Tea Tree Oil: Health Benefits and Risks
Indigenous Australians have been using tea tree oil, which is made from the leaves of the Melaleuca alternifolia plant, as a traditional treatment for millennia. It has been more well-known worldwide in recent years as a natural remedy for various illnesses and skin disorders.
Tea tree oil is a multipurpose essential oil that is used in a variety of skincare products, shampoos, and household cleansers because of its strong antibacterial, anti-inflammatory, and antiseptic qualities. Like every natural cure, it has advantages as well as disadvantages. The advantages of tea tree oil supported by science, possible hazards, and safe usage will all be covered in the following article.
What Is Tea Tree Oil?
The leaves of the tea tree plant are steam-distilled to obtain the oil. Terpinen-4-ol is the most abundant of its more than 100 bioactive chemicals. A large portion of the antibacterial and anti-inflammatory properties of tea tree oil are attributed to this molecule. Because of its strength, the oil is usually diluted before usage and has a fresh, camphor-like aroma.
