Mint is widely attributed with anti-inflammatory properties, thanks to its strong antioxidant action. Much like chamomile and green tea, rinsing with a mint-infused solution has been found to help ease swelling and counteract bleeding gums.
Specifically, the compound menthol, found in mint, seems to help kill bacteria in the mouth and prevent gingival bleeding. You can make a mint rinse by letting mint tea cool, then rinsing with it. This isn't recommended as a replacement for mouthwash, but to reap the benefit of mint on a daily basis, look for mouthwashes that contain menthol.
How to Enjoy It: Steep mint leaves or a mint tea bag in hot (but not boiling) water for up to 5 minutes, covered. Allow the liquid to cool completely, then swish and rinse as you would with any mouthwash.
