Peppermint

According to the Memorial Sloan Kettering Cancer Center, peppermint includes an organic compound called l-menthol that has been demonstrated to lessen gastric and colonic spasms, relax the muscles of the GI tract, and possibly relieve stomach pain and bloating (MSKCC).

To lessen the risk of peppermint causing stomach acid reflux, make sure to select a product that is enteric-coated, which means it has a special coating that allows the peppermint to reach the small intestine. If you don't frequently get acid reflux, consider drinking a cup of peppermint tea the next time your stomach feels bloated. Herbal teas like peppermint tea are frequently used to treat a variety of digestive issues. Particularly peppermint oil has been demonstrated to reduce inflammation and treat IBS symptoms like bloating, constipation, and stomach pain.
