Tribulus (Tribulus terrestris)

Background
Tribulus terrestris has a long history of use for a variety of conditions. It has been suggested that it was used in ancient Greece and India as a physical rejuvenation tonic. In China, it is used as a component of therapy for conditions affecting the liver, kidney, cardiovascular system and immune systems. It has also been used in Eastern European folk medicine for increased muscle strength and sexual potency. Despite its history of use, there is limited human data available in order to evaluate its clinical effectiveness.
Tribulus has been studied as a non-steroidal alternative to treatment of infertility. Although the results of the few studies done with the combination product Tribestan® are promising, more studies are needed in order to further evaluate its clinical effectiveness. Preliminary research with tribulus also suggests that it may be useful in treating coronary heart disease, but additional study is needed.
