Eucalyptus globulus is native to Australia and is known as the gum tree. Nearly all Eucalyptus are evergreen. Eucalyptus globulus leaves are covered with oil glands, and the oils produced are an important feature of the tree. The leaves also contain flavonoids and tannins; flavonoids are plant-based anti-oxidants, and tannins may help to reduce inflammation.

The Aborigines have used Eucalyptus globulus for centuries for timber, tinder, and medical purposes. It is used to reduce symptoms of coughs, colds, and congestion. It also features creams and ointments aimed at relieving muscle and joint pain. Eucalyptus globulus has a useful aromatic oil that can be extracted through steam distillation. The oil has been used for anti-septic, anti-bacterial, and anti-inflammatory.
