Silver works. I have used it myself and my daughters to fight ear infections. I treat my dogs with colloidal silver also when needed. It has been proven over and over again that it works and has been used for hundreds of years.

The World Health Organization (WHO) lists colloidal silver as being effective for disinfecting drinking water in third world countries, taking advantage of its anti-bacterial properties.
