What it is
The herb Tribulus terrestris, also referred to as puncture vine, has been used by some athletes to encourage muscle growth by raising testosterone levels. Tribulus terrestris is also used to treat colic, lower blood pressure and increase libido in men and women. In some tests, the herb has demonstrated ability to lower blood pressure through lowering high cholesterol levels in the bloodstream. The only noted side effects are stomach upset, which can be prevented through taking the supplement with a meal.
Bodybuilding impact
Tribulus terrestris is used as an all-natural herbal supplement that is considered to be an alternative to synthetic anabolic hormones used by some bodybuilders. Tribulus terrestris works by releasing a luteinizing hormone, which triggers testosterone production. The production of testosterone creates protein synthesis and positive nitrogen balance, which promotes muscle cell growth and increased strength. It also is used to promote faster recuperation by the body from muscular stress. There is a diuretic effect that helps promote leaner muscle tissue as well. The herb was used by some Belgian weightlifting teams, and users of the Tribulus terrestris supplement report both significant increases in body muscle mass and shorter recovery time from workouts. Dieters and over-trained athletes have used the supplement to help restore depleted testosterone levels.
Test results
According to an abstract published on the PubMed website (www.pubmed.gov), a study was performed to investigate the effects of Tribulus terrestris on young men aged 20-36. After a four-week trial between three distinct groups (two control groups and one group receiving a placebo), testosterone and androgen production did not show any significant increase. Findings published on Supplement Genius' website (www.supplementgenius.com) are consistent with that conclusion.
Origins
Tribulus terrestris grows primarily in India and Africa and can also be found in tropical areas in the Americas, Asia, the Mediterranean and Australia. This vine is hardy enough to grow in some desert regions of the United States, where it is considered an invasive plant species. The Latin name translates to "thistle of the earth" and refers to a spiny fruit born by this trailing vine that is sharp enough to puncture the skin. In folk medicine Tribulus terrestris is used to treat a number of maladies, including male impotence, cardiovascular disease, and kidney problems. It is believed by some to stimulate the libido in both men and women, partly due to the production of testosterone and primarily due to the lowering of blood pressure and increased blow flow in the genitalia of both sexes. Tribulus terrestris is also believed to stimulate urine flow due to its diuretic properties and thus is considered beneficial for kidney function. There are antiseptic properties to Tribulus terrestris that can relieve kidney infections and urinary discharges.
