Litsea cubeba

It is native to Southern Chinese regions including Sichuan, Guizhou, Yunnan, and Fujian as well as Taiwan and other Southeast Asian countries such as Indonesia, Malaysia and Cambodia.

It produces a fruit which is processed for its lemony essential oil.

The oil can also be extracted from the leaf, but this is considered to be lower in quality.

[1] It is mainly produced in China from plantations and is marketed as "Litsea cubeba", with production estimates between 500 and 1,500 tonnes of oil per annum.

It is also used as a raw material by the chemical industry for the synthesis of vitamin A and violet-like fragrances.
