Ice packs !!! I've had GD for about 5 years now and have tried every topical that gets mentioned on this site. None worked. I did Cilantro smoothies for about 2 years and the disease disappeared for quite a while. It came back in a limited way in that it migrates over my stomach area . It effects one area dies off but just moves to another area. The only thing that quells the itching for me is ice. I put a small ice pack one the area that itches for a couple of minutes and the itching subsides for fairly long periods of time. So far for me, it is the most effective way to deal with the misery. It was something I learned on this site, much the same as the Cilantro smoothies. I take Cilantro oil every day. I am not free of the disease at this point, but at least I have found a way to "manage" it.
