My doctor was amazed when I refused IV Antibiotics for my PLDS. I discovered Colloidal Silver and $29 and 20 days later, years of stiffness were gone. I had a bit of detox due to the spirochetes being expelled though. He was again amazed when I told him about Colloidal Silver because he saw my problems first hand. He had never heard of Colloidal Silver . No germ, bacteria, fungus or virus can build a tolerance to Colloidal Silver.
