Medicated Cough Drops

Medicated cough drops have some effect. The 'Menthol' compounds are local anesthetic agents which can temporarily "numb" the nerves in the throat that are irritated by the cold symptoms and provide relief. Although medicated cough drops help, you do not want to use them if you are a singer because they will dry the vocal cords. You will most likely want to use a Ricola because they are non mentholated and they oil the vocal cords.
