Studies, Risks, and Dosage for Inducing Labor with Castor Oil

How to induce labor with castor oil
How to induce labor with castor oil

How It Works

Castor oil is a liquid laxative that you can find in most drug and health food stores. There are three main ways it works:

  1. It induces contractions in the bowels, which in turn can cause the uterus to to begin contracting as well.
  2. It dehydrates the body, which can also cause contractions.
  3. Scientists have discovered that ricinoleic acid, a key component of castor oil, targets prostaglandin receptors on smooth muscle cells in the intestines and uterus to stimulate contractions.

Before Inducing Labor With Castor Oil

  1. Try other methods first. Other forms of natural induction can be a lot more pleasant and won't have as many potential side effects.
  2. Don’t take too much. Never take more than 1-2 tablespoons (max 1 oz or approx 30 ml) in a 24-hour period.
  3. Drink lots of water, as castor oil is a laxative and will dehdyrate you.
  4. Don’t induce early. If your body is not ready to go into labor it will not work. Unless you have a good reason (discomfort is not a good reason!) don't attempt this before 40 weeks. If you're facing medical induction, make sure you're aware that it's within your rights to refuse or ask for a later date.
  5. Only take it to induce. Do not take it as a way to speed up labour. Doing so can make birth even more painful.
  6. Do it at your own risk. Talk to your medical professional if in doubt.

Castor Oil Risks, Dangers, and Side-Effects: Meconium

If you research castor oil induction thoroughly, you'll find that there are two camps. One camp claims that castor oil may have the same laxative effect on the baby as it does on the mother. As such, using the oil to induce may increase the chance of meconium – the baby’s first stool – being passed during labor. That can potentially be harmful to the baby if it’s aspirated, or inhaled into the lungs, potentially causing pneumonia or some developmental delays. The second camp claims that castor oil labor induction has no relation to passing meconium.

This is still an area of controversy, so you’ll want to look at the research and make your own decision. But these are the facts that I’ve found, which can help you make your own decision.

  • Babies born postdate (40 weeks and over) have a higher chance of passing meconium in the womb because their bowels are more mature.
  • Babies born without using castor oil to induce labor can still pass meconium in the womb (at any gestation date).
  • Babies born with castor oil labor induction often do not pass meconium in the womb.
  • No well-documented study has linked meconium and castor oil labor induction or proven that (these types of) laxatives can pass through the placenta in any form.
  • Approximately 57% of women who take castor oil go into labor. Remember this is a statistic only and may not take into account how far along they were or other conditions such as prelabour or other forms of natural induction.

But Isn't Castor Oil Used for Abortion?

Another common argument against using castor oil is that it’s an abortifacient. While true, it’s somewhat beside the point: abortion and induction share the same basic goal of evacuating the womb. Many medical induction aids (including pitocin) are also commonly used in abortion.

Medical Opinion on Castor Oil and Labor

Even medical opinion on the subject varies widely. Some obstetricians and midwives regularly recommend the use of castor oil to induce labour once a woman passes 40 weeks while others discourage or strongly warn against it.

Until the last few decades, castor oil and soap enemas were commonly used in hospitals to induce labor. However doctors discovered other methods of induction that had higher success rates because they were more forceful on the body.

If you do have a high-risk pregnancy or are ill, it's a good idea to either seek medical advice or avoid castor oil as an induction method.

Studies and Medical Links Regarding Castor Oil Induction

If you want to do more research on your own - which I recommend - you may want to start with some of the studies below.

  • Castor Oil Literature Review: This meta-analysis reviews the biggest studies on castor oil inductions, offering an overview of the current research on the subject.
  • Castor Oil Increases Labor Onset - This study finds that women were more likely to go into labor within 24 hours of taking castor oil.
  • Castor Oil Study On 600 Women - This study found that there was no big difference in likelihood of going into labor between those who did or did not take the oil. However, the study also found no harm to the infants either.

