/sci/ - Science & Math

So I just visited my grandfather today. Ya'know, the kind that now sells oil at home, trusts in commercial vitamins & herbs, hoardes expired rations, and believes the earth is 6000 years old. Oh boy.

But what intrigued me was 'Colloidal Silver', a alternative medicine that sounds like bullshit. So is this stuff a miracle? Merely another bit of false science meant to die in the past? I want the facts.

Newfag here btw, sorry if this is dumb.
