Peppermint oil has long been thought to be helpful in reducing the symptoms of irritable bowel syndrome (IBS). Here is what you need to know before you try this time-honored remedy.

Why Peppermint Oil?

Peppermint oil is thought to have a helpful effect on gut motility. The principal component of peppermint oil is menthol, which appears to relax smooth muscle such as that found throughout the colon. This effect on the smooth muscle is thought to act to reduce gut spasms.

Does It Help IBS?

A number of research studies have been conducted to assess whether or not peppermint oil is better than a placebo in reducing IBS symptoms. In general, there has been some indication that peppermint oil is as effective as prescription antispasmodics, leading the American College of Gastroenterology to recommend peppermint oil as a front-line treatment.

Side Effects

Peppermint oil is generally well tolerated, although there are some reports of heartburn or burning sensations in the rectal area. In order to reduce side effects and to maximize effectiveness for IBS, enteric-coated capsules are your best bet.

Safety for Children

There is one study that found that children who suffered from IBS experienced significantly less abdominal pain after two weeks of taking peppermint oil supplements. The results were dramatic, with 75% of the children experiencing pain relief.


As with any remedy, it is best to get clearance from your physician. They are likely to recommend that you take two capsules twice a day.

Bottom Line

The fact that IBS is a chronic disease calls for caution when considering the use of prescription medication, due to concerns about long-term safety. Effective supplements thus become an important aspect of treatment. Peppermint oil would appear to fit the bill, in terms of providing a safe, well-tolerated treatment option for reducing IBS symptoms.
