Tribulus terrestris" or puncture vine."Tribulus" is a genus of plants found in many warm regions. The best-known member is "T. terrestris" (puncture vine), a widespread weed and also the source of a
dietary supplement claimed to increase the body's naturaltestosterone levels and thereby improve male sexual performance and help build muscle. "T. terrestris" has consistently failed to increase testosterone levels in controlled studies.

[cite journal|author=Rogerson S, Riches CJ, Jennings C, Weatherby RP, Meir RA, Marshall-Gradisnik SM. |title=The Effect of Five Weeks of Tribulus terrestris Supplementation on Muscle Strength and Body Composition During Preseason Training in Elite Rugby League Players |journal= J Strength Cond Res |year=2007 |issue=2 |volume=21 |pages=348–53 |pmid =17530942 |doi=10.1519/R-18395.1 ] However, many supplement brands such as 4Ever Fit and InterACTIVE Nutrition sold products that combines various herbs with tribulus terrestis, which has been a debate whether the effects are true or false.Tribulus has been shown to enhance sexual behaviour in an animal model. [cite journal|author=Gauthaman K, Adaikan PG, Prasad RN. |title=Aphrodisiac properties of Tribulus Terrestris extract (Protodioscin) in normal and castrated rats |journal= Life Sci |year=2002 |issue=12 |volume=71 |pages=1385–96 |pmid =12127159 |doi=10.1016/S0024-3205(02)01858-1 ] It appears to do so by stimulating androgen receptors in the brain.
"Tribulus" species are perennial, but some grow as annuals in colder climates. The leaves are opposite and compound. The
flower s are perfect (hermaphroditic) and insect-pollinated, with fivefold symmetry. The ovary is divided into locules that are in turn divided by "false septa" (the latter distinguish "Tribulus" from other members of its family).Some body builders use "T. terrestris" as post cycle therapy or "PCT". After they've completed an anabolic-steroid cycle, they use it under the assumption that it will restore the body's natural testosterone levels.
Tribulus has a long history of use in the Ayurvedic and Unani systems of India. It is considered an aphrodisiac, diuretic, and nervine.
Some species are cultivated as
ornamental plant s in warm regions. Some, notably "T. cistoides, T. longipetalus, T. micrococcus,T. terrestris ," and "T. zeyheri", are consideredweed s.References
