what I saw when I looked it up, u can start it at 32 weeks and it's suppose to help prepare ur uterus for labor. and that most women who have drank it or taken the pill form of it have like 2-5 hrs or stage2 labor, pushing. also read that it helps you produce breast milk and lots of other stuff. even for women who aren't pregnant. but then again this is all off the Internet lol that's why I was asking everyone

What does it do? Like what's it's main purpose?

you drink it when you are further on after your doctor does a membrane sweep.
