health benefits and uses of tea tree oil

Though its popularity only increased in recent times, it has already been traditionally used by the Australian aboriginal tribes for the treatment of various ailments such as cough, colds, eczema, and various skin ailments.

Research in the twentieth century has confirmed its medicinal properties, and now it is widely used in the treatment of different bacterial fungal and viral infections either alone or in combination with other oils or pharmaceutical agents. (1)

Tea tree oil should not be confused with the tea that you drink daily, which is actually obtained by brewing the leaves of the totally unrelated Camellia species. The name tea tree was given to the plant by the famous explorer Captain James Cook. When he and his crew landed in Botany Bay, Australia, in the 18th century, they made tea from the leaves of this plant to prevent scurvy, thus the name tea tree.

The Australian aboriginal people had been using it to treat wounds long before that. Australian soldiers were issued tea tree oil as an antiseptic during World War II. Almost every household in Australia has a bottle of tea tree oil.

Though about 100 chemical components are reported in tea tree oil, the major component is terpinen-4-ol, which is found to have medicinal properties. (1) Terpinen-4-ol exhibits antimicrobial and immune-boosting properties.
