Findings

This review of 7 small studies found green tea extract (EGCG) showed promise in two specific areas: topical application worked about as well as antibiotics for reducing odor from serious wound infections and improved quality of life, and oral green tea reduced radiation-induced diarrhea in one study. However, results were mixed overall—only one study showed a small decrease in prostate cancer markers—so evidence is limited and inconsistent.
