Deodorant; Essential; Preservative; Repellent; Wood. The essential oil ‘camphor’ is obtained from the leaves and twigs. It is extracted commercially by passing a current of steam through the wood chips, 30 kilos of wood yielding 1 kilo of camphor. Camphor is used medicinally, in perfumes, as an insecticide and also to make celluloid and as a wood preservative. It can also be put in shoes to cure perspiring feet (probably by acting as a deodorant rather than preventing perspiration). The wood has been burnt as a fumigant during epidemics. Wood – beautifully grained, light brownish, takes a good polish. It is used for making furniture, cabinets, the interior finish of buildings etc.

Notes: Common park and shade tree. Now extensively naturalised and in some localities a major problem of grazing land, disturbed rainforest and urban bushland. Especially invasive of stream banks, reducing light and crowding out other species. In some areas forms a monoculture for the entire length of a watercourse. The plant produces oil which possibly causes death of fish and invertebrates.
