Particle size must be nano and silver must be pure, not a silver salt. No silver halide, no silver chloride, no silver nitrate. Then no problem.
This is purely a scare tactic by the medical and pharma industry to scare people away from using a safe, effective, inexpensive remedy against almost EVERYTHING that you can make at home.
Don't post this bullshit again.
I know what I'm talking about from personal research and over personal experience of two people 20 years of using home made nano-particle-size pure colloidal silver orally, daily, and externally as needed for cuts & scrapes.
No problem. No illness. Cuts and scrapes heal twice as fast. Also heals animals.
Shame on you for distributing pharma's message, to anons' detriment.
