There are horse medicines with aspirin, too. Is aspirin now a horse medicine because it contains a common ingredient? Ivermectin is also literally used by millions of humans in countries all over the globe that have parasite problems, because it's an antiparasitic. My whole photo tour group was given Ivermectin when we went to Africa before covid was even a thing.

> Ivermectin is an FDA approved drug for use in humans to treat a variety of parasitic infections including parasitic worms, hookworm and whipworm. It may also be used as an effective treatment for a wide range of other conditions and as a treatment of onchocerciasis, intestinal strongyloidiasis and onchocerciasis or river blindness.
