Guidelines for safe use of Polygoni Multiflori Radix

Abstract

Polygoni Multiflori Radix (He Shou Wu) is a Chinese medicine widely used in clinical treatment and preventive healthcare. However, recently there have been frequent reports of liver injury caused by Polygoni Multiflori Radix and its related preparations, and some patients have serious adverse outcomes, attracting wide attention worldwide. The risk of liver damage caused by preparations containing Polygoni Multiflori Radix or Polygoni Multiflori Caulis has been repeatedly reported by the Chinese Food and Drug Administration. Fortunately, substantial progress has recently been made in revealing the basic properties, main causes, material basis, and molecular mechanism of Polygoni Multiflori Radix-related liver injury. The basic characteristics and biomarkers of susceptible people have been identified, indicating that Polygoni Multiflori Radix has the risk of inducing liver injury only in a few specific populations and is safe for most populations. This study provides a scientific basis for a correct and objective understanding of liver injury caused by Polygoni Multiflori Radix, and a reasonable formulation of safe medication measures for Polygoni Multiflori Radix and related preparations. The China Association of Chinese Medicine organized experts in relevant fields across the country to draft and formulate the “Guidelines for Safe Use of Polygoni Multiflori Radix” with the aim of helping the public and relevant institutions at home and abroad to scientifically understand, evaluate, and avoid the risk of liver injury; guide the rational use; protect the health rights and interests of consumers; and promote the healthy and sustainable development of Polygoni Multiflori Radix and related preparations. These guidelines were issued by the China Association of Chinese Medicine (No. T/CACM 1328-2019).
