from the link above is a report from a CIA agent on Collidul silver again anthrax ad bubonic plague (2:47 in)

I'm not 100% convinced by all in this report and the pre-1938 formula and invive part being the only good stuff. The part about Silver being +1 and other metals being +2 is just where it is in the periodic table. Two silver ions can still bond with one oxygen ion.
Going to the guys website links straight to a sales link (always a alarmbell ringer)...
What are other peoples views who have a science background?
A bit more digging gave me these two links:
http://www.silvermedicine.org/mild-silver-protein.html
http://www.silver-colloids.com/Pubs/protein.html
Both saying slightly negative things about Silver in protein solution which conflict again the report...
I still think good food, stress free living and good quality home made CS will benefit in times ahead.
