Rosemary (Rosmarinus officinalis L.) has been found to possess antitumor effects due to its major ingredients, including carnosic acid, carnosol, ursolic acid, and rosmarinic acid. Objective: This study was designed to gather the recent literature findings from 2010 to 2016 on the cancer anti-tumor activities of carnosol and probably involved mechanisms. Method: The online English papers were gathered through various search websites, including PubMed, Iran Medex, Medline, Google Scholar, and Scopus from 2010 to 2016. Results: Carnosol, the specific composition of rosemary, has been shown to have beneficial effects in keeping humans healthy and may be acted as an antitumor agent. Conclusion: This review revealed that carnosol may be effective as an anti-tumor agent in the different types of cancer by inducing apoptosis and inhibiting the cell cycle division. However, more studies are needed to confirm carnosol therapeutic effects in human.
