For fast relief from dry, barking, spasmodic, croupy, tickling, mucousy, continuous coughs due to the common cold or inhaled irritants. (Note: A persistent cough may be a sign of a serious condition. If cough persists for more than one week, tends to recur, or is accompanied by fever, rash or persistent headache, consult a health care professional.) Can help some of the most difficult and resistant adult coughs as well. Some practitioners have found chronic coughs in children to be stress or emotionally related, so check those remedies when that may be a possibility.
