Home Remedies for Menstrual Cramps

I've been using peppermint oil on my lower abdomen over my uterus and it helps tremendously with menstrual cramps. I don't have sensitive skin so I don't dilute it but if you do have sensitive skin you might want to dilute it with a carrier oil. I've had terrible cramps since my teen years because of endometriosis and this is one of the few remedies that gives me relief.
