What Are the Benefits of Enteric-Coated Peppermint Oil?

Known for its fresh, naturally sweet flavor, peppermint is a commonly grown herb that is actually a cross between water mint and spearmint. The leaves, either fresh or dried, are often used to brew an invigorating tea, but according to the National Center for Complementary and Alternative Medicine, peppermint oil has long been used to ease nausea, digestive problems and headaches. More recently, peppermint oil, taken in liquid form, capsules or enteric-coated tablets, has become a popular supplement used to ease the symptoms of irritable bowel syndrome (IBS).

Benefits

• The word enteric relates to the small intestine. The purpose of enteric coating, seen as a thin, shiny layer on many pharmaceutical and over-the-counter medications, is to prevent a medication from dissolving before it gets to the small intestine. This is beneficial because some otherwise helpful ingredients can have an unpleasant taste or reflux. Using enteric coated peppermint oil will guard against any unwanted side effects from premature dispersal of the oil into the stomach.

Effects

• According to information posted by the University of Maryland Medical Center, peppermint oil may possess antibacterial and antiviral properties. When taken in the proper dosage, enteric-coated peppermint oil increases the flow of bile in the stomach and relaxes the stomach muscles, therefore easing symptoms of indigestion, flatulence and bloating. Enteric-coated peppermint oil may also make cold sufferers feel better as it breaks up phlegm and soothes a sore throat.

Expert Insight

• While the popularity of enteric-coated peppermint oil for treatment of irritable bowel syndrome has recently grown, experts at the University of Maryland report that while some studies suggest enteric-coated peppermint may alleviate the pain, bloating, gas and diarrhea experienced by those with IBS, "other studies have shown no effect."

Warning

• As is true for many supplements, enteric-coated peppermint oil can interact with prescription or over-the-counter medications. Coated or non-coated peppermint oil may worsen heartburn for sufferers of gastroesophageal reflux and may also worsen some types of gallstones. Peppermint oil may be toxic in large doses. For all of these reasons, consult your health care professional before using peppermint oil in any form.

Dosage

• Adults taking enteric-coated peppermint oil to alleviate symptoms of irritable bowel syndrome should take one or two capsules or 0.2 ml, two or three times per day.
