Melaleuca alternifolia is notable for its essential oil, which has antifungal and antibiotic properties in vitro. [30] [31] Though it is safe for topical applications, [32] tea tree oil is toxic if ingested orally. [30] The oil is produced on a commercial scale and marketed as tea tree oil. [33]
The oil is produced by steam distillation of the M. leucadendra and M. quinquenervia species. A similar essential oil known as tea-tree oil is extracted from the species M. alternifolia, a native of Australia. Melaleuca pollen can be an allergen and tea-tree oil may cause allergic reactions for some people. [5]
