Abstract
Tribulus terrestris (caltrop) is a flowering plant of the family Zygophyllaceae. Tribulus terrestris has long been used in the traditional Chinese and Indian medicine for the treatment of various ailments.
Lately, it’s one of the most discussed herbs. Studies on the constituents of Tribulus terrestris led to the isolation of many biologically active compounds: steroidal saponins of furostanol and spirostanol type, flavonoids and phytosterols, alkaloids, organic acids, amino acids and carbohydrates.
It has been shown that the active substances exhibit antimicrobial, antioxidant, diuretic, hypotensive and antidiabetic activity. All tests have also shown that biologically active substances show significant effects on the reproductive system.
These effects on the reproductive system were verified in a large number of animal studies, studies in humans are not many, but also confirm these effects.
