Placenta Consumption

Traditional Chinese Medicine (TCM) has known the restorative value contained within the placenta for centuries. As with acupuncture (which I have benefitted from for years) I cannot begin to explain how it works. I can say unequivocally that it does have an overall wellness effect. So, why not in this case? What is inherently wrong with replacing nutrients; the same nutrients responsible for producing and nourishing a human being why not assist the new mothers healing process?
