Origin of this essential oil, the tea tree, Melaleuca alternifoliaTea tree plantation, Coraki, New South Wales
Tea tree oil, also known as melaleuca oil, is an essential oil with a fresh, camphoraceous odor and a colour that ranges from pale yellow to nearly colourless and clear.[1][2] It is derived from the leaves of the tea tree, Melaleuca alternifolia, native to southeast Queensland and the northeast coast of New South Wales, Australia. The oil comprises many constituent chemicals, and its composition changes if it is exposed to air and oxidizes. Commercial use of tea tree oil began in the 1920s, pioneered by the entrepreneur Arthur Penfold.
There is little evidence for the effectiveness of tea tree oil in treating mite-infected crusting of eyelids,[3] although some claims of efficacy exist.[4][5] In traditional medicine, it may be applied topically in low concentrations for skin diseases, although there is little evidence for efficacy.[2][6][7][8]
Tea tree oil is neither a patented product nor an approved drug in the United States,[2][8] although it is approved as a complementary medicine for aromatherapy in Australia.[9] It is poisonous if consumed by mouth and is unsafe for children.[10]
