There is, apparently, something called placenta encapsulation which means making pills out of a placenta postpartum for the purpose of digesting placenta. People claim that these pills offer unique health benefits (I'm not aware of any scientific research that either confirms or denies this claim).
Assuming that there are no additives to the pill and the capsule itself is kosher:
1a- Strictly speaking, is a placenta pill kosher?
1b- Would it matter how the placenta is prepared (dehydrating it, powdered form, cooked, roasted, etc.)?
2- Are any distinctions made between the mother ingesting her own placenta or any other people ingesting the placenta?
3- If there are unique health benefits to ingesting placenta, does that change the halacha in any way?
