I have a neighbor that had psoriasis on her lower arm and I make colloidal silver she asked me for some because it was so good on rashes.
She applied it by gently rubbing it in until it was nearly dry and also in the evenings she soaked clothes with it and applied it for several hours while watching tv. It was gone in 3 weeks. Amazing. That was two years ago and it has never come back.
