The list of "things the FDA once recommended but retracted" is many orders of magnitude shorter than the list of "things someone on the internet shilled that turned out to be incredibly toxic and probably not beneficial at all"
I mean, that's a useless number unless I know the list of things that the FDA once approved and then did not turn out to be detrimental to patient's health.
I'd be more surprised if it didn't happen more than once in 117 years.
