This is a very good suggestion. Yes digestion or lack of proper digestion is the root of all body evils. Unfortunately Psoarisis is not one of them. It is purely a genetic mutation of the immune system. I have had 58 years worth out of my 58 years of age. It is not a disease but rather a genetic disorder. The immune system sends signals because of this genetic mutation, to the skin and believes that it needs to defend itself against itself ..hence the build up of the plaques. Once it tries to get rid of itself(and all normal people get rid of dead skin cells everyday), people with this disorder can't get the correct signals from the genes to react in proper sequence. Yes, many things in our world trigger responses from this gene, good triggers and bad triggers. My condition covers about 90% of my body. From time to time I make progress and sometimes not so much. There is no cure only treatments. Sadly to say. During my research I have used just about every OTC and prescription you could buy. Still have it!! oh well, I am researching into more naturals products and am tired of the same ole same ole manmade stuff that doesn't work.
