You are so knowledgable about silver that I have a question for you. I purchased silver from Source Naturals and took a total of two teaspoons. This silver doesn't seem to be clear in color. It seems to have a yellowish cast to it. Anyways, now I have developed a huge oozing itchy sore right where the crack of the butt starts. Sorry about being so graphic except I was wondering if the silver could be causing this. This is not the first time I have gotten this and unfortunately I haven't paid attention to whether I got it any other time while using colloidal silver. Any thoughts about whether the silver could be causing this and if so does that mean I am allergic to colloidal silver???? Thanks for the input.