According to a 2012 research paper in Proceedings of the National Academy of Sciences,scientists have discovered that ricinoleic acid, a key component of castor oil, targets prostaglandin receptors on smooth muscle cells in the intestines and uterus to stimulate contractions,

The well known guide "What to Expect When You're Expecting" simply says on the topic of Castor Oil induction:

Castor oil. Hoping to sip your way into labor with a castor oil cocktail? Women have been passing down this yucky tasting tradition for generations on the theory that this powerful laxative will stimulate your bowels, which in turn will stimulate your uterus into contracting. The caveat for this one: Castor oil (even mixed with a more appetizing drink) can cause diarrhea, severe cramping and even vomiting. Before you chug-a-lug, be sure you're game to begin labor that way.

What Does Castor Oil Taste Like?

Castor oil is a thick liquid which some people do not like the taste of at all. Others say it is nearly tasteless.

It is a thick, clear, oily liquid similar in taste and consistency to cooking oil. Some report a soapy taste as well.

Castor Oil Side Effects

  • Diarrhea - Since castor oil is a laxative, this is a very common side effect.
  • Vomiting - A small number of women also vomit due to the strong effect of the oil.
  • Cramping - The bowel will usually cramp due to the laxative effect of the castor oil but not everyone will feel it. Some women will experience violent cramps however.
  • Nothing - some women will not experience any side effects at all.

Castor Oil Preparation


  • Make sure you have plenty of water available to keep you from being dehydrated.
  • Be close to a toilet.
  • Have your hospital bags ready.

How Long It Takes

It takes anywhere from two to six hours for side effects to begin. Side effects can last from one to six hours. It can take from 5-24 hours for castor oil labor to begin, if it's going to.

Benefits of Castor Oil Induction

  • You don't need to be dilated or engaged for it to work.
  • Your system is clean so that it's unlikely you'll have any "accidents" while pushing during labour, except in the rare cases where labor begins very fast or was about to begin when you took the castor oil anyway.
  • Although stronger than other natural induction methods, castor oil still will not put you into labor unless your body is ready - unlike a medical induction.

Castor Oil Dosage and Methods for Induction

Many people recommend taking half a cup or more of castor oil. Personally I'd only recommend taking 1-2 tablespoons at most. As long as you take enough to make the castor oil do it's job, you don't need to overdose on it and, in fact, taking too much can lead to severe dehydration.

There are plenty of ways you can take castor oil, it's completely up to you. Here are some suggestions:

  • Mix with orange juice or a strong flavoured drink to cover the taste.
  • Take as a shot then chase it with something to remove the taste.
  • Drink over ten minutes either mixed or in small straight amounts.

My Experience

I decided to try castor oil as a last ditch effort when I was at 41 weeks. I was scheduled for a medical induction at 41+3. According to the doctor just three days before, I was undilated and the baby wasn't completely down in the birth canal.

I drank one tablespoon of castor oil at 3pm in the afternoon. I was running to the toilet from approx 5.30pm to 7pm and then had no more side effects. I cleaned my house so I was ready, just in case, and about 11.30pm I decided that it was time for bed.

I lay down on the bed and immediately had my first contraction. This was followed by a second contraction two minutes later. We arrived at the hospital and my baby girl was born 4 hours later, a healthy 8lbs, 4oz and with no complications. She had an almost perfect Apgar score of 9 followed by a 10.

In hindsight, I would not induce labor with castor oil again, because now I'm aware that I can refuse medical induction. However I would still personally choose it instead of pitocin in the event I needed it.

If you're going to try inducing with castor oil or have already, I'd love to receive a comment below with your experience.

I tried with four ounces of Castor Oil, mixed up in a fruit smoothie, and drank it fairly quickly. Getting it down wasn't bad, and I didn't get sick. A few hours later I got pretty intense runs, and was very careful to drink a cup of water between every trip to the bathroom. I had some contractions about twelve hours later, but they only lasted about two hours, and then quit. No baby for me yet. I have very stubborn babies apparently.

