ArgeSan® is elemental, colloidal silver. Some also call it nano silver. Several successful studies have been conducted with this silver.
In contrast to ionic colloidal silver, it is yellow like fresh apple juice. Good colloidal silver MUST have this color. It is permanently stable and works much better and longer.
We are not allowed to advertise what ArgeSan® can be used for, except for technical applications. Connoisseurs of colloidal silver know its value and its possible applications.
As good sources of information about colloidal silver, we recommend the following two books:
“With the Power of Silver” Author: Elmar Buder, available on Amazon.
“Colloidal Silver” Authors: Dr. Josef Pies / Uwe Reinelt.
ArgeSan® will fulfill all your expectations in colloidal silver.
