I have used FOOD-GRADE and industrial-grade more than six years. It is true that hydrogen peroxide can heal many ailments. 35% Hydrogen Peroxide is used world wide in municipal water supplies instead of chlorine to disinfect and stop the growth of unwanted organisms.
I also use concentrated solution (35%) (easy for storage) and I must dilute it down to <3% before use.
You need to understand it before use it!

Colloidal Silver - Another Miracle
So why haven't you heard of it?
I suspect the user friendly economics of Colloidal Silver may have something to do with its low profile in the media. Colloidal Silver can't help but shine a spotlight on the expensive and deadly nature of our pharmaceutical industries, who are bigger than the Pentagon economically. For example, the pharmaceutical cartel's relentless promotion of dangerous vaccines for humans and animals through government programs have now been linked to everything from increasing crib deaths in infants (who in many documented cases scream for hours before dying), to the increasingly common disease, feline leukemia, in house cats. Colloidal silver, on the other hand, is a safe and reliable alternative to expensive pharmaceuticals.
