Let’s explore how castor oil or castor oil packs might support your journey in trying to conceive. Maybe you’ve seen it on TikTok. Or maybe you’re clearing out the forgotten section of your toiletry drawer. Castor oil packs, a popular method, have shown various benefits for users. They are often linked to enhancing health and have a reputation in alternative therapy. In any case, castor oil is a versatile natural oil with many benefits used in numerous home and medical therapies.
Fertility can be mysterious, and the road to conception can be difficult. If you’re unsure of how to approach the subject and what steps to take, you can begin by learning the 6 signs of high fertility in a woman. Read on to learn more about castor oil, fertility, and the historical context behind this treatment.
While castor oil does have a legacy in the world of natural medicine, castor oil and fertility have little to do with one another. In fact, using castor oil during an active pregnancy can be hazardous, though some people use it to support their well-being in other ways.
While evidence defending the use of castor oil for fertility is lacking, other natural approaches could be effective in helping you conceive. But first, it’s crucial to understand castor oil’s properties and why you should exercise caution if you unearth it from your bathroom cabinet.
Can castor oil promote fertility?
To put it bluntly, no. There’s no research to suggest that castor oil can directly promote fertility, whether by spurring ovulation, enhancing egg quality, or otherwise improving your chances of conception.
That said, some uses of castor oil may indirectly support reproductive health in some people by:
- Improving circulation – Some people swear by castor oil packs for boosting blood flow to the pelvic area and abdomen. While this won’t augment your chances of conceiving, adequate circulation is beneficial for reproductive organs like the ovary and uterus.
- Supporting digestion – Digestion supports almost every other physical system, including the one that governs your hormones (a.k.a., your endocrine health). If your digestion is irregular or you occasionally struggle with constipation, taking castor oil orally may help improve your digestive health.
- Reducing stress – While the relationship isn’t necessarily causal, there appears to be a correlative link between excess stress and fertility challenges. Some people use yin yoga and herbal teas to unwind, while others feel most relaxed under a castor oil pack (more on this below). Additional methods to reduce stress include a fertility massage, meditation, or exercise.
Remember to keep in mind what is considered excessive exercise when trying to conceive, as you go through your fertility research.
Castor Oil Packs and Reproductive Health: What’s the Connection?
Since there’s no consensus from the scientific community on using castor oil as a fertility aid, where does the idea come from?
It’s likely the result of centuries-old applications. Castor oil has long been used in folk medicines for various reproductive purposes. Today, it holds two main roles in formal and anecdotal reproductive healthcare:
- Inducing labor – Ancient Egyptians used castor oil to trigger labor in pregnant people, and studies show this intervention can still be effective today. In one study of pregnant people, taking castor oil triggered 91% of participants to go into labor, with few or no complications. That said, this isn’t a remedy that should be used without medical supervision—particularly if you’re pregnant or nearing your due date.
- Alleviating menstrual pain – Some people use so-called castor oil packs to combat pain during their period. These oil packs use cloths soaked in castor oil and applied warmly to the abdomen. While many people say this technique helps with period pain, there’s currently no scientific evidence proving its efficacy.
Additional historical methods for fertility include botanical ingredients, learn more with top herbs for enhancing fertility naturally.
Can castor oil be used during pregnancy?
Castor oil is not recommended for use during pregnancy unless under the supervision of a healthcare provider. Here’s why:
When you ingest castor oil (either orally or topically), your body converts it into ricinoleic acid, a compound that has laxative properties. Ricinoleic acid can also stimulate receptors in the uterus, leading to uterine contractions, which could initiate early labor, even if you’re not full term.
Not only can castor oil be a hazard to your pregnancy, but it can also easily disturb digestion. Symptoms like nausea, diarrhea, and dehydration are all common with castor oil use. These can be risky side effects if you’re pregnant, especially if you already struggle with pregnancy nausea or keeping up with your fluids.
