This study was based on the scientific questions of Dihuangye (Rehmanniae Folium), including the unclear history of the medicine property and functions, the similarity and difference of chemical components in the folium and root of Dihuang (Rehmannia glutinosa), the correlation between chemical compositions, pharmacological actions and medicinal property, functions of Dihuangye (Rehmanniae Folium) . Adopting literature analytic methods, the historical evolution of medicine property and functions of Dihuangye (Rehmanniae Folium) was clarified, and their basis and scientificity were discussed. The chemical compositions and pharmacological effects of Dihuangye (Rehmanniae Folium) were systematically studied, the similarities and differences of the chemical components between Dihuangye (Rehmanniae Folium) and Dihuang (Rehmanniae Radix) were compared, and the correlation between the chemical compositions, pharmacological effects and medicine property, functions of Dihuangye (Rehmanniae Folium) was clarified.
