Tea tree oil comes from the leaves of Melaleuca alternifolia, a small tree native to Queensland and New South Wales, Australia.
Although Melaleuca alternifolia is known as the tea tree, it should not be confused with the plant that produces leaves used to make black and green tea.
Tea tree oil has been used as a traditional medicine by Aborigines for centuries. These native Australians crush tea tree leaves to extract the oil, which is then inhaled to treat coughs and colds or applied directly to the skin for healing.
Today, tea tree oil is widely available as a 100% undiluted or "neat" oil. Diluted forms are also available, ranging from 5–50% strength in products designed for the skin.
Uses of tea tree oil:
gets rid of nail fungus
boost wound healing
treat athlete’s foot
banish mold on fruits and vegetables
