Peppermint Oil for IBS? -- Bottle of peppermint oil and capsules and peppermint leaf

Answer:

Many people share your reluctance to rely on drugs for irritable bowel syndrome (IBS), a common gastrointestinal disorder that causes chronic abdominal pain and altered bowel habits (diarrhea, constipation, or alternating bouts of both). Other non-pharmaceutical interventions for IBS — notably the low FODMAP diet, cognitive behavioral therapy, and gut-directed hypnotherapy — have performed well in clinical trials, but the time and commitment they require can be difficult for some people.

Peppermint oil is one of several supplements that have been proposed to help with IBS, possibly by reducing muscular spasms in the colon. However, the evidence to support its use is mixed. Sign in to see the full answer, and find out if experts recommend peppermint oil for kids and teens with IBS.

Peppermint oil may be helpful for mild indigestion and stomach upset in people who do not have IBS, as well as for other uses.
