“In a study published in the Pharmaceutical Chemistry Journal back in September 1992, it was found that that several different preparations of colloidal silver showed amazing efficacy against the smallpox virus.
Two medical colloidal silver preparations were used, one called Collargol, and one called Protargol. The latter was apparently a diluted preparation.
The study showed a 700 times reduction in the concentration of viral particles when Protargol was applied, and a whopping 11,000 times reduction in viral particles when the more highly concentrated Collargol was applied.”
That’s because it is a topical antiseptic. It’s supposed to kill germs on surfaces.
But you don’t put antiseptics into your body.
