Castor oil has been part of home remedies for generations, but many people still don’t realise how versatile this thick, pale oil can be. From easing occasional constipation to caring for your scalp, castor oil quietly earns its place in many bathroom cabinets.
Here’s what this plant-based oil can do for you, and how to use it safely.
A traditional remedy still relevant today
Castor oil is made from the seeds of the Ricinus communis plant. It is high in ricinoleic acid, a fatty acid that may have anti-inflammatory properties. Across cultures, from Egypt to India, it has been used for skin, hair, and digestion.
Castor oil is a classic example of a traditional remedy that still has value. While it’s not a cure-all, it can support skin and hair hydration and help with occasional digestive issues when used appropriately.
It’s important to remember that castor oil is potent. It should be used carefully, especially internally, as too much can cause discomfort.
1. Supporting occasional constipation
Castor oil is well known for its laxative properties. In small, carefully measured doses, it stimulates the intestines and can help relieve occasional constipation. It’s important to note that it’s not intended for long-term use.
According to Harvard Health, castor oil can be effective but may cause cramping and urgency, so it’s best to use under guidance if you’re unsure.
Always follow label instructions, and consult a healthcare professional before using it internally, especially if you have gut sensitivities or are pregnant.
2. Moisturising dry skin
Castor oil’s thick, rich texture makes it excellent for sealing in moisture on dry or flaky skin. Many use it as an overnight treatment on heels, elbows, or hands.
The ricinoleic acid may also help reduce skin irritation and inflammation. However, castor oil can clog pores for some people, so always patch-test before applying to larger areas.
“Castor oil can create a protective layer on the skin, which helps prevent water loss,” explains Dr. Patel. “It can be helpful for people with dry skin, but use it sparingly to avoid clogging pores.”
3. Supporting hair and scalp care
Castor oil is a popular ingredient in DIY hair treatments. It can help moisturise a dry scalp, reduce flakiness, and add shine to hair.
To use it, warm a small amount between your hands, apply to your scalp and ends, leave for about 20 minutes, and wash thoroughly with shampoo. Because it’s thick, it can take a few washes to remove, so mixing it with lighter oils like jojoba can help.
While many people believe it can support hair growth, research is limited, but it remains a popular choice for adding shine and softness.
4. Soothing minor joint and muscle discomfort
Warm castor oil packs are sometimes used for minor aches and stiffness. People soak a cloth in warm castor oil, place it over the sore area, cover it with a towel, and add a heating pad for around 30 minutes.
Though scientific evidence is limited, some find the warmth and oil soothing. Always test the temperature carefully to avoid burns, and clean the skin afterwards to remove residue.
This simple home practice can be a gentle way to support comfort during periods of muscle tightness or joint discomfort.
5. Caring for eyebrows and eyelashes
A lesser-known use of castor oil is for conditioning eyebrows and eyelashes. Its thick consistency can help coat the hairs, keeping them moisturised and possibly reducing breakage.
Use a clean spoolie brush or cotton swab to apply a small amount to your brows or lashes at night, then wash off in the morning. While scientific evidence for hair growth is limited, many people find it helpful for keeping hair feeling soft and nourished.
“Castor oil can help protect hair from dryness, whether on your scalp or brows,” says Dr. Patel. “It’s a simple addition to your evening routine if you use it sparingly.”
Safety first
Castor oil can be a helpful natural remedy, but it’s not for everyone. Avoid using it internally during pregnancy unless guided by a doctor, and consult your healthcare provider if you have any medical conditions.
Always patch-test before using it on your skin, especially if you have sensitive skin, to avoid irritation.
Adding castor oil to your wellness toolkit
For those looking for natural, practical support for dry skin, hair care, minor aches, or occasional constipation, castor oil can be a versatile addition to your home wellness kit.
“Natural options like castor oil can play a role in self-care,” says Dr. Patel. “But remember, they should complement—not replace—medical care when needed.”
