Castor oil?

Hey ladies!

So this weekend I was in the hospital with labor. My labor unfortunately stalled at 4cm dilated and I'm not 39 weeks yet so the doctors couldn't legally induce me (even though they wanted to). I got clearance to try home-induction methods, like RRL tea and pumping, but I was wondering if any of you ladies have tried castor oil? I was thinking about trying it this week if nothing happens on its own.

Thanks much!