Natalia 14 months ago

Unfortunately I had negative experience with castor oil. I mixed 2dl of peach juice with 1,5 table spoon of castor oil. In two hours, the side effects started: strong diarrhea, vomiting, very strong cramps (difficult to identify if it was womb or intestines), subsequently blood in mucus from intestines. All lasted over 3 hours. It was the strogest, most painfull diarrhea I have ever had in my life and I am heading to doctor tomorrow morning. So far, I did not went to labor. I am in week 40+5, dilated on 2 fingers. I believe that it helped many women, but please be careful when using.

Heather 15 months ago

Hi, I'm a doula and student midwife, and I would never recommend taking castor oil without some form of protein. Usually we mix it with peanut butter on toast or a cup of Greek yogurt. The protein helps reduce or even prevent diarrhea from the castor oil, as well as a lot of stomach discomfort. Juice does NOT do this, in fact it can increase your diarrhea. Just something you may want to add!

Angel 21 months ago

Hey, I just read through all of these comments and I still have questions. I took 2 tsp. today around 6pm. Then by 7pm I got randomly extremly tired and when I walked around I felt weird. I went to bed and woke up around 9pm going straight to the restroom. I have felt sharp stabbing pains maybe 2 times in my lower abdomen, but that's about it. My son is moving like crazy. I was just wondering if anyone thinks it's working, or if I'm just getting the normal symptoms from it?

Nate 23 months ago

I had castro oil with my second child, 5 days before due day. I took 2spoons of castro oil with orange juice around 7 pm., at 12am my contractions started and at 3am I had a beautiful, healthy daughter. I believe that castro oil definitely helped but made it very painful and very fast. They had to give me pitocin to help my uterus contract since I was bleeding excessively. Not sure if that had anything to do with me drinking castro oil. I feel like castro oil did help me to go in labor but made it very painful. Do note that I deliver my children naturally with out epidural. I am 38 weeks right now with gestational diabetes, not on meds but monitoring my diet and checking sugar 4 times a day. I have very hard time keeping with my diet. I was told that my baby was already 7.5lb at 34 week ultrasound. I am trying to avoid castro oil but it might be a good idea in my case.

When I had my first child I took castor oil and it worked awesome. I tried the orange juice mix but couldn't bring myself to drink any of it. I found that making a waffle and mixing syrup and the castor oil and pouring it on the waffle. It helped a lot I couldn't even taste it and within a few hours I was in the hospital in labor.

Brittany S. 2 years ago

I took 2tsp of castor oil mixed with apple juice with my first child around 8pm and my water ruptured around 6:30am. I wasn't having any contractions or pains but I decided to go to the hospital anyway around 9am. I was 4cm(I was 3cm the day before at my check up). I wasn't dilating anymore so around 5pm the went in and broke the rest of my water. I had my healthy baby boy at 6:08pm without an epidural. I'm currently 37weeks and if this baby boy don't come on his own I will definitely try castor oil again to avoid being induced.

Christina 2 years ago

I used castor oil at 40w+1, (after walking around for almost 2 weeks at 3cm. dilated & 95% effaced) with my firstborn in 2006 & confused what I now know were contractions with THE WORST urges to use the bathroom I'd ever experienced. I had taken a spoonful with pineapple juice around 8:00 p.m. & from midnight until about 5:00 a.m. was periodically on the toilet. I remember thinking to myself "Could this be it?" & trying to time the cramps, but as tired as I was in those wee hours, I didn't really see a pattern.... Until the "cramps" were 2 minutes apart & I couldn't stand up straight or talk during one! Made it to the hospital at 9cm. ready to push & had my sweet boy an hour later. No meconium, a 9 on his first APGAR & a 10 on his second. (They also offered an epidural, but at that point, I just wanted it to be over with!) Would I use the same method again? Absolutely! Did I have to with #2? Nope. He made up his brother's deficit & came 2 days early!

Lisa 2 years ago

Hi, thanks for this post! I'm just wondering if this will work if one is not dilated? I'm 41 weeks, baby is 3/5 engaged, cervix is soft, slightly effaced but not really dilated. Does this matter or can it still take effect.

