The oil is prepared from leaves collected on a hot dry day, macerated in water, and distilled after fermenting for a night. This oil is extremely pungent, and has the odor of a mixture of turpentine and camphor. It consists mainly of cineol (see terpenes), from which cajuputene, having a hyacinth-like odor, can be obtained by distillation with phosphorus pentoxide. It is a typical volatile oil, and is used internally in doses of 2 to 3 minims, for the same purposes as, say, clove oil. It is frequently employed externally as a counterirritant. It is an ingredient in some liniments for sore muscles such as Tiger Balm and Indonesian traditional medicine .
