Botanical Source of Eucalyptus Essential Oil
Eucalyptus essential oil is distilled from the leaves of eucalyptus trees, most commonly:

Eucalyptus globulus
-
Eucalyptus radiata
Native to Australia, eucalyptus trees are now cultivated worldwide. Different species vary slightly in aroma and strength, with E. radiata often considered gentler for topical use.
How Eucalyptus Essential Oil Is Made
Eucalyptus essential oil is extracted through steam distillation of fresh eucalyptus leaves. The distillation process captures the oil’s high cineole content, which gives eucalyptus its strong, cooling, and penetrating aroma.
High-quality eucalyptus oil should smell clean, sharp, and medicinal — not sweet or musty.
