Moringa oleifera is a short-lived, fast-growing, drought-resistant tree of the family Moringaceae, native to northern India and used extensively in South and Southeast Asia. Common names include moringa, drumstick tree (from the long, slender, triangular seed-pods), horseradish tree (from the taste of the roots, which resembles horseradish), ben tree (for its oil), or malunggay (as known in maritime or archipelagic areas in Asia).

It is widely cultivated for its young seed pods and leaves, used as vegetables and for traditional herbal medicine. It is also used for water purification.
