Evidence face-off — shared uses
| Condition | Lesser Burdock | Tansy | Verdict |
|---|---|---|---|
| Arthritis / joint pain | 1/10 | 1/10 | Comparable evidence |
| Inflammation (general) | 1/10 | 1/10 | 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
The major storage carbohydrate; a prebiotic fibre.
Anti-inflammatory and antioxidant constituents.
Antimicrobial and antioxidant 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
Traditional 'alterative' / depurative for chronic skin conditions - eczema, psoriasis, acne and boils (internally and topically)
Lesser burdock (Arctium minus) leaf, flower and root extracts (rich in arctiin/arctigenin and chlorogenic acid) are cytotoxic to breast and liver cancer cells, including multidrug-resistant tumour lines (preclinical).
Traditional & Indicated Uses
Sebaceous-gland regulator - helps balance skin oil (acne); Traditional 'alterative' / depurative for chronic skin conditions - eczema, psoriasis, acne and boils (internally and topically)
inferred from anti-inflammatory action
Arctium minus extracts show dose-dependent cytotoxicity against MCF-7 and MDA-MB-231 breast cancer and HepG2 liver cancer cells and are active against both sensitive and multidrug-resistant tumour cell lines (preclinical).
Mild diuretic supporting elimination ('detox', traditional); Traditional 'alterative' / depurative for chronic skin conditions - eczema, psoriasis, acne and boils (internally and topically)

Safety, Cautions & Contraindications
As a member of the daisy family (Asteraceae), it can cause allergic reactions in people sensitive to ragweed and related plants. The high inulin content can cause temporary bloating or gas.
May lower blood sugar (caution with antidiabetic medicines) and add to diuretics; avoid medicinal doses in pregnancy.
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 For information and historical reference only — do not use internally.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
Biennial herb closely related to greater burdock, forming a first-year rosette of large, heart-shaped, long-stalked leaves, green above and grey-woolly beneath, generally smaller than Arctium lappa. In the second year it produces a branching flowering stem with smaller purple thistle-like flower heads in a looser, more sprawling habit, each enclosed in a globe of hooked bracts that ripen into clinging burrs.[15]
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
A common weed of waste ground, roadsides, hedgerows and disturbed soil; native to Europe and widely naturalised in North America, where it is often the most common wild burdock species.[15]
Native to Europe and temperate Asia, widely naturalised elsewhere; grows on roadsides, waste ground, riverbanks and disturbed grassland.[11]
Harvesting
The root is dug at the end of the first growing season or early in the second spring, before flowering; leaf may be gathered through the first year. Careful identification against deadly nightshade, whose root can resemble burdock, is essential before digging.[15]
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
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]

Dosage
Not documented
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.
