I saw one mint called Yerba Buena for sale at a grocery store. I'm thinking I might try it. That one is from Mexico...not sure if it's at all cold-hardy, however. Then I heard of an herbal tea for digestive problems...which I've got plenty of the digestive problems. It's called CCF for Cumin, Coriander and Fennel seeds. Found instructions on this website.
