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.
The pungent alkaloid-like compounds responsible for the fruit's heat and its counterirritant/analgesic action via TRPV1 receptor desensitisation.
Give ripe red fruit its colour and contribute antioxidant and anti-inflammatory activity.
Antioxidant and anti-inflammatory flavonoids identified in leaf and fruit extracts.
Pharmacological Actions
Artemisia vulgaris (mugwort) extracts inhibit BCR/ABL and induce apoptosis, ferroptosis and necroptosis in chronic myeloid leukaemia and breast cancer cells (preclinical).
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).
Capsaicin causes intense burning sensation; avoid contact with eyes and mucous membranes. High oral doses can cause gastrointestinal irritation, nausea, and diarrhoea. Topical preparations may cause skin irritation and should be used diluted. Not recommended for individuals with active peptic ulcers. Caution with anticoagulants — capsaicin may enhance bleeding risk. During pregnancy, culinary amounts are considered safe, but high-dose supplements should be avoided. Repeated topical application leads to desensitisation (TRPV1 depletion), which is the basis for its analgesic use. Children under 2 should not be given capsaicin-containing topical products (Basu and Bhattacharyya, 2023).
Duke (2002) rates cayenne/chili pepper (Capsicum annuum) highly for its clinically documented analgesic, counterirritant, and rubefacient activities. Commission E approves topical capsaicin preparations for muscle pain, arthritis, and neuralgia (score 2). The active compound capsaicin depletes substance P in sensory neurons upon repeated application, reducing pain signals. Capsaicin cream (0.025–0.075%) is a validated treatment for post-herpetic neuralgia, diabetic neuropathy, and osteoarthritis pain. Internal use can irritate mucous membranes; external use requires avoiding contact with eyes and mucous membranes (Duke, 2002).
External Ids
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]
Bushy annual or short-lived perennial herb (grown as an annual in temperate climates) with glossy, oval to lance-shaped leaves. Small, star-shaped, white to greenish flowers give way to the characteristic fleshy, hollow fruit (a berry), which ripens from green through yellow to red and varies enormously in size, shape and pungency between cultivars.[1]
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 Central and South America; cultivated worldwide in warm and temperate climates as a food and medicinal crop, thriving in full sun on well-drained soil.[1]
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]
Fruit is picked at the desired stage of ripeness (green for milder use, fully red for maximum capsaicin and carotenoid content) through summer and autumn; seeds are separated and dried from fully ripe fruit.
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]
Chili pepper fruit has a long history across the Americas and, after global spread, in many other traditional medicine systems as a warming digestive stimulant and topical counterirritant/analgesic for muscle and joint pain, building on capsaicin's now well-documented ability to desensitise pain-sensing nerve fibres with repeated application.[1]
Preparations
Standardised capsaicin cream or patch applied to the affected area for muscle, joint or nerve pain; repeated application depletes substance P and reduces pain signalling.
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.
The EU herbal monograph on Capsici fructus gives semi-solid dosage forms corresponding to 40-53 mg capsaicinoids per 100 g, applied as a thin layer to the affected area 2-4 times daily, in adults and elderly. For medicated plasters, a maximum of 1 plaster per day applied for at least 4 and up to 12 hours, with at least 12 hours before a new plaster is applied to the same area. Not recommended under 18 years. Expect an initial burning sensation that lessens with repeated use. Note the monograph covers hot chilli fruit (C. annuum var. minimum and small-fruited C. frutescens), not sweet peppers. Educational reference only, not a prescription.
