Hi ho! Colloidal silver to the rescue!
Colloidal silver combined with certain antibiotics has shown to have a 100% increased efficacy in certain cases.
CS interferes with the reproductive process of bacteria.
I used a similar product on some nasty spider bites, (lesions to 3/4 inch diameter, through to meat, but arrested there by debrieding, H2O2 irrigation, and the silver gel--it took 3 months for the last to scab over but no infection), and it was great.
From time to time the lesions would feel like someone putting a cigarette out me (unfortunately, I know how that feels, too), and the silver gel immediately soothed that pain as well--a welcome bonus.
