We highly recommend you research the use of Colloidal Silver & Chlorine Dioxide on the internet, in books, or speak to a natural health practitioner. Please research uses for Colloidal Silver and Chlorine Dioxide, Alchemical Science makes high-stability fused solution 3000 PPM (parts per million) of Chlorine Dioxide and 500ppm of Colloidal Silver. The strength always varies from batch to batch, anyone claiming a mass-produced such solutions to always be a fixed PPM is perhaps not telling the exact truth.
