People think that they can continually take Colloidal Silver to fight some microbial condition in their body but it helps just a little since whatever they take becomes highly diluted in the body. (The exception to this is when there's an infection in the stomach or intestines.) You are mostly composed of water (65%). Take a tablespoon of 5ppm C.S. and mix it with 10 gallons of water (body amount) and the 5ppm (which is necessary to kill microbes) becomes 5/2560=.002ppm Colloidal Silver . Do you think .002ppm C.S. will do you any good? A Microbe Electrifier is more than up to the job already and does no harm. Maybe you think that drinking a cup of C.S. daily is OK. 8 ounces of 5ppm C.S. is 16 times the RDA for silver. Doing this for any more than a week causes a dangerous buildup of this metal in your body to toxic levels. I had a client who got overdosed with silver (40x times normal blood level) from taking 2 tablespoons nightly for 4-5 months which is why I recommend therapeutic dosages only for a few weeks.
