:The problem with this article (like others on plants which can be used in "popular medicine") is that it constantly gets "information" added which is not linked to a reliable source, largely in the "Medicine" section.  Right now it's not too bad, so I agree the tag could be removed. 
 :On the other hand, the "Medicine" section is very bitty, often seeming like an unconnected series of sentences, so I find it hard to see that it really is a good article now.
