how does it work?

Used in traditional medicine in Indian and Chinese cultures, Tribulus has been shown to enhance sexual behavior by stimulating androgen receptors in the brain. The active chemical in Tribulus responsible for its sexual stimulation is speculated to be protodioscin (PTN), a steroidal saponin compound that has demonstrated pro-erectile effects in isolated tissues and aphrodisiac behaviors. In some studies, Tribulus extract has outperformed testosterone cypionate, a synthetic version of testosterone, in length of sexual activity and "staying power."

Tribulus Terrestris (fruit)

A taprooted herbaceous perennial plant from the family Zygophyllaceae that is native to warm temperate or tropical regions of southern Europe, southern Asia, parts of Africa, and Australia. Tribulus Terrestris is traditionally used in tonics in Indian Ayurveda practices by the name "gokshura/sarrata" as well as traditional Chinese medicine.
