From the brand
It was in October 2014 that Jean, our founder, heard about colloidal silver for the first time. Taken aback, he discovers its incredible merits and wonders why this solution is so little known to the general public. It was in the face of this observation that the Katharos Institute was born and it has a clear mission: to make the world aware of the extraordinary qualities of this thousand-year-old product!
