Tea Tree Oil

Tea tree oil is the essential oil steam distilled from the Australian plant Melaleuca alternifolia. This species is unique to Australia and native to Northern New South Wales. Tea tree oil contains over 100 components, mostly monoterpenes, sesquiterpenes and their alcohols.  Terpinen-4-ol is present at the highest levels (minimum 30%) and is responsible for most of the antimicrobial activity.


Tea tree oil is a natural antifungal, antibacterial, antiviral, anti-infection oil. It is effective against nail fungus, ringworm, athlete's foot, dandruff, acne and many types of infestations including lice, mites and scabies.

Tree oil is not just soothing and disinfecting, it is capable of penetrating into the lower skin layers with its anti-inflammatory, disinfectant, analgesic (pain killing) and cicatrizant (wound-healing) qualities. It helps the skin to heal by encouraging the formation of scar tissue.

People with sensitive skin should introduce the oil with caution. Tea tree oil is not to be taken internally except as a mouthwash or gargle as directed
(do not swallow).

Tea tree has a long history of traditional use. Australian aboriginals used tea tree leaves for healing skin cuts and infections, by crushing the leaves and applying them to the affected area. The oil contains constituents called terpenoids, which kill fungus and bacteria.
