Artemisia argyi is a perennial herb or semi-shrub of Compositae and Artemisia, and it is a natural mosquito repellent material.

Main value

Wormwood is also good food. In the traditional food in southern China, there is a kind of Ciba made of wormwood as the main raw material. That is, the fresh and tender wormwood and glutinous rice flour before and after the Qingming Festival are mixed together in a ratio of one to two, wrapped with peanuts, sesame seeds, sugar and other fillings (mung bean paste will be added in some areas), and then steamed.

In the Dongjiang Valley of Guangdong Province, local people pick fresh leaves and buds of wormwood as vegetables in winter and spring. Every year in early spring, Hakka people in Ganzhou have the custom of collecting wormwood to make mugwort. Amigo is a bit like jiaozi in shape, but it is bigger and has stuffing inside. It's delicious and can be used as a staple food.
