Mugwort (Artemisia vulgaris L.) is a plant related to ragweed used as a food flavorant and for herbal medicine. It is thought to boost energy, calm nerves, support digestion, relieve itching and pain, and promote regular periods, among other things. The evidence supporting these claims is lacking.
Mugwort is available as a dietary supplement, tincture, extract, essential oil, powder, or whole dried leaves. It is generally safe for use, although it may cause an allergic reaction in people with ragweed allergies as well as allergies to celery, carrot, or birch. There is no recommended dose.
Mugwort should not be used in children or people who are pregnant or breastfeeding.
