Maca root is a Peruvian herb indigenous to the Andes mountains. It was revered by ancient Incan culture for its ability to boost libido as well as to enhance energy and mental clarity, according to WebMD.
There is some limited scientific evidence to support the notion that maca root helps to increase libido, according to WebMD. However, in the absence of more randomized control studies, many scientists remain skeptical that maca's libido-enhancing effects are, in fact, substantiated.
Maca root is classified as a starchy tuber, which resembles a radish, but many say it tastes more like a potato. Maca is typically consumed baked or roasted, as an ingredient in soups, or as a supplement added to drinks or smoothies.
