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
Appetite stimulant for loss of appetite (approved use under German Commission E)
Bitter digestive / stomachic for indigestion and dyspepsia (stimulates saliva and gastric secretion)
Bitter digestive / stomachic for indigestion and dyspepsia (stimulates saliva and gastric secretion)
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

Safety, Cautions & Contraindications
As a member of the daisy family (Asteraceae/ragweed), it can cause allergic reactions in sensitive people; high doses reportedly cause stomach cramps, nausea and vomiting.
Avoid during pregnancy because of a traditional uterine-stimulating reputation.
Although traditionally used to support milk supply, there is no scientifically valid clinical evidence for the galactagogue use.
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.

Botanical Description
Branching annual herb with a hairy, reddish, ridged stem and spiny, deeply lobed leaves with prominent pale veins. The flower heads are pale yellow, thistle-like, surrounded by a whorl of spiny, leaf-like bracts, giving the plant its 'spotted thistle' appearance.[4]
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
Grows on dry, sunny waste ground, roadsides and rocky slopes; native to the Mediterranean region and Western Asia and naturalised elsewhere as a garden escape.[4]
Grows in damp meadows, pastures, roadsides and woodland margins on moist, rich soils; native to Europe and Western Asia and naturalised in North America.[12]
Harvesting
The flowering aerial parts are cut as the plant comes into flower, in summer, and dried in a warm, shaded, airy place to preserve the bitter principle cnicin.[4]
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
Blessed thistle has a long European folk reputation as a bitter digestive tonic for loss of appetite and dyspepsia (an approved use under German Commission E) and, more anecdotally, as a traditional galactagogue to support breast-milk supply, though robust clinical evidence for the latter is lacking.[4, 11]
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
Traditional herbal references suggest around 1-2 g of dried herb per cup, taken before meals, up to three times daily. Educational reference only, not a prescription.
