Colloidal silver is pure, submicroscopic silver particles that are suspended in deionized, ozonated, or distilled water. Colloidal silver is claimed to be effective against 650 different bacteria, viruses, and fungi. It asserts this effectiveness by disabling a pathogen's oxygen metabolizing enzyme while not affecting the enzymes of the human body. In addition, microorganisms do not seem to develop a resistance to colloidal silver.

There appears to be a significant amount of conflicting information regarding the effectiveness and safety of using silver products. An ideal approach would be to gather information on colloidal silver from various sources and discuss with your naturopath or other health practitioner as to the appropriateness of this substance for your needs.
