Castor oil, a vegetable oil derived from the seeds of the castor bean plant (Ricinus communis), has been used for thousands of years for various purposes, ranging from ancient Egyptian healing practices to a lubricant for wheels on carts and wagons. Today, it remains a popular remedy, with social media users touting its benefits for everything from weight loss to detoxifying the body. However, it is crucial to separate fact from fiction and understand the true potential-and limitations-of castor oil wraps.
What is a Castor Oil Wrap?
A castor oil wrap involves applying fabric soaked in castor oil to the skin. The idea is that placing soaked fabric on your skin will allow for better absorption than just massaging oil directly into the skin. Typically, unbleached cotton flannel is soaked in hexane-free castor oil and placed on the body, covered with a larger piece of fabric or plastic wrap, and sometimes a heating pad is added for better absorption.
How to Make and Use a Castor Oil Wrap at Home
Whether you opt to purchase a castor oil kit (easy to find online) or make one on your own, there are a few essential components:
- Castor oil (hexane-free)
- Unbleached cotton flannel, cut to fit areas of the body where you plan to use
- A large piece of cotton flannel or plastic wrap to cover and hold the pack in place
- Heating pad or hot water bottle (optional)
- Glass storage container for storing oil-soaked material when not in use
Making and using a pack includes:
- Soaking pieces of cotton flannel in castor oil
- Placing the soaked flannel on your body and cover with the larger piece of fabric or plastic wrap
- Putting a heating pad on top of the pack
- Relaxing for about an hour while the pack does its magic
- Removing the pack, storing it in the fridge in a glass container
- Cleaning the area that had the pack-castor oil can stain your clothes
A pack can be placed on:

Purported Benefits of Castor Oil Wraps
Castor oil used topically can:
- Help the liver to cleanse the body
- Reduce joint inflammation
- Ease digestion discomfort
- Aid in menstrual cycle pain
- Moisturize skin
Skin Benefits
Ricinoleic acid, a major component in castor oil, has analgesic properties, which may help soothe skin issues, such as:
- Sunburn
- Bug bites
- Allergic rashes
The castor oil’s anti-inflammatory effects may help reduce skin redness, puffiness, and itching. Additionally, castor oil is a good moisturizer and helps to seal in moisture. This can help heal dry, chapped skin and lips and plump fine lines and wrinkles.
Constipation Relief
People sometimes take castor oil by mouth as a laxative. In this way, castor oil is used to help bowel movements and empty the stomach. Using external castor oil packs may also help treat constipation.
A small 2011 medical study in Turkey tested the use of castor oil packs to treat severe constipation in older adults. The adults in the study used castor oil packs for 3 days. The researchers found that using the packs didn’t change the number of bowel movements, but it did make them easier to pass, softer, and reduced constipation symptoms. However, more research on the use of castor oil for constipation is needed.

Joint Pain Relief
Some people use warmed castor oil packs on the painful joint to help reduce inflammation and drain away blocked fluids that may cause more swelling. While there’s no specific clinical evidence for using castor oil packs in this way, the ricinoleic acid in castor oil may reduce inflammation and help soothe pain for many joint conditions, including rheumatoid arthritis. However, more specific research is needed.
Endometriosis
While there isn’t scientific research to support this use, it may be because the fatty acid ricinoleic acid may help soften masses and blockages and increase blood flow.
Liver and Gallbladder Health
Some natural practitioners recommend using a castor oil pack on the abdomen over the area of the liver. The idea is that the pack may help the liver move particles and cleanse the body. However, there is a lack of support for this theory. Medical research is needed to confirm using a castor oil pack for liver and gallbladder health.
Debunking the Myths and Misconceptions
Despite the numerous claims surrounding castor oil wraps, it's important to approach them with a critical eye. Many of the purported benefits lack scientific backing and are based on anecdotal evidence or traditional practices.
The "Detox" Myth
One of the most common claims is that castor oil wraps can "detox" the body. Detoxing refers to a variety of methods that claim to remove toxins from the body. Popular detox methods include juice cleanses and special diets. However, experts emphasize that the body has its own detoxification systems, primarily the liver and kidneys. There’s nothing that we’d recommend to use as a detox strategy beyond living a healthy lifestyle which can include eating well, exercising regularly and sleeping well.

Weight Loss Claims
Some social media users have suggested that applying castor oil compresses to the skin can help break up tumors inside the body. There is currently no research indicating castor oil as an effective aid to weight loss,” she says.
Navel Oiling
This idea is based on an Ayurvedic treatment that suggests a Pechoti gland near your navel can absorb things like essential oils through your belly button. But there’s no scientific evidence that this gland exists. So there's likely no advantage to putting castor oil in your belly button. But it probably won’t hurt you, either.
Castor Oil for Hair Growth
Castor oil is sometimes marketed as a treatment for dry scalp, hair growth, and dandruff. It may moisturize your scalp and hair. But there’s no science to back up claims that it treats dandruff or promotes hair growth.
In fact, using castor oil in your hair could cause a rare condition called felting, which is when your hair becomes so tangled that it has to be cut off.
Castor Oil for Eye Health
Rumor has it that Cleopatra used castor oil to brighten the whites of her eyes, a claim that has fueled some people’s belief that castor oil can contribute to healthier eyes. Proponents claim that it can do everything from improve eyesight to cure glaucoma.
None of these claims has any merit,” Dr. Hopkins states. “In fact, putting castor oil in your eyes can cause side effects like irritation, pain, blurred vision and even chemical burn-induced eye damage.”
Castor Oil as Lube
According to Women’s Health Interactive, it can be safe for some couples, but it’s not ideal for everybody.
Potential Risks and Side Effects
While castor oil wraps are generally considered safe for topical use, it's essential to be aware of potential risks and side effects.
- Allergic reactions: If you’re allergic to the castor plant, you may have itching, swelling, or rashes if you apply the oil to your skin. Test castor oil on a small spot before you use it.
- Acne and clogged pores: “Whenever there is an oil applied to the skin surface, there is a risk of clogged pores,” Mioduszewsk says. This can lead to acne or folliculitis - when your hair follicles become inflamed. You can also get an allergic reaction or dermatitis, she says, which will cause itchy bumps on your skin where you applied the oil.
- Pregnancy concerns: If you’re pregnant, avoid using it. It may induce labor. There isn't enough research to know whether castor oil is safe to use during pregnancy or breastfeeding. It’s not clear whether it’s safe for infants or children, either.
- Medication interactions: When you use castor oil for constipation, take it several hours before or after you take any other medications. Laxatives can change how other drugs work. Don’t combine it with any other laxatives or diuretics.
- Hallucinations: Hallucinations are one of the rarer potential side effects, but can be caused by swallowing a large amount of castor oil.
The Importance of Consulting a Healthcare Professional
Before incorporating castor oil wraps into your wellness routine, it is crucial to consult with a healthcare professional. They can help you determine if castor oil wraps are appropriate for your individual needs and health conditions, as well as advise you on proper usage and potential risks. For example, if you’re pregnant, breastfeeding or have some medical conditions, you should not use castor oil packs.
