Irritable bowel syndrome (IBS) can be a terrible trial. Up to one in five individuals suffers with this chronic condition for which there is no cure (JAMA, March 3, 2015). People with IBS may experience abdominal pain, diarrhea, constipation or occasionally both (alternating). Doctors used to classify it as a “functional disorder, meaning they could find nothing anatomically or physiologically amiss. Consequently, they put relatively little effort into helping patients with their IBS symptoms. Fortunately, that is gradually changing.

Managing IBS Symptoms:

Q. I used a recipe for fennel tea that I found on your website. It really does help me with gas.

I have a problem with irritable bowel syndrome (IBS). The doctor didn’t have anything to prescribe but suggested I use IBgard. It’s ok, but I’d rather use a nondrug approach. What can you recommend?

Enteric-Coated Peppermint Oil:

A. IBgard contains enteric-coated peppermint oil. An analysis of twelve randomized controlled trials found that peppermint oil, a natural product, is safe and effective for IBS (BMC Complementary and Alternative Medicine, Jan. 17, 2019).  The most recent placebo-controlled study found that only peppermint oil designed to be released in the small intestine reduced abdominal pain and other IBS symptoms (Gastroenterology, Jan. 2020).


Some studies have found that various forms of exercise can reduce IBS symptoms (Neurogastroenterology and Motility, Feb. 2019). If you want to try a nondrug approach, you might consider daily walking or a regular practice of tai ji or qigong. Another possibility is a low FODMAP diet that cuts out foods that are readily fermented by bacteria in the digestive tract.


A systematic review found a small amount of evidence supporting the use of homeopathy, specifically asafoetida (Cochrane Database of Systematic Reviews, Nov. 13, 2013). We are not aware of any studies comparing homeopathic asafoetida to peppermint oil.
