However, the Taiwanese endemic, Cinnamomum kanehirae (listed as 'Endangered' in 1998 and now viewed as a form of Cinnamomum micranthum), was an abundant tree species at the beginning of the twentieth century and is one of the most valuable timber species in Taiwan. More recently it has become rare through years of clearing forestland and illegal selective cutting.

Cultivation Details

Cinnamomum micranthum is native from warm temperate to tropical regions of southern China and northern Vietnam. It is somewhat frost tolerant and is likely to succeed outdoors in milder areas of the temperate zone so long as summers are warm enough to fully ripe the current season's growth.
Species in this genus generally prefer an acidic soil with ample moisture in the growing season and a position with some shade[

This species is the major host for the medicinal fungus Antrodia cinnamomea, which exhibits potential anticancer and hepato-protective properties. The fungus is much used in traditional medicine to treat a range of conditions, and the tree is used both to harvest the fungus and also to cultivate it. A growing quantity of evidence shows that extracts, fermented products, or compounds isolated from the fungus possess growth inhibitory activity against various types of cancers[
