DO NOT TAKE ANYTHING without your doctor's approval! Castor Oil is an old remedy that mom's used when they're children were sick. Please always ask your doctor before trying something. If they want to induce your labor, they will do it safely. Don't try it on your own. Your baby depends on you and the choices you make. For your baby's health, this question should be directed to your OB/GYN.
