I have ReA aka Reiter's Syndrome. I used four gallons of WaterOz Colloidal Gold several years ago. It helped a lot.
My research indicated that the mechanism of action of Gold Salts was after the body separated the gold out of the salt. It turns out to be the same mechanism as Colloidal Gold . The main difference is the shape of the particle from Gold Salts and Colloidal Gold .
Their is also the facts that Gold Salts are very toxic, expensive, and by prescription. Colloidal Gold on the other hand is nontoxic, Relatively inexpensive, and over the counter.
