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, and Japan.
In spring, it produces bright green foliage with masses of very small white fragrant flowers from which its common namesake "smells good tree" in Chinese 香樟 xiang zhang was given.
The species is native to China south of the Yangtze River, Taiwan, southern Japan, Korea, India, and Vietnam, and has been introduced to many other countries.
[4] In Australia, the larval stages of two native butterflies, the purple brown-eye and common red-eye feed on camphor despite it being an introduced plant.
The camphor content of the leaf litter helps prevent other plants from germinating successfully, helping to ensure the camphor's success against any potentially competing vegetation,[7] and the seeds are attractive to birds and pass intact through the digestive system, ensuring rapid distribution.
Camphor laurel invades rainforests and pastures, and also competes against eucalyptus trees, certain species of which are the sole food source of koalas.
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).
The species contains volatile chemical compounds in all plant parts, and the wood and leaves are steam distilled for the essential oils.
