[Research progress of liver injury induced by Polygoni Mulitiflori Radix].

Polygoni Mulitiflori Radix, or dried root tuber of Polygonum multiflorum(PM), is a traditional Chinese tonic medicine, with the effect in nourishing liver and kidney, and benefiting blood essence and hair. It is widely used in clinical and healthcare products. In recent years, more and more reports about adverse reactions of root tuber of P.multiflorum and its preparations have been reported. Fortunately, there is also substantial progress in the experimental study on liver injury induced by PM. According to the literature review, the possible causes of liver injury were found to be the mixture of raw and processed PM and long-term high-dose administration. In addition, the liver injury induced by PM is idiosyncratic liver injury, and individual factors are also the important cause. At the same time, according to the literature reports, the effects of chemical components in different pathological animal models were summarized, finding that 2,3,5,4'-tetrahydroxystilbene-2-O-β-D-glucoside was the main component for liver injury; based on the clinical manifestations of liver injury induced by PM, the effects of some chemical components on bilirubin and bile acid metabolism were analyzed. This paper reviews the study progress of liver injury induced by PM.
