What would you suggest for someone with a severe case of psoriasis? My teenage son is having a hard time with this disease. I know diet has a huge role in all of this but I am having a very difficult time getting him to cooperate and change his typical american diet. I am desperate to get this condition under control especially with all the scare about staph infections. Currently I have him taking colloidal silver to help with any virus, bacteria, etc. Any suggestions that you might have would be very appreciated. Thanks
