Herbs contain essential oils that are powerful breath fresheners. Mint can clear the palette just by chewing on a couple leaves or drinking a mint tea. Anise Seeds have a nice, licorice flavor that freshens the mouth. Cardamom Pods - can help freshen breath, but do not swallow. Parsley contains an enzyme that can help clear odor causing particles. It also cuts the taste and smell of onions and garlic. Chew after a meal. Coriander - If mint or parsley are not appealing, try coriander which has a lemony flavor.
