In one of my searches when my firstborn was a baby, I ran across a great home remedy for sore throats. I do not remember where I found this information, but it seems to be a fairly well known remedy so I feel comfortable posting this without any reference.
The easiest, cheapest, remedy for a sore throat? A spoon full of honey. My husband hates honey but decided to give it a try the other day since he was feeling desperate. You should have seen the look on his face a minute later. He looked at me like I had just come up with a magic cure for something. He couldn't believe taking the pain away could be that easy. So next time your sick, give it a try!
