is a liquid suspension of microscopic particles of silver. A colloid is
technically defined as particles which remain suspended without forming a
dissolved solution. Colloidal silver with concentrations of 30 parts per
million (ppm) or less are typically manufactured using an electrolysis
process, whereas colloidal silver with higher concentrations of 50 ppm or
more are usually silver compounds that have been bound with a protein.
Colloidal silver is
currently marketed for internal and external use as an alternative medical
remedy. Studies have demonstrated the anti-bacterial effect of electrically
generated silver ions. Excessive ingestion of colloidal silver can result in argyria, a cosmetic condition in which the skin irreversibly turns blue or
anti-bacterial powers have been tested and proven scientifically even though
its power as a bactericide has been known for centuries. The ancient
Phoenicians, for example, knew that water, wine or vinegar kept in silver
vessels stayed fresh during long sea voyages.
Silver interrupts a
bacteria cellís ability to form chemical bonds essential to its survival.
These bonds produce the cellís physical structure so bacteria in the
presence of silver literally falls apart. Cells in humans and other animals
have thick walls and are not disturbed by silver. Therefore, silver prevents
bacteria growth but is harmless to humans.
One of the most
important uses of silver as a biocide is in hospitals and other health care
facilities because they grapple with MRSA (Methicillin-resistant
Staphylococcus aureus), a type of life-threatening Staph germ. MRSA is
resistant to almost all chemical antibiotics, so many hospitals are
employing silver-imbedded equipment including surgical tools, catheters,
needles, stethoscopes, furniture, door handles and even paper files.
too little data involving cancer and colloidal silver to definitively draw
any conclusions on efficacy of any treatment. However, many personal
experiences exist that show at least a beneficial effect of use, even when
normal allopathic treatment is administered.
