Amomum tsaoko

Lanxangia tsaoko, formerly Amomum tsao-ko, is a ginger-like plant known in English by the transliterated Chinese name cao guo (Chinese: 草果; pinyin: cǎoguǒ). It grows at high altitudes in Yunnan, as well as the northern highlands of Vietnam. Both wild and cultivated plants are used medicinally and also in cooking.