Steffi 2 years ago

In 2012 with my first son I took castor oil 3 days before my due date around 2pm and 2hrs after had a little diarrhea. About 2 hrs after that I started with contractions. I went in that night and was only 2cm. I walked around the unit and was then 4cm n they kept me. My son was born the next day. Now I'm 39+4 due in 4 days. I took castor oil today at 8am today and nothing so far and it's 945pm. My hubby bday is in 2 days so maybe my son is waiting to come then.

tiffany 2 years ago

I'm 39w3d and tried using castor oil. I've never taken a laxative in my life so wasn't sure how I'd react to it but I think it all depends if your body/baby is ready. I tried everything to kick start labor and this was the last thing on the list. I took it and nothing happened. I didn't even get sick or have to use the bathroom or get any cramps or anything. I guess I'll just have to be patient.

I'm 40 weeks and 3 days and I'm having hip pain and pelvic pain. I went to the midwife today and she said it wasn't open enough for her to even strip the membrane. I'm 1 cm dialated. I'm bout to drink some Caster Oil. I hope it works and I have a safe delivery. Wish me many blessings!!!

Oh also forgot to say I've tried every other form of natural induction (spicy food, sex, message, accupressure, walking, exercise ball, raspberry leaf tea, evening primrose oil pills, nipple stimulation) everything and nothing has worked, I've just got a very stubborn baby.

MamaEmm 2 years ago

I've received 2 due dates, both which I am past due (10/31/13 and 11/07/13) I'm scheduled for an induction this Thursday (11/14/13) but I decided to try castor oil tonight for the second time (tried it on Halloween(first due date) and nothing happened except severe contractions/false labor ending in a hospital visit and sent home after 4 hours of monitoring. Now being over due for both due dates I figured I'd give it a try. Took the oil at about 8:30pm went tobed and woke at midnight with tight stomach and a lot of pressure so I got up and spent about 10 mins straight on the toilet. After I took a hot shower, now I'm relaxing and watching a movie having some pressure and random contractions. Really hoping this is it. I've had a really rough pregnancy and don't think I'll ever get pregnant again. But this post is extremely helpful and the best one I've found and I did a lot of research and I must say kudos b.c this is by far the best!!

Used castor oil with my 4th baby as I was told they wouldn't induce me because of 2 c sections 10 years before.I took it on due date at 11 pm and went into labour within an hour.had baby 2 days later due to baby being back to back will be using it again with baby no 5 xx

Those of you who have used the castor oil before, can you tell me if you've ever been concerned that it affected your child's health? Especially your child having tummy issues when they're a few years older...just a curious mommy.

Katrina Rae 3 years ago

My due date is tomorrow, (fathers day!), I have tried castor oil twice with little to almost no side effects. (Which I guess could be a good thing considering some horror stories I have heard). I have not gone into labor yet and the last time I took it was almost twenty four hours ago. It did give me a little tummy ache, but beyond that didn't do much for me either time. The one I purchased is tasteless and odorless, but the texture is still hard to choke down. I don't think I'll ever take it for anything again. This was a last ditch effort for me, it wasn't my first choice, but nothing else had worked. I guess my baby girl is going to come when she pleases!

Gina Croote,

In that case yes, I don't think it can hurt to try. Leave it as late as you can... possibly in the last 5 days before the planned induction and make sure you are careful.

they have told me that she is in the 3% group of the size she needs to be they said she is a good weight as far as the fact that the rest of her measurements are small as well they have me doing the NSTs 2x a week now and that's why they are saying inducing at 39 weeks cause she would have a better chance of growing better out of womb. this is actually my 3rd pregnancy and i had no problems at all with my two boys.

WryLilt profile image

WryLilt 3 years ago from Toowoomba, Australia Author

Gina Croote,

Effacement and dilation is NOT an indication of anything. In fact, you can be 2-3cm dilated for several weeks or not dilated at all just hours before having your baby. Some medical professionals don't do internal checks at all for this reason.

