What is better for strep or a sore throat.... Gargle with warm salt water or warm baking soda water? I tried diluted poroxide water, too much foam.

Peroxide best. I recommend half- strength peroxide to my patients. Instead of gargling take half a mouthful and lean back and swish the solution for a minute or two before spitting it out. Repeat 2 additional times. Peroxide has antiseptic properties which is helpful during an infection.
