Abstract: Epimedii Folium is a traditional non-toxic Chinese herbal medicine. However, liver injury caused by Chinese herb preparations, including Epimedii Folium, is frequently reported over the years. Based on ancient and modern literature, this paper systematically summarized and analyzed the safe application of Epimedii Folium from the perspectives of varieties, processing methods, clinical adverse reactions, pharmacological effects and toxic mechanism. Combined with our team work, we build the comprehensive prevention and control system "human-drug-application", for the safe and rational application of Epimedii Folium. This study is expected to provide support for scientific evaluation and precise prevention and control of the safety risk of Epimedii Folium.
