Well I addressed Boron. While it's not a heavy metal, it is very toxic. Apparently it stops arthritis, but at what a cost.
It kills the parasites and their infections (like it kills ants) when it settles in the joints. And so the 'arthritis' stops and the ligaments/fascia can regrow. But it's more like soaking your feet in radioactive water to kill a foot fungus. The cure is worse than the disease, by far.
I'm learning that boron is more toxic than lead and cadmium.
And on and on about the zapper is 'not really helping', maybe even hurting. Good grief, from all the outright lies and blatant misinformation and every single one of the employees dressing up as someone else or maybe two, they just keep pounding the same garbage over and over doing all they can to keep people from using it. *sigh* It's wearying, for sure. But with the boss gal gone, it ought to be getting less. *fingers crossed*
