Ulcer
Papaya leaf tea protected against gastric ulcer in a study on laboratory animals published in the September 2008 issue of the "West Indian Medical Journal." In the study, papaya leaf extract reduced ulcer severity and showed strong antioxidant effects. Papaya leaf extract also decreased oxidized lipids and increased antioxidant activity within red blood cells. Researchers concluded from this preliminary study that papaya leaf tea shows potential for the treatment of gastric ulcer and oxidative stress on the stomach.
