Eucalyptus Essential Oil is a concentrated liquid containing volatile aromacompounds from the Eucalyptus Globulus Tree. It is usually distilled, sometimes expressed or solvent extracted. Eucalyptus essential oil is said to be antibacterial, disinfectant and an analgesic. It has been used to relieve coughs, colds, and other such respiratory troubles. It soothes muscle and joint pains, and helps to heal wounds, burns, ulcers and insect bites. In aromatherapy eucalyptus is said to promote activity, vitality, and energy. Essential oils have been understood to have played a role in healing in ancient times in Egypt, China, and other parts of the world. They are said to be the oldest form of medicine and cosmetic, since they are distilled from plants, not involving complicated processes or machinery, but an art nonetheless. For their healing and aromatic properties, they were considered more valuable than gold to the ancients.
