The mugwort plant has been traditionally used for everything from digestive disorders to beer-making, insect repellent, and more. Historically, mugwort was used by the Romans, who are said to have planted it by roadsides, so that marching soldiers could put the plant in their shoes. This was done to relieve aching feet. St. John the Baptist was said to have worn a girdle of mugwort. In addition to its medicinal use, mugwort has been used for smudging, protection, and inducing vivid dreams (when placed underneath a person’s pillow).
