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'. World production in 2016 was 6.1 million tonnes, with Tanzania, Myanmar, 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. 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 nuts and foods, it can trigger allergic reactions in some people. Sesame seeds are sometimes sold with the seed coat removed (decorticated); this variety is often present on top of baked goods in many countries. The word 'sesame' is from Latin sesamum and Greek sēsamon; which in turn are derived from ancient Semitic languages, e.g., Akkadian šamaššamu. From these roots, words with the generalized meaning “oil, liquid fat” were derived. Sesame seed is considered to be the oldest oilseed crop known to humanity. The genus has many species, and most are wild. Most wild species of the genus Sesamum are native to sub-Saharan Africa. S. indicum, the cultivated type, originated in India. Archaeological remnants suggest Sesame was first domesticated in the Indian subcontinent dating to 5500 years ago.Charred remains of sesame recovered from archeological excavations have been dated to 3500-3050 BC. Fuller claims trading of sesame between Mesopotamia and the Indian subcontinent occurred by 2000 BC. Some reports claim sesame was cultivated in Egypt during the Ptolemaic period, while others suggest the New Kingdom. Records from Babylon and Assyria, dating about 4000 years ago, mention sesame. Egyptians called it sesemt, and it is included in the list of medicinal drugs in the scrolls of the Ebers Papyrus dated to be over 3600 years old. Archeological reports from Turkey indicate that sesame was grown and pressed to extract oil at least 2750 years ago in the empire of Urartu.
