I found questions tagged as [medical]. Some 12 questions with 1 follower.
This tag has no info as I was curious to find out what questions it would cover.

What is the justified use of this tag? I saw a question on Ayurveda which is not relevant to our site. Use of such tag can cause ambiguity? I'm sure not all people who post questions go through the introduction page when they sign up.

All I could do in this case was to vote the question to close on blatantly off-topic I would like to know the purpose of this tag please.
