Eucalyptus globulus is an evergreen tree native to Australia with leathery, aromatic, blue-green leaves. Eucalyptus is very fast growing and can reach towering heights. For thousands of years, Australian aborigines used eucalyptus leaf for its healthful properties. Eucalyptus leaves are typically taken as a tea or tincture and can also be used in topical applications. The eucalyptus is an evergreen tree native to Australia but naturalized to California and the Mediterranean countries. Its leathery blue-green leaves are studded with glands containing a fragrant, volatile oil. There are many species of eucalyptus trees, but the most pleasant-smelling oil is produced by Eucalyptus globulus. Typical preparations include facial or hydro-steams, aromatherapy, and teas. Some uses may include encapsulation or extracts, however we have found these to be rare. Eucalyptus oil acts on nerve receptors in the mucosa of the nose and sinuses in a way that causes release of mucus. Eucalyptus belongs to the Myrtaceae family and also goes by the name ribbon gum and shining gum.
