Eucalyptus oil is primarily extracted from the leaves of the evergreen tree, eucalyptus globulus or the Tasmanian bluegum, southern blue-gum and sometimes called as fever tree. This aromatic essential oil can be used as an antiseptic, for deodorizing, and occasionally in food supplements, particularly sweets, medicated lozenges, used to soothe the throat, toothpaste and in drugs that decreases pulmonary congestion. It has insectifuge properties as well and used as an important component in many commercial mosquito repellents.
