An extract from the thunder god vine, long used in traditional Chinese medicine, reduces food intake and causes up to a 45% decrease in body weight in obese mice. The weight-loss compound, called Celastrol, produces its potent effects by enhancing the action of an appetite-suppressing hormone called leptin. The findings are an early indicator that Celastrol could be developed into a drug for the treatment of obesity.
