Maca is a root vegetable that grows in the mineral-rich volcanic soil of the Peruvian highlands. Up at 15,000 feet, few plants can endure the hot days and cold nights, but maca thrives in these conditions and therefore has all the mineral-rich soil to itself. As with any plant, maca is simply a medium for the nutrients found in the soil, passing them on to the eater of the plant. And since low mineral content can cause hormones to become unbalanced, maca can bring them back. Known as an adaptogen, maca will help bring down cortisol. This will dramatically improve and increase sexual desire.
