I can't believe no one has mentioned the "Labor Salad!" Maybe they did and I missed it....
I've been eating it for a week because it's just a nice combo of leafy greens, and I need to keep things moving down there with my iron supplements. Well, and also on the off-chance that it actually works.

My midwife actually gave me a handout on "things to encourage dilation and labor" and EPO was on it (it said 3 caps per day vaginally----way more than I would think to use!), RRL, sex, and pelvic exercises. I guess she's seen them work a lot of times. She's been doing it forever, so I wonder?
