I have a DH rash on my chest. Have had celiac 6 years and this is the first time with this reaction. I recently read about the healing properties of coconut oil. Last night the itching and burning was driving me nuts and I couldn't sleep. I had an old, barely used jar of coconut oil in the back of my fridge.It was hard and cold. I scraped some off with my fingernail and applied it to the rash. Relief was immediate. The burning stopped, the itch was still there but not too much. I have to reapply when it starts back up but so far so good. I have noticed that my skin is peeling a little like a sunburn. I used Organic Unrefined Expreller Pressed Virgin Coconut Oil. How long will this last?
