Tea Tree Oil

Tea tree oil is a true miracle of nature — an essential oil, steam-distilled from the leaves of the Melaleuca alternifolia, which includes a variety of plants native to the southeastern area of Queensland and the northeastern coast of New South Wales in Australia. The oil has a fresh, camphor-like odor and a color ranging from pale yellow to clear.  (Wikipedia, 2014) It contains over 98 active compounds, is natural, green and sustainable.

Humans have found many topical uses for this miraculous natural substance. Often referred to as a “medicine cabinet in a bottle”, it stimulates the immune system and is effective against bacteria, fungi and viruses.  Although the indigenous Bundjalung of eastern Australia have used it for centuries to treat coughs, colds, sore throats and various skin ailments, science didn’t formally understand the oil’s antimicrobial properties until the 1920’s and 1930’s. 

Large-scale production began when commercial tea tree plantations were established in the 1970’s and 1980’s. (One Green Planet, 2012)

According to the Mayo Clinic:

“Allergic reactions have been reported with tea tree oil when taken by mouth or used on the skin. Skin reactions ranged from mild contact dermatitis (skin inflammation) to severe blistering rashes.

“Avoid in people with a known allergy or sensitivity to tea tree oil (Melaleuca alternifolia), to any of its parts, Balsam of Peru, benzoin, colophony (rosin) tinctures, eucalyptol, or to plants that are members of the myrtle (Myrtaceae) family.

 “Tea tree oil is likely safe when applied to the skin in recommended doses and durations in non-allergic people.”

 They go on to list many possible side effects and warnings and discuss its safety during pregnancy and breastfeeding. This is the Mayo Clinic’s full list of warnings, dosing information and drug interactions.

 Yet, for the majority of people who are not allergic to it, availing themselves of tea tree oil’s many uses is highly beneficial – including ingesting it to produce a Candida albicans (yeast infection) die off, adding it to neti pots to vanquish sinus infections and using it as a mouthwash.
