Re: Ionic Silver
A true colloid is the best way to get silver. Some of the products out there settle out. A true colloid doesn't as all the particles are small enough to stay suspended in water by brownian action. If you shine a light beam through a colloidal suspension, you can see the beam, just like a sun ray in a dusty room, only much finer resolution.
The trick to making a true colloidal silver is low voltage and controlled current. I invented a device to do that. Makes 5 - 20 ppm, your choice. The colloid won't settle out. Samples here that are years old are still in spec.
At today's prices there's about 4 cents in a gallon of 10 ppm. You lose a little in the electrode cleaning, so it costs about 10 cents plus the cost of the distilled water to make a gallon.
The guy that turned blue made his by connecting several 9 volt batteries to silver electrodes. That would run away and make a fairly heavy concentration 100's of ppm of small, but mostly not colloidal particles. He stirred the mud and drank a pint a day. No durned wonder he turned blue.
European royalty was known as blue-bloods. Their complexion tended toward a bluish tinge because they always ate off silver plates with silver utensils. Acids in their food would take a bit of that silver into their bodies. They also were noted for their good health. The silver probably protected them from common microbes.
It works. It's cheap. Any side effects are cosmetic. (like turning blue if you get crazy with it.) I can't make any definitive claims without getting into legal trouble.
