Hi,
I think tonight I have finally solved the mystery of the red,itchy plaques which have plagued our 13 year old daughter for over a year now. I did a lot of Google image searching, and came up with Psoriasis again and again. Then I saw your post and the replies. I can tell you that since our daughter has been taking Colloidal Silver orally and spraying it on the places where the plaques are, they seem to be clearing up, although very slowly. Now that I've seen people mention Beck's other things, the mag pulser, blood electrifier,and water ozonator, we will definitely add it to the Colloidal Silver therapy.
We will also try the oil of oregano.
I hope these things help resolve your son's psoriasis.
