Key Constituents
Responsible for the characteristic astringency.
Antioxidant and anti-inflammatory constituents.
Thujone is the neurotoxic, safety-limiting constituent responsible for tansy's real internal-use toxicity.
Contribute to the plant's bitter taste and antimicrobial activity.
Pharmacological Actions
Anti-inflammatory gargle (mild inflammation of the mouth and throat / sore throat)
Agrimonia eupatoria ethanolic extract is cytotoxic to breast, colon, lung and cervical cancer cells and inhibits the PI3K/Akt/mTOR pathway (preclinical/in silico).
Traditional & Indicated Uses
inferred from bitter-tonic action
inferred from anti-inflammatory action
Agrimonia eupatoria ethanolic extract shows dose-dependent cytotoxicity against MCF-7 (breast), HT-29 (colon), A549 (lung) and HeLa (cervical) cancer cells and inhibits the PI3K/Akt/mTOR/COX-2/MMP-2 axis (preclinical).
Astringent (relief of mild diarrhoea)

Safety, Cautions & Contraindications
Traditional-use indication only: if diarrhoea persists longer than 3-4 days, or symptoms of mouth/throat inflammation persist beyond about a week, a doctor should be consulted.
Use during pregnancy and breastfeeding is not recommended, as safety has not been established.
CAUTION: Tansy is considered toxic in medicinal doses and is NOT recommended for internal use. Thujone can cause convulsions, liver and kidney damage. Contraindicated in pregnancy (uterotonic and abortifacient). External use (as insect repellent) is generally safe. For information and historical reference only — do not use internally.
Duke (2002) rates tansy as ++ but emphasizes important safety concerns. The plant contains thujone (a neurotoxic ketone) and camphor, making it potentially toxic with internal use. Documented activities include emmenagogue, abortifacient (score 1), and insecticide. Duke strongly cautions against internal use except under professional supervision, noting that historical cases of tansy poisoning have resulted in convulsions and death. Topical use as an insect repellent is safer but should still avoid prolonged skin contact due to the essential oil's sensitizing potential. Strictly contraindicated in pregnancy (Duke, 2002).
External Ids
Botanical Description
Slender, downy perennial herb with a basal rosette of pinnately compound leaves and a single, unbranched, upright flowering stem. The leaflets are toothed, alternating large and small, and silvery-downy beneath. Small, five-petalled, bright yellow flowers are borne closely along a slender terminal spike (raceme), opening a few at a time from the base upwards, giving the old name 'church steeples'. After flowering, small bristly, hooked burrs form that cling to clothing and animal fur for dispersal.[13, 14]
Aromatic perennial herb (Asteraceae), 50-120 cm tall, with erect, reddish, ridged stems. Leaves are finely divided, fern-like and strongly camphor-scented. Flat-topped clusters of small, yellow, button-like flower heads lack ray florets (petals).[11]
Habitat
Native to Europe and temperate Asia, widely naturalised elsewhere; grows on roadsides, waste ground, riverbanks and disturbed grassland.[11]
Harvesting
The flowering aerial parts are cut in summer, at the start of flowering, and dried promptly in a warm, airy, shaded place.[13]
Flowering aerial parts are cut in summer, when in full flower, and dried for external/historical use; given this plant's real toxicity (thujone content) at internal doses, this record does not recommend or describe internal harvesting for medicinal consumption.[11]
Traditional Uses
Agrimony has a long folk history as an astringent remedy for mild diarrhoea, as a gargle for sore throats and mild mouth/throat inflammation, and as a mild bitter digestive tonic; it has also been applied topically to minor wounds and skin inflammation. It is officially recognised in the European Union herbal monograph for traditional use in mild diarrhoea and mild inflammation of the mouth or throat.[13, 14]
Tansy has a long European history as a strewing herb, insect repellent and, historically, an internal vermifuge and emmenagogue, but its thujone and camphor content make internal medicinal use unsafe by modern standards. Today it is used, with caution, mainly as an external insect repellent; the traditional internal uses are recorded here for historical reference only, not as a recommendation.[11]
Preparations
Dosage
The EU herbal monograph gives 1.5-4 g of the comminuted herb in 250 mL (or less) of boiling water as an infusion, 2-3 times daily, in adolescents, adults and elderly. As a gargle for mild oral or throat inflammation, 1.5 g in 150 mL of boiling water 2-4 times daily, or a decoction of 3-4.5 g in 250 mL 2-3 times daily. Educational reference only, not a prescription.
The EU herbal monograph gives 1-4 mL three times daily (orally, or as a gargle for oral and throat use). Educational reference only, not a prescription.
Tansy is NOT recommended for internal use at any dose given its thujone content and documented toxicity (convulsions, liver/kidney damage) - internal use recorded here is for historical reference only. External use (e.g. as an insect repellent) should avoid prolonged skin contact. Educational reference only, not a prescription; strictly avoid in pregnancy.
