Moreso they will plant it at home but you even have to be careful how you do that, as it is so rich in nutrients that it can actually kill the plant.
We planted DS placenta with a tree we had put in a few mths earlier. We thought the tree would flourish, but it nosedived for a few years, I figured it was probably due to the nutrients from the afterbirth being too much for it...

When we told my M/w we would be keeping the placenta she offered some things we could do with it, including getting methods for cooking it - but she let us know that if we ate it she did not want to be invited to partake. I asked her if that had happened to her before and she said yes.

I used to have a korean friend who told me that in Korea they traditionaly offer you soup in the morning, insted of having cake. She said it was to represent a soup made of afterbirth - representing the afterbirth from when you were born. Its meant to wish you good health as well as remembering the time you were born.
She was wanting to make it for a friend of ours for her birthday as a nice surprise , but I knew the surprise our friend would get would not be the kindly intention suggested
Nice idea, but I wouldnt want to eat placenta, and I wouldnt even want to eat a soup for breakfast that symbolised my own placenta!!!

I have no problem with anyone who chooses to do that though, however as far as it being like liver, my friends placenta that I saw looked like a big healthy liver, but my DS one looked fugly - not appetising at all Im sure it was healthy but I was dissapointed it didnt look like my friends one
