mice infected with Staphylococcus aureus and Streptococcus pneumoniae, and significantly inhibited citric acid-induced cough frequency in guinea pigs (Yu et al., 2009). Using in vitro experiments, Lu Wang et al. studied the inhibitory effect of XYPI on inflammatory factors released by LPS-stimulated mouse mononuclear macrophages. The results showed that XYPI significantly inhibited the release of inflammatory factors such as TNF-α and IL-6 (Wang et al., 2008). Yinglan Nie et al. explored the mode of action of XYPI in the treatment of acute lung injury by observing its effect on cytokine content in bronchoalveolar lavage fluid (BALF) following LPS-induced acute lung injury. The results showed that XYPI could play an anti-inflammatory role by modulating the balance of pro-inflammatory/anti-inflammatory cytokines and prevent excess anti-inflammatory responses during the course of acute lung injury (Nie et al., 2012). Qi Liu et al. observed antiviral activity of XYPI against human rhinovirus-induced mouse infections. XYPI significantly reduced the virus titer in trachea-lung tissue homogenate of infected mice, effectively inhibiting proliferation of human rhinovirus in mice. Respiratory lesions were alleviated in tested animals, survival rate was improved, there were few adverse reactions, and it was an efficient and safe drug against human rhinovirus infection. Its specific mode of action, however, was unclear (Liu, 2015).
Clinical Research on XYPI
XYPI is a broad-spectrum antiviral Chinese patent medicine that is widely used to treat acute URI, viral pneumonia and pulmonary infection in clinical practice with good efficacy. Recent studies have discovered that it can also inhibit some viruses and bacteria, and could be used to treat influenza, human infection with H7N9 avian influenza, capillary bronchitis and other diseases (see Table 3 ). XYPI has been recommended in China’s Diagnosis and Treatment Scheme for Human Infection with H7N9 Avian Influenza (Version 2017).
Xiuping Yin et al. used the association rule method to analyze drug combinations, including XYPI in patients with pulmonary infection. The results showed that it could play a role as alternative or as a supplement to antibiotics in the treatment of pulmonary infection, but the safety and rationality of its use in drug combinations required further study in clinical practice (Yin et al., 2015). Guangming Li et al. conducted a retrospective analysis of 92 patients with viral pneumonia and found that XYPI was more effective than Ribavirin, providing significant improvement of symptoms (Li, 2015). Ruihan Qi et al. analyzed the therapeutic effect of XYPI in the treatment of viral pneumonia by systematic evaluation and found that it was more effective than Ribavirin. XYPI increased the cure rate, improved signs and symptoms, and reduced the incidence of adverse reactions (Qi et al., 2018). Lili Zhang et al. used XYPI in combination with Western medicine to treat severe pneumonia of the elderly in clinical practice. The results showed that it significantly shortened the course of disease, improved treatment efficiency, reduced the incidence of antibiotic resistance, reduced occurrence of double infection, improved the prognosis, and reduced mortality (Zhang and Wang, 2015). Zhixu Yang et al. observed the clinical effect of XYPI in treating the syndrome of phlegm-heat obstructing lung of severe pneumonia from the perspective of traditional Chinese medicine. The results showed significant improvements that included reduced fever, reduced numbers of leukocytes, improved oxygen index, lower clinical pulmonary infection score (CPIS), and reduced pulmonary inflammation. It also shortened the duration of mechanical ventilation and length of stay in ICU, and improved the clinical effect (Yang et al., 2014). In addition, XYPI has also shown significant efficacy in the treatment of URI. Xiaowen Liu et al. conducted a retrospective analysis of 660 patients with acute URI and found that the total response rate in the XYPI treatment group was significantly higher than that of the control group. The difference was statistically significant (Liu and Li, 2015).
Usage and Dosage of XYPI
1) Intramuscular injection. Adults: 50-100 mg, 2 or 3 times a day. 2) Intravenous drip. Adults: 250–500 mg a day, diluted with 0.9% sodium chloride or 5% glucose.
Adverse Reactions of XYPI
The main adverse reactions are allergic reaction, damage to the skin, damage to the digestive system, damage to the respiratory system, and general damage to the cardiovascular system. These are manifested by rash, itching, shivering, facial blushing, fever, cyanosis, difficulty breathing, nausea, vomiting, palpitations, chest distress, and allergic shock.
XYPI Precautions
1) Use is forbidden in pregnant women and children under 1 year of age. Use with caution in the elderly above 75 years of age. 2) Use is forbidden in those with a history of allergic or severe adverse reactions to this drug or preparations containing andrographolide total sulfonate. 3) Enhanced monitoring is recommended in patients using XYPI for the first time; pay close attention to reactions during administration, especially if discovering abnormalities within 30 min of administration. Stop administration immediately and take active rescue measures. 4) When used in combination with other injections, XYPI should be administered first. Other injections can be infused after flushing or replacing the infusion tube.

Relevant Information on the Clinical Application of XBJI
Recommended Therapeutic Regimens
XBJI has been recommended in 20 therapeutic regimens of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of XBJI
Carthamus tinctorius L. (Honghua), Paeonia lactiflora Pall. (Chishao), Conioselinum anthriscoides ‘Chuanxiong’ (Chuanxiong), Salvia miltiorrhiza Bunge (Danshen), and Angelica sinensis (Oliv.) Diels (Danggui). Basic information on XBJI is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With XBJI
XBJI is used for syndrome of blood-stasis and toxins in the progressive stage of COVID-19 (critical case). Indicative symptoms are fever, dyspnea and tachypnea, palpitations, and dysphoria. It could also be used for treatment of infection-induced systemic inflammatory response syndrome and multiple-organ dysfunction syndrome in the stage of impaired organ function.