Have they actually given you PRECISE information about your baby's growth? If it was really serious, they wouldn't be telling you to wait another few weeks for induction. Baby size estimates can be up to a pound or more out EITHER way.

The longer baby stays in the better, and they cannot force you to induce if you don't want to. I'd recommend making sure your doctor has a clear reason on why he wants to induce as often it can put you at higher risk if it's not needed.

I am 35 weeks and 6 days. Last i got checked i was not at 1 cm dilated and 50% thinned i have been having BH for the past week straight some are really strong and some are not. I am not thinking about going this way right now but maybe in like 2 weeks i might do it cause they are saying that come 39 weeks they will induce me cause they claim my baby is small and something about growth restriction. I was just wondering if i should try this way or not. I am not big on the hospital inducing me if i can go into labor with out it.

anj 3 years ago

great article and i appreciated your personal experience at the end. i have two children who both went to 41w1d before i drank castor oil. with my first baby, a hospital induction was looming, and i badly wanted a natural birth. i succeeded. for my second baby, i had a homebirth with midwives so i was not under pressure, but was experiencing a lot of prodromal labor so i decided to go ahead. in both cases, i drank it in the morning and had a baby in my arms that night. 8'11oz first baby, 8'5oz second baby. im now 40w5d pregnant and planning my third castor oil induction on monday. i would like to go into spontaneous labor for once, but am grateful for a method which to me is tried and true!

sneetches 3 years ago

I was 41+6 with my second baby and getting pretty tired, with emotional strain on the family and various people (though not my midwives) starting to nag me about the dangers of waiting longer. Also, I really wanted to make sure nothing interfered with our plans to have the birth at home. Our midwives had just done their weekly check up so they were very nearby, and it felt like a really good day to have the baby. Also, I had had some indications that morning that labor might be soon, but over the previous couple of weeks I had thought things were moving along only to be disappointed, so I was wanted to take some steps to encourage my body to follow through.

So, long story short, when the midwives put castor oil on the list of possibilities for me to consider, I decided to go for it. I also took some herbs under their direction, so it's possible that the effects I experienced were not the castor oil alone. But in any case, within half an hour of taking 2 ounces of castor oil I started feeling strong contractions in my back, within an hour and half post-castor oil I had contractions spaced 3 minutes, and in just about exactly four hours after the castor oil the baby was born with just 15 minutes of pushing.

Apparently I'm the only person in history to have had no effect on my intestines from the castor oil. I was constipated before the birth, had a small amount of firm stool during the birth, and remained constipated afterward. Odd. But in any case, the birth was seamless -- painful, but no more than the previous non-castor-oil time, and much faster, which was a blessing.

Great post and I will confess I am the mother of TWO castor oil induced babies. I THINK what is most important to highlight a gabazillion times is that if your body is NOT ready for labor castor oil will not force you into labor. Thank you for stating that.

I enjoyed reading your article and can't tell you how many people feel the need to share their opinion on how harmful it is, how selfish I was, how horrible it is etc. I basically keep hush, hush on it unless asked directly. It's deifnitly one of those 'need to know basis topics.

Nicole ,

Unless there is a medical reason, there is no reason you need to have a c/section just for going postdate. And it's not a good idea to have castor oil if you're already in labour (as stated at the top of this article) as it can make labour quite painful and messy.

Nicole 3 years ago

I'm 38weeks as of today, my scheduled c section is may 2. A few days ago I went in the hospital and found while I was there that I was already dilated at 3cm and 70% Effaced.

While I was there I dilated to 5cm still 70% effaced.

They sent me home because my labor stalled after that.

I took 2tbs of castor oil earlier, could it help get things back on the road.?

Desiree Abrams,

That's FAR too early to try. It probably won't work anyway (it only works if you're ready.)

At that gestation, babies will need to be in the NICU, have double the chance of infant death in the first year, miss out on important mental development and so much more. Not to mention probably needing steroids to mature their lungs at birth, and a feeding tube.

I strongly recommend waiting to give your baby the best start to life - it's only a few extra weeks for you, but it can change their health for a lifetime.

