I am using the sprayed silver to fend off germs and it works. I'd been sick constantly for thirty years and it just kept getting worse. There was past trauma that kept me from ever being well, and once I realized what, that was, and went over some ways of setting bounderys in the future, no more problem. But germs did try to get me after, said realization. More than once. And, except for my candida infection // overgrowth as said before, I'd been as well as anyone. Which should not be possible. But between the silver and elderberry I'm doing fine.
