Coltsfoot (Tussilago farfara)

Lungwort (Pulmonaria officinalis)

About

Coltsfoot is a perennial herb growing to 12 inches with flowering stems covered in purple scales, yellow-gold flowers, and heart-shaped leaves. Indigenous to Europe and northern Asia and naturalized in North America, it is commonly found along roadsides, on verges, and in open areas. The flowers are gathered in late winter, and the leaves in summer. For at least 2,500 years, coltsfoot has been taken as a cough remedy and smoked to ease breathing. The Greek physician Dioscorides in the 1st century CE recommended it for dry coughs and 'for those who are unable to breathe except standing upright.'

Lungwort is a perennial herb growing to 1 foot with broad oval basal leaves, smaller upper leaves mottled with white spots, and clusters of pink-purple flowers. Native to Europe and the Caucasus, it flourishes in mountain pastures and damp sites. The leaves are gathered in late spring. According to the medieval Doctrine of Signatures, which held that a plant's appearance pointed to the ailment it treated, lungwort was effective for chest ailments because its leaves were said to resemble lung tissue. This folk belief, while not scientifically founded, turned out to have merit - the herb is indeed valuable for respiratory conditions.

Safety & precautions

Do not use coltsfoot flowers. Do not take the leaves for more than 3-4 weeks at a time (or 6 weeks per year). Contains pyrrolizidine alkaloids, which may be toxic to the liver in higher doses, though these are largely destroyed when boiled to make a decoction. Do not take during pregnancy or while breastfeeding. Not suitable for children under 6. Subject to legal restrictions in some countries. Use only as directed.

Subject to legal restrictions in some countries. Pyrrolizidine alkaloids occur in the roots but in negligible quantities in the leaves, so the leaves are considered safe for medicinal use. Use only the leaves, not the roots.
