The issue is always that Silver plates out and its the negative charged ions that do the real killing.
So inside the human body a few things happen that don't happen in a test tube. The normal body function of making peroxides ionized CS again into doing more work.

The other is toxins, no matter what your own immune reaction is still the best way to heal your body and Silver in both forms will neutralize a ton of toxins..
