Product Abstract
Eucalyptus actually refers to a large genus of flowering trees that has over 700 different species, most of which are located in Australia and New Zealand, although some of the more widespread species can be found throughout Southeast Asia. Most of its species range from the size of a small shrub to a medium-sized flowering tree, but all species have leaves that are covered in oil glands, from which the majority of the health benefits are derived.
History
California. In the 1850s, Eucalyptus trees were introduced to California by Australians during the California Gold Rush. Much of California has a similar climate to parts of Australia. By the early 1900s, thousands of acres of eucalypts were planted with the encouragement of the state government. It was hoped that they would provide a renewable source of timber for construction, furniture making and railroad ties. It was soon found that for the latter purpose eucalyptus was particularly unsuitable, as the ties made from eucalyptus had a tendency to twist while drying, and the dried ties were so tough that it was nearly impossible to hammer rail spikes into them.
Harvesting/Extraction Information
The oil is extracted by a distillation process that separates it from the dried eucalyptus leaves. That extracted oil is used in countless health-related ways and products. In terms of application today, eucalyptus oil is used in insect repellent, as a disinfectant, for Asthma, treatment, and other uses too numerous to mention here.

Safety summary
Hazards May be choleretic.
Contraindications (oral) Cholestasis.
Reproductive toxicity The low reproductive toxicity of 1,8- cineole, (þ)-limonene, linalool and a-pinene suggests that eucalyptus macarthurii oil is not hazardous in pregnancy.
Gastrointestinal toxicology Since geranyl acetate is choleretic, Eucalyptus macarthurii oil should not be taken in oral doses by people with cholestasis.
Systemic effects
Acute toxicity No information found.!
Carcinogenic/anticarcinogenic potential No information ! found for eucalyptus macarthurii oil, but it contains no known carcinogens. Geranyl acetate is not a rodent carcinogen; (þ)- limonene and geraniol are anticarcinogenic.
Comments
There are three chemotypes, with varying amounts of geranyl acetate, 1,8-cineole, geraniol, (þ)-limonene and eudesmol. Geranyl acetate can be as high as 70%. This oil is usually rectified to remove unwanted aldehydes.
