Tribulus terrestris, also known as bindii, is an annual plant that grows in dry climates. It is commonly used to help improve athletic performance, infertility and loss of libido. This supplement is also backed by some science. Animal studies report increased sperm production in rats given Tribulus supplements.
Another study found 88% of women with sexual dysfunction experienced increased sexual satisfaction after taking 250 mg of Tribulus per day for 90 days. Additionally, a group of researchers examined the effect of Tribulus in women with sexual dysfunction by giving them 7.5 mg of the extract per day.
After four weeks, the women given Tribulus reported significantly higher levels of desire, arousal, lubrication and orgasm satisfaction. That said, more research is needed to evaluate optimal dosing, as well as the effects of Tribulus supplements in men.
The Tribulus terrestris plant may have aphrodisiac effects in women. More research is needed to evaluate optimal doses of Tribulus, as well as its effects in men.
