I use this stuff all the time. We use it for scrapes and scratches when necessary, instead of Neosporin (or similar OTC ointments). This only kills the bad bacteria and leaves the good. Neosporin kills the good along with the bad. We also use the liquid version of Sovereign Silver and have been very happy with it. For those concerned with argyria, do your research first, do intensive research about the benefits of silver and different colloids.
