Tribulus terrestris, or puncture vine, is a plant that has been used in traditional Chinese and Indian medicine for centuries.  It has been utilized largely as a digestive aid and libido enhancer.  It became popular in North America during the mid 1990’s when it was brought into the spotlight from the eastern European competitors claiming that it boosted their athletic performance.  Since then, its reputation has been magnified as a natural cure for erectile dysfunction and other ailments due to its reported ability to rebalance testosterone levels.

Most species of Tribulus are perennials. However in colder climates, some grow as annuals. The leaves of all Tribulus species are compound and opposite.  The insect-pollinated flowers of the Tribulus plants are hermaphroditic displaying five-fold symmetry.  Some species of Tribulus, especially in warmer climates, are cultivated as ornamental plants.  Other species, including puncture vine, are classified as weeds.

Animal modeling has shown Tribulus terrestris to be effective in enlivening sexual behavior.  This is believed to be true due to its ability to stimulate androgen receptors in the brain. Human studies have failed to show the same, but its popularity continues to grow.  It is believed to promote overall health, aid digestion, support healthy cholesterol levels, maintain balanced blood pressure readings, enhance libido function and increase muscle tone.  While clinical studies have not proven the purported benefits of puncture vine.
