Litsea cubeba, the aromatic litsea or may chang, is an evergreen tree or shrub 5–12 meters high in the family Lauraceae. It is native to Southern Chinese region including Sichuan, Guizhou, Yunnan, Taiwan and Fujian, and Southeast Asian countries such as Indonesia, Malaysia and Cambodia. It is called “mountain pepper” (山胡椒; pinyin: shānhújiāo), “mujiangzi” (木姜子; pinyin: mùjiāngzǐ)or “douchijiang” (豆豉姜; pinyin: dòuchǐjiāng) in Mandarin and maqaw (馬告) by the Atayal aborigines in Taiwan. 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.
