Ed,
Not meaning to open up a can of worms here, but I just noticed that the bottle in the picture you provided includes the word "homeopathic" on it. If it truly is homeopathic (and the word isn't just being used for marketing purposes), by definition it will not contain a single molecule of silver in it. The whole concept behind homeopathy is extreme dilution on the order of 1 part in 1,000,000,000,000,000,000,000 and the belief that the water molecules somehow retain a "memory" of the original silver that was present before dilution.
If the solution helped your infection, that's fine. And, as I said, some manufacturers actually do include real active ingredients in their products and just use the word "homeopathy" as a marketing gimmick (Zicam cold relief, for example, actually contains a significant amount of zinc in it despite the homeopathic label). And there's also things like the placebo effect and the fact that minor conditions often clear up on their own regardless of the treatment (which, I know, nobody wants to hear or believe when they become convinced that a particular treatment has "worked" in their case). And yes, I have researched this extensively and can provide some references if you'd like.
My point is simply that it's probably not a good idea to promote a homeopathic remedy as evidence of the healing power of silver since it very likely contains no silver in it whatsoever.
