Try an alternative to mouthwash. What natural herbs help freshen breath? Try out parsley, basil or coriander. These herbs contain chlorophyll, the green plant pigment, which serves as a strong breath freshener.
Here are some others:
Anise: This is a licorice-flavored herb whose seeds have been used for a long time to freshen breath.
Cardamom: This contains cineole, which is a potent antiseptic that kills the bad breath-causing bacteria. You can chew the seeds and spit them out.
Dill: also rich in chlorophyll. You can chew the seeds, or make dill tea by adding mashed seeds or the leaves to boiling water.
Peppermint tea: This is an antiseptic that gets rid of bad breath as well.
