Colloidal silver spray is a liquid solution of water and small silver particles used as an antibacterial topical solution to treat skin infections. However, it can cause argyria, a condition in which the skin turns blue or gray, and interfere with the body’s ability to absorb prescription drugs. Silver was historically used for medical remedies and is still used to disinfect swimming pool water and purify water for astronauts.
Colloidal silver spray is a liquid solution of water and very small suspended silver particles. The spray is touted for its antibacterial properties and is often claimed as an alternative medicine method of boosting the immune system. In spray form, colloidal silver is used as an antibacterial topical solution to treat or prevent fungal infections of the skin. Although there is no consistent scientific evidence to support the health benefits of colloidal silver spray, it is true that silver does have germ-killing properties. In addition to its use as an antibacterial, this spray is sometimes used as a body deodorant, to treat ringworm, and as a shoe deodorant to kill microbes that cause foot odor.
One of the dangers of using colloidal silver spray is argyria, an irreversible condition in which the skin turns blue or gray. The silver in colloidal silver spray is absorbed into the skin and accumulates over time. When exposed to sunlight, silver in the skin darkens, causing a bluish tint. Colloidal silver spray can also interfere with the body’s ability to absorb prescription drugs and can cause kidney damage, digestive tract problems, and neurological problems in sensitive individuals.
Silver was used historically by the Greeks and Romans and throughout history. Vessels made of silver held water and other liquids to maintain coolness. Pioneers in 18th century America dropped silver coins into wooden barrels to prevent bacteria and algae from contaminating the water or milk. Australian outback settlers placed pieces of silver in their cisterns. In the 19th and 20th centuries, doctors placed silver nitrate in the eyes of newborns to prevent blindness, and silver was an important ingredient in wound dressings, nose drops, and tonics, and was used as a mineral supplement.
Until antibiotics were developed in the 1950s, silver was widely used for medical remedies. Today, silver is a component to disinfect swimming pool water and to purify water for astronauts in space. As a colloidal base used externally, silver is non-toxic and works as a topical antibacterial spray.
