Tribulus – aphrodisiac for males

Tribulus aka puncture vine is a supplement made by Metagenics www.DrJeffreyTucker.meta-ehealth.com . Tribulus has traditionally been used (literally for more than 1000 years) as an aphrodisiac for males.  It has recently been used as a performance enhancer by some former Eastern block countries.  While the mechanism is not really known, it is felt that tribulus decreases testosterone clearance as opposed to directly stimulating its production.  Ashwagandha, also referred to as “Indian Ginseng,” has also been traditionally used as a “tonic” for men.  Finally, cowage/mucuna contains natural L-dopa, a side-effect of which is spontaneous erection.

 Thus, the rationale for using Tribulus Synergy is more philosophical and in line with the traditional use of these herbs contained in the formula.  While Tribulus has very controversial documentation in western literature, it is one of the oldest herbs in Traditional Chinese Medicine and is well respected in that circle.

“… In castrated rats, increases in [testosterone] levels by 51% and 25% were observed with [testosterone] and [tribulus] extract respectively that were statistically significant. [Tribulus] increases some of the sex hormones, possibly due to the presence of protodioscin in the extract. [Tribulus] may be useful in mild to moderate cases of ED…” Phytomedicine. 2008 Jan;15(1-2):44-54.
