Coltsfoot is a botanical from the *Tussilago farfara* plant. Herbalists have long used it to soothe coughs and support throat comfort. You can find it as a liquid extract, glycerite, tea, or powdered herb.
Coltsfoot contains compounds called pyrrolizidine alkaloids (PAs) that can harm the liver. Avoid internal use for long stretches or at high doses. Do not take it if you are pregnant, nursing, or have liver disease.
