Indigestion: Peppermint oil is very helpful as an aid for digestion. People often put a few drops of peppermint oil in a glass of water and drink it after their meal for its beneficial digestive properties. It is carminative and therefore helps in removing excess gas. Peppermint oil is also a good tonic for those who have a low appetite, and it helps treating motion sickness, nausea and upset stomachs. Preliminary research has proved that peppermint oil, when combined with caraway oil can be used for treating heartburn.
Peppermint oil can relax the smooth muscles of the GI tract, which is why it is so commonly a component of “over-the-counter” medications. A number of studies have also shown it to be a great reliever of Irritable Bowel Syndrome (IBS), which affects millions of people every year and is characterized by abdominal pain or discomfort without any other diagnosed disease. Further research still needs to be done on the exact mechanism by which this occurs, but numerous studies have validated these effects.
