Australia is home to more than 700 types of fast-growing, flowering evergreens known as eucalyptus. Part of the myrtle family (Myrtaceae), these plants can grow to 60 feet tall and 15 feet wide. doTERRA has selected five unique species to create its proprietary Eucalyptus: Eucalyptus radiata, Eucalyptus polybractea, Eucalyptus kochii, Eucalyptus loxophleba, and Eucalyptus globulus. The primary chemical component of these species is eucalyptol (1,8-Cineole), which is where this essential oil blend gets many of its benefits. The camphoraceous, herbaceous aroma can be revitalizing. Due to the oil’s main constituent, 1,8 cineole, Eucalyptus essential oil also has cleansing properties. Use aromatically or topically to promote feelings of clear breathing and open airways. Eucalyptus essential oil also adds to a soothing massage.
