Colloidal silver kills over 650 pathogenic organisms including bacteria, yeast, mold, fungi, prototzoa, parasites, and virus by destroying the enzymes responsible for cellular respiration, thus depriving them of the ability to breathe. There is no chance that survivors can develop resistance or immunity to silver. Regular ingestion of small quantities of colloidal silver can act as a second immune system by assisting the body in the war against invading micro-organisms. Unlike antibiotic drugs, colloidal silver is not toxic, and will not suppress the immune system.
