Key Constituents
The antimicrobial and anti-inflammatory principles of the root; the eudesmane core and the alpha,beta-methylene-lactone ring are essential for the antimicrobial activity.
A fructan polysaccharide abundant in the root (the genus Inula gives inulin its name).
Pharmacological Actions
Anti-inflammatory - sesquiterpene lactones (alantolactone, isoalantolactone) inhibit NF-kB and MAPK signalling and pro-inflammatory cytokines; total sesquiterpene lactones eased arthritis in animal models (potential in rheumatoid arthritis)
Antimicrobial, notably anti-staphylococcal (membrane-damaging) and anti-mycobacterial (active against Mycobacterium tuberculosis in vitro); supports respiratory and skin infection
Traditional & Indicated Uses

Safety, Cautions & Contraindications
Contains cardiac glycosides: do NOT use in pregnancy, breastfeeding or infancy, in anyone with a heart condition, or alongside cardiac glycoside medicines (e.g. digoxin). The plant's cardenolide-rich latex is directly toxic - a documented case caused corneal injury through Na/K-ATPase inhibition.
Large doses are emetic and purgative (cause vomiting and diarrhoea). There is very little modern safety or efficacy data, so use only under the guidance of a qualified practitioner.
The sesquiterpene lactones (especially alantolactone) are known skin sensitisers and can cause allergic contact dermatitis; people sensitive to the daisy family (Asteraceae) should be cautious.
Large doses can cause nausea, vomiting and diarrhoea; safety in pregnancy and breastfeeding is not established, so avoid medicinal doses.
External Ids
Botanical Description
Erect perennial herb with hairy, unbranched stems and narrow, lance-shaped, alternate leaves (unlike most milkweeds, its sap is clear rather than milky). Vivid orange-red flowers are borne in showy, flat-topped umbel-like clusters at the stem tips, making it a prized butterfly and pollinator plant. The stout, fibrous, branching root is the medicinal part.[11]
Tall, robust perennial herb with large, coarse, hairy leaves - broadly oval near the base and progressively smaller up the stem - arising from a thick, aromatic rhizome. Large, shaggy, bright yellow daisy-like flower heads with numerous narrow ray florets are borne at the top of stout, branching stems.[12]
Habitat
Harvesting
The root is dug in autumn after the plant has finished flowering and seeding, then cleaned and dried; given its cardiac glycoside content and near-absence of modern safety data, harvesting and use should only be undertaken with expert guidance.[11]
The root and rhizome are dug in autumn of the second or later year, when sesquiterpene lactone and inulin content is highest, then cleaned, sliced and dried.[12]
Traditional Uses
Elecampane root has a long European tradition, reflected in the old name 'elf dock', as a warming expectorant remedy for productive cough, bronchitis and chronic respiratory catarrh, and topically and internally as an antimicrobial for skin and wound infections.[12]
Preparations
Dosage
Because the root contains cardiac glycosides and modern safety/efficacy data are very limited, no general dose is given here; use only under the guidance of a qualified practitioner, and never in pregnancy, breastfeeding, infancy, or with a heart condition or cardiac glycoside medicines. Educational reference only, not a prescription.
