Blue Man "Papa Smurf" essentially tried to turn blue. He made his own silver that was not high quality. And he was drinking like a gallon a day…
Personally, I have had amazing results getting over sickness, killing infections, healing pussy infected external wound over night with Colonial Silver!
Do your own research, but it is powerful stuff.
I even used it in my fish tank to heal fish and eliminate a kill of cyanobacteria.
