Numerous tiny, tubular, brownish flower heads are borne in dense racemose panicles. The plant has a characteristic strong, spicy-aromatic fragrance due to volatile oils including cineole and camphor.

Cultural & Historical Context

Traditional Chinese Uses

Ai Ye (mugwort leaf, artemisia leaf) is a warm, bitter-pungent herb with a strong warming action on the lower burner and Chong and Ren vessels. It is used for cold-type menstrual disorders including painful menstruation, excessive menstrual bleeding from deficiency cold, and threatened miscarriage from uterine cold. Externally, it is the primary substance used in moxibustion therapy — burned over acupuncture points to warm channels and dispel cold. It also treats itching skin conditions when used as a wash.
