Colloidal Silver is a tasteless, odorless, non-toxic, pure, natural substance consisting of sub-microscopic clusters of silver particles, suspended by a tiny electric charge placed on each particle, within a suitable liquid. The molecule's size is .00001 microns or 1.26 angstroms in diameter (very small).   Colloidal Silver is an antibiotic, antiviral and antifungal. It kills a broad range of disease microbes (usually in 3-4 minutes) including E. coli, Staphylococcus aureus, Streptococcus pneumonia, Salmonella arizona, B. tuberculosis, anthrax, and more.
