Well at least methylene blue is harmless. I used to put it in my coworker's coffee to turn their piss blue.

Good ol' sugar tits.

I support right-wingers who are dumb enough to believe this right to use this treatment (without forcing any doctors to do so, of course). It will only serve to diminish their numbers.

Totally misrepresented, you left out prayer

Methylene blue is the most surprising of them all. It's often used as a cationic stain (so it reacts with negatively charged stuff) for bacterial identification and "making cells more visible".

I barely understand how it works but also heard that is used intravenously for some anoxia issues by some smart doctors but with someone not suffering anoxia, that seems like a thing that you don't want in your body.

Edit: and as an aquarium dye to battle fungal infections.
