Coltsfoot

Coltsfoot is used for bronchitis, cough, and sore throat; but because it contains alkaloids that can damage the liver and cause cancer, its use is not recommended.

It's best to seek another remedy instead of using Coltsfoot. Make sure that any preparation you take delivers no more than 1 milligram of toxic pyrrolizidine alkaloids and N-oxides on a daily basis. No drug interactions have been reported. This information is for educational purposes and should not replace discussions with your doctor.
