Tribulus terrestris is an annual plant in the Caltrop Family (Zygophyllaceae) widely distributed around the world, that is adapted to grow in dry climate locations in which few other plants can survive.It is an invasive species in North America.ne study found that administration of Tribulus terrestris extract can produce statistically significant increases in levels of testosterone, dihydrotestosterone and dehydroepiandrosterone, and produces effects suggestive of aphrodisiac activity.
Tribulus is an all natural product and studies on humans have shown no side effects. The product is safe for use by women and men. Toxic effects have been observed in sheep fed large amounts of Tribulus [1], but are not likely to be applicable to normal supplemental use by humans. Back to top.