Progress of Pharmacological Research on XBJI
Modern pharmacological studies have shown that XBJI is anti-inflammatory, antioxidant, immune-regulatory, and protects against acute lung injury (see Table 3 ).
Tiantian Li et al. found that in mice with MRSA-induced sepsis, XBJI protected the infected mice by downregulating expression of inflammatory cytokines stimulated by Pam3CSK4, MAPK, PI3K (phosphatidylinositol 3 kinase)/Akt and other pathways, thus, inhibiting the inflammatory response (Li T. T. et al., 2020). Shuwen Zhang et al. and Xi Chen et al. found that XBJI significantly reduced TNF-α, IL-6, and IL-10 levels in mice with sepsis, prevented neutrophil infiltration of lung and kidney, modulated T helper cell (Th) 1/Th2, Th17, and Tregs balance, reduced inflammatory response, and improved survival rate in mice with infectious shock (Zhang et al., 2006; Chen et al., 2018). Mingwei Liu et al. studied rats with paraquat-induced acute lung injury and discovered that XBJI could enhance immunity, reduce expression of inflammatory factors, and protect against acute lung injury by blocking p-38 MAPK and NF-κB p65 pathways, (Liu et al., 2014). Research by Yin Teng et al. found that XBJI in combination with conventional treatment significantly reduced interleukin-1 (IL-1), IL-6, and TNF-α levels, improved CD4+/CD8+ T lymphocyte ratio and NK cell relative activity, reduced inflammatory response, and enhanced cellular immunity in patients with severe pneumonia (Teng et al., 2012). Research by Hui Jin et al. showed that XBJI significantly improved the activity of superoxide dismutase (SOD), reduced reactive oxygen species (ROS) levels and protected against oxidative damage in mice under high-temperature stimulation (Jin et al., 2018). Research by Luo Peng et al. showed that XBJI downregulated MDA levels, upregulated SOD levels, and alleviated LPS-induced acute lung injury in rats (Luo and Zhou, 2017). In a rat model of oleic acid or LPS-induced acute lung injury, XBJI reduced TNF-α levels, alleviated pulmonary tissue edema and inflammatory cell infiltration, and protected against lung injury (Zhang et al., 2014). Research by Yuexia Ma et al. showed that although XBJI had no direct antiviral effect in mice with H1N1 severe pneumonia; it alleviated lung injury and protected against death, which might be due to its regulation of inflammatory cytokine levels in the early stage (Ma et al., 2015).
Clinical Research on XBJI
Modern clinical studies have shown that XBJI in combination with conventional treatment has therapeutic effects in relevant diseases, such as MERS, human infection with H7N9 avian influenza, CAP, severe pneumonia, systemic inflammatory response syndrome, COPD and sepsis (see Table 3 ). XBJI has been recommended in MERS Diagnosis and Treatment Scheme (Version 2015) and Diagnosis and Treatment Scheme for Human Infection with H7N9 Avian Influenza (Version 1, 2017).
Clinical research by Wen Long et al. randomly divided 60 severe COVID-19 patients into routine treatment (n = 20), XBJI 50 ml (n = 20), and XBJI 100 ml (n = 20) groups. On the basis of conventional treatment, XBJI (50 ml) was injected twice a day for 7 days in the XBJI 50 ml group, or 100 ml twice a day for 7 days in the XBJI 100 ml group. After treatment, the white blood cell count (WBC) and lymphocyte count (LYM) of the three groups increased, while CRP and ESR decreased. Compared with the routine treatment group, the WBC count in the XBJI 100 ml group after treatment significantly increased (×109/L: 7.12 ± 0.55 vs. 5.67 ± 0.51, p < 0.05), and the levels of CRP and ESR in the XBJI 50 ml and 100 ml groups significantly decreased [CRP (mg/L): 32.3 ± 4.6, 28.0 ± 6.2 vs. 37.3 ± 5.9; ESR (mm/h): 45.9 ± 5.7, 40.5 ± 7.4 vs. 55.3 ± 6.6, all p < 0.05]. Compared with the XBJI 50 ml group, the increase of WBC, and the decrease of CRP and ESR were more significant in the XBJI 100 ml group [WBC (×109/L): 7.12 ± 0.55 vs. 5.82 ± 0.49; CRP (mg/L): 28.0 ± 6.2 vs. 32.3 ± 4.6; ESR (mm/h): 40.5 ± 7.4 vs. 45.9 ± 5.7, all p < 0.05]. The APACHE II score of three groups decreased. In the XBJI 100 ml group, the APACHE II score after treatment was significantly lower than those in the routine treatment and XBJI 50 ml groups (12.3 ± 1.5 vs. 16.5 ± 1.6, 15.9 ± 1.4, both p < 0.05). After treatment, the 2019-nCoV nucleic acid test in the three groups partly turned negative: nine cases in the routine treatment group, eight cases in the XBJI 50 ml group and nine cases in the XBJI 100 ml group, with no significant differences (p > 0.05). The conditions of patients in the three groups were improved after treatment. Eight cases in the routine treatment group were transformed into common type and one case into critical type; nine cases and 12 cases in the XBJI 50 ml and 100 ml groups, respectively, were transformed into the common type. Patients in the XBJI 100 ml group improved more obviously than in the XBJI 50 ml and routine treatment groups (both p < 0.05). The XBJI injection can effectively improve the inflammatory markers and prognosis of severe COVID-19 patients (Wen et al., 2020).
