It’s still insane to me that people were actually doing that. I know meds like ivermectin and pyrantel are used in humans but still… Horses have BIG organs, and that paste is a suspension dosed specifically to get rid of equine intestinal worms. It’s not the same as the pill you get from a pharmacy.
Even if those people who ate horse dewormer felt no ill effects I bet there’s some organ damage in there. I’d hazard a guess that human livers and kidneys don’t like high doses of that stuff.
Was this some iteration of “straight men don’t care about aesthetics, they care about function” type of thing??
Because that’s such a boring existence. I’m sorry your dad hates aesthetics. I hope you’ve found your own tastes despite him.
