Horehound drops, lozenges or candy sticks. My mother swore by these. I don't remember them tasting great, but I do remember them working. I've seen the drops and candy sticks at Cracker Barrel. I would think health food type stores would have them, too.
Xclear nasal spray and oil of oreganol p73 follow the directions on the label. They can be purchaed at your local vitamin store. Drink a lotof water too...helps a lot ..if you have a fever then best to probably see an ENT.
