Question

though sucking zinc lozenges has been promoted as a treatment for the common cold, research has revealed no consistent effect. recently, however, a zinc gel applied nasally has been shown to greatly reduce the duration of colds. since the gel contains zinc in the same form and concentration as the lozenges, the greater effectiveness of the gel must be due to the fact that cold viruses tend to concentrate in the nose, not the mouth.
