Ingestion of G.atroviridis tea is expected to protect from oxidative stress. The aim of the this study was to evaluate the antioxidative benefit of G.atroviridis leaf tea on malondialdehyde levels of obese adults. This research recruited fifteen obese adults. All of the subjects were given G.atroviridis tea for a month. As a result, current study obtained statistically nonsignificant differences of post-test malondialdehyde levels compared with pre-test levels among all subjects. It can be concluded that G.atroviridis tea taken once daily for 30 days was not sufficient to decrease MDA levels significantly. Although anthropometric measures decreased significantly, the subjects were still in the criteria of obesity. In addition, the lifestyle factors that increases MDA should be avoided.
