Traditional uses

Brooker's Gum is one of Tasmania's tall wet-forest eucalypts, named for the Australian botanist M.I.H. Brooker, who spent his career mapping and describing the eucalypt family. It has not carried the long, well-documented medicinal history of its famous cousin, Eucalyptus globulus, the Tasmanian Blue Gum whose leaf became a mainstay of colonial and folk respiratory remedies. Instead, Brooker's Gum has traditionally been valued in its home range as a fast-growing timber and shelter tree and as a source of nectar for the region's celebrated eucalypt honeys. Because it shares the same aromatic, oil-rich leaves common to the genus, bruised foliage has sometimes been gathered in the bush the way other eucalypts were, crushed and breathed in for their sharp, clearing scent on a cold or congested day.

Did you know?

Brooker's Gum is unusual among eucalypts for tolerating the boggy, poorly drained valley flats of the Tasmanian highlands, ground that would leave most of its drainage-loving relatives struggling.

Safety

Eucalyptus leaf and oil are toxic if swallowed and can seriously harm children and pets even in small amounts, so they are never taken internally; undiluted oil should also be kept off the skin, especially on infants.
