Hey J look into adding some EFAs(essential fatty acids) to your diet after you're done with the MC. From everything I've read they're excellent for psoriasis. I don't have Psoriasis but I do 2 tblsp of Flax Oil everyday along with 1 tblsp of coconut oil
The addition of EFAs is not just for Psoriasis but it is one of the most common defficencies in the SAD because of all the saturated and rancid fats consumed and in vegetarians diets by omission. The 2 links below are excellent sources of info on EFAs.