WryLilt 3 years ago from Toowoomba, Australia Author

Stacy, I think it's far too early to be trying the castor oil. Since a first pregnancy is up to 80% more likely to go postdate (and you're NOT overdue till 42 weeks), don't try and force your body into something it's not ready for.

Stacy 3 years ago

It is 3:20 am. I drank the castro oil at about 1pm, then a little more at 3. I went to the nathroom a few times and I'm feeling contractuons every 7-4 minutes consistantly for about 20 minutes and then they only come every 20 minutes.Amd then back to just several minutes apart. Could this be early labor and mean I'll be in full blown labor in judt a.few hours? This is the first thing I've tried.that gave me conttactions. I've fone a lot of walking, sex, cleaning, nipple stimulation but nothing ever happened until now. I will be 39 weeks tomorrow.

You can be dilated for weeks before birth - internal exams are nothing but a stress on the mother whether before or during labor.

EDDs can be up to 2 weeks out depending when you ovulate, so I'd recommend at least waiting till 40 weeks. This is an important time in baby's mental development.

Samantha, it's really a personal choice.

I did my research before using it and I believe that a lot of the "horror stories" are from women who don't even bother to research, who take far too much castor oil and don't bother staying hydrated, or take it far too early.

So do your research and have a good look at both what people do and don't say - everyone has an opinion but not every opinion is based on more than hearsay and incorrect usage.

Im 38 weeks and ive been reserching Castor oil a lot and a lot of ppl say its ok and they went into labor the day after or acouple hours after then a lot of ppl say no you shouldn't use it it didn't work..ect. Im not planning on using it unless i go over my due date but im kinda scared to try it because of all the negatives but then again i see a lot of positives too. Im just kinda stuck on what i should do does anyone have any suggestions?

Hi Helen. If your last baby went a week postdate I don't think your chances are extremely high, so up to you. Just make sure you take it correctly.

i am 40 weeks plus 3 days, i was scheduled for induction yesterday, but the hospital was full so now i have to wait until sunday. the reason for my doc wanting to induce baby so early is because he is so big and my first child being 10 lbs tore me so badly as i am a very petite size. i was in the hospital 6 days with my first and am very scared to go threw that again. friends and family are saying to try castor oil but i am nervous being im not that far past my due date and a lot i am reading says its not safe to do to early on, but im also nervous because the longer baby stays in me the bigger he will get. should i wait until sunday or give the castor oil a try?

Have PSD 4 years ago

I'm 38 weeks today, but I have PSD and I find it really hard to walk at times, turn over, etc. I took a tablespoon and it helped with me going to bathroom once and gave me nice contractions with a loss of mucous plug with a bloody show, but then they stopped. This was two days ago. I might try to take another tablespoon this morning and see if it takes me the rest of the way through. With my 4 year old 1 tablespoon worked and I didn't need any other medicine to induce and with my 9 year old it put me into labor, but the doctor was peeved at me and broke my water and gave me pitocin, so my contractions were horrible. I also have gestational diabetes so I get nervous going too far. He was 6 lbs 40z at the day I turned 36 weeks, so he is probably at least 7.5 now.

That is extremely dangerous and about six times the recommended dose for induction. I would recommend drinking a LOT of water and probably going to the hospital so they can keep an eye on you.

Dilation/effacement is no indication of impending labour - you can be 2cm dilated for weeks. As it's your first baby, you're less likely to go early anyway.

I would highly recommend that everyone DOES THEIR RESEARCH before taking random herbal or medical potions ESPECIALLY during pregnancy!

ProudToBeMommy 4 years ago

So Im 39 and some days..And my due date is July09,2012. Well Its my first child and I drank a whole 6oz bottle of castor oil at 8:00am this morning. Could I go into labor tonight or no?

I would really appreicate it if you could get back to me asap.

