Artemisia argyi refers to wormwood growing in Qichun County, Hubei Province, which is named after its variety and origin. Compared with common mugwort, mugwort has natural advantages.
First of all, Artemisia argyi leaves are round, wide and thick, with nine lobular tips; The plant of Artemisia argyi is tall and can reach more than 2 meters; The common Artemisia argyi plant is about 1 m high, with thin leaves and sparse hair. This is the uniqueness of mugwort in appearance and shape.

From the beginning, it was called mourning, and Qichun won, and Manchu made the world heavy. " (Translation: In modern times, only Tangyang's so-called North Ai and Siming's so-called Hai Ai, since Chenghua, Qichun has been the winner, a specialty and the most important salary for Ai. ")
