Coltsfoot (Tussilago farfara) has been traditionally used as a herbal remedy for cough and other respiratory ailments for centuries, particularly in European and Asian folk medicine. The leaves and flowers of coltsfoot contain mucilage, which is thought to soothe irritated mucous membranes, as well as small amounts of alkaloids and flavonoids that may contribute to its expectorant effects. Historical texts record its use as a tea, syrup, or lozenge to ease cough, bronchitis, and sore throat.

Despite its long-standing traditional use, modern scientific evidence supporting coltsfoot’s efficacy for cough relief is limited and generally considered insufficient. Few rigorous clinical trials have been conducted, and most studies are either animal-based or in vitro, focusing on possible anti-inflammatory or soothing effects. Furthermore, safety concerns exist due to the presence of pyrrolizidine alkaloids in coltsfoot, compounds that can be toxic to the liver if consumed in significant or prolonged doses. Some regulatory agencies have restricted or advised against its use for this reason. In summary, coltsfoot’s use for cough is primarily based on traditional practice, with only weak scientific support and notable safety concerns.
