Cinnamomum camphora (commonly known as camphor tree, camphorwood or camphor laurel) is a large evergreen tree that grows up to 20–30 m (66–98 ft) tall. The leaves have a glossy, waxy appearance and smell of camphor when crushed. In spring, it produces bright green foliage with masses of small white flowers. It produces clusters of black, berry-like fruit around 1 cm (0.39 in) in diameter. Its pale bark is very rough and fissured vertically.
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.
In Japan, where the tree is called kusunoki, five camphor trees are known with a trunk circumference above 20 m, with the largest individual, Kamō no Ōkusu (蒲生の大楠?, "Great camphor of Kamō"), reaching 24.22 m.
Camphor laurel contains volatile chemical compounds in all plant parts, and the wood and leaves are steam distilled for the essential oils. Camphor laurel has six different chemical variants called chemotypes, which are camphor, linalool, 1,8-cineole, nerolidol, safrole, or borneol. In China, field workers avoid mixing chemotypes when harvesting by their odour. The cineole fraction of camphor laurel is used in China to manufacture fake "Eucalyptus oil".
