Help With Headaches
The active ingredient in peppermint is menthol. Some small studies show it can lessen the pain of migraine headaches.
It may also reduce other symptoms like light sensitivity, nausea, and vomiting. A few studies suggest that applying a peppermint oil solution to your forehead and temples can help take away tension headaches, too.
Kill Mouth Germs
Not only does the flavor of peppermint freshen your breath, but its antibacterial properties may also help get rid of the source of the smell: germs.
It’s believed to keep bacteria from forming a film on your teeth, which helps keep your pearly whites healthy.
