Two naturopathic doctors, Michael Murray and Joseph Pizzorno, explain how natural therapies are used to treat common health conditions. In "The Encyclopedia of Natural Medicine," they provide tips for living a healthy lifestyle and using supplements and botanical medicines. The doctors give examples of how holistic medicine can be effective, using information from scientific studies.
Mint has been used for hundreds of years as a health remedy. Peppermint oil might help with irritable bowel syndrome -- a long-term condition that can cause cramps, bloating, gas, diarrhea, and constipation -- and it may be good for headaches as well. More studies are needed to see how much it helps and why. People use the leaf for other conditions, too, but there’s very little evidence it helps with any of them.
