@BenA I'm an idiot. I thought someone had posted that here. I now realize it was a screenshot from another site. I showed a friend the discussion about what they should wrap the wound in. I'm reluctant to repeat what he said; he wondered if they were from a specific area of the country.
I was horrified when I read it because I'm tending to a slow healing wound right now. I got a tetanus shot and antibiotics and have done all the things a sane person would do.
