Believe it or not, your toothbrush may be perpetuating—or even causing—your sore throat. Bacteria collect on the bristles, and any injury to the gums during brushing injects these germs into your system. As soon as you start feeling ill, throw away your toothbrush. Often that’s enough to stop the illness in its tracks. “Changing your toothbrush is often recommended for patients with bacterial throat infections to eliminate the spread of infection,” Dr. Abramowitz says.
Mint has been used for hundreds of years as a health remedy. Peppermint oil might help with irritable bowel syndrome -- a long-term condition that can cause cramps, bloating, gas, diarrhea, and constipation -- and it may be good for headaches as well. More studies are needed to see how much it helps and why. People use the leaf for other conditions, too, but there’s very little evidence it helps with any of them.
