Tribulus terrestris is an ingredient commonly found in dietary supplements that are used for enhancing sexual function and improving athletic performance. Research shows that the flowering plant may have diuretic effects and could increase the level of various hormones (including testosterone). Some people may be more likely to experience problems with Tribulus terrestris than others; you should talk with your healthcare provider prior to taking the supplement if you have an enlarged prostate, prostate cancer, or diabetes.
