[A mini-review on anti-tumor effect of cannabidiol].

Cannabidiol is the main non-psychoactive component of Cannabis sativa, which has multiple medicinal activities, such as antiepileptic, immunomodulation, analgesic, antioxidant, anticonvulsant, anti-anxiety and other functions. In recent years, it has been found that cannabidiol can inhibit the proliferation of various tumor cells, induce apoptosis and autophagy of tumor cells, arrest cell cycle, interrupt invasion and metastasis of tumor cells, regulate tumor microenvironment, exert synergistic therapy with other chemotherapeutic drugs, and reduce the toxicity of chemotherapeutic drugs. However, its anti-tumor effect remains controversial and its application is limited. The study of microspheres, nano liposomes and other new drug delivery systems can improve the anti-tumor effect of cannabidiol. In this study, the anti-tumor mechanism and application of cannabidiol were summarized and discussed in order to provide inspirations for its further investigation and application.
