We don't have extensive studies that injecting bleach helps as well.
There is a huge liability to those companies if it would end with deaths or health issues ("Facebook only looked for profits and didn't care that people were killed by misinformation")
You should not get medical advice from social media, and Facebook is also not the right place to discuss medical research.
Ironically few days ago people here commented that HN was linking to a rant on Facebook about performance in Python affected by shared libraries.
FB was considered not suitable for that kind of discussion and link was changed to bug database, yet some people don't have problem about discussing medical treatment there.
Just to be clear, if we changed a URL from one source to another, that would be rooted in 10+ years of HN moderation practice and would have been about the specific articles, for example we would tend to replace a "rant" with a more substantive/original source. It would imply nothing about FB being "considered not suitable". Plenty of FB articles have been discussed here over the years; though there tend to be issues with login walls and whatnot and I think the community tends to prefer the open web for content.
