A little more information:
Mugwort’s generic name is from that of the Greek moon goddess Artemis, a patron of women. Mugwort has long been considered an herbal ally for women particularly for the regulating of the menstrual cycle and easing the transition into menopause. The common name is thought to be from the old English word moughte meaning “moth,” or mucgwyrt, meaning “midgewort,” referring to the plant’s folk use to repel moths and other insects.
Mugwort has a long history of folk tradition and use. Anglo-Saxon tribes believed that the aromatic mugwort was one of the nine sacred herbs given to the world by the god Woden. It was used as a flavoring additive to beer before hops (Humulus lupulus) became widely used. Mugwort is considered a magical herb, with special properties to protect road-weary travellers against exhaustion. The Romans planted mugwort by roadsides where it would be available to passersby to put in their shoes to relieve aching feet. It is said that St. John the Baptist wore a girdle of mugwort when he went out into wilderness for his mystic practices. Some of the magic in mugwort is in its reputed ability to induce prophetic and vivid dreams when the herb is placed near the bed or under the sleeper’s pillow. In Pagan ceremonies a garland or belt of mugwort is worn whilst dancing around the fire during celebrations of the summer solstice. The herb is then dashed into the fire to ensure continued protection throughout the coming year.
