Quack remedy colloidal silver is also a good source of: argyria. Don't turn out like this guy.
You must be using it as a preventative. How do you use it, and what brand of colloidal silver do you use? I've never used it, but have about decided to get some to have on hand.
Colloidal silver does not affect viruses. It will neither prevent nor treat flu.
It kills bacteria but is much more effective for external use than internal, and one needs to be careful about internal use. It is not a cure all. Nothing is, actually.
I’ve made CS and used it for some things and it’s a useful thing to have around but does nothing against viruses.
PS the best preventive that I know of is elderberry syrup. Elderberry syrup or tincture, when made properly (ie not over heating the elderberries) prevents the flu viruses from replicating in cells, which they have to do to give you the flu. It weakens the viruses, and also strengthens the cells walls so the viruses can’t get in.
Take 1 to 2 teaspoons a day as prevention, and even if you do get flu, it won’t be as severe, and as soon as you get ANY symptoms at all or think you’ve been around people with flu, start taking up to 3 or 5 Tablespoons a day.
I make my own syrup and tincture and prefer syrup as I can’t handle 1 T of alcohol and plus grain alcohol is more expensive than honey or sugar. I use 50/50 well water and grain alcohol for the tincture.
