In general, it soothes the lining of the digestive tract. Buy pure peppermint tea, brew it in a covered container to retain the volatile components, and drink it hot or iced. Chamomile is also excellent for heartburn and indigestion, and will not aggravate esophageal reflux. You can buy it in tea bags in a supermarket - steep in hot water in a covered container for 10 minutes, and then enjoy. I also feel strongly that people with stomach problems should not rely solely on remedies.
Smoking is another cause of stomach distress.
I'd encourage you to make some dietary experiments to see if you can reduce symptoms and thereby eliminate the problem. Try eating smaller amounts more frequently. And work on generally reducing stress in your life. Digest in the Boards. Inc. All rights reserved.
