What's the use of placenta after giving birth? After my wife gave birth, the nurses asked me if I'm going to keep it. I was like: What for? I have no idea at all.

It varies from different people to people. Some people chose to have it made into pill for consumatiom because it is believed to have health benefits. Like Diana, I find it a little too gross for me to eat it even if it's clean and in a different form. Some, like the Muslims, choose to bury the placenta to protect the babies from evil. For me personally, I told them to discard it.
