BackgroundUntil June 2022, more than 540.9 million people had been diagnosed with COVID-19, and the pandemic had claimed more than six million lives worldwide. Two years after fighting the virus, we faced a more uncertain position. SARS-CoV-2 is constantly mutating and reappears regularly, particularly with Omicron variants showing high genetic variation and immune escape mechanisms. The efficacy and duration of protection of existing vaccines against new variants of SARS-CoV-2 remains uncertain. The world needs time to develop new variant-specific drugs, including monoclonal topics, vaccines, and other antiviral drugs, to fight the epidemic.ObjectiveThe aim of this study was to illustrate the scientific, effective and systematic nature of three classical prescriptions of traditional Chinese medicine (TCM) for the treatment of COVID-19 through comparison of disease symptoms, diagnostic process, and treatment methods and evidence-based and pharmacological studies.MethodsWe analysed the "Diagnosis and Treatment Protocol for Novel Coronavirus Pneumonia" (Version 9) made by China, "WHO-2019-nCoV-therapeutics", "Therapeutic Guidelines" published by Australian Therapeutic Guidelines Limited, "Shanghan Lun (Treatise on Febrile Diseases)", "Jinkui Yaolue (Golden Chamber Synopsis), and "Wenyi Lun (The Epidemic Febrile Disease)". We manually retrieved the dictionary of traditional Chinese medicine (Version II). In addition, we searched the Wiley online library, National Center for Biotechnology Information (NCBI), VIP, WHO website, and China National Knowledge Infrastructure (CNKI) for relevant literature from 2001 to 2022. We searched the original plants, ingredients, pharmacology, functions and indications, usage and dosage, drug efficacy, literature sources, and conduct an evidence-based studies. We quantified the strength of pharmacological action to show the pertinence of disease development.ResultsWe found that the diagnosis and treatment of pulmonary infection caused by epidemic disease in TCM classics is consistent with the diagnostic process of modern medical therapeutic guidelines. The three classic prescriptions have significant symptomatic therapeutic effects on the respiratory, gastrointestinal, urinary and hematological symptoms of the clinical manifestations of COVID-19. It was found that the herbal functional group of Houpo (Cortex Magnoliae Officinalis), Chaihu (Radix Bupleuri), Cangzhu (Rhizoma Atractylodis), Qianghuo (Notopterygii Rhizoma et Radix), etc showed strong anti-inflammatory activity and had a positive effect on treating and preventing the outbreaks of systemic inflammatory factors.ConclusionTCM can obtain obvious curative effect in symptomatic treatment, has strong anti-inflammatory effect, and can effectively reduce symptoms and patients' pain.© 2023 Song D et al.
