Tea Tree Oil African is steam-distilled from the leaves of the Melaleuca Alternifolia tree, which is native to Australia but has since expanded to many other regions of the world. The aroma of this oil is warm and spicy, with a fresh and camphoraceous top note that retains an interesting slight bitterness. Historically, tea tree oil has served as an antiseptic ingredient for many cultures, earning it a unique reputation among health-related circles. In perfumery, this angle rarely if ever comes into effect, though the pleasant warm-spicy odor of tea tree has gained significant popularity among the cosmetics industry. Tea tree oil is of particular interest within masculine items, such as colognes and aftershaves, where its spiciness blends exceptionally well alongside ingredients like rosemary, clove, and oakmoss.
