Lepidium meyenii

Lepidium meyenii, known as maca or Peruvian ginseng, is an edible herbaceous biennial plant of the family Brassicaceae that is native to South America in the high Andes mountains of Peru and Bolivia. Its use increased after the late 1980s, when it was commercially discovered. It is grown for its fleshy hypocotyl that is fused with a taproot, which is typically dried but may also be freshly cooked as a root vegetable. As a cash crop, it is primarily exported as a powder that may be raw or processed further as a gelatinized starch or as an extract. If dried, it may be processed into a flour for baking or as a dietary supplement.
