People are rubbing oil on their stomachs and calling it a detox. It sounds weird. Honestly, if you’ve spent any time on TikTok or Instagram lately, you’ve probably seen influencers wrapping their midsections in wool flannel soaked in a thick, sticky liquid. They claim it fixes everything from bloating to hormonal imbalances. This is the castor oil body cleanse, an ancient practice that has suddenly become the internet’s favorite "hack" for gut health.
But does it actually do anything?
Castor oil comes from the Ricinus communis plant. It’s been around for thousands of years. The ancient Egyptians used it. Your grandma probably used it. It’s a triglyceride of fatty acids, with about 90% of those fatty acids being ricinoleic acid. That’s the "magic" ingredient. When people talk about a castor oil body cleanse, they are usually referring to two very different things: taking it orally as a laxative or using "packs" topically. We need to talk about the difference because one of them can send you to the bathroom in a panic, and the other is a bit more subtle.
Why a Castor Oil Body Cleanse is More Than Just a Laxative
Most people hear "cleanse" and immediately think of a bathroom emergency. It’s true. The FDA has cleared castor oil as a stimulant laxative. When you swallow it, an enzyme in your small intestine breaks it down into ricinoleic acid. This stuff binds to receptors on the smooth muscle cells of your intestinal walls. It makes them contract. Hard.
It’s not subtle.
However, the "cleanse" people are obsessed with right now usually involves castor oil packs. These are external. You soak a piece of organic cotton or wool flannel in the oil, place it over your liver (usually on the right side of your abdomen), and cover it with a heating pad. The idea is that the ricinoleic acid is absorbed through the skin. Proponents, including naturopaths like Dr. Marisol Teijeiro, suggest this stimulates the lymphatic system and supports the liver’s natural detoxification pathways without the violent digestive upset of drinking the stuff.
Does it work? Science is a bit thin here, but we do know that ricinoleic acid has proven anti-inflammatory properties. A study published in Mediators of Inflammation found that it acts similarly to capsaicin. It affects the "substance P" in our bodies, which plays a role in pain and inflammation. So, while it might not be literally "sucking toxins" out through your pores—the body doesn't really work that way—it might be calming down localized inflammation in the gut.

The Liver Connection and Lymphatic Drainage
Your liver is a beast. It’s the primary filtration system of the body. It converts toxins into waste products, cleans your blood, and metabolizes nutrients. Many people trying a castor oil body cleanse are looking to "support" the liver.
Basically, the theory is that the heat and the oil increase blood flow to the area. More blood flow means more efficient processing. There’s also the lymphatic system to consider. Unlike your heart, the lymphatic system doesn't have a pump. It relies on movement and pressure. By applying a pack, you’re potentially encouraging lymphatic circulation. Think of it like a very slow, oily massage for your internal organs.
It’s relaxng. Honestly, the 45 minutes you spend lying still with a warm pack on your stomach might be doing as much for your nervous system as the oil is doing for your liver. We live in a state of constant "fight or flight." When you switch to "rest and digest," your body can finally do the housekeeping it’s supposed to do.
What about the "Navel Pulling" Method?
You might have heard of putting castor oil in your belly button. It’s called the Pechoti method. Ayurveda, the traditional Indian system of medicine, suggests that the navel is a focal point for many nerves and veins. While there isn't a mountain of peer-reviewed clinical trials proving that three drops of oil in your belly button will cure PCOS or insomnia, many people swear by it for reducing menstrual cramps.
It’s low risk. It’s cheap. If it helps you sleep better because of a placebo effect or actual absorption, does it really matter which one it is? Just be careful with your sheets. This oil stains everything.
The Dangerous Side of the Cleanse
We have to be real here. You can’t just go chugging castor oil.

In the medical community, doctors generally advise against oral castor oil unless it’s a last resort for extreme constipation or used for medical prep. Why? Because it’s aggressive. It can cause severe cramping, vomiting, and electrolyte imbalances. If you’re pregnant, stay far away. Castor oil is historically known to induce labor by causing uterine contractions. You don't want to mess with that unless you're under the direct supervision of an OB-GYN.
Also, quality matters. A lot.
If you’re doing a castor oil body cleanse, you need "hexane-free," "cold-pressed," and "organic" oil. Hexane is a solvent used to extract oil from the seeds, and you definitely don't want that seeping into your skin. And please, use a glass bottle. Plastic bottles contain phthalates and BPA, which are endocrine disruptors. Since castor oil is a powerful solvent itself, it can actually leach those chemicals out of the plastic and carry them into your body. That kind of defeats the purpose of a "cleanse," doesn't it?
How to Actually Perform a Castor Oil Pack
If you’re going to do this, do it right. You’ll need a few specific items:
- Organic cold-pressed castor oil (in a glass bottle).
- A piece of organic cotton or wool flannel.
- Plastic wrap or a "wrap" kit (to prevent the oil from leaking).
- A hot water bottle or heating pad.
First, fold the flannel into a square that covers your upper right abdomen. Saturate it with the oil—it should be wet but not dripping. Place it on your skin. Wrap the area in plastic or a secondary cloth to protect your couch. Apply heat for 45 to 60 minutes.
Most practitioners suggest doing this three days in a row, then taking four days off. It’s not a one-and-done thing. It’s more of a ritual. You’ll notice your skin gets incredibly soft, and you might find that your bowel movements become more regular over the following days, even though you didn't drink the oil.

Misconceptions and Reality Checks
Let’s clear something up: your body doesn't have "layers of old toxic sludge" sitting in your colon that only castor oil can scrub away. That’s a marketing myth. Your body is actually very good at detoxing itself through the liver, kidneys, lungs, and skin.
A castor oil body cleanse isn't about "cleaning" you like a kitchen floor. It's about providing the conditions—reduced inflammation, increased blood flow, and nervous system relaxation—that allow your organs to do their jobs more effectively.
Some people claim they lose weight instantly. You’re not losing fat. If the scale moves, it’s because you’ve cleared out some water weight or backed-up waste. It’s a temporary shift. Don't look at this as a weight-loss tool. Look at it as a maintenance tool for your digestive health.
The "Herxheimer" Reaction
Sometimes people feel worse before they feel better. This is often called a "healing crisis" or a Herxheimer reaction. You might get a headache or feel a bit nauseous. While some claim this is "toxins leaving the body," it’s often just your body reacting to the shift in blood flow or even a slight reaction to the oil itself. Always do a patch test on your arm before you slather it over your liver. You do not want a full-body rash.
Actionable Steps for a Safe Experience
If you're curious about trying this, don't just jump in headfirst. Start small.
- Source the right oil: Look for the Heritage Store or Queen of the Throne brands. They are widely respected for being hexane-free and packaged in glass.
- Start with the navel: If a full pack feels too messy or intimidating, start by putting a few drops in your belly button at night.
- Stay hydrated: Any time you are working on your lymphatic system or digestion, you need water to move things along.
- Listen to your body: If you get a rash, stop. If you feel intense cramping, stop.
- Consult a pro: If you have gallbladder issues, kidney stones, or are pregnant, talk to a functional medicine doctor first.
The castor oil body cleanse is a fascinating bridge between ancient tradition and modern wellness. It isn't a miracle cure, but as a tool for managing inflammation and supporting digestion, it has more merit than your average viral trend. Just keep the oil off your favorite white t-shirt. Seriously. It will never come out.
