Like most species of Eucalyptus, Eucalyptus Radiata is native to Australia. A very large flowering evergreen tree in the myrtle family, Eucalyptus Radiata produces fragrant leaves. Because of it's foliage it is also known, informally, as narrow-leaved peppermint. Eucalyptus trees can survive more than 250 years and the Radiata species can be over 160' tall at maturity.
It's also been known as fever tree because of what happened when the French government planted eucalyptus trees in Algeria in 1857. In just five years the trees turned a once marshy land where they were planted, into a drier region, which ultimately reduced the mosquito habitat. The assumption is that by reducing the number of mosquitos it reduced the number of Malaria cases thus reducing fever.
The Essential Oil
Eucalyptus Radiata essential oil is found in these blends R.C.™, Raven™, and Thieves®, all of which are excellent respiratory support.
While each variety produces some of the same benefits, similar to those of Tea Tree and Myrtle EO, they have unique aromas. Eucalyptus Radiata is a clean, refreshing, slightly citrusy scent making it a good rejuvenator when you need to be clear headed and have a little pep in your step.
In 2011 a study at Heidelberg University found that Eucalyptus Radiata has the second highest levels of cineol (eucalyptol) after Eucalyptus globulus. It's also high in citronella and monoterpenes. Regarding monoterpenes, an article on Science Direct says, "They are known for their many biological activities such as antimicrobial, hypotensive, anti inflammatory, antipruritic, antigerminative, antiplasmodial, anti esophageal cancer, and anticandidal." And goes on to say, "More recently, they have played a great role in the pharmaceutical industry because of their potential."1
Not only because of the constituents that make up Eucalyptus, it is being studied because it's been used historically with good results for hundreds, if not thousands of years for all types of healing. Antibacterial, antifungal, antiviral and antimicrobial activities are discussed in articles on National Institute of Health (NIH).2 And one study suggests that it be used to inhibit what's currently affecting the whole world.3
HISTORICAL USES OF EUCALYPTUS
- Topical ointments containing eucalyptus have been used in traditional Aboriginal medicine to support wound healing.
- Australian Botanist Ferdinand von Mueller found Eucalyptus made a good disinfectant in 1852.
- During the 19th century in England, eucalyptus was used in hospitals to clean urinary catheters.
- Italians used the plant to help combat malaria.
- In 1885 it made its way into the British Pharmacopoeia.
