When I was a kid, my mom used to insist that I gargle with warm salt water when I had a sore throat. I hated it. I hated it so much that I wouldn't tell her my throat hurt until it hurt so much that I couldn't stand it.
Today though, I am older and wiser. ;-)
Warm salt water is a cure for many ails. I use it in a Neti Pot most days and gargle with it at the first hint of a sore throat.
For example, I woke up (very) early Thursday morning with a terrible sore throat. I pretended it wasn't there and tried to go back to sleep. After an unsuccessful hour, I got up and prepared my gargling water... warm, not hot, stirred in a teaspoon of salt, took a mouthful, tipped my head back and gargled. I gargled a few times and attempted to sleep again until it was time for work.
I still got an awesome cold that has had me sidelined for most of this New Year holiday, but I do not have a sore throat. :-D
