I did castor oil
at 38 weeks when i was in early
labor. It is true, it does stimulate uterine contractions, BUT!!.., it won't dilated you.. I had extreme contractions..less than two minutes apart and was in labor, but I wasn't dilating.... so the docs sent me home in excruciating pain and j just went right back, they ended up giving me morphine to help me relax and dilate. I did try it and I wouldn't recommend it because it very well may just cause more complications...good luck..
