Moringa, (Moringa oleifera), also called horseradish tree or drumstick tree, small deciduous tree (family Moringaceae) native to tropical Asia but also naturalized in Africa and tropical America. Flowers, pods, leaves, and even twigs are cooked and eaten. The leaves, which can also be eaten raw when young, are especially nutritious and are high in iron, potassium, and vitamin C. A horseradish- flavored condiment is prepared from the crushed roots. Ben oil, extracted from the seeds, is used by watchmakers and in cosmetics; perfume makers value it for its retention of scents.
