Q: I’ve read Tribulus terrestris is used for bodybuilding. Is this supported by research?

Q: Is Tribulus terrestris only beneficial for men?
A: No, it can also be useful for women. It has been shown to increase libido and sexual enjoyment in women with low sex drive as well. Its other known benefits can be useful to both women and men.

Q: Why is it called ‘puncture vine’?
A: The spikes of the dried fruit are super sharp, and can cut into bare feet if you walk on them, or even bicycle tires if you ride over them.

Q: What else is puncture vine known as?
A: It’s often referred to as goat head or cow hoof, as the little hard fruit has sharp spikes or spines that resemble hooves or horns.

Q: Where does Tribulus terrestris grow?
A: It is native to the warm temperate and tropical regions of southern Eurasia, Africa, North America and Australia. Though since it’s so hardy, it’s become invasive, travelling from California northward to the Okanagan Valley in British Columbia. It thrives in sandy soil, and along roadsides. Good reason to wear shoes when outdoors!
