Good for you for attempting a holistic approach!! Have you tried probiotics at all? Don't know how much affect they would have on psoriasis, but they help to get your body processing all the food we eat naturally, and avoiding those inflammatory triggers may assist a little? I'm a huge holistic fan - so many of our human ailments begin in our gut!! :) http://www.huffingtonpost.com/2013/03/21/inflammatory-foods-worst-inflammation_n_2838643.html
