The best-known and most precious oil in aromatherapy, thanks to its unparalleled versatility and strength. The history tells that Captain James Cook arrived in Australia and was greeted with tea made from the Melaleuca leaves, hence the name. Cook observed that the natives used its leaves to make plasters that were applied to wounds to treat infections. In 1922, its distillation and analysis of its properties was carried out and, in World War II, the oil was already part of the first aid kit of the Australian navy.
