Ocimum Sanctum: An All-Round Treatment for Cancer?

Abstract

Background This review is a great route for future researchers on the topic of alternative medicine. The review goes in depth with respect to Ocimum sanctum and its proposed mechanism of action for different types of cancers. Primary study objective The primary objective of the study was to bring traditional therapy back, which can prove to be economically beneficial and may be helpful to many patients with cancer with few to no adverse events. Intervention Ocimum sanctum (OS), commonly known as Holy Basil or tulsi, is a very important medicinal herb in parts of India and Southeast Asia. OS has been found to lower blood pressure and cholesterol, reduce the risk for heart attacks and may also be effective for treating depression and anxiety. It also protects the body from prolonged physical exertion, ischemia, exposure to cold and excessive noise, but its anti-tumorigenic effect remains largely unexplored. A few studies have observed that extracts of OS have inflammatory, analgesic, antipyretic, antidiabetic, hepatoprotective, hypolipidemic, anti-stress, and immunomodulatory activities. A few cell culture and animal studies have also shown that some of its phytochemicals like eugenol, rosmarinic acid, apigenin, myretenal, luteolin, β-sitosterol and carnosic acid prevent chemical-induced skin, liver, oral and lung cancers and mediate these effects by increasing antioxidant activity, altering gene expression, inducing apoptosis and inhibiting angiogenesis and metastasis. They are also shown to prevent radiation-induced DNA damage. This review details the different chemoprotective and radioprotective properties of OS and also gives an idea for future research.
