From what I understand, consumption of the placenta (placentophagy) either via capsule or actual eating, has become more common (although I believe it is still a fringe practice). I know that other mammals have been doing this after giving birth, but is there any scientific evidence that it benefits a human mother? I have read both those that say there are benefits and those that say there is no benefits so I'm confused.
I read that the possible benefits are that the placenta is obviously chalkful of vitamins and hormones that will help the mother to heal both physically and emotionally after giving birth. For instance, it could help prevent postpartum-depression? It contains oxytocin, which helps promote lactation for breastfeeding? It contains prostaglandin, which helps the uterus to revert back as much as possible to its smaller state?
But then I read that there is no evidence that it does either of these, and it's possibly just a placebo effect. That the placenta only benefited the fetus while in the womb.
I'm not pregnant or anything, I would just like to better understand this trend, and know the science behind it.
