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. S. indicum, the cultivated type, originated in India and is tolerant to drought-like conditions, growing where other crops fail. Sesame has one of the highest oil contents of any seed. With a rich, nutty flavor, it is a common ingredient in cuisines across the world. Like other seeds and foods, it can trigger allergic reactions in some people.
