H2O2 safety :
It has to be food grade H2O2. The bottle I bought is 12%, this has to be diluted down to a maximum of 3% . I am starting with 6 drops of the 12%, 3 times daily in half a pint of water, this is way under 3%, 3% is for mouthwash and external use .. I hope no one ever puts 12% H2O2 in their ear undiluted.
Always use 35% food grade hp which can be bought at a health food store, dilute with 8 oz. of distilled water. start with 3 drops of hp in 8oz. water three times daily. I had copd, emphyzema, and other lung problems, they are all gone my dr says he can't believe it.
