Gargling:
Use boiled water or a sage infusion (1/2 cup) plus 1 drop of 5% Lugol’s solution. You can enhance the effect by adding: 1/2 teaspoon of salt, 1/2 teaspoon of hydrogen peroxide, or 1/2 teaspoon of apple cider vinegar. You may add all together or just one ingredient. Gargle at least 2–3 times a day.
