Evening Primrose Oil: A Natural Option for the End of Pregnancy
At Birth You Desire, we understand how eager many expectant parents feel in the final weeks of pregnancy. Whether you’re feeling physically uncomfortable, emotionally ready, or simply done being pregnant, it’s completely normal to start wondering about natural ways to prepare your body for labor.
One supplement that often comes up in conversations is evening primrose oil (EPO). It’s a plant-based oil rich in gamma-linolenic acid (GLA), a fatty acid that the body converts into prostaglandins—compounds that help soften and ripen the cervix. Because of this, many believe EPO can help prepare the cervix and possibly encourage labor to start. But what does the evidence say? And is it right for you?
What Is Evening Primrose Oil?
Evening primrose oil is derived from the seeds of the evening primrose plant. It’s commonly taken in capsule form, either orally or vaginally, and is especially popular among those seeking more natural options for cervical ripening and labor preparation.
While it’s marketed as a tool for “inducing” labor, it’s important to understand that EPO doesn’t cause contractions or labor to start suddenly. Rather, it may support your body’s natural process by gently encouraging the cervix to soften, thin, and dilate, particularly in the last weeks of pregnancy.
What the Research and Experts Say
The science around EPO is still emerging and somewhat mixed:
- A study published in the Journal of Nurse-Midwifery found no significant difference in length of labor or need for interventions between those who took EPO and those who didn’t.
- However, anecdotal evidence and midwifery wisdom suggest that when used with intention and guidance, EPO may assist with cervical readiness.
- The midwives at Nile Women’s Health Care and Mountain View Midwives include EPO in their holistic toolkit, alongside movement, hydration, rest, and emotional preparation.
It’s essential to note that no natural remedy is a guarantee, and EPO should never be used as a substitute for medical advice or professional support.
How to Use Evening Primrose Oil Safely
If you’re considering EPO, always consult your care provider first. Here’s a general overview of how some midwives suggest using it, though your recommendation may differ:
- Start between 36–38 weeks, depending on your pregnancy history and risk profile.
- Oral Use: 500–1000 mg once or twice daily.
- Vaginal Use: Insert one capsule (usually 500 mg) at bedtime, allowing it to dissolve overnight.
Using a panty liner can help with any oil leakage if using vaginally.
Who Should Avoid Evening Primrose Oil?
EPO may not be appropriate if you:
- Have a history of preterm labor or ruptured membranes
- Are scheduled for a cesarean birth
- Have certain medical conditions or are taking medications that could interact with EPO
- Have experienced complications in this or previous pregnancies
