If your new to silver this is a very good site imho. http://www.oligodynamic.com/history.html The whole site is interesting although I've posted most of it before. Except for the little tidbit below. Seams like silver should give stem cell research a run for it's money. A project begun in the early 1970's by Robert Becker, an orthopedic surgeon, involved a silver nylon product. This project was instigated in order to find an electromagnetic shield. Instead, it lead to the revolutionary discoveries by Becker of silver's unique properties to increase the rate of tissue regeneration in diseased or damaged tissues and his discovery that silver ions could induce fibrocytes to dedifferentiate into stem cells and back again. Becker also addressed the fact that children under 4 years of age could regenerate fingertips with silver. His extensive studies suggest that the regeneration effect initiated by silver appears to be similar to that seen in salamanders, which regenerate lost parts.
