A systematic review found that several antispasmodics, including peppermint oil, pinaverium, trimebutine, and cimetropium/dicyclomine, significantly outperformed placebo at improving irritable bowel syndrome symptom and global assessment scores. [33] Pinaverium and cimetropium are not available in the United States. The National Institutes of Health's (NIH's) National Center for Complementary and Integrative Health (NCCIH) provides information regarding a small amount of research that suggests peppermint oil may improve IBS symptoms.
