I have found a near miracle to get relief from the intense itch of Grover's Disease. It is Peppermint essential oil. I mix it with Nivea lotion or Coconut Oil. You can adjust the portion to your own liking. I put about 1 1/2 tablespoonfuls to about 4-5 drops of oil in my hand, mix it up and apply. I get about 10-12 hours of relief from the itch plus it helps with keeping the skin moist and healing. I'm grateful!!!!!
