I discovered the beneficial effects of colloidal silver years ago and will never be without it in my medicine cabinet. I've used it for infections, 'flu, colds, and as a preventative when I think I've been exposed to some contaminant.
Last year I kept contracting the flu and spent most of the winter in bed. This year it started to come back. I lived alone with no real friends in Reno so I read up and selected Colloidal Silver as the best bet. I went and picked up some high quality Colloidal Silver. Within a few hours the flu symptoms were gone. I tend to be minimal with medicine so I only used the silver when I felt bad. No flu yet this season.
I used a teaspoon several times a day of a top rated brand. I also could not afford to keep buying it so I bought 2 Canadian silver dollars and made my own machine. I am an electronics tech and did well in my college chemistry so it seemed obvious how to build a device that would yield a higher percentage of true colloidal over an ionic solution. You MUST use distilled water and shiny clean electrodes. I heated my water and drove off the dissolved gasses. I used a 30V square wave at about 50kHz to theoretically dislodge microscopic particals of silver into the solution. After about 4-6 hours the electrodes start showing some corrosion and have used that as my finish point. It has worked as well as the store bought solution at a fraction of the cost. I have been giving out bottles to people I'm starting to know and to date, none of them have gotten sick from the flu this year.
