Coltsfoot Interactions Overview

Coltsfoot (Tussilago farfara) is a perennial herb native to Europe and Asia and named for its leaves, which resemble the shape of a calf's foot. It has round, bright yellow flowers which resemble small dandelions, although it is not related to them. Coltsfoot has been used in traditional medicine for centuries for its purported expectorant and anti-inflammatory effects, which may help to loosen mucus and ease breathing. It is important to note that Coltsfoot may contain liver-toxic pyrrolizidine alkaloids. Repeated exposure could potentially cause harm. It is important to only utilize dietary supplements that have removed these harmful compounds.
