From the Research

Castor oil is not recommended to induce labor due to insufficient scientific evidence supporting its effectiveness and safety. The most recent and highest quality study on this topic is a 2022 systematic review and meta-analysis 1, which found that castor oil may have an effect on increasing the Bishop score and labor induction, but the evidence is not strong enough to support its use as a labor induction method. Other studies, such as a 2009 study 2 and a 2018 retrospective descriptive study 3, have also shown inconsistent results regarding the effectiveness of castor oil for labor induction. A 2022 double-blind randomized study 4 found that castor oil may be effective in initiating labor in women with a previous cesarean section, but this study has limitations and more research is needed to confirm these findings. It is essential to prioritize safer, medically supervised methods for labor induction, such as membrane sweeping, prostaglandin medications, or oxytocin (Pitocin), which have been shown to be effective and safe in various studies, including a 2000 study on oxytocin for labor induction 5. Always consult with your healthcare provider before attempting any method to induce labor, as they can assess your specific situation and recommend appropriate options based on your health and pregnancy status. Some key points to consider when evaluating the evidence on castor oil for labor induction include:

  • The lack of strong scientific evidence supporting its effectiveness and safety
  • The potential side effects of castor oil, including severe diarrhea, dehydration, nausea, and vomiting
  • The availability of safer, medically supervised methods for labor induction
  • The importance of consulting with a healthcare provider before attempting any method to induce labor.
