It has been in medical use in treating several conditions due to its antimicrobial properties. When applied topically, it helps fight skin conditions such as lice, acne, dandruff, fungal infections, ear infections, vaginal infections, toothaches, and herpes among others.

Where does it Come from?

Tea tree oil is derived from the leaves of a native plant to Southeast Queensland and the Northeast Coast called melaleuca alternifolia. Its name came from eighteenth century sailors from the swampy southeast Australia coast who prepared tea with a nutmeg scent from the leaves of the tea tree. It has also been used for hundreds of years in treating insect bites and sore throat. Some people use it to treat* bronchial congestion, pulmonary inflammation and cough by adding it to bath water.

Uses of Tea Tree Oil in Supplements
