On The Media did a really good segment with a journalist from Mother Jones of all places. She broke down the rise of Ivermectin and the whiplash response to demonize it even when, as you say, it is safe for human consumption and had at least some positive in vitro test results. As much as it is not worthy of being recommended as a treatment, it's unlikely to be harmful and has/had at least a slim chance of working.
