I actually hold my head back and inject it into my nostrils while I am taking a shower. It hits the back of my throat and I swallow it. I never heard of anybody doing it. I invented it myself!

"gargling with a little hydrogen peroxide"

I agree once in a while. This is by far the best mouth wash. Have a toothache this often fixes it.

Yep, and if you don’t want the full strength stuff, you can just add a little to the cheap mouthwash you buy at the dollar store.

Swallowing small amounts (one or two cap fulls) of it is even more effective, since it gets further at the back of the throat.

I was gargling with it once, and momentarily distracted I and put the cup aside on my desk, and forgot it. Later, I mistook it for water drank the full amount - a mouthful - with no ill effects.
