Historical record

Revered in the Anglo-Saxon 9th-century 'Nine Herbs Charm' as 'Una', the oldest and fiercest of herbs. Ancient Roman soldiers placed sprigs in their sandals to alleviate foot fatigue during long marches.

Folklore and mythology

Hung over doors on Midsummer's Eve to ward off malicious spirits and lightning. Sleeping on a mugwort pillow induces vivid, prophetic dreams. Travelers carried it as an amulet against beasts and sunstroke.

Dedicated to Artemis (Diana), the Greek virgin goddess of the hunt, wild nature, and childbirth, who was believed to grant the plant its strength to assist women in labor.

Midsummer wreaths were another recorded use.

Tradition: Greco-Roman & Anglo-Saxon Associated figures: Artemis (Diana) & Odin
