Medicine man/Talk

Good to see someone writing articles about anthropology, an area in which Wikipedia has been pretty weak so far. I know almost nothing about this topic, so I don't really want to edit the article. But I do think this article needs a lot more of the cultural background of this term, re Native American folk healers. Also, it's hard to say this in a politically correct way, but anyway: many M.D.'s would deny that many people called "medicine men" are actually [physicians], in the main sense of this term, literally speaking. Moreover, under this definition, many M.D.'s would count as [medicine men], which they are not, literally speaking. --LMS
