Artemisia scoparia Waldst. & Kit.

Artemisia scoparia Waldst. & Kit.. Artemisia scoparia, commonly known as virgate wormwood, capillary wormwood, or redstem wormwood, is a perennial aromatic herb in the genus Artemisia, in the sunflower family. It is widespread across much of Eurasia from France to Japan, including China, India, Russia, Germany, Poland, and central and southwest Asia. In Mandarin Chinese it is known as yīn chén or zhū máo hāo (猪毛蒿). The dried herb — Artemisiae Scopariae Herba (ASH) — is an officially recognised drug in the Chinese Pharmacopoeia and is considered interchangeable with the closely related Artemisia capillaris Thunb. for medicinal purposes. Its pollen can be allergenic in sensitised individuals.
