Tea Tree Oil
The leaves of tea tree or Melaleuca Alternifolia when crushed release essential oils of varying amounts and constituents. Extensively used in aromatherapy, the oil is so potent that it can be diluted up to many times its volume and yet retain the same effectiveness. Although the benefits of tea tree oil are numerous, for beauty treatments it has been found effective in skin and hair care.
 Why should I be aware of this?
Though tea tree oil has been used as a remedy for a variety of conditions, there is limited scientific research to definitively prove its effectiveness. Scientists are continuing to research the complete medical capabilities of tea tree oil.
However aborigines in Australia have used tea tree oil leaves for coughs, colds, cuts and sores. Laboratory studies show that tea tree oil “has activity against Methicillin Resistant Staphylococcus Aureus (MRSA). MRSA is also called the “hospital superbug” which attacks patients with wounds and depressed immune systems. MRSA cannot be treated with conventional antibiotics with the exception of Vancomycin. A recent study at East London University shows tea tree oil as “powerful alternative” to Vancomycin. Further studies on real patients are currently being undertaken as this is one of the most promising uses of tea tree oil.
