WHY does gargling with salt water cure a sore throat?

Gargling with salt water is a common treatment for sore throats. According to otolaryngologists, gargling with a solution consisting of half a teaspoon of salt and a quarter cup of warm water relieves the pain caused by inflammation. Similarly, if soda is added to salt water, the solution can break down dense mucus.

The solution cleanses the mouth, temporarily washing away bacteria and pus.
