An essential oil obtained from the dry leaves of several species of Eucalyptus trees (especially E. salicifolia, E. Dives and E. globulus) and each type of tree produces a slightly different composition. Most eucalyptus oils contain cineole as the primary component. Cineole is a water-insoluble liquid that has a camphor-like odor. Eucalyptus oil is also used for leather conditioning, as a textile lubricant, as a synthetic sperm oil, as an insect repellent and as a cleaner/deodorizer. Small amounts of the oil are added to cough drops and decongestants.
