Mugwort (Artemisia vulgaris), a member of the Artemisia plant family, has a long record in herbal medicine for digestion, menstrual regulation, and skin conditions, and recent summaries of the available research point to specific antioxidant, digestive, and traditional uses worth understanding.
What is mugwort and where does it come from?
Mugwort is an aromatic herb in the Artemisia family, the same botanical group as wormwood and tarragon. It has been described as a traditional bitter herb in both Eastern and Western medicine. During medieval times it was used as a beer flavoring, and it is listed as one of the nine sacred herbs associated with the summer solstice. The plant is also the source of “moxa,” the dried herb burned close to the skin in moxibustion, a practice tied to acupuncture.
What antioxidant effects has research measured?
Research shows mugwort contains antioxidant compounds.
A study published in the Journal of the Science of Food and Agriculture measured total phenols, flavonoids, proanthocyanidins, and vitamin C levels in Mauritian vegetables, and assessed antioxidant activity using Trolox Equivalent Antioxidant Capacity (TEAC) and Ferric Reducing Antioxidant Power (FRAP) assays. Mugwort was among the vegetables charted in that study. The researchers found that phenolic compounds, including plant flavonols such as quercetin, myricetin, and rutin, act as powerful antioxidants when compared with traditional vitamins. Chinese cabbage, onion, mugwort, broccoli, and chili pepper were named as potent examples of flavonoid-rich foods.
How is mugwort used for digestion?
Mugwort may relax the digestive tract and bile ducts when taken orally and may increase bile production. A desktop guide to herbal medicine lists cholagogue and choleretic actions among mugwort’s herbal properties, describing them as promoting bile flow from the liver and stimulating bile production, respectively. The report noted that more research is needed on mugwort as a digestive aid.
What about menstrual and blood pressure uses?
Some people use mugwort for irregular or painful periods, including amenorrhea (absent menstruation) and dysmenorrhea (painful menstruation). A separate text, “Botanical Medicine for Women’s Health,” addresses antimicrobial herbs in the context of women’s health concerns.
Mugwort might also lower blood pressure when used in moxibustion, though more research is needed. Moxibustion stimulates acupuncture points by igniting sticks or a cone of dried moxa herb (Artemisia vulgaris) and holding it close to the skin to produce a warming effect.
What forms is mugwort available in?
Mugwort is sold as an extract, tincture, dried leaves, essential oil, powder, tablets, capsules, and soft gels. Limited research exists on dosage, so users are generally advised to follow the product label or consult a doctor.
What safety risks should you know about?
- Allergic reactions. The primary risk of consuming mugwort is an allergic reaction, particularly in individuals hypersensitive to plants from the Asteraceae family, which includes chamomile, feverfew, ragweed, and mugwort.
- Pregnancy and breastfeeding. Mugwort should not be taken during pregnancy or breastfeeding.
- Diabetes and insulin resistance. People with these conditions should talk with a doctor, because mugwort can increase blood sugar.
- Thujone content. Mugwort contains thujone, which is toxic and can be fatal in large doses. Oral use should be avoided, or thujone-free supplements chosen.
How strong is the evidence overall?
Herbal practices involving mugwort have been refined over thousands of years, supporting continued interest in its traditional use for digestion, menstruation (including amenorrhea and dysmenorrhea), and skin conditions such as those mentioned above. Researchers note that clinical evidence for these uses remains thin, and most claims still require more rigorous study.

What is mugwort used for in herbal medicine?
Mugwort has traditionally been used for digestion, menstrual regulation (including amenorrhea and dysmenorrhea), skin conditions, and as the moxa herb burned in moxibustion.
Does mugwort have antioxidant properties?
Yes. A study in the Journal of the Science of Food and Agriculture measured antioxidant activity in mugwort using TEAC and FRAP assays and attributed the effect to phenolic compounds including quercetin, myricetin, and rutin.
Is mugwort safe to take?
Mugwort can cause allergic reactions, especially in people sensitive to Asteraceae plants such as ragweed and chamomile. It should not be taken during pregnancy or breastfeeding, people with diabetes or insulin resistance should consult a doctor because it can raise blood sugar, and it contains thujone, which is toxic in large doses.
