Tribulus Terrestris

Female sexual dysfunction

  • In 2014 DARU Journal of Pharmaceutical Sciences published a double-blind, placebo-controlled study in which 60 women with low sexual desire were given either a placebo or 7.5 mg/day Tribulus terrestris extract for 4 weeks. At the end of the 4th week the 30 women in the Tribulus terrestris group experienced greater improvements in desire, arousal, lubrication, satisfaction and pain.
  • In 2014 Clinical Medical Insights: Women’s Health published a 144-patient study which found that 250 mg per day Tribulus terrestris improved sexual function scores in 88 percent of women experiencing sexual dysfunction.

Erectile dysfunction

  • In 2017 Maturitas published a double-blind, placebo-controlled study of 172 males with mild-to-moderate erectile dysfunction. After 12 weeks 500mg Tribulus terrestris taken 3 times daily lead to greater improvements in intercourse satisfaction, orgasmic function and sexual desire when compared to a placebo.
  • In 2008 Phytomedicine published an animal study which found that Tribulus terrestris increased the levels of testosterone and other hormones involved in sexual function. The authors of the study concluded that Tribulus terrestris may be useful in mild to moderate cases of erectile dysfunction.


  • In 2012 the Journal of Pharmacology & Pharmacotherapeutics published an animal study which found that Tribulus terrestris dose-dependently increased sexual behavior in rats. Chronic administration also increased testosterone levels with no toxic effects observed.
