Eucalyptus Oil Origins
Eucalyptus oil is distilled from leaves of select species of eucalyptus trees (most commonly Eucalyptus globulus), which are native to Australia. The fragrance of the trees — and the oil — is described variously as bright, woody, coniferous, camphoraceous, crisp and refreshing. Some say a whiff of eucalyptus oil has a medicinal scent. The oil’s biological properties are wide-ranging, according to the National Institutes of Health, from antimicrobial and antiseptic to insecticidal. It is lethal to mites, repels insects and even removes grease, the NIH says.
