I have used colloidal silver for 10+ years 2 ounces a day no problem
I have used colloidal silver for 10+ years 2 ounces a day internally with out any problems. I still look normal.
The famous smurf was making his own with salt - THAT IS NOT COLLOIDAL SILVER - that is called a silver compound this creates larger particles that will become stuck inside cells and will grow larger with continued use, when exposed to sun lite it will turn blue-gray color. He drank about a gallon a day. One does not need that much even if you were expose to some serious viral infection. Best dosing is little at a time, do not mix this with anything as you will have silver compound not silver colloids. Take on empty stomach only eat 10-15 minutes later - this way you will not mix food salts with the silver. To get silver into blood stream you can use it under the tang for 10-15 minutes 4-5 times a day, then spit out or swallow.
To make silver colloids one uses DC or AC current and the purest distilled water only, nothing else. 3 batteries in series with pure silver wires or coins (.9999 purity or 99.99% or better), or leafs (do not use jewelry silver ever, it is not pure silver).
Store in dark location at room temperature, never refrigerate or freeze, never expose to sunlight, never use metals to dose. Keep out of sunlight.
