Here is an amazing extreme almost dying psoriasis cure story by Vanja, an expert on Curezone.com. An excellent example of stress induced disease. Your unconscious mind can induce any pain or disease possible to keep you from dealing with what is tearing you up.
I would note that the psoriasis of this man was cured by removing stress and doing the rest of the cure protocol of Vanja. So please do not be misled that you can just de-stress and that one item will cure you.
