Amomum villosum

Amomum villosum () is a plant in the ginger family that is grown throughout Southeast Asia and in South China.[2] Similar to cardamom, the plant is cultivated for their fruits, which dry into pods when mature and contain strongly aromatic seeds.[3] The pods are used in Chinese cuisines to flavour soups and in Chinese herbology to treat stomach ache and dysentery.[3]

Due to the demand for the seeds and the ripe fruits of the plant and to curb slash-and-burn activities in their forests by local populations, cultivation of the A. villosum and co-plantings with rubber trees has been encouraged by the governments of Yunnan and Guangdong, China.[4] However, the extensive cultivation of A. villosum in the forest has resulted in the reduction of species diversity in the rainforest of Southwest China.[5]