Thank You(:

WryLilt 4 years ago from Toowoomba, Australia Author

Thanks Mandi,

I would recommend waiting - first time mothers are 70% more likely to go postdate, so there is a good chance it won't work this early. You aren't overdue till 42 weeks. If you do try it, remember it will only work if your body is ready.

Two tips: giving birth on your back is the worst position as it closes the pelvis and I highly recommend having a look at delayed cord clamping to give your baby the best start to life.

Good luck!

mandi 4 years ago

I'm 39 weeks & 3 days along with my first child. I have been seeing my doctor weekly for the past several weeks and each week I hope for some progress, but only hear the same thing....that no progress is being made. My biggest concern is my boyfriend works away during the week and is only home late Thursdays - early Mondays. I convinced my doctor to schedule an induction for next Friday (2 days past my due date) when my boyfriend will be home. However, I've done a lot of research on castor oil and after reading this page, I'm highly considering trying that while my boyfriend is home this weekend, just in case she happens to come during the week before my induction. Besides, I'd rather not be medically induced. Hopefully you can get back to me with your opinion by tomorrow. If not, I think I will just go through with the oil tomorrow just to see if it works. Thanks for the advice in advance. And also for making this page. Best one I've seen yet informing women about castor oil induction

Kiyomi it will only work if the baby is ready.

And dilation/effacement can happen weeks before labour or not till labour starts. It is no indication of how soon it will be.

Hello. I read this guide and it helped me decide to try using castor oil to try to induce labor. I'm 39+4 weeks and the only reason I tried to take matters into my own hands is because I had my membranes stripped two days ago and nothing happened. Yesterday I mixed 2 tbsp of oil with oj, and it was mildly unpleasant. I didn't have abowel movement until this morning and it was only one. I decided to try it one more time, this time increasing the oil to 3 tbsp with the oj then I went outside for a walk. I just had a bowel movement after 6 hours, again only one. I'm not going to try again! That'd be stupid. It doesn't work for everyone. We'll see how the rest of the day goes. Ladies, your baby will come when it is ready to! You're crazy to try this before it's close to your due date.

41 weeks 1 day and am scheduled for an unwanted induction for Friday. I am going to give this a shot this morning and see what happens. My doula suggested 3 oz of castor oil in an orange juice and ice smoothie, but after reading here that seems like an excessive amount. I will start out small I think. Wish me luck!

Miranda I would wait. It sounds like you are having all the normal last month of pregnancy problems - dilation and effacement can begin weeks before and a mucous plug can regrow. It's in your baby's best interest to stay in as long as possible.

WryLilt 4 years ago from Toowoomba, Australia Author

Far too early! You can drop as early as 25 weeks and BH can start early in the first trimester. It's unlikely it would work - you'll just make yourself extremely uncomfortable. At least wait till 40 weeks if there are no complications - your baby will be healthier for the wait.

Hi, im 38 weeks n dialated 3cm i n have bin feeling contractions for a week already. I took castro oil yesterday at 4:30 pm and around 6pm i was vomiting. I started feeling contractions every 10 minutes after throwing up. Around 11:30 i went to bed an my husband rubbed my back to help with the pain. I fell asleep, n would walk up every so often when i would get a pain. I woke up a 6:30am and i haven't had any strong pains im a little lost! Should i take some more castro oil? I took 4 teaspoons the first time...

Carolyn 4 years ago

I took castor oil to induce the labour of my second child. It was her due date and my first birth was a fast 5 hours. My biggest concern was being stuck in a car or something and having my 19 month old deliver her sister (it would have been a great story though). I drank it at my toddlers bedtime 7pm, dealt with the inevitable trips to the washroom, for about 2 hrs, and sat on my birthing ball. I went to sleep about 10:30, cause I was bored by the Braxton hicks, and woke up half an hour later with a different contraction that I remembered from my first birth. At midnight, The hospital wouldn't admit me, cause I was only 1-2 cm. Good thing I didn't listen to them and stuck it out in the waiting room. She was born at 2:32am.

It worked for me, but I know of others that it hasn't worked for, even at 39 or 40 wks. I think it should be a last resort for someone who is just anxious to meet their baby.

