Peppermint

Part of the mint plant, the effectiveness of peppermint in relieving various symptoms associated with irritable bowel syndrome (IBS) has been well-documented. Researchers have attributed its relief of IBS symptoms, such as constipation and bloating, mainly to its antispasmodic properties. It contains menthol which has a relaxing effect on the intestinal smooth muscle. Similarly, in a recent study on peppermint in the form of an enteric-coated supplement for the treatment of IBS-associated pain, researchers found that it had a pain-relieving effect for most IBS participants in the study, again attributed to its antispasmodic effect.
