A rare non-native Eucalypt gum-tree likely to be found only in parks and large gardens. Like most, if not al Eucalypts, the leaves give off a smell of eucalyptus, which contains many highly volatile and flammable vapours. Whole forests of Gum Trees in Australia give off so much vapour on hot days that a blue haze fills the air above the forest. The fumes are dangerously inflammable and have been the cause of forest fires following some source of ignition.

The essential oil of Eucalyptus is used as a flavouring in pharmaceutical products and some medicinal toffees such as cough candy, lozenges, and is also used in ointments and inhalants to help with congested airways and breathing. It is safe at the low doses used, but is toxic at higher doses. Children in particular may suffer from severe poisoning at doses as low as 5mL of eucalyptus oil. It has a powerful woody smell and is used as a fragrance for cosmetics, soap bars and such like. Eucalyptus oil contains variable proportions of Phellandrene, Piperitone, Citral, Methyl Cinnamate, Geranyl Acetate, Limonene and Cineole, depending upon the type of Eucalyptus Tree it is derived from; there are over 300 different ones. Eucalyptus oils containing Cineole are especially differentiated between those not containing it.

It is not surprising that Eucalyptus oil, containing so many ingredients, is anti-microbial, anti-bacterial and analgesic. Eucalyptus Oil containing Cineole is also an insect repellant and pesticide and has also been found to prevent the separation of ethanol and petrol in petrol pump fuel 'fortified' with ethanol. Eucalyptus Oil itself has a fairly high octane rating, but is too expensive to be used as a fuel.
