This divine essential oil is derived from a tree native to Australia, but is also grown in South Africa. Eucalyptus smithii or gully gum tree grows placidly on low slopes and in watery wetlands where soil stays moist. This is the most mellow and soft of all Eucalyptus species and the essential oil has all of the same healthy attributes of its plant cousins. The aroma is gently camphorous, wonderfully alive, fresh and faintly earthy. This mild species is gentle when used properly on sensitive adults and is the Eucalyptus of choice for delicate skin when mixed into carrier oils. A few drops enliven massage oils, freshen-up stale ambient air and impart a feeling of comfortable, grounded entrenchment. Diffusion, inhalation and dermal application are just a few options for using this unique essential oil. Eucalyptus smithii essential oil is distilled from the leaves.
