At this time, I must conclude that ionic silver works, and works well.  That's 
not to say I don't think particle silver has benefits as well.  Luckily, most 
processes that people use contain both.

With H2O2, the easiest test for benefit is against ear infections.  There IS a 
synergistic effect that can be demonstrated in combined use.  Normally, those 
who use hydrogen peroxide in the ears use it at 3% strength.  Adding a few 
drops of colloidal silver to a 1/2 ounce of 3% hydrogen peroxide certainly 
causes a noticeable change when the H2O2 CS mixture reaches the infection.  In 
fact, with more severe infections, it can be painful!  The solution is to cut 
the 3% H2O2 down to about 1.5%.  I have yet to meet an ear infection that did 
not respond incredibly well.

If I make a batch of colloidal silver with the 9 volt battery method ( where 
quite a bit of particle silver is deposited in the distilled water ), and use a 
glass dropper to extract some colloidal silver to another container, then use 
that same dropper to siphon some H2O2, a reaction is very evident in the glass 
dropper.  I know that many believe that particle silver is ionized through this 
process.  At this point, I tend to agree.  When using colloidal silver 
internally, if I want the added benefit of the H2O2, I only use an incredibly 
miniscule amount of H2O2.... In the range of an end solution with .0015 - ~ .05 
% hydrogen peroxide.  Usually, I don't want the 'stomach' reaction that is 
often present when using H2O2 therapy orally.  No need to upset the stomach at 
all.

Clearly more work needs to be done in this area - but it is all fascinating.
