Colloidal Silver is a fairly reactive.

Remember that silver was once used for old black and white photographs.

Exposure to an oxidizing agent such as peroxide will probably oxidize a lot of the suspended silver to be silver oxide, and the color change that you see to brown is probably due to the silver having oxidized.

By putting peroxide into the CS, you are very probably deactivating it by changing its chemical properties even before it gets a chance to enter your body.

Remember that after a metal oxidizes, lots of its properties go away. For example, the shininess of polished iron or polished silver gets diminshed / eliminated when tarnished or rusted. Usually a shiny metal indicates a lot of nice electrons easily able to move around. The shine is not there in rust. Rust can form on steel too. Even on poor grades (crappy) of stainless steel.

I suspect that rust is not a good conductor. Copper when it oxidizes turns green, and this green stuff is probably not a good conductor either.

Many other chemical properties probably change after a material has oxidized.

Bye.
