Irritable bowel syndrome (IBS) is a common digestive disorder characterized by abdominal pain, cramping, and changes in normal bowel function, including bloating, gas, diarrhea, and constipation. About 12% of adults in the United States has irritable bowel syndrome (IBS). Other terms to refer to IBS may include spastic colon, spastic colitis, mucous colitis, nervous diarrhea, nervous colon, and nervous or functional bowel.

So far, scientific support for the claim that any remedy can treat IBS is fairly lacking. Here's a look at several natural remedies.

Enteric-Coated Peppermint Oil

Enteric-coated peppermint oil is widely used for irritable bowel syndrome. It is purported to reduce the abdominal pain and bloating of irritable bowel syndrome. Peppermint is considered a carminative herb, which means that it is used to eliminate excess gas in the intestines.

Although further research is needed, studies published in 2019 indicate that it may ease symptoms of IBS. Although peppermint oil is available in many forms, it should only be used in enteric-coated capsules otherwise the oil can relax the lower esophageal sphincter and cause heartburn.

Peppermint oil, in excessive doses, may result in nausea, loss of appetite, heart problems, nervous system disorders, and lead to kidney failure and even death.

Peppermint oil should not be taken internally by children or pregnant or nursing women. Peppermint oil may interact with the drug cyclosporine (used to prevent organ transplant rejection and for rheumatoid arthritis and psoriasis), so they should not be combined unless under medical supervision.


Probiotics are living microbial organisms that are naturally present in the digestive tract and vagina. Sometimes referred to as "friendly" bacteria, probiotics are purported to maintain and promote a healthy immune system. including maintaining a healthy balance of probiotic bacteria in the gut.

There are over 400 species of microorganisms in the human digestive tract. The balance between beneficial bacteria and potentially harmful bacteria is important. One theory is that people with irritable bowel syndrome may have an imbalance in their normal intestinal bacteria, with an overgrowth of gas-producing bacteria.

A 2006 study published in the American Journal of Gastroenterology examined the use of three different doses of Bifidobacterium infantis or a placebo in 362 women with irritable bowel syndrome. After four weeks, the B. infantis dose of 1 x 10(8) c.f.u. was found to be more effective than a placebo at reducing abdominal pain, bloating, bowel dysfunction, incomplete evacuation, straining, and gas. There are many different probiotic strains, and some may be more appropriate for irritable bowel syndrome.

The American Gastroenterology Association released a 2020 consensus on the use of probiotics for people with irritable bowel syndrome.  The majority of gastroenterologists agree that patients with irritable bowel syndrome who are symptomatic show benefit when taking probiotics

Partially Hydrolyzed Guar Gum

Partially hydrolyzed guar gum (PHGG) is a water-soluble, non-gelling fiber that may help to reduce constipation and to a lesser extent diarrhea and abdominal pain in people with irritable bowel syndrome. PHGG is purported to promote the growth of beneficial bacteria, lactobacilli, and bifidobacteria in the intestines.

One 2002 study compared PHGG (5 grams per day), wheat bran (30 grams per day), and a placebo in 199 people with irritable bowel syndrome. After 12 weeks, both the PHGG and wheat bran resulted in an improvement in abdominal pain and bowel habits, but the PHGG was better tolerated and preferred.

Food Intolerances

According to some alternative medicine practitioners, food intolerances may play a role in irritable bowel syndrome, possibly by triggering immune responses in the gut leading to low-grade inflammation and an imbalance of intestinal bacteria.

Although not scientifically proven, the most common food intolerances associated with irritable bowel syndrome are dairy, wheat, and gluten

Other Remedies

Stress may play a role in irritable bowel syndrome.

Acupuncture has been explored for irritable bowel syndrome.

Pancreatic enzymes have been suggested for irritable bowel syndrome symptoms that are aggravated by a fatty meal.

Hypnosis, or hypnotherapy, has also been used for irritable bowel syndrome.


Irritable bowel syndrome is a group of symptoms that involves abdominal pain or discomfort along with two of the following three characteristics:

  • Pain or discomfort relieved by defecation
  • Change in the frequency of bowel movements
  • Change in the appearance of stools

Using Natural Remedies

If you're considering using any form of alternative medicine for IBS, make sure to consult your physician first. Self-treating IBS (or any condition) and avoiding or delaying standard care may have serious consequences.
