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.
It’s been used for thousands of years in Asian medicine to treat stomachaches, diarrhea, and nausea, and studies show that it works for nausea and vomiting. There’s some evidence that it might help with menstrual cramps, too. But it’s not necessarily good for everyone. Some people get tummy trouble, heartburn, diarrhea, and gas because of it, and it may affect how some medications work. So talk to your doctor, and use it with care.
