"After several hundred cases, Dr. Becker believes that the technique works in three stages. The first stage is the chemical combination of highly active free silver ions with all bacteria or fungi present in the wound which are inactivated within 20 to 30 minutes. The second stage occurs over the next few days. Silver acts on fibroblast cells to cause them to revert to their embryonic state, becoming stem cells. These cells are universal building blocks whose role is to reconstruct new tissue. In the final stage, silver ions form a complex with the living cells in the wound area to produce immediately convertible stem cells. The end result of this conversion is that the stem cells supply all the building blocks necessary to completely restore all anatomical structures. "
