What is Eucalyptus?

Eucalyptus globulus is a tall fast-growing tree native to Tasmania and southeastern Australia. The leaves contain substantial 1,8-cineole (eucalyptol) - the compound responsible for the unmistakable "eucalyptus" aroma and the herb's well-documented respiratory effects. Eucalyptus has been used in Australian Aboriginal traditional medicine and was adopted globally during the 19th-century era of European exploration. Eucalyptus oil is one of the most commonly used essential oils worldwide.

How to Use Eucalyptus Leaf

Steam inhalation (the most popular use): place 1-2 tablespoons of leaves in a heatproof bowl; pour just-boiled water over them; drape a towel over your head and breathe the steam (with eyes closed) for 5-10 minutes. Tea: steep 1 teaspoon in 8 oz hot water for 5-10 minutes (the flavor is intensely aromatic and can be strong). Shower aromatics: hang a bundle of eucalyptus in the shower for aromatic steam.

Safety Information

Eucalyptus is generally safe in standard tea and steam-inhalation preparations. Eucalyptus essential oil (much more concentrated than the leaf) requires more caution - not recommended near infants and young children, and should not be applied undiluted to skin. Not recommended for individuals with seizure disorders (high doses of eucalyptol have been associated with seizures in sensitive individuals).