Clinical research by Qi Fei et al. showed that, of 80 patients with severe pneumonia, those receiving a combination of XBJI and conventional treatment exhibited reduced levels of blood LDH, α1-acid glycoprotein (α1-AG) and α1-antitrypsin (α1-AT). Body temperature was reduced significantly and secretion of TNF-α, IL-6, IL-8, and other cytokines was inhibited. The total treatment efficiency was up to 80%, compared to 67.5% in the control group (Qi et al., 2011). An RCT study comprised of 33 centers and 710 patients conducted by Yuanlin Song et al. showed that XBJI in combination with conventional treatment significantly improved the primary endpoint, pneumonia severity index, in patients with severe CAP (the control group vs XBJI Group, 46.33% vs 60.78%, p < 0.001). There was also significantly reduced mortality in 28 days (24.65% vs 15.87%, p = 0.006), the duration of mechanical ventilation was shortened (11 vs 16.5 d, p = 0.012) and length of stay in ICU was reduced (12 vs 16 d, p = 0.004) (Song et al., 2019). Mingjin Zhu et al. conducted a meta-analysis of 12 studies with a total of 860 patients and showed that XBJI in combination with conventional treatment was superior to the treatment group in improving total response rate in patients with severe pneumonia. Infectious indicators (WBC, CRP, CPIS) and inflammatory cytokine (IL-6, IL-8, TNF-α) levels were reduced, and the average length of stay in hospital was reduced (Zhu et al., 2014). Wei Zhao et al. studied 56 patients with systemic inflammatory response syndrome (SIRS) and found that after 7 d treatment with XBJI in combination with conventional treatment, body temperature, WBC, and acute physiology and chronic health evaluation II (APACHE-II) score improved more significantly compared to the control group (p < 0.05). Expression of CD4+, CD4+/CD8+, CD14+/HLA-DR (human leukocyte antigen-DR) increased significantly, and the combination regulated the SIRS immune state and improved systemic status of the patients (Zhao W. et al., 2014). Clinical research found that XBJI in combination with conventional treatment lowered TNF-α, CRP, and other inflammatory indicators in AECOPD patients and had a certain therapeutic effect. In patients with accompanying SIRS, the combination significantly improved cough, expectoration, shortness of breath, and other clinical symptoms, and shortened hospital stay (Chen et al., 2011; Zhu et al., 2019). Meta-analysis by Chengyu Li et al. included sepsis patients from 16 RCTs (total 1,144 cases), and evidence of moderate intensity showed that XBJI in combination with conventional treatment effectively reduced the mortality rate of sepsis patients over 28 d (934/1144, p < 0.00001), APACHE-II score (792/1144, p < 0.00001) and body temperature (362/1144, p < 0.00001) (Li et al., 2018).
Usage and Dosage of XBJI

Progress of Pharmacological Research on XBJI
Modern pharmacological studies have shown that XBJI is anti-inflammatory, antioxidant, immune-regulatory, and protects against acute lung injury (see Table 3 ).
Tiantian Li et al. found that in mice with MRSA-induced sepsis, XBJI protected the infected mice by downregulating expression of inflammatory cytokines stimulated by Pam3CSK4, MAPK, PI3K (phosphatidylinositol 3 kinase)/Akt and other pathways, thus, inhibiting the inflammatory response (Li T. T. et al., 2020). Shuwen Zhang et al. and Xi Chen et al. found that XBJI significantly reduced TNF-α, IL-6, and IL-10 levels in mice with sepsis, prevented neutrophil infiltration of lung and kidney, modulated T helper cell (Th) 1/Th2, Th17, and Tregs balance, reduced inflammatory response, and improved survival rate in mice with infectious shock (Zhang et al., 2006; Chen et al., 2018). Mingwei Liu et al. studied rats with paraquat-induced acute lung injury and discovered that XBJI could enhance immunity, reduce expression of inflammatory factors, and protect against acute lung injury by blocking p-38 MAPK and NF-κB p65 pathways, (Liu et al., 2014). Research by Yin Teng et al. found that XBJI in combination with conventional treatment significantly reduced interleukin-1 (IL-1), IL-6, and TNF-α levels, improved CD4+/CD8+ T lymphocyte ratio and NK cell relative activity, reduced inflammatory response, and enhanced cellular immunity in patients with severe pneumonia (Teng et al., 2012). Research by Hui Jin et al. showed that XBJI significantly improved the activity of superoxide dismutase (SOD), reduced reactive oxygen species (ROS) levels and protected against oxidative damage in mice under high-temperature stimulation (Jin et al., 2018). Research by Luo Peng et al. showed that XBJI downregulated MDA levels, upregulated SOD levels, and alleviated LPS-induced acute lung injury in rats (Luo and Zhou, 2017). In a rat model of oleic acid or LPS-induced acute lung injury, XBJI reduced TNF-α levels, alleviated pulmonary tissue edema and inflammatory cell infiltration, and protected against lung injury (Zhang et al., 2014). Research by Yuexia Ma et al. showed that although XBJI had no direct antiviral effect in mice with H1N1 severe pneumonia; it alleviated lung injury and protected against death, which might be due to its regulation of inflammatory cytokine levels in the early stage (Ma et al., 2015).

