Castor Oil to Induce Labor

Hello mga mamsh! Just want to ask if anyone of you tried Castor Oil to Induce their labor? I kept on seeing via youtube that it helps induce labor. A lot of testimonies as well. This was usually done 39-41 weeks of pregnancy according to the vlogs I've watched. Please comment below if you have tried it. PS: I did ask my OB earlier about this and she said that it helps aid with labor but the result will give you diarrhea somehow because it is a natural laxative and if you're going to take it, it should be the one with internal use as well.
