General Information on Eucalyptus Oil
Types and production
Eucalyptus oils in the trade are categorized into three broad types according to
their composition and main end-use: medicinal, perfumery and industrial.
The most prevalent is the standard cineole-based "oil of eucalyptus", a
colourless mobile liquid (yellow with age) with a penetrating, camphoraceous,
China produces about 75% of the world trade, but most of this is derived from
camphor oil fractions rather than being true eucalyptus oil.
Significant producers of true eucalyptus oil include South Africa, Portugal,
Spain, Brazil, Australia, Chile and Swaziland.
Global production is dominated by Eucalyptus globulus.
However, Eucalyptus kochii and Eucalyptus polybractea have the highest cineole
content, ranging from 80-95%.
The British Pharmacopoeia states that the oil must have a minimum cineole content
of 70% if it is pharmaceutical grade.
Rectification is used to bring lower grade oils up to the high cineole standard
Global annual production of eucalyptus oil is estimated at 3,000 tonnes.
The eucalyptus genus also produces non-cineole oils, including piperitone,
phellandrene, citral, methyl cinnamate and geranyl acetate.
Australian Aboriginals use eucalyptus leaf infusions
as a traditional medicine for treating body pains, sinus congestion,
fever, and colds.
Dennis Considen and John White, surgeons on the First Fleet, distilled eucalyptus
oil from Eucalyptus piperita found growing on the shores of Port Jackson in 1788
to treat convicts and marines.
Baron Ferdinand von Mueller, Victorian botanist, promoted the qualities of
Eucalyptus as a disinfectant in "fever districts".
Surgeons were using eucalyptus oil as an antiseptic during surgery by the 1880s.
