Cinnamomum camphora is native to China south of the Yangtze River, Taiwan, southern Japan, Korea, and Vietnam, and has been introduced to many other countries.
Camphor laurel contains volatile chemical compounds in all plant parts, and the wood and leaves are steam distilled for the essential oils.
British Columbia's northern forests produce some of the finest trees and fibre available for paper.
The ideal climate encourages slow growth of white spruce, lodgepole pine and alpine fir.
In India and Sri Lanka, the high camphor variety/chemotype remains dominant. camphora grown in Madagascar, though, is high in 1,8 cineole (averaging between 40 and 50%).
Camphor laurel has six different chemical variants called chemotypes, which are camphor, linalool, 1,8-cineole, nerolidol, safrole, and borneol.
In China, field workers avoid mixing chemotypes when harvesting by their odour.
It has become a noxious weed throughout Queensland and central to northern New South Wales, where it is suited to the wet, subtropical climate.
However, the tree provides hollows quickly in younger trees, whereas natives can take hundreds of years to develop hollows.
