In the United States, the use of coltsfoot is a subject of controversy, as it has been known to cause side effects that largely affect the liver.

Since the quantity of these toxins in the herb is less, side effects may occur or worsen only when the herb is consumed in large doses. Though moderate use of this herb may not cause serious health problems, it is recommended to refrain from its use or use it only under the supervision of a doctor.
