What is eucalyptus essential oil?

The eucalyptus tree (aka gum tree) is an indigenous Australian plant that belongs to a genus of over 700 species of flowering trees or shrubs. It’s part of the myrtle family, Myrtaceae, and is one of the tallest plants on the planet. However, it can also grow as a shrub. Australia’s indigenous people, the Aborigines, consider the tree to be a holy one, and they believe that it represents the division of heaven, the earth and the underworld.
The Aborigines first used eucalyptus to treat fevers, so it’s sometimes referred to as the Australian Fever-Tree, but we’ve found many other ways to use it since then.
As in the case of most essential oils, eucalyptus oil contains many active natural compounds, but the most important is 1,8 cineole. This gives the oil its unique scent and imparts many medicinal properties.
Eucalyptus essential oil - quick facts
🍃 Latin name: Eucalyptus globulus
🍃 Also known as: Blue gum tree
🍃 Country of origin: 🇦🇺 Australia
🍃 Scent note: Camphoraceous
🍃 Annual production: Upwards of 17,000 tonnes
🍃 Popular uses: cold and flu symptoms, pain, relaxation, disinfection
How is eucalyptus essential oil made?

Although Eucalyptus globulus is native to Australia, China has become the world-leading producer, with India producing a fair amount as well.
Generally, extraction methods for creating eucalyptus oil include hydro-distillation, microwave-assisted hydro-distillation, solvent-based distillation, steam distillation, and ultrasound-assisted extraction.
Distillation is defined as a process that involves the conversion of liquids into vapor and then condensing this back into liquid. A great example of distillation is when steam from a kettle gets deposited as drops of water on a cold surface.
