The part of the eucalyptus tree used in healing is the oil distilled from its leaves. There are over 300 species of eucalyptus trees, most indigenous to Australia and Tasmania. A small number of the species are actually used in industry and medicine.
Aromatic
Certain species of eucalyptus provide odor or scent. The species E. citriodora contains a lemon scent used in making perfumes. E. dives and E. radiata release oils with a peppermint flavor.
Astringent
Eucalyptus oil has astringent properties that are useful for inflammation and wounds. The tree, as well as the oil it produces, absorbs moisture and is planted in malarial areas to absorb the water and remove the breeding ground for mosquitoes carrying malaria.
Decongestant
Over-the-counter cough and cold medicines incorporate eucalyptus because of its effect as an expectorant and decongestant. Ointments containing eucalyptus and other essential oils are also used for the same purposes.
Antimicrobial
Listerine mouthwash uses eucalyptus in combination with menthol, methyl salicylate and thymol to reduce dental plaque and gingivitis. Veterinarians use eucalyptus oil topically for parasitic skin infection.
Rubefacient
Eucalyptus is a rubefacient and will increase blood circulation when applied to the skin. This property can also cause blistering if too much is applied. Rheumatic pain can be relieved with eucalyptus.
Industrial
Eucalyptus oils used in industrial settings contain terpenes. The terpenes in eucalyptus are used in flotation processes (separation of minerals from useless debris by taking advantage of the hydrophobicity of the substances) found in mining operations.
