Gargling

Gargling is the act of bubbling liquid in the mouth.

It is also the washing of one's throat with a liquid (with one's head tipped back) that is kept from being swallowed by continuous exhalation.

Mouthwash or hydrogen peroxide (in a low concentration) is often employed.

[citation needed] A traditional home remedy of gargling warm saltwater is sometimes recommended to soothe a sore throat.

[1] One study in Japan has shown that gargling water a few times a day will lower the chance of upper respiratory infections such as common colds,[2][3] though some medical doctors are skeptical.
