This is not a meme cure based on sketchy research. It appeared to be effective in a recent study in Brazil with 3,000 experiment participants (admittedly not enough, but more research is underway) and it has been covered extensively by mainstream (i.e., not totally crazy) news outlets.
By comparison, I recall that some of the studies that championed ivermectin as a treatment for COVID included experiment participants who were dead before the studies began.
Almost all drugs are tested in animals before humans. There's a huge overlap between "horse drugs" and "human drugs" (et cetera -- a snake of mine got infected by mites, and they don't make snake drugs, so the vet gave us drugs "made for rodents.") While certain drugs have been politicized, and that's bad, your comment is little more than an association fallacy driven by that same polarization. Please don't.
