Castor Oil Packs: Looking Honestly at the Ritual Everyone Is Posting

Castor oil packs have moved from obscure naturopathic practice to mainstream wellness ritual in about two years. The posts usually promise a great deal: better digestion, reduced bloating, hormone support, liver detoxification.

We sell castor oil. We are still going to tell you that most of those claims are not supported.

What a castor oil pack actually is

A cloth soaked in castor oil, placed on the abdomen, usually covered and warmed, and left on for 30 to 60 minutes. That is the whole practice. It is old - a staple of twentieth-century naturopathy - and it has resurfaced because it photographs well and requires nothing you cannot buy for ten dollars.

What the evidence supports

Being direct: there is very little clinical research on castor oil packs. Not conflicting research - almost none at all.

Castor oil taken orally is a well-established stimulant laxative, and that is genuinely documented. But that is a different thing from applying it to the skin. There is no good evidence that a topical pack detoxifies the liver, balances hormones or alters digestion through the skin.

"Detox" in particular is worth retiring. Your liver and kidneys handle that, continuously, and a cloth on your stomach does not assist them.

So why do people say it helps

Probably because of what the ritual actually involves, which is not nothing:

• Lying still for 45 minutes, which almost nobody otherwise does
• Gentle warmth on the abdomen, which is genuinely soothing for cramping and tension
• Slow breathing, because that is what happens when you lie down
• A deliberate pause at the end of the day

Those are real effects. They are just not the effects being advertised. If a nightly 45-minute warm, still, screen-free routine makes you feel better, it probably would with or without the oil - but the oil is what gets you to do it, and that is a legitimate reason to use it.

How to do it without ruining your sheets

1. Fold a piece of undyed cotton or wool flannel into a rectangle that covers your lower abdomen.
2. Saturate it with castor oil - damp through, not dripping.
3. Place on the skin, cover with an old towel, then a hot water bottle or heat pack on a low setting.
4. Rest 30 to 60 minutes.
5. Wipe the skin with a little baking soda in warm water.
6. Store the pack in a sealed glass jar in the fridge. It is reusable for a month or so.

Castor oil stains permanently. Use things you do not care about.

Who should not

Do not use during pregnancy or while trying to conceive without medical advice, on broken skin, or over any undiagnosed abdominal pain. Persistent digestive symptoms need a doctor, not a compress.

Our position

If you want a calming evening ritual and you like the feel of it, castor oil packs are harmless and cheap. If you are expecting detoxification or hormonal change, the evidence is not there, and we are not going to pretend otherwise.
