The medical establishment is conservative for good reason. You don't just pick a drug and start touting it as a cure all. And you certainly don't publicly propose it with little to no evidence.

From what I have seen in the media, they have correctly reported that the drug was being recommended by non-doctors and with little evidence. They may have gone too on the other side but given a lack of evidence the default assumption should always be that a drug is harmful until proven otherwise.
