Gargling with Salt Water Actually Helps a Cold or Cough

Excerpt:

According to the editor of The Mayo Clinic Book of Home Remedies, warm salt water circulated at the back of the throat does two things to help cold sufferers:

A saline solution can draw excess fluid from inflamed tissues in the throat, making them hurt less, said Dr. Philip T. Hagen ... (He also) pointed out that gargling also loosens thick mucus, which can remove irritants like allergens, bacteria and fungi from the throat.

Comment: This works for me along with a saline solution nasal spray.
