Maca (Lepidium meyenii) is a hardy Andean root crop in the mustard family (Brassicaceae), grown above 4,000 m (13,000 ft) on the Peruvian high plateau. The fleshy underground storage organ — turnip-like and roughly 3–6 cm across — is dried and milled into a pale, malty powder marketed worldwide as a "superfood" and traditional restorative.
