Key Constituents
Multiple undescribed and known sesquiterpenoids and triterpenoids isolated from the leaves, several with anti-inflammatory activity.
Volatile oil containing thujone and other monoterpenes; thujone content is the basis of the caution on prolonged internal use.
Antioxidant and anti-inflammatory flavonoid and coumarin constituents.
Pharmacological Actions
Artemisia vulgaris (mugwort) extracts inhibit BCR/ABL and induce apoptosis, ferroptosis and necroptosis in chronic myeloid leukaemia and breast cancer cells (preclinical).
Appetite stimulant for loss of appetite (approved use under German Commission E)
Bitter digestive / stomachic for indigestion and dyspepsia (stimulates saliva and gastric secretion)
Bitter digestive / stomachic for indigestion and dyspepsia (stimulates saliva and gastric secretion)
Traditional & Indicated Uses
inferred from anti-inflammatory action
Artemisia vulgaris (mugwort) extracts inhibit BCR/ABL and induce apoptosis in chronic myeloid leukaemia cells (including imatinib-resistant), and trigger tumour-selective ferroptosis/necroptosis in breast cancer and leukaemia cells via lysosomal Ca2+ signalling (preclinical).

Safety, Cautions & Contraindications
Contains thujone; avoid high doses or prolonged use. Contraindicated in pregnancy (uterine stimulant and abortifacient). May cause allergic reactions in individuals sensitive to the Asteraceae family. Avoid in epilepsy. Not recommended for children.
Duke (2002) rates mugwort as + (use with caution) and notes abortifacient (score 1), emmenagogue, aperitif (score 1), and insecticide activities. Duke clearly flags mugwort as contraindicated in pregnancy due to well-documented abortifacient and uterotonic properties. Traditional use has been as a digestive bitter, and the plant contains volatile oils, sesquiterpene lactones, and flavonoids. Duke notes that the plant may cause allergic reactions in individuals sensitive to Asteraceae and warns against long-term use due to potential neurotoxicity from thujone-containing essential oil (Duke, 2002).
As a member of the daisy family (Asteraceae/ragweed), it can cause allergic reactions in sensitive people; high doses reportedly cause stomach cramps, nausea and vomiting.
Avoid during pregnancy because of a traditional uterine-stimulating reputation.
Although traditionally used to support milk supply, there is no scientifically valid clinical evidence for the galactagogue use.

Botanical Description
Tall, aromatic perennial herb with deeply lobed, dark green leaves that are distinctively silvery-white and woolly beneath. Small, dull reddish-brown to yellowish flower heads are borne in dense, branched, leafy spikes. The reddish-brown, ridged stems and the leaf's contrasting silver underside are characteristic field marks.[3]
Branching annual herb with a hairy, reddish, ridged stem and spiny, deeply lobed leaves with prominent pale veins. The flower heads are pale yellow, thistle-like, surrounded by a whorl of spiny, leaf-like bracts, giving the plant its 'spotted thistle' appearance.[4]
Habitat
A common plant of waste ground, roadsides, hedgerows and riverbanks; native to Europe, Asia and North Africa and widely naturalised in North America.[3]
Grows on dry, sunny waste ground, roadsides and rocky slopes; native to the Mediterranean region and Western Asia and naturalised elsewhere as a garden escape.[4]
Harvesting
The flowering aerial parts (leaf and stem) are cut in summer as flowering begins and dried in a warm, shaded, airy place; the root can be dug in autumn.[3]
The flowering aerial parts are cut as the plant comes into flower, in summer, and dried in a warm, shaded, airy place to preserve the bitter principle cnicin.[4]
Traditional Uses
Mugwort is a widely used traditional bitter digestive tonic and calming nervine, and has a long reputation as an emmenagogue for menstrual complaints (reflected in its traditional use to bring on delayed menstruation, which is also why it is contraindicated in pregnancy). It has also been burned as 'moxa' in East Asian moxibustion and used as an insect repellent ('sailor's tobacco').[3]
Blessed thistle has a long European folk reputation as a bitter digestive tonic for loss of appetite and dyspepsia (an approved use under German Commission E) and, more anecdotally, as a traditional galactagogue to support breast-milk supply, though robust clinical evidence for the latter is lacking.[4, 11]
Preparations
Dried flowering herb infused briefly in hot water as a bitter digestive tea, taken before meals.
Dosage
Health Canada's NNHPD monograph gives 0.2-2.4 g of dried herb top, 3 times per day, for adults 18 years and older, with infusion and decoction among the accepted methods of preparation. Educational reference only, not a prescription.
Traditional herbal references suggest around 1-2 g of dried herb per cup, taken before meals, up to three times daily. Educational reference only, not a prescription.
