Can Castor Oil Cause Miscarriage In First Trimester?
No but it could make you sick if you took too much.
Castor oil cannot cause miscarriage. It is an old wives tale. The use of Castor oil in late term pregnancy is not recommended by some doctors because of the risk of Meconium Aspiration Syndrome, though it is highly disputed. Hope this helps!
