Artemisia vulgaris
CautionBeifuß · (Artemisia vulgaris)
Daisy family (Asteraceae)
Description
Deeply lobed leaves with a silvery-white, felted underside, borne on reddish-tinged stems reaching up to two metres, characterise this daisy-family plant found along roadsides, wasteland and riverbanks across Central Europe. The flowering herb is harvested between July and September; depending on chemotype, its essential oil can contain up to 48 percent camphor along with cineole and beta-thujone. An infusion of the herb traditionally serves as a bitter tonic to stimulate digestive secretions for loss of appetite and flatulence, and it has traditionally been used as an emmenagogue for absent or painful menstruation. In traditional Chinese medicine, dried leaves are pressed into moxa sticks and burned for thermoacupuncture; in the kitchen, mugwort seasons fatty meats such as goose and duck. WARNING: strictly contraindicated in pregnancy due to possible uterus-stimulating effects. The thujone it contains is neurotoxic at high doses, so prolonged use is not advised; people with Asteraceae allergy face increased sensitisation risk.
CONTRAINDICATED during pregnancy
Pronounced uterotonic effect; can trigger uterine contractions and induce miscarriage. Strictly avoid.
CONTRAINDICATED during breastfeeding
Insufficient data; contraindicated as a precaution due to thujone content in essential oil.
CONTRAINDICATED for children
Due to thujone content and potential neurotoxic effects, do not use in children under 12 years.
Infusion of the flowering herb (1–2 g per cup) as a bitter tonic to stimulate digestive secretions for loss of appetite, flatulence, and dyspeptic complaints. Sesquiterpene lactones (vulgarin) and essential oils (1,8-cineole, camphor) are responsible for the bitter, carminative action.

Traditionally used as an emmenagogue for irregular, absent, or painful menstruation (dysmenorrhoea, amenorrhoea). The flavonoids eriodictyol and apigenin possess weak oestrogenic activity and can stimulate uterine contractions — therefore strictly contraindicated in pregnancy.

Dried or fresh leaves as a culinary herb with fatty meats (goose, duck), stuffings, and gruit ale. Essential oils stimulate fat digestion and bile secretion. Traditional culinary plant in Germany and Vietnam.
Warm herb poultice from freshly crushed leaves or moist tea infusion for joint pain and menstrual cramps. Topical use avoids absorption of larger amounts of thujone.
In traditional Chinese medicine, dried leaves and stems are compressed into moxa sticks and burned for thermoacupuncture (moxibustion) to stimulate acupoints. This application must be strictly distinguished from internal use.
Alcoholic extract from flowering herb as a bitter tonic; more concentrated than tea infusion. Due to thujone content, use only in small doses (max. 2–4 ml/day) and not continuously.
Used in folk medicine as an expectorant and antispasmodic for respiratory complaints and asthma. The essential oil with 1,8-cineole and anticholinergic properties show bronchodilatory effects (animal studies).

Strictly contraindicated during pregnancy (uterotonic effect — abortion possible). Thujone (β-thujone up to 1.19 % in essential oil) is neurotoxic in high doses; avoid prolonged use. People with Asteraceae allergy or Artemisia pollen allergy have increased sensitisation risk. Essential oil taken internally: not recommended. About the genus: The ASPCA lists tarragon (Artemisia dracunculus) as toxic to dogs and cats. Mugwort itself is not classified there — but the genus contains the same bitter compounds and terpenes. When in doubt, keep it away from pets.
⏱ Max continuous use: 4 weeks
Pronounced uterotonic effect; can trigger uterine contractions and induce miscarriage. Strictly avoid.
Insufficient data; contraindicated as a precaution due to thujone content in essential oil.
Due to thujone content and potential neurotoxic effects, do not use in children under 12 years.
Drug interactions
MAO-Hemmer (Moclobemid, Phenelzin)
Mugwort is attributed with MAO-inhibitory properties; possible additive effect with psychiatric MAO inhibitors.
Contraindications
- Pregnancy and lactation.
- Known allergy to the daisy family (Asteraceae), especially Artemisia pollen (cross-reactions possible).
- Epilepsy (thujone may lower seizure threshold).
Harvested part: flowering herb
- Time of day:
- Morning after the dew has dried; harvest upper shoot tips while flower heads are still closed (opening of flowers = leaves become more bitter and less aromatic).
- Drying:
- Spread thinly in a ventilated shed at max. 40 °C; remove stems as leaves are more aromatic.
- Storage:
- 12 months — Dry, protected from light, in airtight containers; essential oil evaporates with prolonged storage.
- Drying:
- Wash roots, slice, and dry at 40 °C until light and light-brown.
- Storage:
- 24 months — Store cool, dry and protected from light.
