Castor oil to induce labor at 40 weeks?

i have been to my doc today and asked her and she said that castor oil does not induce labor! i'm glad i didn't tell her that i tried it a week ago, while being 1cm dilated. i took a dose with g juice, that stuff almost made me puke. and you know what it didnt even give me the runs. it was such a bad idea! i was so mad at myself for taking it!! it does not work to induce labor!!! people that say it worked for them i think it was just a coincidence thats all.
