A brief discussion on evidence-based clinical research of traditional Chinese medicine

Background: The evaluation of clinical efficacy of traditional Chinese medicine (TCM) is the focus of the development of Chinese medicine, but at present there is no internationally recognized clinical efficacy evaluation system, which prevents TCM going abroad. Evidence-based medicine (EBM) research methods have achieved good results in the evaluation of TCM, but there are still some problems. How to use EBM methods in accordance with China's national conditions and develop evidence-based TCM that meets its own characteristics is the key to the current discussion. Methods: Search websites such as PubMed, China National Knowledge Infrastructure, Wanfang Data and VIP by computer, and search papers related to evidence-based clinical research of TCM. Results: A total of 15 high quality representative research papers published in internationally renowned journals were selected for example, including 4 randomized controlled trials (RCTs) related to Chinese medicine, 9 RCTs related to acupuncture, and 2 observational studies on the safety of TCM. Conclusions: EBM method is suitable for clinical research of TCM. There are differences between "disease" and "syndromes" in the use of TCM. Based on the further standardization of syndromes and classification of TCM, modern clinical research methods can be reasonably applied. However, the quality of clinical research related to TCM is not high, and there is a lack of research related to the safety of it, which should be paid attention to and improved in future research.
