A brief history...
When Captain Cook visited Australia in the 18th century, he became familiar with the “healing tree”. The leaves form the Melaleuca alternifolia had been falling into the water for over 100 years and this had turned the lakes into antiseptic baths. After allowing his crew to swim in the lake, wounds, cuts, scalds and other skin irritations were healed. The colour of the water reminded Captain Cook of tea hence, according to folklore, the name Tea Tree. The local Aboriginal tribe, Bundjalungy, used Tea Tree to treat many skin problems by adding crushed Tea Tree leaves into hot compresses and poultices.
During the second World War the Australian Army obtained possession of all Tea Tree Oil to treat injured soldiers, and production of oil was considered an essential war time industry. Therefore, leaf-cutters in the plantations were exempt from military service, and, it was added to the first aid kit of nearly every Aussie soldier and sailor assigned to subtropical regions during WWII. The oil was especially important when battling in the jungle where mosquitoes and other blood sucking insects were a hazard. Wounds, cuts and insect bites were treated with oil, the antiseptic properties eased discomfort while healing was enhanced and the risk of infection significantly diminished.
