Well if you drink several cups of peppermint, it can help with mild pain. Especially headaches. I prefer the taste of peppermint personally. But spearmint nauseates me and I haven't heard as much about it's medicinal properties. Though I'm not saying that means it doesn't have as many..it's just I don't hear of it's benefits as much. I think mints are underestimated and there ought to be more studies done on them. I have tried applemint, but a while back, and honestly can't remember much, other than liking it (wasn't as big on tea then though I enjoyed it immensely). Have you heard anything on chocolate-mint? I was actually curious about that.
