Eucalyptus Globulus is also known as Blue Gum. It’s an evergreen tree commonly found in Australia, which grows from 30 to 55m tall with long narrow bluish-green leaves and white-yellow flowers. Eucalyptus leaves are the favourite food of Koalas, and have been used as traditional medicine by the aboriginal peoples of Australia. In the 1980s, the Eucalyptus species and its hybrids were planted commercially in South Africa for the production of pulp and paper, and various other forest products. It has slowly evolved toward the production of essential oils.
