Fennel is an excellent mouth freshener that can help eliminate bad breath. Fennel seeds are packed with certain antimicrobial properties that can be very effective in fighting the bacteria which develops in the mouth.
Since the seeds are easily chewable, simply pop a few into the mouth and chew on to freshen breath and stimulate saliva production in the mouth. As an alternative a tea made from fennel seeds can also be consumed a couple of times a day to prevent bad breath from returning. To prepare, steep one teaspoon of fennel seeds in a cup of hot water for 5-10 minutes before drinking.
