[Cognition innovation of toxicity of Chinese medicine and safe and precise medication].

ABSTRACT

Traditional Chinese medicine(TCM) has made outstanding contributions to disease prevention and treatment, survival, and reproduction of the Chinese nation. Currently, the inheritance and innovative development of TCM have become a national strategy. However, in recent years, adverse reactions/events of Chinese medicine frequently occurred. In particular, in terms of the safety problem of newly discovered "toxic" Chinese medicine, it is often difficult to answer the question scientifically and develop effective solutions. When facing international public opinions and public questioning, they are often "passively criticized". To solve the difficult problem about the safety of Chinese medicine, we urgently need to make breakthroughs in the cognition of toxicity of Chinese medicine and prevention and control of risks. This research team has been committed to the research on the safety of Chinese medicine for the long term. In particular, in terms of safety evaluation and risk prevention and control of newly discovered "toxic" Chinese medicine, they have made a series of original discoveries. On the basis of the discoveries, they innovated the cognition theory and methods of the toxicity of Chinese medicine, opened up a new field of research on the idiosyncratic toxicity and indirect toxicity of Chinese medicine, and proposed and established the disease-syndrome-based toxicology(DSBT), the model and method of safety evaluation of Chinese medicine related to diseases and syndromes. In light of the theory and methods of DSBT which have been applied to the objective eva-luation and analysis of the mechanism of the hepatotoxicity of Chinese medicine such as Polygoni Multiflori Radix, the mechanism hypothesis of "toxicity due to three causes" of idiosyncratic hepatotoxicity of Chinese medicine was proposed and confirmed. The findings revealed that the substances that induced idiosyncratic or indirect toxicity in Chinese medicine often did not possess definite direct toxi-city. Therefore, this research team proposed the concept of toxicity-related substances(TRS) in Chinese medicine. Based on the mo-dern scientific cognition of toxicity of Chinese medicine, the team proposed the strategy and method of Chinese medicine compatibility to reduce the toxicity based on the component-effect-target interaction to underpin the demonstration of the scientific connotation of toxicity and side effects of "toxic" Chinese medicine and establishment of scientific and effective risk prevention and control strategies. In light of the innovative development of toxicity cognition of Chinese medicine, this study is expected to provide important theoretical guidance and methodological support for scientific evaluation and precise prevention and control of the safety risk of "toxic" Chinese medicine.