Relevant Information on the Clinical Application of SFI
Recommended Therapeutic Regimens
SFI has been recommended in 19 therapeutic regimens of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of SFI
Panax ginseng C.A.Mey. (Hongshen) and Aconitum carmichaeli Debeaux (Fuzi). Basic information on SFI is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With SFI
SFI is used for deliverance due to sudden yang deficiency in the progressive stage of COVID-19 (critical case). Indicative symptoms are dyspnea, pale complexion, and severe symptoms are unconsciousness, drip sweat, and cold limbs.
Progress of Pharmacological Research on SFI
Modern pharmacological studies have shown that SFI has functions, including anti-shock, and protection from lung injury (see Table 3 ).
Yuhang Ai et al. explored the effects and mechanism of SFI in an LPS-induced lung injury model in rats. The results indicated that SFI might protect the lung by reducing activation of NF-κB in lung tissue (Ai et al., 2006). Research by Xia Liu et al. found that SFI improved the inflammatory response of rat lung tissue in an LPS shock model by reducing expression of p65 and p50 mRNA and protein in lung tissue and serum TNF-α (Liu et al., 2019a). Li Lin et al. studied the impact of SFI on LPS acute lung injury in rats, and found that SFI significantly increased the wet/dry weight ratio (W/D) of lung tissue, neutrophil ratio in BALF, protein content, lung tissue MDA, and serum NO. It significantly alleviated injury in lung tissue, indicating that SFI had an important preventive and therapeutic effect on LPS-induced acute lung injury (Lin and Zhan, 2010). Xi Liu et al. used the LPS intravenous injection method to establish a septic shock model in rabbits. Administration of SFI significantly improved mean arterial pressure (MAP), reduced LPS, LDH, and AST serum levels, and significantly improved the morphology of heart, liver, and kidney. In addition, SFI increased levels of adenosine triphosphate (ATP) and taurine in the heart, while reducing the level of adenosine monophosphate (AMP) in the heart. The results showed that SFI had a significant protective effect against LPS-induced septic shock (Liu et al., 2019b).
Clinical Research on SFI
SFI is composed of Panax ginseng C.A.Mey. and Aconitum carmichaeli Debeaux, and has properties that include enhancing cardiac function, increasing blood pressure, and protecting ischemic myocardium. It is widely used to rescue from shock (infectious or cardiogenic shock) caused by various reasons, cardiac failure, and arrhythmia in clinical practice. Recent studies have shown that SFI significantly protects against lung injury (see Table 3 ). SFI has been recommended in China’s SARS Diagnosis and Treatment Scheme (Version 2004), the MERS Diagnosis and Treatment Scheme (Version 2015), and the Diagnosis and Treatment Scheme for Human Infections with H7N9 Avian Influenza (Version 2017).
Qiu Z.L. et al. observed a therapeutic effect of SFI in patients with severe sepsis and an impact on the expression levels of serum IL-6 and IL-10. They found that SFI significantly lowered IL-6 levels in patients with severe sepsis and regulated the balance between pro- and anti-inflammatory factors, thus, improving the therapeutic effect (Qiu et al., 2012). Ning Zhang et al. randomized 160 patients with sepsis into an SFI treatment group and a conventional treatment group. By collecting post-treatment immunological parameters, they conducted a comparative analysis of the impact on immune function. The results showed that patients in the SFI treatment group had increased CD4+ and CD8+ T cell counts in peripheral blood and upregulated HLA-DR expression in monocytes. In addition, the SFI treatment group had a better response than the control group for duration of vasopressor administration and APACHE-II score. The results showed that SFI enhanced cellular immune function in patients with septic shock and might become an important adjunctive therapy for sepsis patients (Zhang et al., 2017). Another study found that SFI played an active role in the treatment of severe pneumonia in the elderly. Among 89 elderly patients with severe pneumonia, the SFI treatment group had significantly decreased levels of TNF-α, IL-6, and IL-8 7 days after administration, indicating that SFI effectively reduced inflammatory mediators, thus, playing an active therapeutic effect (Lv et al., 2017). Min Ma et al. conducted clinical research on 80 patients with traumatic acute lung injury, and found that SFI significantly improved respiratory rate, improved the oxygen index, and reduced levels of intracellular adhesion molecule 1 (ICAM-1), endothelin-1 (ET-1), and NO, thus, improving prognosis of these patients. This study provided a potential new therapy for traumatic acute lung injury (Ma et al., 2019). Jie Li et al. observed an impact of SFI intervention on duration of mechanical ventilation in patients with respiratory failure. The results showed that the total response rate in the SFI group was higher than that of the control group. SFI significantly improved serum prealbumin and high-sensitivity CRP levels in patients with respiratory failure and improved their oxygen index, thus, shortening the duration of mechanical ventilation (Li, 2013).
Usage and Dosage of SFI
1) Intravenous drip: 20–100 ml, diluted in 250–500 ml of 5%–10% glucose injection. 2) Intravenous injection: 5–20 ml, diluted in 20 ml of 5%–10% glucose injection.
Adverse Reactions of SFI
Dizziness, headache, shivering, fever, palpitations, chest distress, chest pain, difficulty breathing, nausea, retching, abdominal pain, rash, itching, rash or swelling, pain, and other discomfort in local infusion site.
SFI Precautions
1) To be used with caution in pregnant women. 2) Avoid direct mixing with coenzyme A, VitK3, and aminophylline. 3) Prepared drug should be used within 4 h.

