Fennel
The plant fennel, which is closely related to foods like carrots, celery, and parsley, is prized for its distinct licorice-like flavor. Interestingly, research indicates that fennel and its seeds have antispasmodic properties, which means they can help to relax the muscles in your intestinal tract to relieve gas and bloating.
According to a June 2016 study published in the Journal of Gastrointestinal and Liver Diseases, fennel seed essential oil can help lessen IBS symptoms like flatulence and GI spasms. Just remember that the type of fennel you consume might make a significant difference. However, fennel tea includes fructans, a common IBS trigger, despite studies showing that fennel essential oil can reduce IBS symptoms. Ask your doctor about taking supplemental fennel for bloating if you are aware that you are sensitive to FODMAPs.
