RESUMO
Traditional Chinese medicine boasts aunique theoretical system and rich practical experience. However, traditional Chinese medicine has an unclear material basis, vague pharmacological mechanism, and potential toxicity, which is the key factor to hinder its modernization and wide application. Therefore, when the physico-chemical analysis of chemical components of traditional Chinese medicine is insufficient to reflect the characteristics and mechanisms, the multi-target biological system correlation analysis in conformity to the holistic view of the basic theory of traditional Chinese medicine has gradually attracted wide attention. Specifically, bile acids, as an important endogenous metabolite in the body, play an important role in regulating digestion, absorption and metabolism of nutrients, and greatly impact the health. In recent years, a number of studies have been made on the metabolism pathway of bile acids and their important regulatory effects in body metabolism, making bile acids as a significant target of traditional Chinese medicine on the body. In view of this, based on bile acid metabolism, the paper reviewed the biological functions of bile acids in regulating body metabolism and its interaction with intestinal microbiota, providing a basis for exploring the connotation of bile acid metabolism changes under physiological/pathological conditions of the body. The study progress of bile acid metabolism in traditional Chinese medicine efficacy/toxic mechanism is further reviewed, which provides a basis for exploring the efficacy and hepatotoxicity mechanism of traditional Chinese medicine with bile acid as a biomarker, thereby laying a foundation for the clinical safety of traditional Chinese medicine.
