This energizing plant is also referred to as Peruvian ginseng (although maca is not in the same family as ginseng, it is actually closely related to the radish). Maca has a folklore reputation as an aphrodisiac and fertility enhancer and has been used for centuries in the Andes, where it thrives on the glaciated slopes of the Andes with a prime elevation of 12,000 to 15,000 feet above sea level.

Maca is a natural source of amino acid argentine, which is thought to assist in the generation of nitric oxide that helps counteract male impotence. Many libido- and sexual-enhancement health supplements on the market today contain argentine for this reason (although this is not clinically validated). The synergy of so many amino acids, vitamins, and minerals in their natural states may increase the assimilation, uptake, and utilization of them in the body makes maca a good source of energy and nutrition. Maca root is being effectively administered to both men and women to help increase libido, men's sperm activity, and to assist both sexes with issues regarding their physical endurance and threshold.

Not much research has been carried out for this particular botanical out of its native country Peru, but several distinguished journals and scientists worldwide have supported what the Peruvian researchers have done and the preliminary studies they published.
