I just caught this on Loren Cordain and his Paleolithic diet newsletter:

"Rosacea Treatment Program - We are looking for 10 people with Rosacea to try a special diet and supplement program that we believe may be successful in treating the disease. This is not an official study and we will not be paying for any of the food or supplements, but we will give guidance on both. We request that participants continue the program for 8 weeks. If you are interested, please email support@ThePaleoDiet.com, and we will send you an application."
