Yomogi (Artemisia princeps) is the Japanese mugwort. Its most famous culinary appearance is in kusa-mochi — the green mochi colored and flavored with pounded yomogi leaves — but the plant has a long presence in traditional medicine, moxibustion (the moxa of kyū therapy is compressed yomogi), and bathing culture. In cosmetics, the leaf extract appears in formulations for sensitive and reactive skin.

What it is
Artemisia princeps leaf extract is produced by water, hydro-alcoholic, or glycol extraction of the leaves of Artemisia princeps. The extract contains chlorogenic acid, flavonoids including eupatilin and jaceosidin, organic acids, and trace essential oil constituents such as 1,8-cineole and camphor.
Yomogi is sometimes confused with Artemisia vulgaris (common mugwort) or Artemisia annua (sweet wormwood). Artemisia princeps is specifically the East Asian species used in Japan and Korea.
Typical uses in Japanese products
In Japanese cosmetics, yomogi leaf extract is frequently used in sensitive-skin lines, scalp-care products, bath additives, and face masks. Many Japanese sensitive-skin formulations combine yomogi with other traditionally soothing ingredients such as Glycyrrhiza uralensis root extract and allantoin.
Culturally, yomogi carries a spring association — the first tender leaves of spring yomogi are the traditional raw material for the year's kusa-mochi and kusa-dango.
