Evidence scores (1–10) are computed from the tier of each cited source. “Comparable” means the two scores are within one point. Follow a score to its detailed sources.
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).
Improves glycemic control in type 2 diabetes - lowers fasting blood glucose and HbA1c
Anti-inflammatory and antioxidant; Hepatoprotective / liver support (protects liver cells, antioxidant and antifibrotic)
Digestive support / mild dyspepsia (traditional)
Hepatoprotective / liver support (protects liver cells, antioxidant and antifibrotic); May improve liver enzymes and hepatic fat in non-alcoholic fatty liver disease (NAFLD); Supports liver recovery and 'detox' (traditional framing of the hepatoprotective action)
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).
Very well tolerated, even at high doses; the main effects are mild gastrointestinal upset (nausea, loose stools). As a member of the daisy family (Asteraceae), it can cause allergic reactions in sensitive people.
Has a low potential for drug interactions (little effect on liver CYP enzymes), but use caution with medicines that have a narrow therapeutic window. Human pregnancy data are limited, so use cautiously.

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]
Robust biennial (occasionally annual) thistle (Asteraceae), 30-150 cm tall. Leaves are glossy dark green with distinctive white marbled veining (the 'milk' of legend), spiny-margined and deeply lobed. Large, solitary, purple-pink thistle-type flower heads are surrounded by spiny bracts, followed by shiny, mottled brown-black seeds - the part used.[12]
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]
Native to the Mediterranean region, now naturalised worldwide on disturbed, sunny ground - roadsides, waste places and dry pastures - and widely cultivated commercially for its seed.[12]
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]
Seed heads are harvested once fully dry (late summer), and the seeds (fruit) are threshed out.[12]
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]
Milk thistle has a very long European folk-medicine tradition, documented since antiquity, as a liver tonic, and its seed extract, standardised to the flavonolignan complex silymarin, is one of the most extensively studied herbal hepatoprotectants. Modern research supports antioxidant, anti-inflammatory and liver-protective activity, with growing interest in metabolic/blood-sugar effects.[12, 13]
Preparations
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.
