Irritable Bowel Syndrome (IBS)

  • IBS pain can be difficult to manage, and peppermint oil seems to work at least as well as other recommended treatments on the market.
  • Peppermint oil has few side effects, except for maybe some minty burps, which are quite tolerable.
  • Peppermint oil seems to calm smooth muscle cell activity in the small intestine, thus providing a biological basis for understanding the clinical benefit to patients with irritable bowel syndrome.


  • Peppermint oil may cause or worsen pre-existing heartburn and anal burning.
  • Peppermint oil treats only the pain of IBS. Other IBS symptoms (such as heartburn, gas, stooling urgency, soft stool consistency or belching) need to be addressed by other means.

Before self treatment is initiated, a diagnosis of irritable bowel syndrome should be confirmed by a medical provider to make sure that more serious problems are not being overlooked.

DOSAGE:The correct dose for treating irritable bowel syndrome is 0.2 to 0.4 ml three times daily. Look for a gastric-coated capsule to decrease the likelihood of stomach upset.

CONCLUSION:We conclude that peppermint oil is a safe and effective product for the treatment of IBS pain. Remember to include it in your list of medications when you visit your doctor and other health care providers.
