There is NO damaging side to properly made colloidal silver. NONE! And, despite all the mainstream propaganda and disclaimers, there is no documented evidence of such damage. Even the improperly made, large particle contaminated silver that famous Blue Man Papa Smurff Karason took in huge quantities for years, did no damage except for his blue skin condition (which is actually reversible). In fact, what virtually none of the mainstream media shows will tell you is that Karason was invited by one show to take a physical, which he did - and the results gave him a clean bill of health.
The only danger colloidal silver represents is to the billions of dollars in profits to the less effective, truly dangerous and highly expensive antibiotics of Big Pharma.
