The Katharos Institute is a French company that manufactures and markets its own colloidal silver through Amazon worldwide.
We have recently been expanding into the American market and therefore need to democratize our brand and our products there. We therefore need sales and reviews in order to assess the interest in our products and also to improve the quality of our colloidal silver thanks to the different reviews we receive on Amazon.

Here is also a description of the different appropriate uses of colloidal silver:

Colloidal silver is a product simply based on water and silver diluted in the form of particles in water by an electrolysis system which has numerous health benefits.

You can use it internally:
– Strengthening the immune system
– Natural treatment or prevention against colds and tonsillitis

Or externally:
– Natural disinfectant
– Natural antifungal
– Natural anti-inflammatories
– Very effective treatment against acne

Apply the product directly to your skin and let it dry.
