@Scienceisnotopinions @mcnado before it had been properly investigated, it wasn't such a far-fetched idea that ivermectin could have off-target benefits like mitigating covid symptoms. after all, weirder things have turned out to be essential medicines, like the compounds produced by mould (penicillin). there are also some existing medicines that work, even though we don't know how (like lithium).
of course now we know that ivermectin is useless against covid. but dismissing unusual ideas without investigating them could mean leaving future cures undiscovered.