Relevant Information on the Clinical Application of SMI
Recommended Therapeutic Regimens
SMI has been recommended in 18 therapeutic regimens of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of SMI
Panax ginseng C.A.Mey. (Hongshen) and Ophiopogon japonicus (Thunb.) Ker Gawl. (Maidong). Basic information on SMI is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With SMI
SMI is used for the syndrome of deficiency of both qi and yin and deficiency of pulse in the progressive stage of COVID-19 (critical case). Indicative symptoms are weakness and shortness of breath, tachypnea, palpitations, dry mouth, sweating, and even dysphoria and cold limbs.
Progress of Pharmacological Research on SMI
Modern pharmacological studies have shown that SMI has functions that include protection from inflammatory shock, protection of heart and lung function, and immunoregulation (see Table 3 ).
Y. Z. Zhang et al. observed that SMI had strong anti-shock and neuroprotective properties in LPS-induced shock, possibly due to inhibition of brain lipid peroxidation and improvement of SOD activity (Zhang Y. Z. et al., 2010). SMI suppressed apoptosis of lung tissue cells during pulmonary ischemia/reperfusion injury in rabbits, resulting in attenuation of pneumocyte injury by raising NO levels, lowering oxygen free radical levels, and decreasing lipid peroxidation (Lin et al., 2007). It has also been reported that SMI reduced expression of NF-κB and activity of inducible nitric oxide synthase (iNOS) in lung tissues of rats poisoned by paraquat, and significantly alleviated erythrocyte diapedesis in the alveolar space (Liu et al., 2009). Research by Shuhua Xu et al. showed that SMI improved cardiac function and significantly improved hemodynamics in rats with cardiac failure. In addition, it improved the oxygen supply to tissues and the capacity of the tissues to use oxygen, thus, improving oxygen metabolism (Xu and Liu, 2010). SMI also inhibited expression of ICAM-1 and vascular cell adhesion molecule 1 (VCAM-1) to alleviate inflammatory infiltration following ischemia/reperfusion, and alleviated myocardial ischemia/reperfusion injury caused by multiple inflammatory responses (Liu et al., 2015). It also inhibited generation of inflammatory cytokines in rats subjected to ischemia/reperfusion, reduced serum expression of TNF-α, IL-6, IL-8, etc., thus, alleviating inflammatory factor-induced cardiomyocyte injury and improving immune function (Wang et al., 2015). Research by Xuan Liu et al. discovered that SMI inhibited MCP-1, which indicated that SMI might be important in the inhibition of monocyte and macrophage activation (Liu et al., 2015). Lihua Du discovered that SMI significantly increased the weights of thymus and spleen in mice, raised serum IgG levels and the number of T cells, enhanced the phagocytic function of macrophages and had a significant immunomodulatory effect.
Clinical Research on SMI
SFI has often been used to treat shock caused by various factors, COPD, systematic inflammatory response syndrome and other diseases in clinical practice (see Table 3 ). SMI has been recommended in China’s SARS Diagnosis and Treatment Scheme (Version 2004) and MERS Diagnosis and Treatment Scheme (Version 2015).
Biao Deng et al. studied 71 patients with shock and found that SMI in combination with conventional Western medicine had definite therapeutic efficacy, shortened the course of disease, reduced the length of hospital stay, and lowered the fatality rate (Deng et al., 2006). Hefeng Qin observed 68 patients with infectious shock and found that SMI had good clinical efficacy. It significantly improved CRP, PCT and TNF-α serum levels, and shortened the recovery time of vital signs with few adverse reactions (Qin, 2014). Wang Xian’an et al. observed 80 patients treated for infectious shock, and discovered that SMI in combination with ulinastatin had a significant therapeutic effect, enhancing immune function, and alleviating the inflammatory response (Wang et al., 2017). X. Huang et al. evaluated 23 RCTs with a total of 1,804 participants to study the impact of SMI on COPD. The results showed that SMI not only increased the total clinical response rate, but also improved pulmonary function, blood gas, and IgG indexes, and shortened the time for disappearance of lung rales. The results indicated that SMI in combination with Western medicine might have a positive effect in the treatment of COPD (Huang et al., 2019). Zongjun Fang et al. studied 38 patients with COPD. The control group (18 cases) received conventional Western medicine, while 20 cases (the treatment group) received SMI in addition. The results showed that patients in the treatment group had better vital capacity, forced expiratory volume in 1 s (FEV1), maximal breathing capacity (MBC), maximal inspiratory pressure (MIP), load breathing time, arterial blood gas analysis, and Burp dyspnea scores than the control group or the pre-treatment patients. The treatment group also had significantly improved respiratory function and clinical symptoms (Fang et al., 1998). Changxing Guo et al. randomized 33 patients with systemic inflammatory response syndrome into a conventional Western medicine treatment group (15 cases) and SMI + conventional treatment group (18 cases). After treatment, patients in the SMI treatment group had increased prostacyclin PGI2 and PGI2/thromboxane A2 (TXA2) in blood to a certain extent compared to patients in the conventional treatment group. Patients in the SMI group also had decreased levels of TXA2, atrial natriuretic peptide (ANP) and endothelin, and there were significant differences between the two groups. The results indicated that SMI could play an active role in improving microcirculation, protecting organ functions, and preventing further occurrence and development of systemic inflammatory response syndrome (Guo et al., 2004).
Usage and Dosage of SMI
Intravenous drip, 20–60 ml diluted with 250–500 ml of 5% glucose injection.