In short, castor oil is best used before or after a pregnancy, as well as after breastfeeding, when it’s less of a risk to your health and the health of your baby. Consult with a professional to ensure the safety of using castor oil and learn more about the safe use of essential oils during pregnancy.
4 Uses of Castor Oil (and How to Use It Safely)
While castor oil isn’t necessarily an asset for fertility, it does offer a range of applications that may support your well-being pre- and post-pregnancy.
#1 For Period Support
If your healthcare provider gives you the go-ahead, you may want to give a castor oil pack a try! Members of the castor oil pack fan club say it soothes bloating, cramps, and pelvic discomfort during menstruation.
Here’s how to prepare one:
- Fold a piece of flannel or cotton cloth so it forms a pad.
- Soak this in castor oil until it’s saturated.
- Apply your castor oil pack to your abdomen. Some people cover the pack with plastic wrap to assist with absorption.
If you have one, you can place a heating pad on top of your castor oil pack to add to the relaxing experience. You can use your pack for 45 to 60 minutes, store it in the fridge, and reuse it up to 30 more times.
#2 As a Laxative
While it’s not a wise idea to use it long-term, the FDA approves castor oil as a remedy for occasional constipation. Because it works to stimulate smooth muscle movement in your intestines, it can be an excellent method of moving things along.
Here’s how to take castor oil orally:
- Measure out between 15 and 60 milliliters (for adults) of castor oil.
- Take it on an empty stomach, ideally in the morning before your first meal. You can also mix it in with a juice or other beverage (the taste of castor oil isn’t for the faint of tongue!).
- Wait 2 to 6 hours, after which you should feel ready for a bowel movement.
But remember, this method isn’t advised for people who are pregnant, nursing, or currently on their menstrual cycle.
#3 As a Skin Moisturizer
While ricinoleic acid works to stimulate the uterus and digestive system, it’s also a monounsaturated fatty acid—meaning it may work well as a topical moisturizer. It can even be found in some store-bought lotions and other cosmetics.
That said, not everyone’s skin agrees with castor oil as a moisturizer. In some people, it can cause irritation or even allergic reactions like rashes.
If you want to try it out, it’s best to perform a patch test by applying a small amount to a small area of skin first. If you don’t notice any adverse reactions, try applying it topically to a slightly larger swath of skin and massage it in.
However, if you’re acne-prone or have oily skin, you may want to avoid castor oil altogether, as it can clog pores and lead to breakouts in some people.
#4 To Treat Wounds
Castor oil has some anti-inflammatory properties that may help speed up recovery for minor scrapes and injuries to the skin. To use it for this purpose, consult with a healthcare provider first. It’s also important to spot-check your skin’s response to castor oil before using it to reduce inflammation. Be sure to try a patch test before putting it directly on your skin.
Once these boxes are checked, you can treat your wounds like so:
- Clean the injured area with water and a mild, fragrance-free soap.
- Dry the area completely.
- Dab a small amount of castor oil onto the wound using a clean finger or cotton swab.
- Cover the area with a bandage.
Other Evidence-Backed Home Practices to Support Your Fertility
If castor oil appeals to you for its home-use friendliness, rest assured, the following methods can help support your fertility safely from the comfort of your home:
- Reducing alcohol and caffeine intake – In both men and women, excessive alcohol use is associated with reduced fertility. Overuse of caffeine may also be implicated in fertility struggles, as it’s associated with damaged DNA in male sperm. Scaling back your intake can help regulate your hormonal balance, supporting reproductive and overall health.
- Focusing on stress management – Castor oil packs are just one way to decompress from daily and chronic stressors. Other approaches include prioritizing sleep quantity and quality, integrating a daily movement practice, or trying mindfulness techniques to help you pause and unwind as you go about your day.
- Loading up on fertility-boosting nutrients – From omega-3 fatty acids to key minerals like folate, establishing a balanced, nutritious diet is key for supporting conception. Additionally, taking a prenatal vitamin 3 months before you conceive may help give your body the nutrients it needs to prepare for pregnancy.
