"Mugwort has a long history of use in herbal medicine especially in matters connected to the digestive system, menstrual complaints and the treatment of worms[238]. It is slightly toxic, however, and should never be used by pregnant women, especially in their first trimester, since it can cause a miscarriage[7, 238]. Large, prolonged dosage can damage the nervous system[268]. All parts of the plant are anthelmintic, antiseptic, antispasmodic, carminative, cholagogue, diaphoretic, digestive, emmenagogue, expectorant, nervine, purgative, stimulant, slightly tonic and used in the treatment of women's complaints[4, 7, 13, 21, 147, 165, 178, 201]"

"The plant might be poisonous in large doses[21]. Skin contact can cause dermatitis in some people[222]. Probably unsafe for pregnant women as it may stimulate the uterus to contract and induce abortion [301]"

"The young shoots are used in spring[46]"

"The stem is also said to be antirheumatic, antispasmodic, and stomachic[218]. The compressed dried leaves and stems are used in moxibustion[176, 178, 218, 222, 238]"

"The roots are tonic and antispasmodic[243]. They are said to be one of the best stomachics[4]. They are harvested in the autumn and dried for later use[4]"

"Leaves - raw or cooked[2, 9, 12, 27, 177]. Aromatic and somewhat bitter[244]. Their addition to the diet aids the digestion and so they are often used in small quantities as a flavouring, especially with fatty foods[183, 244]. They are also used to give colour and flavour to glutinous-rice dumplings (Mochi)[183, 244]. In Japan the young leaves are used as a potherb[183]. The dried leaves and flowering tops are steeped into tea[183]. They have also been used as a flavouring in beer, though fell into virtual disuse once hops came into favour[4]."

"The leaves are also said to be appetizer, diuretic, haemostatic and stomachic[176, 218, 222]. They can be used internally or externally[218]. An infusion of the leaves and flowering tops is used in the treatment of nervous and spasmodic affections, sterility, functional bleeding of the uterus, dysmenorrhoea, asthma and diseases of the brain[176, 243]. The leaves have an antibacterial action, inhibiting the growth of Staphylococcus aureus, Bacillus typhi, B. dysenteriae, streptococci, E. coli, B. subtilis, Pseudomonas etc[176]. The leaves are harvested in August and can be dried for later use[4]. The leaves, placed inside the shoes, are said to be soothing for sore feet[238]. The compressed dried leaves and stems are used in moxibustion[176, 178, 218, 222, 238]. Another report says that the down from the leaves is used[4]"
