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.

Jason or anyone,
Do you mix this for a one time application?  Or can you mix CS and H202 and 
use when needed?    What is the approx. shelf life of this mixture?   Was 
wondering if H202 would loose its "fizzle" in storage.
Thanks
Terri
