The Cold and 'Flu Remedy
Eucalyptus essential oil is extracted from the leaves and twigs of the Eucalyptus tree (Eucalyptus globulus), using steam distillation. The word "Eucalyptus" is derived from the Greek "eu" and "kalypto" meaning "well" and covered" (referring to the cup-like membrane that covers the flower bud that is thrown off as the flower expands). The Australian Blue-Gum tree is one of the major sources of Eucalyptus essential oil.
There are over 500 different species of Eucalyptus trees and they have blue-green, narrow, long and tough leaves. The flowers are creamy-white, and the bark is very papery and peels off on the sides of the trunk. If you have ever seen a Koala bear, then you have probably seen an Australian Blue-Gum tree, as this tree is the natural habitat of this cute-looking, highly strung bear.
The Surgeon General of the Australian colony, Dr John White, first distilled Eucalyptus essential oil in Australia in 1788.
Interest in the Australian Blue-Gum tree developed because it is very fast growing and uses up immense amounts of water. Eucalyptus trees are therefore used in agriculture to turn marshy, swampy ground into usable, arable land. This process also helps to eradicate the breeding ground of the malaria mosquito, helping the tree gain a reputation in the 19th century of being able to rid an area of fever or "miasma" (the source of malaria was not yet known), hence the name "Fever tree". Aborigines chew the roots of the Australian or Tasmanian Blue-Gum for their water content and also bind wounds with Eucalyptus leaves to promote healing.
Various ways to use Eucalyptus oil:
- Burners or Vaporizers: - Depending on the size of the reservoir, 6 to 8 drops of this oil can be added, to assist with frequent sneezing, hay fever, 'flu, respiratory problems and as an insect repellent.
- Blended massage or in the bath: - 6 drops may be added to a bath, or 40 drops to 100ml of carrier oil (2000 drops = 100ml) for a blended massage. This will help relieve: arthritis, asthma, bronchitis, mucus congestion, colds, headaches, rheumatism, sinusitis, catarrh, fatigue and muscular aches and pains.
- Used neat or dab on with a bud: - May be used neat on the skin for insect bites or wounds, but care should be taken when doing so.
- Eucalyptus oil can be dropped onto a pieces of cloth or cotton wool and placed in the corners of your cupboards to repel cockroaches and to fragrance your clothes. Please take care that the oil does not come into contact with your clothes as it may stain.
