Argentyn 23 (Colloidal Silver)

Throughout history, silver has been used to improve human health.

Silver vessels were used by ancient Greeks, Romans, Egyptians and Phoenician to preserve drinking water.¹ The father of medicine, Hippocrates, first described silver’s antimicrobial benefits, writing about its healing and anti-disease properties.² In the Middle Ages, the wealthy benefited from silver eating utensils, giving rise to the phrase “born with a silver spoon in your mouth.”

Silver’s antimicrobial and wound healing properties were applied to battlefield medicine in the 1800s. Fine silver wires used for sutures contributed to faster healing, and silver nitrate was used to treat wound and skin ulcers. Silver was also used to treat syphilis during the Civil War, and in the 1880s, silver nitrate began to be used to prevent infections in the eyes of newborns.³

Current uses of silver coating include invasive medical devices such as catheters and endotracheal tubing, preventing bacterial colonization and biofilm formation.^4-6  Silver-based water purification systems are installed and used on the international space station.⁷

Silver occurs naturally in many places, and it is found in many foods, such as wheat, fish,⁸ mushrooms⁹ and mammalian milk.¹⁰ A study in the United Kingdom concluded that the average adult’s daily diet includes 27 micrograms of silver.¹¹ Silver is also naturally present in river waters in some areas.¹²

The health benefits of silver have been widely studied for thousands of years, and the effectiveness of its contemporary use for immune support and topical healing applications has been significantly substantiated.  While the Ancients did not know the chemical and biological mechanisms of how silver metal preserved their drinking water, the modern peer-reviewed literature has elucidated them.  We now know, it is the outermost silver atoms of the silver nanoparticle that undergo surface oxidation and, when mixed into a pure water medium, subsequently release bio-active silver ions into the water, which provides the health benefits.
