Tea Tree Oil Tea tree oil is an essential oil that can be used for several purposes, including keeping skin, hair and nails healthy. In addition to its scientifically backed benefits, tea tree oil is inexpensive and safe when used as directed. This article discusses 14 everyday uses for tea tree oil and provides guidance on using it safely and effectively. 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, green and oolong 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. Tea tree oil contains a number of compounds, including terpinen-4-ol, that have been shown to kill certain bacteria, viruses and fungi (1, 2). Terpinen-4-ol also appears to increase the activity of your white blood cells, which help fight germs and other foreign invaders (3). These germ-fighting properties make tea tree oil a valued natural remedy for treating bacterial and fungal skin conditions, preventing infection and promoting healing. Read on to learn about the many uses and benefits of this versatile oil.
