One thing I recently came across that I did not know is it was used under the trade name Argyrol as a preventative measure against VD/STIs.
https://en.wikipedia.org/wiki/Argyrol
It might just be useful again due to the emergence of antibiotic resistant strains of certain things that are considered "nuisance" infections.By World War II, Argyrol post-exposure male hygiene was mandatory in the U.S. and Allied Military VD Prevention Technology for sexual hygiene. With the advent of antibiotics, prevention was outdistanced by the promise of cure by simple injection. Thereafter, Argyrol Anti-Infective became infrequently prescribed because Argyrol's 10% Stabilized Solution was available as an over-the-counter pharmaceutical, while prescription permitted compounding pharmacists to provide designer solutions of mild silver protein.
