Overview
Mugwort is a widespread aromatic herb with a rich history of use across Europe, Asia, and North America. It has been used for centuries for digestive support, menstrual regulation, vivid dreaming, and in Traditional Chinese Medicine as the primary herb for moxibustion. The plant contains thujone and other compounds that require caution, particularly during pregnancy. While generally safe in culinary and moderate medicinal amounts, high doses or prolonged use should be avoided.
Traditional Use
Mugwort has one of the most diverse and widespread histories of any medicinal plant. In Europe, it was considered a magical protective herb, hung over doorways to ward off evil spirits and used by travelers to prevent fatigue. Anglo-Saxon herbalists listed it as one of the nine sacred herbs. In Traditional Chinese Medicine, dried mugwort (moxa) is burned near acupuncture points in moxibustion therapy, one of the most important TCM treatments. Japanese and Korean traditional medicine use it similarly. Native American tribes used related Artemisia species for digestive complaints, menstrual regulation, and as a smudging herb. In culinary traditions, mugwort is used to flavor beer (before hops), rice cakes in Japan (yomogi mochi), and various dishes across Asia. The plant's association with dreams and altered states has made it popular in modern herbalism for promoting vivid, lucid dreaming.
