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).
Anti-inflammatory iridoids contributing to the plant's traditional respiratory and anti-inflammatory use.
Mucilage gives the soothing demulcent action; saponins contribute to the traditional expectorant effect.
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
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.
Generally considered safe for short-term use. The tiny hairs on the leaves can cause irritation if tea is not properly filtered. No significant drug interactions documented. Not recommended during pregnancy or breastfeeding due to lack of safety data.
Duke (2002) rates mullein as ++ with clinical evidence (score 2) for its expectorant activity, consistent with Commission E approval for catarrh and inflammation of the respiratory tract. It functions as a demulcent and emollient for mucous membranes. Traditionally used for bronchitis, asthma, and earaches (oil infusion). Dose: 1.5–2 g dried flower or leaf as tea, three to four times daily. Duke notes an antiviral (antiherpetic) activity at the experimental level. The plant is generally well-tolerated with no known significant contraindications at therapeutic doses (Duke, 2002).

Botanical Description
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]
Tall, stately biennial herb forming a low first-year rosette of large, soft, thick, densely woolly grey-green leaves; in the second year it sends up a single, tall, unbranched flowering spike densely packed with bright yellow, five-petalled flowers that open a few at a time.[1]
Habitat
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]
Grows on dry, sunny waste ground, roadsides, disturbed soil and rocky slopes; native to Europe, North Africa and Asia and widely naturalised in North America and elsewhere.[1]
Harvesting
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]
The flowers are picked individually as they open through summer (since they open only a few at a time and quickly fade once picked); leaves are gathered from the first-year rosette or second-year plant and dried, with care to filter out the fine leaf hairs, which can irritate the throat if not strained from tea.[1]
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]
Great mullein has a long European and Native American tradition as a soothing demulcent and expectorant remedy for cough, bronchitis and irritated airways, and the flower has also been infused in oil as a traditional remedy for earache; the soft, woolly leaf gave rise to old names like 'flannel leaf' and 'velvet plant'.[1, 2]

Dosage
Not documented
The EU herbal monograph gives 1.5-2 g of the flower in 150 mL of boiling water as an infusion, three to four times daily (daily dose 4.5-8 g), in adolescents, adults and elderly; the infusion should be carefully strained to remove the irritant hairs. The monograph covers the FLOWER (Verbasci flos) only — it gives no posology for the leaf. Not recommended under 12 years. Educational reference only, not a prescription.
