Mullein
Verbascum thapsus
Also known as: common mullein, Verbascum thapsus
A robust biennial introduced from Europe, naturalized across North America in disturbed soils, roadsides, old fields, and meadow edges. First-year plants produce a striking rosette of large soft fuzzy gray-green leaves (up to 18 inches long); second-year plants bolt to produce a tall (up to 8 ft) flowering spike bearing dozens of yellow flowers. Foundational respiratory herb in Western herbalism — leaves and flowers both used as expectorant, demulcent, and anti-inflammatory for bronchitis, dry cough, asthma, and other respiratory conditions. The leaves' velvety surface gave the plant its colloquial 'cowboy toilet paper' nickname; the leaves were widely used as primitive lamp wicks (the alternative folk name 'candlewick plant').
Scientific / medicinal
Verbascum thapsus is in the Scrophulariaceae (figwort family). The plant produces large basal leaves in year one (a rosette of fuzzy gray-green leaves up to 18 inches long), then bolts in year two to produce a tall flower spike bearing dozens of small yellow flowers that open progressively from bottom to top across the season.
Active compounds in mullein include mucilage (the principal demulcent, soothing-to-mucous-membranes compound), saponins (expectorant compounds that help thin and mobilize mucus), iridoid glycosides (anti-inflammatory), flavonoids, and verbascoside (a phenylethanoid with documented anti-inflammatory and antioxidant activity).
Documented and traditional uses:
- Respiratory conditions. The principal traditional use. Mullein is expectorant (helps mobilize and clear mucus from the respiratory tract), demulcent (soothes irritated mucous membranes), and mildly anti-inflammatory. Used for bronchitis, dry hacking cough, asthma support, and post-cold residual lung irritation. Available as tea (made from leaves and/or flowers — strain through fine cloth to remove the irritating leaf hairs), tincture, and inhaled smoke (in herbal smoking blends, the smoke has the unusual property of being soothing rather than irritating to the respiratory tract).
- Ear infections. Mullein flowers infused into olive oil produce a traditional ear-oil for otitis externa and otitis media (use under appropriate medical guidance for ear pain).
- Lymphatic decongestant. Traditional use for swollen lymph nodes in the neck and chest, particularly in the context of chronic respiratory infections.
Practical
Common preparation: dried leaves in tea (must be strained through fine cloth — the small hairs on the leaves are irritating to the throat); dried flowers in tea or oil infusion; tincture; smoking-herb blend.
The plant grows readily on poor disturbed soil; substantially abundant across North America. Wild-harvest is sustainable for the species — it is a widespread non-native naturalized plant, not a conservation concern.
