This one is dedicated to Mr. FS: he has been gargling with salt water, lo these many years. Most of the other old wives' remedies to which he subscribed have been proven false. But this one has been endorsed by no less than the New York Times.
According to the Mayo Clinic, for best results, dissolve half a teaspoon of salt in a full glass of warm water and gargle the solution for a few seconds before spitting it out. Adults who want a more palatable remedy against cough and sore throat can try mixing warm water with lemon and honey. No need to spit it out.
THE BOTTOM LINE Gargling with a saline solution can ease symptoms of a cold.
Oh, how I love when the frugal way is the good way.
