Thanks for finding that. Someone posted that he said he is an "elderly, long time Silver List gentleman." The "Silver List" is a forum on Colloidal Silver which Marlys belongs to. Then she posted what he said. He thought Jim's warning wasn't strong enough, and so he said it could strip arterial plaque away before the artery could heal.
That is what scared me about my dad, so I just have him still on one drop and taking C. The guy said he was having heart trouble. I know from my mom, she always meant her chest and heart felt funny. And he did say he already had heart trouble. I think it would be good for these people to go extra slow. Even this guy was still going to use it. He said it cleared a sinus infection he had that he didn't realize was as big as it was. So, it would be a shame for them to not get the benefits like everyone else can.
I guess Scott has been around it for long enough to realize a lot of this. Slower works without a doubt. So, if there is any question, just keep the amount low.
