Castor Oil Packs: How to Make & Use Them (Step-by-Step)

A castor oil pack is a simple, old-fashioned remedy that people still swear by: a cloth soaked in castor oil, placed on the skin — usually over the tummy, liver area or an aching joint — often with gentle heat on top. Fans use packs for everything from dry skin and sluggish digestion to joint discomfort. In this guide we'll show you exactly how to make one, how to use it safely, and what the research actually says.

First: what is castor oil?

Castor oil is pressed from the seeds of the Ricinus communis plant — the "castor bean". Its main fatty acid, ricinoleic acid, is what gives the oil its moisturising, anti-inflammatory character. Quality matters here: for anything you put on your body, choose a cold-pressed, hexane-free castor oil — hexane is a solvent used in cheaper extraction, and naturopaths recommend avoiding it.

What are castor oil packs used for?

Skin comfort. This is where the evidence is strongest. Ricinoleic acid has soothing, anti-inflammatory properties that can calm redness, itching and irritation — think sunburn, bug bites and rash-prone skin — while the oil itself is a rich moisturiser that seals in hydration, softening dry, chapped skin and smoothing the look of fine lines.

Digestion & constipation. A small 2011 study in older adults found that using castor oil packs for three days didn't change how often participants went, but made bowel movements softer and easier, reducing constipation discomfort. Modest evidence, but it matches what many users report.

Joint comfort. Many people place a warmed pack over an aching knee, wrist or fingers. There's no clinical trial on packs specifically, but ricinoleic acid's anti-inflammatory action is the plausible reason so many arthritis sufferers find the ritual soothing.

The liver tradition. Natural practitioners have long recommended packs over the liver area to "support cleansing". We'll be straight with you: research hasn't confirmed this. It's a comforting traditional practice — enjoy it as one, without expecting a detox miracle.

How to make your own castor oil pack

You'll need:

1. Cold-pressed, hexane-free castor oil
2. Unbleached wool or cotton flannel
3. A medium bowl or container
4. Tongs and scissors
5. Plastic sheeting (a bin bag or small tablecloth works)

Directions:

1. Cut the flannel into rectangles of roughly 30 x 25 cm (smaller pieces for wrists or fingers).
2. Use three to four layers per pack.
3. Pour enough castor oil into the bowl to fully soak a piece of cloth.
4. Soak the first piece until saturated, lift it out with tongs (it should be dripping), and lay it flat on the plastic sheet.
5. Repeat with the remaining pieces, layering them on top of each other. That stack is your pack.

How to use it

1. Lie down on an old towel (castor oil stains!).
2. Place the pack on the area you're treating — over the stomach for digestion, on the joint for aches.
3. Cover with a small plastic sheet, and add a hot water bottle or heating pad on top if you like gentle warmth. Don't fall asleep with heat on — burns are real.
4. Relax for 45–60 minutes.
5. Remove and wipe the skin with a warm, damp cloth.
6. Store the pack in its soaking container in the fridge, covered — you can reuse it up to 30 times.

Safety first

• Patch test: rub a few drops of castor oil into your inner arm and wait 24 hours. No reaction? You're good to go.
• Skip packs if pregnant or breastfeeding — castor oil's effects on baby aren't established.
• Never microwave a pack — the oily cloth can smoke or catch fire.
• Not on broken skin — avoid fresh injuries, cuts or irritated areas.

Frequently asked questions

What do castor oil packs actually do?
The best-supported uses are soothing and moisturising the skin, easing constipation discomfort, and providing warm, comforting relief over stiff joints. Other traditional uses exist but lack research.

Do castor oil packs draw out toxins?
Honestly: there's no scientific evidence for the "detox" claim. Your liver detoxifies your body on its own — the pack is best enjoyed as a soothing ritual, not a cleanse.

How often can I use one?
Many users do 3–4 sessions a week; daily is fine for most people if your skin stays happy. Consistency over intensity.
