Bloating, cramping, breast tenderness, headaches and mood swings can arrive every month, disrupt your life for days and then disappear again until your next cycle. If you’ve been searching for a natural way to support PMS symptoms, there’s a good chance you’ve come across one of the biggest wellness trends right now — castor oil packs.
Castor oil packs are certainly not new. Castor oil has been used for thousands of years, and packs became popular in the United States in the early 1900s for everything from digestive complaints to pain. What is new is the enormous number of women turning to them for PMS, menstrual cramps and hormonal support.
So, do castor oil packs actually help with PMS?
They can be a useful support tool for inflammation, circulation and lymphatic flow, but they aren’t a miracle cure for PMS. How you use them, where you place them and what you’re doing to address the underlying hormonal picture all matter.
Why can PMS cause so much cramping and inflammation?
One important part of menstrual cramping is prostaglandins, hormone-like compounds your body produces around your period. Higher levels can contribute to the uterine contractions, inflammation and pain associated with menstrual cramps, but prostaglandins aren’t the entire story behind difficult PMS.
You also need to look at what is happening with your liver, estrogen, thyroid, iodine levels, gut health, histamine, stress and lymphatic flow. Constipation can add another problem because when everything is already feeling inflamed and congested through the lower abdominal area, poor elimination can make that discomfort feel even worse.
This is why I want you to stop looking at PMS as one isolated event that happens for a few days every month. The cramping, bloating, headaches and mood changes are symptoms, and those symptoms can give us valuable clues about what else is happening in the body.
What does your liver have to do with PMS?
Your liver helps process and clear hormones, including estrogen, but it also has an enormous number of other jobs to do every day. I like to think of your total load like a bathtub. When the bathtub is already filled right to the edge, continuing to pour more into it eventually causes it to overflow.
Think about everything you may be exposed to before you’ve even left the house in the morning. Skincare, makeup, deodorant, fragrances, hair products and plastics can all contribute to your overall chemical exposure. Some environmental chemicals can also have estrogen-like activity, which is one of the reasons reducing unnecessary exposure is an important part of my approach to hormonal health.
If your body is already struggling with its overall load, trying only to stop a menstrual cramp doesn’t address the bigger picture. Supporting the systems responsible for processing and clearing hormones becomes part of the conversation, and this is one reason castor oil packs have traditionally been used over the liver.
Could histamine be making your PMS worse?
Histamine is one of the areas I think many women completely overlook when they’re trying to understand why their PMS symptoms have become more intense.
Estrogen and histamine can influence one another. Estrogen can stimulate histamine release, while histamine can also influence estrogen activity. Around your cycle, this relationship can become another piece of the puzzle behind symptoms such as headaches, cramping and skin reactions.
Your overall histamine load also matters, which means looking at foods such as aged cheeses, cured meats, fermented foods, leftovers and alcohol. If your PMS symptoms have become much worse and you can’t understand why, histamine is worth considering as part of the wider picture.
What does your thyroid have to do with PMS?
Your thyroid is the master endocrine gland, which means thyroid health can have effects throughout your wider hormonal system. Iodine is also essential because your body needs it to produce the thyroid hormones T4 and T3.
At the same time, we are regularly exposed to other halogens, including bromine, chlorine and fluoride. These exposures are one of the reasons I place so much emphasis on iodine status when I work with people on thyroid and hormonal health.
Then we have chronic stress. Most women I speak to aren’t experiencing stress only when something terrible happens. They’re living with a high level of stress from the moment they wake up. Work, family responsibilities, financial pressure, notifications and deadlines can mean the nervous system rarely gets an opportunity to fully power down.
When you put thyroid health, iodine status, stress, estrogen, histamine, gut health, liver function and toxin exposure together, you begin to see why a bottle of castor oil can’t possibly be the complete answer to PMS. It can, however, be one useful part of the bigger picture.
How do castor oil packs work for PMS?
A castor oil pack is simple. Castor oil is applied to a cloth, the cloth is placed against the skin and heat is applied over the top.
Castor oil is unusually rich in ricinoleic acid, the fatty acid that gives the oil many of its distinctive properties. When castor oil is used topically with heat, the goal is to support the local tissues, circulation and lymphatic flow in the area where the pack is applied.
This is very different from drinking castor oil. Oral castor oil acts as a strong laxative, which is an entirely different use and is not what I am recommending when I talk about castor oil packs for PMS.
Where should you put a castor oil pack for PMS?
If your goal is broader hormonal support, I recommend placing the castor oil pack over your liver because your liver plays an important role in processing and clearing estrogen. This is the placement I use when we’re looking at the bigger hormonal picture rather than trying to address an immediate cramp.
If you are experiencing acute menstrual cramping, you can place the castor oil pack directly over the lower abdominal area where you’re experiencing the discomfort. You can therefore use castor oil over different areas depending on what you’re trying to support.
This is one of the biggest mistakes I see with castor oil packs. People hear that castor oil is good for PMS, put it somewhere on their abdomen once, don’t notice a dramatic change and decide it doesn’t work. Where you apply it, how you use it and how consistently you use it all matter.
Do you need heat with a castor oil pack?
Yes. I recommend using heat because it is part of the castor oil pack method and helps support local circulation and absorption. Putting a cold, oily cloth on your stomach isn’t the same thing as doing a proper castor oil pack.
I also recommend choosing a natural cloth rather than synthetic or heavily dyed material. If part of the reason you’re doing this is to reduce the burden of unnecessary chemical exposures, it makes very little sense to soak a synthetic or heavily dyed cloth in oil and hold it against your skin with heat.
