I drink it all the time. Its the core of a real pineapple that has the labour starting enzymes but you'd have to eat a ton if it.
I never liked pineapple until pregnancy. I've never had pineapple juice before...Just seeing the title of this post makes me want to go buy some though!
Supposedly, it helps bring on labor, but I've been drinking it for almost two weeks, and I'm now two days past my due date. Not helping me at all. Sex, walking, and spicy foods haven't helped either.
