Again, sincerely sorry for the delay.
The broth is made from placenta. Yes, placentophagy is actually a perfectly good source of nutrition to mammals, even herbivores, but in our day an age if the mother has plenty of alternatives to nutrition, it isn’t a necessary part of the experience. It was mother nature’s way of looking after the health of the mother, whose body is considerably weakened after birth and prone to postpartum infections. Of course, most people don’t know that you can eat the placenta, so they chuck it out or do with it as tradition demands, or get stem cells from it.
