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).
