"During WWII and the 1940’s, it became more apparent that tea tree oil was a valuable resource to not only the Australian economy, but to the overall health of soldiers and factory workers as well."
Just before the outbreak of WWII, a study published by the Medical Journal of Australia found that tea tree oil was effective in treating infections of the skin and nails, and in dissolving the pus of those infected areas. It also reported that sore throats went away more quickly when gargling with a few drops of tea tree oil added to a glass of water.
It was an age of discovery, and before the advent of penicillin in the late 1940’s, it was found to be useful against dental problems, throat and mouth infections, fungal infections, Candida, and other skin infections.
As a disinfectant, it was added to the first aid kit of nearly every Aussie soldier and sailor assigned to subtropical regions during WWII .
It found it’s place in machine shops and ammunition factories, because it was observed that diluting the cutting oil used in metal shops with just 1% tea tree oil reduced the rate of infection dramatically from the metal shaving and splinters that are common in such work.
Field hospitals used bandages that were treated with tea tree oil in order to reduce infection in wounds, and even today, tea tree oil is used in some burn ointments and emergency gel packs to reduce the pain and minimize infections from serious burns.
