Saltwater gargle. Several studies have found that gargling several times a day with warm salt water can reduce swelling in the throat and loosen mucus, helping to flush out irritants or bacteria. Doctors generally recommend dissolving half a teaspoon of salt in one cup of water.

Answer:
In addition to neutralizing acid, the salt water gargle helps to wash away unwanted mucus and increase the blood flow to the throat. The capillaries then become dilated, which allows for faster circulation of infection-fighting cells.
