Research Progress of Anti-tumor Effects of Curcuma zedoaria and its Active Ingredients Through Immune Regulation Mechanism

The continuous increase in the incidence rate of various fatal malignant tumors in the recent years warrants an imperative search for medications or drugs with obvious anti-tumor effects and reliable curative effects. Previous studies have found that Curcuma zedoaria and its active ingredients, such as turmeric oil, curcumol, and ?-elemene, have obvious anti-tumor effects, and they do not have the adverse reactions and side effects seen in the anti-tumor drugs of Western medicine. Based on the review and inductive analysis of related literature, we summarize in the present article the results of some researchers who investigated the anti-tumor effects of Curcuma zedoaria and its active ingredients through the immune regulation mechanism.
