Sesame (/ˈsɛsəmiː/; Sesamum indicum) is a flowering plant in the genus Sesamum, also called benne. Numerous wild relatives occur in Africa and a smaller number in India. It is widely naturalized in tropical regions around the world and is cultivated for its edible seeds, which grow in pods or "buns". The world harvested 6.2 million metric tonnes of sesame seeds in 2014, with Tanzania, India, and Sudan as the largest producers. Sesame seed is one of the oldest oilseed crops known, domesticated well over 3000 years ago. Sesamum has many other species, most being wild and native to sub-Saharan Africa. Sesamum indicum, the cultivated type, originated in India and is tolerant to drought-like conditions, growing where other crops fail.
