Native to Australia, the malaleuca tree (Melaleuca alternifolia), from which tea tree oil is derived, is a hardy evergreen-type tree similar to a cypress which may grow to as tall as twenty feet. Traditionally the native people of Australia used it for a variety of personal care uses, especially for the health of skin and hair. Tea tree oil has been used as a cleanser for skin and hair, and its light, spicy aroma has been used for aromatherapy. * Not available for sale in Canada or EU.
