I always hear things about Peppermint this and Peppermint that and I'm wondering if there is really a big difference between the properties of the different types of mint. I have some mint growing in my backyard but hell if I know what variety it is. I also have pond mint that looks different than the regular found it growing just outside my fence and stole it from the bugs mint. Are any and all of these varieties going to be nice? Specifically I'm making a vinegar rinse at the moment with rosemary, sage and some of this mint that I have. I figure the worst it can do is make my hair fall out, leach into my brain, kill me and bring about the zombie apocalypse. And really, would that be so bad?
