{{Citation box
|text=Only cultivated. The native area is not definitely known; probably of tropical African origin (Madagascar, Ethiopia). Cultivated as a food crop in tropical Africa, India (Kerala, Tamil Nadu, Karnataka), Sri Lanka and SE Asia. The starchy, slightly aromatic tubers are eaten boiled or steamed, sometimes raw. Cooked leaves also eaten as a vegetable. Used as a medicinal plant against dysentery and eye diseases in parts of tropical Africa and regarded as a potential anti-cancerogen. Formerly widely grown in the drier parts of tropical Africa, but now replaced mostly by ''Solanum tuberosum, Manihot esculenta, Arachis hypogaea'', etc., despite of its nutritional quality and high capacity of yielding on soils of low fertility. Several cultivars differing in colour and size of the tubers can be distinguished.
