Jim's chemo nurse gave him this recipe during his treatments. I kept a jug filled with this mouthwash and he used it daily. He never got any mouth sores. He is now considered cured of his cancer. This mouthwash has also been effective as a treatment for mouth sores.
To treat and/or prevent mouth sores:
Mix:
1 quart water
1 teaspoon salt
1 teaspoon baking soda
Pour mouthwash into cup and swish around in mouth then spit out (do not swallow). Repeat until liquid in cup is all used up. Use 4 times a day.
