Peppermint Oil for Upset Stomach

Don’t you love it when science solves the mystery of a time-honored home remedy? It’s happened again, and to one of our favorite digestion soothers: peppermint. Turns out that this ancient herbal tummy tamer does its thing by switching off pain-sensing nerve fibers in your digestive system. Who knew?

That helps explain why pouring yourself a steaming mug of peppermint tea for an upset stomach, or popping an enteric-coated peppermint oil capsule to ease irritable bowel syndrome (IBS), really works. 

We’ve known for a while that mint relaxes smooth muscles in your GI tract, which can tone down IBS cramps. That’s super-useful if you’re among the one in five people with this uncomfortable problem. Now we also know it can mute hypersensitive nerves, which can trigger internal distress after a spicy meal, too much coffee, a glass of wine, or during a bout of flu. 

Peppermint tea may be all it takes to soothe a queasy stomach or settle one that’s gassy and bloated. But it may take a stronger dose to ease IBS. That’s where peppermint oil capsules come in. To give them a try, stick with 0.2 to 0.4 mL of oil three times daily and use only enteric-coated versions to avoid heartburn. Otherwise, the muscle-relaxing oil could relax a valve at the top of your stomach, allowing acid to backwash into your esophagus. That hurts. Tip if you’re heartburn-prone: Skip mint chewing gum for the same reason.
