Plant Comparison
Mugwort vs Wild Lettuce
A side-by-side comparison of two medicinal plants — every documented constituent, action, use, safety note and cited source, assembled automatically from the Omnia Sana database.
At a glance
Mugwort and Wild Lettuce: both belong to the Asteraceae family; they share 1 indicated use (insomnia / sleeplessness); 1 pharmacological action in common.
Evidence face-off — shared uses
| Condition | Mugwort | Wild Lettuce | Verdict |
|---|---|---|---|
| Insomnia / sleeplessness | 1/10 | 2/10 | Comparable evidence |
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.
Bitter, centrally-active constituents responsible for the sedative and pain-relieving effects; isolated lactucin and lactucopicrin produced analgesia comparable to ibuprofen and sedation in rodent tests.
The historical medicinal preparation, concentrating the active lactones.
Pharmacological Actions
Artemisia vulgaris (mugwort) extracts inhibit BCR/ABL and induce apoptosis, ferroptosis and necroptosis in chronic myeloid leukaemia and breast cancer cells (preclinical).
Mild analgesic / anodyne for pain (lactucin and lactucopicrin act on the central nervous system) - in mice these compounds produced analgesia comparable to ibuprofen
Calming for nervous tension and restlessness
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).
inferred from digestive action

Antitussive for an irritable, dry cough (traditional)
Sedative for sleeplessness / insomnia - lactucin and lactucopicrin showed sedative activity in animal models
Calming for nervous tension and restlessness
Mild analgesic / anodyne for pain (lactucin and lactucopicrin act on the central nervous system) - in mice these compounds produced analgesia comparable to ibuprofen
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).
Can be unsafe in large amounts or if harvested too early: overdose can cause sweating, fast heartbeat, dilated pupils, dizziness, ringing in the ears, vision changes, heavy sedation, breathing difficulty and, in extreme cases, death.

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]
Tall, bristly biennial herb with a milky latex throughout, and prickly-edged, often blue-green leaves that tend to twist to align edge-on with the sun ('compass plant' habit). Small, pale yellow, dandelion-like flower heads are borne in loose branched clusters atop a tall, spiny-stemmed flowering stalk.[11]
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 waste ground, roadsides, hedgerows and disturbed soil; native to Europe, North Africa and Western Asia and naturalised in North America.
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 milky latex is traditionally collected by scoring the flowering stem and letting the exuded sap dry into lactucarium; the aerial parts (leaf and stem) are also cut and dried while the plant is flowering.[11]
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]
Wild lettuce has a long folk history, reflected in the name 'opium lettuce', as a mild sedative and analgesic remedy for insomnia, nervous tension and pain, and as an antitussive for irritable dry cough, its dried latex (lactucarium) once used as a milder, non-addictive alternative to opium.[11]
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.
Because of documented overdose toxicity (rapid heartbeat, heavy sedation, breathing difficulty), only conservative traditional herbal doses should be used and this herb should not be self-dosed at concentrated or extract strength without professional guidance. Educational reference only, not a prescription.
