Coltsfoot (Tussilago farfara) — Coughwort, Foal’s Foot
Materia Medica
Coltsfoot (Tussilago farfara) is a perennial herb of the Asteraceae family, native to Europe and Asia and naturalized in North America. Its bright yellow flowers appear in early spring before the large hoof-shaped leaves, and both have been used for centuries as a classic cough remedy.
Actions & Energetics
Cooling and moistening to the lungs, mildly astringent. The Latin name Tussilago means “cough dispeller.” Traditionally regarded as a demulcent and mild expectorant that soothes irritated respiratory passages. In TCM the flowers (Kuan Dong Hua) are used to moisten the lungs and stop cough.
Botanical Description
A low perennial that spreads by rhizomes. In late winter to early spring, scaly flower stalks emerge bearing solitary yellow composite heads before any leaves appear. After flowering, large heart- or hoof-shaped leaves develop on long petioles, woolly beneath. The plant prefers damp, disturbed ground such as stream banks and roadsides.
Traditional Indications
Soothing support for dry, irritating, or spasmodic coughs, bronchitis, and throat irritation. Historical use of the leaves as a smoked herb for respiratory complaints. External poultice of the leaves for minor skin irritation. Culinary use of young leaves and flowers in small amounts in some European traditions. Classic European cough syrup ingredient, often combined with horehound, marshmallow, or licorice.
Preparations & Dosage
Infusion of dried flowers or leaves: 1 tsp per cup, strained carefully to remove the fine hairs. Syrup prepared from a strong infusion sweetened with honey. Traditional smoked leaf for short-term respiratory use. External poultice of fresh or dried leaves. Modern use is generally limited to short-term applications because of the presence of pyrrolizidine alkaloids.
Constituents
Mucilage, flavonoids, tannins, and pyrrolizidine alkaloids (including senecionine and senkirkine). The mucilage contributes to the traditional demulcent effect. Pyrrolizidine alkaloids are the primary safety consideration for internal use.
Modern Research
Limited clinical studies exist. The traditional reputation as a cough soother is long-standing, but the presence of hepatotoxic pyrrolizidine alkaloids has led to restrictions on internal use in many countries. External and very short-term traditional preparations are the most common contemporary applications.
History, Folklore & Spiritual Use
Known since classical times; Dioscorides recommended smoking the leaves for cough. The early appearance of the flowers before the leaves earned the old name “son before the father.” In Chinese materia medica the flowers have been recorded since the Han dynasty. European folk names include coughwort and foal’s foot, reflecting both the medicinal reputation and the leaf shape. It remains one of the most historically significant respiratory herbs in the European tradition.
Summary
Coltsfoot is a classic early-spring cough herb whose demulcent reputation is well documented across European and Chinese traditions. Its distinctive flowering habit and long history of use for irritated respiratory passages make it a notable plant, though modern internal use is limited by the presence of pyrrolizidine alkaloids.
