Tribulusterrestris

1Tribulus has long been used in traditional Chinese medicine, as well as in ayurveda to enhance athletic performance or increase libido. Tribulus is also said to raise your levels of certain hormones, including testosterone and estrogen, and is found in supplements claiming to increase testosterone levels

2 Dietary supplements containing tribulus are often marketed for their potential to increase testosterone levels and, in turn, build muscle mass and boost strength. However, a report published in the Journal of Dietary Supplements in 2014 states that such marketing claims are unsubstantiated

3Tribulus may help treat erectile dysfunction, according to a study published in Maturitas in 2017.3 In testing the effects of 12 weeks of a tribulus extract on men with mild or moderate erectile dysfunction, researchers found that those who took tribulus had a significant improvement in sexual function (including erectile dysfunction).
