Only in the last decade has the Manuka tree begun to be recognized and understood through science, but the Maori (who are the indigenous people of New Zealand) have long known the strength and healing ability of the Manuka tree.Manuka has been used to treat a range of skin problems, including chronic sores, ring worm and eczema. Others reported that a decoction of Manuka leaves was drunk for urinary complaints and to reduce fever. The leaves were boiled in water and inhaled for head colds, blocked sinuses, hay fever, even bronchitis and asthma. Leaves and bark were boiled together, and the warm liquid was rubbed on stiff backs and rheumatic joints. The leaves and young branches were put into vapor baths. The crushed Manuka leaves were applied as a poultice for many skin diseases and were directly applied to wounds and deep gashes to enhance healing and reduce the risk of infection. The young shoots of the Manuka tree were chewed and swallowed for dysentery. The bark, the sap, and the seed capsules of the Manuka tree were also used extensively for treating various ailments.
Clearly, Manuka was an important medicinal plant, both to the Maori and to the original European settlers who, in the early years of settlement, depended on Maori knowledge of medicinal plants in treating their own illnesses.
Although the Manuka tree of New Zealand had attracted scientific interest in the past, little had been found of real importance - until some Manuka oil samples were tested by Dr. Cooke of the Cawthron Institute and showed some remarkable results.
The testing showed Manuka Oil to be active against a wide range of micro-organisms that cause irritation and infection of the skin and body. Some of them were serious, such as MRSA (antibiotic-resistant Staphylococcus aureus, more commonly known as the H-bug) and others were more common ones, such as those that cause Athlete's Foot.
Manuka Oil is rapidly gaining popularity in the field of Aromatherapy. Some aromatherapists believe that although the effectiveness of Manuka Oil as a bactericide and fungicide is dramatic - Manuka Oil has another side. A leading German Aromatherapist, Ruth von Braunschweig, reports on the sensual, "feel good" side of Manuka Oil, stating it to be beneficial for people with over sensitive nervous systems and those who suffer from stress and anxiety, conditions that often manifest themselves in allergic reactions.