Adverse Reactions of SMI
The adverse reactions mainly include immediate hypersensitivity, predominantly skin allergy manifested by itching, rash, systematic urticaria, and then allergic shock; there may also be serious abdominal distension, corneal edema, abnormal vision, hypotension, ascending vascular pain, acute hepatic damage, sinus arrest, and drug fever.
SMI Precautions
1) Not to be used in newborns, infants, pregnant women, or those with an allergic constitution. 2) Not for administration by intravenous injection. The administration speed should not be too fast. In those receiving the drug for the first time, the initial administration should be at 15 drips/min for 10 min. If there are no abnormalities, the speed of administration can be increased to normal, which is generally controlled at 40–50 drips/min. 3) This drug has a pressor response, and blood pressure should be monitored in hypertensive patients.

The results showed that SMI not only increased the total clinical response rate, but also improved pulmonary function, blood gas, and IgG indexes, and shortened the time for disappearance of lung rales. The results indicated that SMI in combination with Western medicine might have a positive effect in the treatment of COPD (Huang et al., 2019). Zongjun Fang et al. studied 38 patients with COPD. The control group (18 cases) received conventional Western medicine, while 20 cases (the treatment group) received SMI in addition. The results showed that patients in the treatment group had better vital capacity, forced expiratory volume in 1 s (FEV1), maximal breathing capacity (MBC), maximal inspiratory pressure (MIP), load breathing time, arterial blood gas analysis, and Burp dyspnea scores than the control group or the pre-treatment patients. The treatment group also had significantly improved respiratory function and clinical symptoms (Fang et al., 1998). Changxing Guo et al. randomized 33 patients with systemic inflammatory response syndrome into a conventional Western medicine treatment group (15 cases) and SMI + conventional treatment group (18 cases). After treatment, patients in the SMI treatment group had increased prostacyclin PGI2 and PGI2/thromboxane A2 (TXA2) in blood to a certain extent compared to patients in the conventional treatment group. Patients in the SMI group also had decreased levels of TXA2, atrial natriuretic peptide (ANP) and endothelin, and there were significant differences between the two groups. The results indicated that SMI could play an active role in improving microcirculation, protecting organ functions, and preventing further occurrence and development of systemic inflammatory response syndrome (Guo et al., 2004).

Biao Deng et al. studied 71 patients with shock and found that SMI in combination with conventional Western medicine had definite therapeutic efficacy, shortened the course of disease, reduced the length of hospital stay, and lowered the fatality rate (Deng et al., 2006). Hefeng Qin observed 68 patients with infectious shock and found that SMI had good clinical efficacy. It significantly improved CRP, PCT and TNF-α serum levels, and shortened the recovery time of vital signs with few adverse reactions (Qin, 2014). Wang Xian’an et al. observed 80 patients treated for infectious shock, and discovered that SMI in combination with ulinastatin had a significant therapeutic effect, enhancing immune function, and alleviating the inflammatory response (Wang et al., 2017).

Relevant Information on the Clinical Application of AGNHP
Recommended Therapeutic Regimens
AGNHP has been recommended in 21 therapeutic regimens of COVID-19 in China (see detailed information in Tables 1 and 2 ).
Ingredients of AGNHP
Curcuma kwangsiensis S.G.Lee & C.F.Liang (Yujin), Calculus Bovis (Niuhuang), Cornu Bubali (Shuiniujiao), Coptis chinensis Franch. (Huanglian), Cinnabaris (Zhusha), Moschus (Shexiang), Margarita (Zhenzhu), Realgar (Xionghuang), Scutellaria baicalensis Georgi (Huangqin), Gardenia jasminoides J.Ellis (Zhizi), and Cinnamomum camphora (L.) J.Presl (Bingpian). Basic information on AGNHP is provided in the Supplementary Table .
Indications for the Treatment of COVID-19 With AGNHP
AGNHP is used for the syndrome of epidemic toxin lung closure and inner blocking causing collapse in the progressive stage of COVID-19 (critical case). Indicative symptoms are hyper-pyretic convulsions, coma and delirium, difficulty breathing, and dysphoria.
Progress of Pharmacological Research on AGNHP
Modern pharmacological studies have shown that AGNHP has antipyretic, analgesic, anti-inflammatory, and neuroprotective effects (see Table 3 ).
Zuguang Ye et al. discovered that AGNHP could significantly reduce the body temperature of hyperpyrexic rabbits in a fever model induced by intravenous injection of typhoid Vi polysaccharide vaccine in rabbit ear (Ye et al., 2003). Feng Zhang, Kunjie Zhu et al. found in an LPS-induced intracerebral inflammation model that AGNHP antagonized the toxic effect of LPS on dopaminergic neurons, inhibited release of superoxide radical, and reverse changes in cortical monoamine neurotransmitters. It was speculated that its impact on cortical monoamine neurotransmitters might be one of the mechanisms by which AGNHP promoted consciousness in LPS brain damage (Zhang F. et al., 2010; Zhu and Sun, 2014). Research by Dan Zhang et al. showed that AGNHP lowered serum LPS and lung myeloperoxidase (MPO) levels in a rat model of sepsis (Zhang et al., 2009). Yishan Tang et al. found that AGNHP lowered total LDH activity in serum and brain tissue, and changed the percentage of isomerase in a rat pertussis-induced infectious cerebral edema model (Tang et al., 2005). Fan Q et al. discovered that AGNHP had anti-atherosclerotic effects in the high fat diet-induced ApoE−/− mouse model at early- and mid-stage via regulation of Th17/Treg balance. It inhibited chronic inflammation, reduced plaque collagen fibers, and reduced inflammatory cell infiltration (Fan et al., 2020).
