Bioactive Hydrosol Silver Water Spray for Immune Support

At the start of October 2014, our founder Jean first learned about colloidal silver and was immediately captivated by its remarkable benefits. He was puzzled by the limited awareness of this solution among the general public. In response to this realization, the Katharos Institute was established with a clear mission: to educate the world about the exceptional qualities of this ancient product.
