About
Camphora officinarum is a species of evergreen tree indigenous to warm temperate to subtropical regions of East Asia, including countries such as China, Taiwan, Vietnam, Korea, Japan and India. It is known by various names, most notably the camphor tree, camphorwood or camphor laurel.
Where it grows
The species is native to Japan, Korea, the Ryukyu Islands, and Taiwan. It has been introduced to China south of the Yangtze River, the Himalayas, Bangladesh, Cambodia, Laos, Vietnam, eastern Australia, the southeastern United States, and many other countries.
Uses
The species is cultivated for camphor and timber production. The production and shipment of camphor, in a solid, waxy form, was a major industry in Taiwan prior to and during the Japanese colonial era (1895–1945). It was used medicinally and was also an important ingredient in the production of smokeless gunpowder and celluloid. Primitive stills were set up in the mountainous areas in which the tree is usually found. The wood was chipped; these chips were steamed in a retort, allowing the camphor to crystallize on the inside of a crystallization box after the vapour had passed through a cooling chamber. It was then scraped off and packed out to government-run factories for processing and sale. Camphor was one of the most lucrative of several important government monopolies under the Japanese.
