For this, Tribulus terrestris is one of the preferred herbal aphrodisiacs. [1] The use of Tribulus terrestris is not limited to India, as the medicinal plant has been a staple of traditional and folk medicine in Turkey, China, and other countries. Used to enhance energy, stamina, and sexual function, Tribulus is believed to stimulate the libido and support healthy testosterone levels. How Does Tribulus Terrestris Work?

Tribulus contains a compound called protodioscin. Protodioscin is a precursor to testosterone production and is also thought to dilate blood vessels. Dilated blood vessels allow for greater blood flow. When more blood is able to reach the penis, more healthy and full erections may result. Many animal studies involving Tribulus terrestris have repeatedly demonstrated its ability to increase testosterone levels and reduce the occurrence of impotence.
