NOW Tribulus 

Traditionally used in Ayurveda as a diuretic and aphrodisiac for men. Tribulus terrestris has been used for centuries in ancient Greece, India and Africa to enhance vitality and virility. Recent research indicates that Tribulus can support the body’s free radical defense systems and preliminary studies suggest that Tribulus may help to promote healthy endocrine function and male reproductive health.

Used in Ayurvedic medicine, tribulus has cooling, diuretic, tonic, and aphrodisiac properties, and is used in urinary disorders including painful urination, kidney and bladder stones, and impotence. Traditionally, it has been used for a variety of reproductive conditions, such as infertility and impotence, as well as for muscle strength and general health. Protodioscin is a phytochemical agent derived from Tribulus terrestris L plant, which has been clinically proven to improve sexual desire and enhance erection via the conversion of protodioscine to DHEA (De-Hydro-Epi-Androsterone).
