This particular tag was originally discussed here: Should we create a medical advice tag?
Questions asking for medical advice are specifically mentioned as off topic, so to me it makes no sense to have the tag medical-advice. The tag info even advises not to use it.
If we blacklist it it means that it is eliminated and it cannot be recreated.
So... blacklist it? Or keep it?
In the Biology and Cognitive Sciences Stack, where I am most active, self-help questions with a medical background are explicitly considered off-topic. In other words, those questions where a professional care giver should do a proper medical (physical or psychological) exam, are closed.
At Bio we can close vote as off-topic for the reason of:
Personal medical questions and health advice are off-topic on Biology. We cannot safely answer questions for your specific situation and you should always consult a doctor for medical advice.
Something similar may be appropriate here too I guess - in other words, not only the tag can go, all questions based on medical self-help should be put on hold imo.
I think blacklisting might be a bit extreme considering that there aren't that many questions tagged with it currently. I'm in favor of removing the tag from the questions and even re-tag the questions more appropriately if necessary.
