Argyrol

Argyrol is the trade name for an antiseptic consisting of compounded solutions at varying strengths of mild silver protein. Agyrol is synonymous with its chemical mild silver protein, manufactured in the chemical industry to pharmaceutical grade only, using denatured pharmaceutical-grade protein for ophthalmic application and elemental silver to produce the silver protein molecule. While employed with Mulford & Co. (which became Merck & Co.), the American physician Dr. Albert Coombs Barnes recruited chemist Dr. Herman Hille in Germany. They returned to the United States and left Mulford together to launch Argyrol, developed and commercialized by Barnes as Prevention Technology for use on mucous membranes to resolve local infections in mucous-membrane-lined organs, most widely publicized for its value to resolve gonorrhea infections and to prevent gonorrheal blindness and other pathogenic infections to the eyes of newborn infants.
