An essential oil obtained by steam distillation of the leaves of eucalyptus trees, which are native to Australia and belong to the Myrtaceae family. The main components vary depending on the type of eucalyptus, and are broadly divided into three types: cineole-based eucalyptus oil (containing more than 70% cineole), eucalyptus oil containing piperitone and phellandrene, and eucalyptus oil containing citronellal and geranyl acetate. It is mostly used medicinally, as an oral preparation, cough suppressant, disinfectant, and raw material for synthetic fragrances. Camphor white oil (containing cineole) is also used as artificial eucalyptus oil.
