Cervical ripening is the natural process of softening and opening the cervix before labor begins. Pregnant women that need labor induction, have an overdue pregnancy or encounter risks to their health or their baby’s health, such as preeclampsia or gestational diabetes, may need assistance ripening the cervix. In a study published by Complementary Medicine Research involving 96 low-risk women with term [39 to 40 weeks] pregnancies, half of the participants received a daily vaginal capsule of evening primrose oil prior to delivery; the other half received a placebo. The need for labor induction was significantly higher in the placebo group, showing that the vaginal use of evening primrose oil could be safe and effective for cervical ripening in low-risk, full-term pregnant women.
