i saw some interesting web stuff on why some people consider it kosher though generally humans aren't (kosher). i think it had to do w/ the fact that no animal dies-- it's a meat of life, so to speak. also they talked about breastmilk as being parve-- can have it w/ meat, unlike regular milk-- so that was an argument for eating placenta being okay in kashrut. thanks for posting the wikipedia article, quietserena-- super interesting! i'm tired, hope this all made some sense.
