<<Disclaimer: Verify this information before applying it to your situation.>> I received two answers to my Cortizone 10 question. They are: 1.) "Sorry, I don't actually know. However, I do use them, and never had any reaction. I have Dermatitis Herpetiformis." 2.) "...you aren't planning to eat it are you? Otherwise it shouldn't be a problem unless you put it on your lips" ***Of note, we were under the impression that gluten to the skin was not a good idea either, thus my question. Since diagnosis, my mom has used GF shampoo, soap, etc.. So with the second answer, one can use your own judgment. Susan
