@akron3, please note that even food grade hydrogen peroxide should not be ingested.

The term "food grade" can be misleading, possibly making it sound like it is safe as food. It is not safe to swallow.

Food producers use 35% H2O2 for various purposes, like bleaching flour. And you may have seen peroxide in some dental products like toothpaste. However, no matter the dilution, even 35% H2O2, you should never drink any hydrogen peroxide.

Swallowing food grade H2O2 can cause serious side effects, including sore throat, abdominal pain. nausea, vomiting or possible internal bleeding.
