What Is Tea Tree Oil?
Tea tree oil is obtained from Melaleuca alternifolia, a plant native to Australia. The plant has a long history of traditional topical use for skin-related applications.
Tea tree oil is more commonly used in cosmetics than the corresponding extract and is valued primarily for its skin-conditioning and antimicrobial properties.

Historical Use
Tea tree was described in detail during the expeditions of Captain James Cook in the late 1700s. The plant subsequently became well known for traditional applications involving skin ailments, cuts, and burns.
During World War II, tea tree preparations were also used as topical antiseptics before being replaced by more effective antimicrobial agents.