Clinical Research on AGNHP
Modern clinical studies have shown that AGNHP has therapeutic effects against hyperpyrexia, coma caused by severe infectious diseases, and viral encephalitis and severe pneumonia of infants (see Table 3 ).
Yueming Feng et al. conducted a systematic evaluation and found that AGNHP could be used to promote consciousness of coma patients with acute cerebral infarction (ACI) and improve neurologic function. This may be due to the ability of AGNHP to alleviate the inflammatory response, reduce cerebral edema, and promote recovery of neurologic function (Feng and Yang, 2015). Haijun Zhang et al. discovered through clinical observation that AGNHP could be used to treat viral encephalitis in children. AGNHP rapidly reduced body temperature, prevented convulsions, promoted consciousness, and alleviated cerebral edema and brain cell damage (Zhang and Dong, 2014). Research by Zhulin Zhuo et al. found that AGNHP with the adjuvant, Ribavirin was efficacious in acute severe viral pneumonia of children, significantly reduced PCT and improved immune function (Zhuo and Wen, 2017). Yanling Shi discovered through clinical observation that AGNHP in combination with sodium phosphate improved anoxic conditions and myocardial damage in patients with neonatal asphyxia and myocardial damage (Shi, 2019). Xie Long et al. in a study of 70 patients with ACI and central hyperpyrexia found that combined use of conventional Western medicine and AGNHP reduced the duration of fever and significantly improved the prognosis (Long and Wu, 2014). Hanwei Liu et al. conducted a systematic review of relevant literature on AGNHP treatment of ACI and cerebral hemorrhage. The results showed that adjuvant treatment with ANP (AGNHP) appeared to improve the total response rate and neurologic deficit score in patients with ACI and acute intracerebral hemorrhage (AIH) (Han et al., 2019). Research by Ma et al. showed that ANP had a moderating effect on Th1/Th2 in cerebral infarction patients (Ma and Zhou, 2015).
Usage and Dosage of AGNHP
Oral administration. 3 g, once a day.
Adverse Reactions of AGNHP
Overdose administration might cause mercurial nephrosis or allergic reaction and other adverse reactions. Improper use of this product might cause hypothermia.
AGNHP Precautions
1) Nasogastric administration can be used in patients unable to take orally because of high fever and coma. The pills can be dissolved in warm but not hot water. The water or decoction used to dissolve the pills should be controlled at 40–60°C. The use of boiling water is forbidden for two reasons: first, to avoid increased decomposition of realgar and cinnabar by high temperature, and reduce generation of the highly toxic arsenic trioxide, free arsenium, and mercury. Research has shown that arsenic trioxide in realgar preparations is not significantly changed below 60°C but begins to increase at 80°C. The decoction used for dissolving AGNHP should therefore not exceed 60°C secondly, musk, borneol and other aromatic substances are volatile. Boiling water could result in excess volatilization, thus, reducing efficacy. 2) Must not be used with nitrate, nitrite, ferrite or sulfate drugs. 3) Not for use in pregnant women. 4) It contains cinnabar and realgar, and should not be taken at high doses for long periods. Should be used with caution in those with hepatic and renal dysfunction. (5) It contains musk, so athletes should use with caution.

Discussion and Conclusions
It is a critical moment in the battle to defeat the current outbreak of novel coronavirus. For this specific indication, rapid performance of TCM can contribute as an alternative measure. TCM can effectively prevent the disease from transforming into severe and critical disease. In severe cases, TCM has won time for recovery by improving symptoms (The State Council Information Office of the People’s Republic of China, 2020). Treatment practice for COVID-19 has shown that early intervention with TCM is an important method to improve cure rate, shorten the course of disease, delay disease progression and reduce mortality rate. For example, the total response rate of Qingfei Paidu Decoction was more than 90% in Shanxi and Hebei provinces (He et al., 2020).
CPMs have played an important role in preventing and treating epidemic diseases in China because they are convenient to use, easily stored and cost-effective. The positive role of CPMs has been emphasized in the “Diagnosis and Treatment of COVID-19 (Trial Version 7)” and other therapeutic regimens. During the medical observation period and early stage of COVID-19, HXZQC, LHQWC, SFJDC, and JHQGG can be selected according to different clinical manifestations. At the same time, they can also promote immunity against the virus. For severe and critical disease, the choice shall be made according to different syndromes during clinical treatment. For viral infections combined with mild bacterial infections, XYPI and TRQI can be used; for high fever with disturbance of consciousness, AGNHP can be used; for systemic inflammatory response syndrome or multiple organ function failure, XBJI is recommended; SMI can be used for immunosuppression; and SFI can be used for shock. Furthermore, the reason that TCM works is not only because it inhibits the virus, but also because it might block infection, regulate the immune response, inhibit the inflammatory storm, and promote repair of the body. Moreover, the prevention and control measures of COVID-19 have fully reflected the ideology of “preventive treatment of disease”.
Physicians should pay attention to the reasonable application of CPMs to treat COVID-19. Severe patients are prone to septic shock, and liver and kidney dysfunction. In patients with related underlying diseases, drug metabolism and clearance are reduced. Treatment options: hepato-renal toxic drugs should be avoided to reduce the risk of drug accumulation and poisoning. For example, AGNHP contains cinnabar and realgar, and should not be taken for a long time. People with liver and kidney dysfunction should use with caution. TRQI should be carefully selected because it aggravates liver and kidney function; LHQWC and JHQGG contain ephedrae herba (Mahuang), and doctors need to monitor patients’ blood pressure, heart condition and combined use of antihypertensive drugs. In clinical application of XBJI, SFI and other traditional Chinese medicine injections, attention should be paid to the choice of solvent and the interval between infusions with other drugs. As is well known, clinicians use CPMs under the guidance of the theory of TCM. Foreign doctors and patients wishing to use CPMs to treat COVID-19 should exercise caution, especially in countries where they may be used incorrectly without the knowledge of TCM theory.
