What is Eucalyptus Smithii?
Eucalyptus smithii is a milder, gentler species of eucalyptus native to Australia and ideal for therapeutic use—especially for children and sensitive individuals. It contains lower levels of cineole than Eucalyptus globulus, making it less irritating to the respiratory tract and skin. It is steam-distilled from the leaves and twigs of the Eucalyptus smithii tree and is known for its clear, penetrating, camphoraceous aroma.