Kaity 4 years ago

Just a heads up that the normal range of term is 38 to 42 weeks. So meaning if you go into labor at the end of 42 weeks, that is scientifically safe, healthy, and normal. I'm at 42 weeks or nearing 40 weeks (depending on which test results they are using) and plan to go 2 more weeks with no interventions. In my opinion, if the baby is not ready or fully developed, why force it to come out? (My midwife said that one of her 4 kids was born at 44 weeks, perfectly healthy. It happens more than we would imagine.)

WryLilt profile image

WryLilt 4 years ago from Toowoomba, Australia Author

Ash, it's unlikely that it will work at this early stage in pregnancy.

It only works if baby is almost ready to arrive (generally after 40 weeks).

Right now it will likely make you uncomfortable.

It can only hurt baby if you took a large dose (more than a tablespoon) or don't drink water (as it is a laxative, you need to make sure you stay hydrated.)

WryLilt profile image

WryLilt 4 years ago from Toowoomba, Australia Author

Unless your body is nearly ready to deliver, I don't think it will work that early.

It's possible to be effaced and dilated weeks before labour begins.

WryLilt profile image

WryLilt 4 years ago from Toowoomba, Australia Author

Hello Nearlythere,

It really depends on how the hospital plans to medically induce. If they are forced to use pitocin, which is the medical equivelant of oxytocin (the hormone that starts labour), you can have more severe contractions because the drug is being given at set intervals instead of being released naturally by your body.

Most natural induction methods are unlikely to give you labours that are any different to a normal one - since they usually just get labour going with a gentle nudge. Just remember that shorter labours are said to be more painful because your body is doing all that work in half the time.

This article on what to expect in a medical induction might be helpful if you're looking for further information about how your doctor will induce:

Nearlythere 4 years ago


I am 38+5 at the mo and trying to weigh up the options as to post date induction.. I have heard that when you are medically indced at the hosp you may have a much morw painful labour and atronger contractions.. Is this the same for natural induction auch as Castor Oil?!

Thanks in advance x

WryLilt profile image

WryLilt 4 years ago from Toowoomba, Australia Author

Anastacia I believe that you're trying far too early. As a natural induction method, castor oil will only work if you're near labour. All it will do if you're this early is simply make you very uncomfortable. I'd strongly recommend you sit back and wait - babies who go to 40 weeks have both a stronger chance of survival in the first year and are less likely to be born with complications.

Please don't take any more castor oil as it's obviously not working and will likely dehydrate you or cause other issues. Drink lots of water and wait another few weeks.

Anastacia 4 years ago

Anastacia 4 years ago

Four days ago, Saturday evening i had a table spoon of castor oil at about 8pm, at about 5:30 the next morning i had very bad cramps around my lower tummy and back, it felt as if baby was pushing down, i went into hospital at about 6 am as i was having three pains in 10mins, the mid wife however told me that the mouth of my womb hasn't opened and that i should return when the pains are stronger,she gave me some med to ease the pain. I got home at 8am and had another table spoon and went to bed, i haven't had any pain or effects since then, and its been 4 days. I'm 37 weeks and am in a lot of pain, i cant walk at times find it difficult to get up when im laying down, when my bladder is full sometimes not even its very pain full, when i was about 34 weeks i had a bladder infection but it has cleared and has not been back ever since. please advise as my mid wife has not been much help regarding

kierra 5 years ago

I have used castor oil to naturally induce all 6 of my labours and it has worked without fail every time, I found that i never really got the laxative effect so i was very lucky i think this was because i took it just before bed.i had no complications with any of their births and they were all happy healthy babies.I am currently pregnant with number 7 and will definitely be using this method again when i feel the time is right.

Maryn Leister 5 years ago

Good point to highlight that castor oil can increase the risk of dehydration. I'm not sure that a lot of moms know that. You see castor oil discussed all over the place as a way to get labor moving, but you really have to be careful about making sure you have enough fluids. Nobody needs a dehydrated laboring mama :)
