Tribulus Terrestris refers to an herb used in India and China as traditional medicines for centuries. Tribulus Terrestris contains active compounds known as steroidal saponins, and these are basically found in the leaf. The tribulus consists of furostanol and spirostanol glycosides. People use Tribulus Terrestris for erectile dysfunction as well as low libido. This has gained popularity owing to sports performance improvement. This is available in Russia and Bulgaria as it enhances the testosterone hormone levels, estrogen and DHEA. Tribulus Terrestris supplements taken for four weeks showed no effect on the hormones of the male sex. Preliminary studies heightened the sexual behavior in animals and yet the studies have not confirmed its effect on human beings. However, Tribulus is popular as an aid for sports performance as it shows no effect in exercise performance or body composition. Tribulus do not show any significant change in fat or body weight and this difference can be felt by experiencing strength in the leg press. Conversely, nursing or pregnant women should avoid taking Tribulus.
