Welcome

We're not The Onion! Not affiliated with them in any way! Not operated by them in any way! All the news here is real!

The Rules

Posts must be:

  1. Links to news stories from...
  2. ...credible sources, with...
  3. ...their original headlines, that...
  4. ...would make people who see the headline think, “That has got to be a story from The Onion, America’s Finest News Source.”

Comments must abide by the server rules for Lemmy.world and generally abstain from trollish, bigoted, or otherwise disruptive behavior that makes this community less fun for everyone.

And that’s basically it!

So, methylene blue can be used as a fabric dye; it can also be used as ink for temporary or permanent tattoos. However, medically, it's used in the treatment of methemoglobinemia, as a urinary analgesic, anti-infective, and anti-spasmodic agent, or in endoscopy as a gastrointestinal dye, and can also be used as a rescue antidote in life threatening poisonings causing refractory shock states and other shock states.

While I sincerely doubt anyone's state IV cancer has been cured by methylene blue, dismissing it as "a fabric dye" is wrongfully dismissive of it's actual medical uses.
