I know that pepermint is supposed to help, I drink tea with dried leaves in it on a regular basis. The other thing that has been working for me is a product called Iberogast. It's completely Herbal, 9 items all together I think. Pepermint is one of them. I take it three times a day, usually with meals and it's made a huge difference for me. I'm also taking a probiotic (Florastor, made by the same company!) because I have a lot of diarreah. I would suggest trying either product if you want to go the natural route.
