This review has several limitations. First, the results of this review were obtained after standardizing the terms of the PIs and herbal formulae. Therefore, there might be a difference in the terms used in the provided guidelines. Second, this review does not include any direct evidence on the efficacy of traditional medicine in the clinical treatment of COVID-19. The results provided by this review are a summary of the traditional medicine guidelines, which can only be considered as guidance, and clinical verification is still required. Third, although this review summarized the most recent version of the national and provincial guidelines available up to March 6, 2020, the guidelines issued on COVID-19 by the Chinese government are constantly and frequently updated.
