Colloidal silver saved me! I am allergic to all antibiotics. I had a HUGE boil of MRSA 4 inchs on the back of my neck and over my spine. I started taking the colloidal silver 1 tsp 4x a day and applying it to my neck and it healed me! I am a RN and exposed to superbugs every day. Silver is in medicines so it is effective to kill bugs. The pharmacutical companies just want people on the money making drugs instead of natural healing.
