Ben oil
Ben oil is pressed from the seeds of the Moringa oleifera, known variously as the horseradish tree, ben oil tree, or drumstick tree. The oil is characterized by an unusually long shelf life and a mild, but pleasant taste. The name of the oil is derived from the high quantity of behenic acid. The oil's components are:

Seeds offer a relatively high yield of 22-38% oil. Ben oil has been used for thousands of years as a perfume base, and continues to be used in the capacity today. The oil can also be used as a fuel. Burkill reports:
It burns with a clear light and without smoke. It is an excellent salad oil, and gives a good soap... It can be used for oiling machinery, and indeed has a reputation for this purpose as watch oil, but is now superseded by sperm oil.
