Alternative Treatments for Weight Loss: Safety/Risks and Effectiveness of Anti-Obesity Medicinal Plants

Abstract

Obesity is emerging globally as a leading, underlying contributor to a variety of different diseases, some of which are fatal. This study aims to provide a brief review of the botanical sources which are available to serve as an alternative to modern, synthetic anti-obesity drugs, and to provide a brief discussion of their mechanism of action, and their safe and effective usage. Information was gathered from books, journals, and a variety of electronic sources published in the period of 1991 to 2014. Medicinal plants can reduce weight through five basic mechanisms: controlling appetite, stimulating thermogenesis and lipid metabolism, inhibiting pancreatic lipase activity, preventing adipogenesis, and promoting lipolysis. Based on a review of the available literature, the consumption of recommended medicinal plants in a single form, and at an optimum dosage, could be a safe and effective complementary treatment for obesity.
