If you're serious about combating bad breath, chase your meal with green tea or sip it throughout the day. Green tea helps keep your breath fresh because it has antibacterial compounds that fight the germs in your mouth. Up the ante by using a cinnamon stick to stir your tea; cinnamon has essential oils that fight stinky breath, too [source: Dellorto].
Mint, parsley, basil, cilantro and dill temporarily mask offending oral odors because they release scented essential oils when chewed or crushed. While these herbs offer a quick solution to rancid breath, they also contain high levels of chlorophyll that can provide long-term benefits.
Chlorophyll is the green pigment that allows plants to photosynthesize energy from light. It can also help neutralize internal body odors, thereby reducing the smells that emanate from the body -- including bad breath [source: Duke]. If you aren't interested in chewing on fresh herbs or steeping them to make a tea, you can ingest concentrated chlorophyll either as tablets or sublingual drops (which are drops placed under the tongue for absorption).
