Sesame oil (Gingelly oil, Teel oil) is obtained by refining the expressed or extracted oil from the seeds of Sesamum indicum L. (Pedaliaceae), a herb which is widely cultivated in Middle East, India, China, Japan and many tropical countries. The oil is official in the EP and BP.

The seeds contain about 50% of fixed oil which closely resembles olive oil in its properties and which it has, in some measure, replaced. It is a pale yellow, bland oil which on cooling to about −4°C solidifies to a buttery mass; it has a saponification value the same as that for olive oil and a somewhat higher iodine value (104–120).
