My first foray into the advanced technology frontier began with Dr Clark’s zapper. I paid about 15 bucks for this little device that had 2 frequencies and it has paid for itself a thousand times over. For virus or yeast, it has worked wonderfully. Cant say for sure on bacteria, though Dr Clark says it will kill them. Anyway, until recently, I was using it whenever I needed to. It’s important I think to pay strict attention to her advice about water intake. You can tell it’s working if you get a sudden increase in energy after zapping.   visit the page
