Today I woke up with a cold, and I took all the cold medicines that I usually take this morning and in few minutes I am going back to bed. I did one other thing, though. Since I was a little boy, my mother taught me to gargle with salt water to ease my sore throat. While I trusted her back then, today I do it “just in case.” So the question is does this actually work? Will salt water kill the germs in my throat that are causing the sorness, or will it promote healing in some other way?
