Depends on how many ppm your solution is. If I take a 500ppm in water, I use 1/4 teaspoon in a small amount of water. If it’s my home made 20ppm, it depends on whether I’m just taking a maintenance dose—say an ounce every few days—or if I’ve got an infection. If you take 4 oz of 20 ppm, you’re hitting the infection pretty hard. Just be aware that multiple daily doses will wipe out your gut flora unless you eat yogurt between doses. I did that once. Tells you how powerful an antibiotic it is. But they’re easily restored with cultured milk products with living cultures. A nebulizer is a real advantage against respiratory bugs. The silver gets where it needs to go undiluted by body fluids. But I think it’s important to consider that over time the particulates, though they are extremely small, may build up in the lungs? It’s a shame we have to figure this out, but since the fda won’t perform the studies and standardize treatments, telling us instead that silver is dangerous and ineffective, well, y’on y’own. (Back in the ‘30s they did do a study and found that silver cured more than 600 illnesses—but that was a different FDA. I can’t find that report anymore—go figger.) But it’s certainly effective. And every drug on the market is dangerous. I started using silver 20 years ago. I’ve died only a couple of times since then! 😵
