Abstract: In recent years, regulating bile acid metabolism to improve metabolic homeostasis has become an emerging research hotspot in the field of obesity prevention and treatment. Traditional Chinese medicine (TCM) active components (such as saponins, polysaccharides, flavonoids, and alkaloids) can influence bile acid metabolism through various pathways. Based on this, this article systematically reviews the recent research progress on the anti-obesity effects of TCM through regulating bile acid metabolism, aiming to provide a basis for subsequent clinical validation and offer new TCM strategies for the prevention and treatment of metabolic diseases.
