Take a guess on how many incidences of this have happened over the years?
I am going to give you a number, will not back it up, do your own research.
And if I am correct, that video is of a doctor that takes colloidal silver, I could be wrong their.
Anyway, the bluing of the skin does not actually cause any health problems.
Appx 10 incidences over the last 10 years, wow, I wonder how many deaths could be attributed to other drugs.
Colloidal silver is absolutely safe if you get the correct brands and do not go to these folksy places on the net and get their snake oil.
I swear half of those places are set up by big pharma to cause these problems.
I know, a little paranoid, but a little paranoia goes a far way in today's world.
