Anticancer, chemopreventive and radioprotective potential of black plum (Eugenia jambolana lam.).

Abstract

Despite good understanding of the molecular basis of the disease and advances in treatment, globally cancer is still a major cause of death. Estimates are that it will surpass cardiovascular disease as the leading cause of death, with higher incidences in the developing countries that have minimal resources. Chemotherapy and radiotherapy, the two most commonly used treatment modalities, are associated with untoward side effects. This has necessitated the search for alternatives that are effective, non toxic and easily affordable for patients and traditional medicinal plants are an ideal source. Eugenia jambolana Lam., commonly known as black plum or 'jamun' is an important medicinal plant in various traditional systems of medicine. It is effective in the treatment of diabetes mellitus, inflammation, ulcers and diarrhea and preclinical studies have also shown it to possess antineoplastic, chemopreventive and radioprotective properties. Here, for the first time, the effects of jamun in treatment and prevention of cancer, and the mechanisms responsible for these effects are appraised. Additionally the drawbacks in existing knowledge are also stressed to emphasize the possible avenues that need to be investigated, so that maximum effects on both prevention and cure can be attained.
