Quoting Fawn Hurley:" if your late and want to go in labor some myths are riding down a bumpy road in the back of a truck haven ... [snip!] ... oil will diff. throw you into labor and once you go into labor stimulating your nipples will make your contractions come more."
castor oil will not put you in labor! it a huge no no. and may cause distress in the baby and cause him/her to have its first bowel movement in the womb. not a good idea, plus it will only give you the runs. it causes contractions in the intestines which can cause your uterus to contract, but uselly doesnt work and leads to dehydration and more issues then are needed. that is bad advise!
