I'd like to know how to treat a wet cough after a viral infection.

Difficult: These annoying coughs occur when the lining of the throat is renewing itself. They are especially prevalent if you had laryngitis. Use of cough drops and cough syrup can help. Sometimes the use of antihistamines liike chlortrimetron can help. For immediate short acting stopping of the cough, cut a thin slice of fresh ginger, coat it with honey and then chew on it - gives remarkable relief.