Does the quality of castor oil matter?
If you’re going to apply an oil directly to your skin and leave it there with heat, I believe the quality of that oil matters enormously. This becomes even more important when reducing unnecessary chemical and toxin exposure is already part of what we’re trying to achieve.
Accelerated Scalar Castor Oil® is 100% pure, organic, non-GMO and cold pressed, with no chemicals, preservatives or fillers. Cold pressing means it is extracted without harsh solvents such as hexane that can be used in cheaper processing methods, and it then goes through a 10-micron filtration process. It is also scalar frequency enhanced.
You don’t want to spend time reducing your toxin exposure and supporting your liver only to apply a poor-quality oil to your skin, which is why I pay so much attention to the quality and processing of the castor oil itself.
Why combine castor oil with iodine?
My preferred method is to combine Accelerated Scalar Castor Oil® with Acceleradine® Iodine in a glass container until the mixture becomes a light-to-medium brown, then apply it topically to the area I’m targeting.
I use this combination because I don’t look at PMS purely as an inflammation problem. Iodine status and thyroid support are important parts of the hormonal picture, so combining the topical approach with iodine fits into the broader way I approach PMS support.
Topical iodine doesn’t replace supporting iodine status internally. The castor oil pack supports your body from the outside, while supporting your thyroid, iodine status, diet and other underlying factors works from the inside.
How often should you use a castor oil pack for PMS?
Consistency is one of the most important parts of using a castor oil pack. You can use a pack regularly, and I don’t recommend deciding whether castor oil works for you based on one application.
If you apply a pack once and don’t feel dramatically different the next day, that doesn’t tell you very much. We’re using it as a support tool for processes involving the liver, inflammation, circulation and lymphatic flow while also working on the factors contributing to PMS from the inside.
The aim isn’t to find one quick fix that makes every symptom disappear overnight. It is to consistently support your body while addressing why those symptoms are occurring.
Can a castor oil pack fix PMS on its own?
No. If you’re dealing with difficult PMS every month, I don’t want you to walk away thinking a bottle of oil is going to solve the entire problem.
Your thyroid health matters. Your iodine status matters. Your liver and gut matter. Stress, diet and your overall exposure to environmental chemicals matter too. If you’re ignoring all of those areas and expecting one topical treatment to compensate for them, you’re only addressing a small part of the picture.
Think about the castor oil pack as something you can do from the outside while supporting your body from the inside. When those approaches work together, you’re no longer just chasing the cramp. You’re beginning to ask why your body is experiencing so much inflammation and discomfort every month.
How can you best support PMS?
PMS isn’t something you should automatically dismiss as an unavoidable part of being a woman. If every month brings severe bloating, cramping, mood changes, headaches or other symptoms that interfere with your life, those symptoms are giving you information about what may be happening in your body.
A castor oil pack can be a useful way to support your body from the outside, particularly when used consistently, with heat and in the right location. At the same time, supporting your thyroid, iodine status, liver, gut, diet and stress response allows you to look at the hormonal picture from the inside.
Instead of asking only “How do I make this cramp go away?”, start asking “Why is my body struggling this much every month?”
That is where I would start.
PMS Castor Oil Pack FAQ’s
Castor oil packs can be used as a supportive tool for PMS, particularly when you’re looking to support local circulation, lymphatic flow and inflamed tissues. I don’t consider them a cure for PMS, and they work best as part of a broader approach that also considers thyroid health, iodine, liver function, gut health, stress, diet and toxin exposure.
For broader hormonal support, I recommend placing the pack over the liver area because of the liver’s role in processing and clearing estrogen. If you’re dealing with acute menstrual cramping, the pack can be placed over the lower abdominal area where you’re experiencing discomfort.
Yes. If menstrual cramping is your immediate concern, you can use the pack over the lower abdomen where you feel the cramping. This is different from placing it over the liver for broader hormonal and liver support, and the two locations can be used for different purposes.
Yes, I recommend using heat as part of the castor oil pack method because it supports local circulation and absorption. A heating pad can be placed over the pack while you’re using it.
Castor oil packs can be used regularly, and consistency is important. Using a pack once and expecting a dramatic change doesn’t give you a good indication of whether it can be a useful part of your routine.
Yes, although hormonal birth control changes your natural hormone production, so some of the processes involved in your cycle work differently. The broader areas we’re supporting, including liver clearance, inflammation and toxin load, can still be relevant whether or not you use hormonal birth control.
Castor oil packs can be used as a supportive practice if you have endometriosis or fibroids, but they shouldn’t be viewed as a treatment or cure for either condition. Significant menstrual pain, unusually heavy bleeding or symptoms that interfere with your daily life should also be medically evaluated.
Drinking castor oil isn’t the method I recommend for PMS. Oral castor oil acts as a strong laxative, while the PMS approach discussed here involves applying castor oil topically.
I combine Accelerated Scalar Castor Oil® with Acceleradine® Iodine because iodine and thyroid support are important parts of my wider approach to hormonal health. I mix them in a glass container until the mixture reaches a light-to-medium brown before applying it topically to the targeted area.
Using a castor oil pack once and expecting a miracle is one of the biggest mistakes. Putting it in the wrong place for what you’re trying to achieve or skipping the heat can also reduce the benefit. Use the liver area when your focus is hormonal and liver support, use the lower abdomen for acute menstrual cramping, include heat and stay consistent.
