Oil Mallee

Eucalyptus kochii

For generations, people across the eucalypt country of Western Australia have turned to the sharp, camphor-sweet leaves of mallee eucalypts like Eucalyptus kochii for relief from coughs, colds, and heavy chests. Aboriginal Australians crushed and steamed the aromatic foliage of local eucalypts to help clear the airways and ease fever, a practice that settlers later adapted into the now-familiar ritual of eucalyptus steam inhalation. Eucalyptus kochii itself became the backbone of Western Australia's modern oil mallee industry, its narrow leaves yielding an exceptionally pure, high-cineole oil that growers and herbalists still prize today. Long before it was bottled and sold, that same bracing scent simply meant one thing to households nearby, that a cold was about to meet its match.

Safety.

The concentrated essential oil of oil mallee is genuinely dangerous if swallowed, even a teaspoon can seriously poison a small child, so keep it out of reach and use only externally or as vapor. Do not hold steam preparations close to the face of infants or young children.
