Other common names include tash plant, ass's foot, bull's foot, coughwort (Old English), farfara, foal's foot, foalswort and horse foot. Sometimes it is confused with Petasites frigidus, or western coltsfoot.
It has been called bechion, bechichie or bechie, from the Ancient Greek word for "cough". Also ungula caballina("horse hoof"), pes pulli ("foal's foot"), and chamæleuce.
Coltsfoot has been used in herbal medicine and has been consumed as a food product with some confectioneryproducts, such as Coltsfoot Rock. Tussilago farfara leaves have been used in the traditional Austrian medicine internally (as tea or syrup) or externally (directly applied) for treatment of disorders of the respiratory tract, skin, locomotor system, viral infections, flu, colds, fever, rheumatism and gout.
Coltsfoot is used as a food plant by the larvae of some Lepidoptera species including the gothic and small angle shades.
Tussilago farfara contains tumorigenic pyrrolizidine alkaloids.[14] Senecionine and senkirkine, present in coltsfoot, have the highest mutagenetic activityof any pyrrolozidine alkaloid, tested using Drosophila melanogaster to produce a comparative genotoxicity test. There are documented cases of coltsfoot tea causing severe liver problems in an infant, and in another case, an infant developed liver disease and died because the mother drank tea containing coltsfoot during her pregnancy. In response the German government banned the sale of coltsfoot. Clonal plants of colstfoot free of pyrrolizidine alkaloids were then developed in Austria and Germany. This has resulted in the development of the registered variety Tussilago farfara'Wien' which has no detectable levels of these alkaloids.
