Sore throat remedy: Salt and water
Try grandma’s sore throat remedy by mixing 1⁄4 teaspoon salt in 1 cup warm water. (Use the hottest water you can comfortably tolerate. Cold gargles are ineffective.) If you have it, add 1 tablespoon of Listerine for germ-killing power. The briny solution helps rinse away and neutralize acids in the throat, relieving the burning sensation and promoting fast healing of irritated mucous membranes.
Note: Mix a fresh batch of gargle for every use. Better to waste a bit pouring it out than to leave it in your glass, where it might become contaminated with bacteria. Also, do not swallow the gargle; spit it out.
