Well, first- congrats on putting your MS into effective remission. I've watched Dr. Wahl's video and it's amazing what she's accomplished. It's great to know that another individual put her ideas to work and achieved similar results. Do you eat as many vegetables each day as she does?
A few years ago I had desperately dry skin. My thighs were so chapped that they burned and itched all the time. This isn't primal but for me what worked was to add in Flaxseed oil to my diet. I began using flaxseed oil instead of olive oil in my salad dressings. Voila, no more dry skin. Just like that. Now my guess is that it was merely a need for more Omega 3's, so odds are you could achieve the same thing primally by adding in cod liver oil, krill oil or a good quality fish oil that's had the impurities removed.