There are some limitations within this paper. First, as there is little direct clinical evidence for the prevention of COVID-19, the reported studies are from previous reports on the prevention of SARS, MERS, H7N9, and H1N1 influenza by CPMs, which can only be considered as indirect evidence in respect of the current outbreak. Secondly, the programs for prevention of COVID-19 were issued shortly after the outbreak. Chinese medicine experts suggested CPMs to treat COVID-19 based on their previous experience in the prevention and treatment of similar diseases combined with their initial understanding of the disease. The actual effects of these programs need to be verified in clinical application, and updated and improved according to the evidence of new research on COVID-19.
For future studies, we recommend prospective cohort studies, RCTs or registry studies to evaluate the effect of CPMs in prevention of COVID-19. Some clinical trial protocols to treat COVID-19 using the top 10 CPMs are ongoing (see Table 4 ). At present, since COVID-19 has not yet been controlled, a series of prospective population studies with rigorous design and large sample should commence with protocol registration, and implementation in a timely manner, to produce reliable evidence for CM prevention of COVID-19 or similar emerging respiratory infectious diseases in the future.

Discussion and Conclusions
|
|
p
|
It is a critical moment in the battle to defeat the current outbreak of novel coronavirus. For this specific indication, rapid performance of TCM can contribute as an alternative measure. TCM can effectively prevent the disease from transforming into severe and critical disease. In severe cases, TCM has won time for recovery by improving symptoms (The State Council Information Office of the People’s Republic of China, 2020). Treatment practice for COVID-19 has shown that early intervention with TCM is an important method to improve cure rate, shorten the course of disease, delay disease progression and reduce mortality rate. For example, the total response rate of Qingfei Paidu Decoction was more than 90% in Shanxi and Hebei provinces (He et al., 2020).

CPMs have played an important role in preventing and treating epidemic diseases in China because they are convenient to use, easily stored and cost-effective. The positive role of CPMs has been emphasized in the “Diagnosis and Treatment of COVID-19 (Trial Version 7)” and other therapeutic regimens. During the medical observation period and early stage of COVID-19, HXZQC, LHQWC, SFJDC, and JHQGG can be selected according to different clinical manifestations. At the same time, they can also promote immunity against the virus. For severe and critical disease, the choice shall be made according to different syndromes during clinical treatment. For viral infections combined with mild bacterial infections, XYPI and TRQI can be used; for high fever with disturbance of consciousness, AGNHP can be used; for systemic inflammatory response syndrome or multiple organ function failure, XBJI is recommended; SMI can be used for immunosuppression; and SFI can be used for shock. Furthermore, the reason that TCM works is not only because it inhibits the virus, but also because it might block infection, regulate the immune response, inhibit the inflammatory storm, and promote repair of the body. Moreover, the prevention and control measures of COVID-19 have fully reflected the ideology of “preventive treatment of disease”.

Physicians should pay attention to the reasonable application of CPMs to treat COVID-19. Severe patients are prone to septic shock, and liver and kidney dysfunction. In patients with related underlying diseases, drug metabolism and clearance are reduced. Treatment options: hepato-renal toxic drugs should be avoided to reduce the risk of drug accumulation and poisoning. For example, AGNHP contains cinnabar and realgar, and should not be taken for a long time. People with liver and kidney dysfunction should use with caution. TRQI should be carefully selected because it aggravates liver and kidney function; LHQWC and JHQGG contain ephedrae herba (Mahuang), and doctors need to monitor patients’ blood pressure, heart condition and combined use of antihypertensive drugs. In clinical application of XBJI, SFI and other traditional Chinese medicine injections, attention should be paid to the choice of solvent and the interval between infusions with other drugs. As is well known, clinicians use CPMs under the guidance of the theory of TCM. Foreign doctors and patients wishing to use CPMs to treat COVID-19 should exercise caution, especially in countries where they may be used incorrectly without the knowledge of TCM theory.

There are some limitations within this paper. First, as there is little direct clinical evidence for the prevention of COVID-19, the reported studies are from previous reports on the prevention of SARS, MERS, H7N9, and H1N1 influenza by CPMs, which can only be considered as indirect evidence in respect of the current outbreak. Secondly, the programs for prevention of COVID-19 were issued shortly after the outbreak. Chinese medicine experts suggested CPMs to treat COVID-19 based on their previous experience in the prevention and treatment of similar diseases combined with their initial understanding of the disease. The actual effects of these programs need to be verified in clinical application, and updated and improved according to the evidence of new research on COVID-19.
|
|
p
|
For future studies, we recommend prospective cohort studies, RCTs or registry studies to evaluate the effect of CPMs in prevention of COVID-19. Some clinical trial protocols to treat COVID-19 using the top 10 CPMs are ongoing (see Table 4 ). At present, since COVID-19 has not yet been controlled, a series of prospective population studies with rigorous design and large sample should commence with protocol registration, and implementation in a timely manner, to produce reliable evidence for CM prevention of COVID-19 or similar emerging respiratory infectious diseases in the future.
