Kusum oil is a type of oil extracted from the seed of the Kusum tree (Schleichera oleosa). The plant, which is also commonly known as Ceylon oak, lac tree, or Macassar oiltree, belongs to the Sapindaceae family. The schleichera family is named after J. C. Schleicher, a Swiss botanist, and the species name means "oily" or "rich in oil." The tree is native to India and Pakistan, but is also found in some parts of Southeast Asia.

Oil
The oil contains oleic acid (2-3%), Stearic acid (2-6%), Gadoleic acid and arachidic acid as well as cyanogenic compounds, which must be removed for human consumption. Kusum oil is unusual, with just 37% of common glycerol esters. The oil also contains Linoleic acid (43-50%), Palmitic acid (5-8%), and hydrocyanic acid, which is poisonous and must also be removed prior to consumption. The oil is yellowish brown, semi-solid, with the faint odour of bitter almond. When allowed to settle, a light coloured solid fat separates. Kusum oil contains a cyanogenic compound in concentration of 0.03-0.05% as HCN. But the exact location of the cyanogenic compound in the oil or its nature has not been reported.
