Silver has been
used for centuries to prevent and treat a variety of diseases,
most notably infections. It has been well documented that
silver was used in ancient Greece and Rome as a disinfectant
for water and other liquid storage. Silver coins were placed
in the jars of liquid to maintain sterility. The American
Settlers (1800s) routinely place a silver dollar in barrels
of liquids to avoid spoilage and more recently NASA has used
silver to maintain water purity on the space shuttle. The free
silver ion or radicals are known to be the active agents
of anti-microbial silvers. Of interest is its extremely potent
antibacterial properties as only 1 part per 100 million
of elemental silver is effective in a solution. Silver ion
kills micro-organisms instantly by blocking the respiratory
enzyme system (energy production) while having no negative
effect on human cells.
In 1834 the German
obstetrician F. Crede used a 1% silver nitrate solution as eye
drops in newborns, eliminating blindness caused by post partum
eye infections. Numerous studies in the early 1900s
correlated low plasma silver levels with infections,
suggesting silver to be an essential micromineral
requiring replacement. Of significant importance is that no
known BACTERIAL RESISTANCE has developed to the silver ion as
opposed to current antibiotics. Charged silver solutions
(electro-colloidal) were approved in the 1920s by the FDA
for use as an antibacterial agent.
In addition to its
recognized antibacterial properties silver solutions,
especially (electro-colloidal elemental silver) were reported
to improve the healing of "indolent wounds" and in
the regeneration of damaged tissue unrelated to its effects on
infection. The description of decreased rubor in wounds
indicates an anti-inflammatory property of silver.
Silver is
completely non-toxic to local tissues and painless upon
application. This response must be distinguished from the
response of silver salts, many of which are caustic to tissues
especially silver nitrate due to the potent oxidizing or cell
damaging effects of nitrate or nitrite. Virtually all of the
reports on the use of the pure elemental silver to control
infection or to increase healing occurred prior to the
1940s after which antibiotics became prevalent, decreasing
the use of silver (except in burns). With the recent
introduction of a pure silver delivery system for use in burns
and wounds, new data is being obtained which verifies these
historical concepts. (To be presented)
Silver was
commonly worn in the Greco-Roman period because of its
perceived qualities of "maintaining health".
