It matters to me.
Some try to utilize silver's properties in supplements and liquid
forms, known as colloidal silver. Keith Moeller is the managing
director of American Biotech Labs, which sells a supplement that uses
a relatively sparse 10 parts of silver per million. He cites studies
that claim the company's products can boost immune systems and fight
malaria, salmonella, E. coli, bird flu and other ailments. Company
president Bill Moeller testified to Congress in 2005 about the
products' medical potential.
Studies which are listed in pubmed?

Silver in health care: antimicrobial effects and safety in use.

Silver has a long and intriguing history as an antibiotic in human
health care. It has been developed for use in water purification,
wound care, bone prostheses, reconstructive orthopaedic surgery,
cardiac devices, catheters and surgical appliances. Advancing
biotechnology has enabled incorporation of ionizable silver into
fabrics for clinical use to reduce the risk of nosocomial infections
and for personal hygiene. The antimicrobial action of silver or silver
compounds is proportional to the bioactive silver ion (Ag(+)) released
and its availability to interact with bacterial or fungal cell
membranes. Silver metal and inorganic silver compounds ionize in the
presence of water, body fluids or tissue exudates. The silver ion is
biologically active and readily interacts with proteins, amino acid
residues, free anions and receptors on mammalian and eukaryotic cell
membranes. Bacterial (and probably fungal) sensitivity to silver is
genetically determined and relates to the levels of intracellular
silver uptake and its ability to interact and irreversibly denature
key enzyme systems. Silver exhibits low toxicity in the human body,
and minimal risk is expected due to clinical exposure by inhalation,
ingestion, dermal application or through the urological or
haematogenous route. Chronic ingestion or inhalation of silver
preparations (especially colloidal silver) can lead to deposition of
silver metal/silver sulphide particles in the skin (argyria), eye
(argyrosis) and other organs. These are not life-threatening
conditions but cosmetically undesirable. Silver is absorbed into the
human body and enters the systemic circulation as a protein complex to
be eliminated by the liver and kidneys. Silver metabolism is modulated
by induction and binding to metallothioneins. This complex mitigates
the cellular toxicity of silver and contributes to tissue repair.
Silver allergy is a known contra-indication for using silver in
medical devices or antibiotic textiles.
