Oil Geographical scope
Cashew oil refers to oil extracted from the fruit of the cashew. The cashew nut has a shell with an oily outer layer, and a hard inner layer, within which the familiar cashew nut is contained.
Cashew shell oil comes from the outer shell. It is toxic to humans, and is normally considered a waste product. Some work, however, showed that cashew shell oil can be useful in fighting dental cavities.
