Will Castor Oil Help Clear Up Your Actinic Keratosis?
Have you had a dermatologist examine the lumps and bumps on your skin? It is a good idea to have these checked periodically, especially if they have changed in any way. The doctor might diagnose some of the rough scaly patches on your skin as actinic keratoses. Could castor oil help clear them up? Some readers say yes.
Castor Oil and Baking Soda for Actinic Keratosis:
Q. I used castor oil mixed with baking soda to treat a prominent actinic keratosis that I’d had for years. It was gone after two days and hasn’t come back two years later. I can’t remember where I heard about this remedy, but others might want to know about it.
A. Actinic keratoses are pre-cancerous skin lesions. They are common on aging skin that has been exposed to ultraviolet radiation from the sun and may feel scaly or rough. Sometimes they itch or burn. A dermatologist should examine all such spots from time to time, as they could be an early form of skin cancer.
You are not the first person to report that castor oil could help an actinic keratosis, though other readers did not include the baking soda. We could not find any published studies of this remedy, but it seems benign. If it doesn’t work, the dermatologist can use a more standard approach such as freezing it off (cryotherapy) or applying a medicine like 5-fluorouracil (5-FU) cream, imiquimod (Aldara) cream or ingenol (Picato) gel.
Dermatologist Recommended Castor Oil for Actinic Keratosis:
Q. I thought you should know that years ago my husband’s dermatologist told him to use castor oil on pre-cancerous spots on his face. They all just sort of fell off and he never had to have any removed surgically.
A. We have to admit that we are surprised a dermatologist would actually recommend castor oil for pre-cancerous skin lesions. Most skin specialists would treat such a condition with standard approaches such as cryosurgery (freezing the abnormal cells) or topical medications. Some dermatologists opt for scraping (curettage) followed by cauterization (electrosurgery). Others use a laser to remove the abnormal cells.
Does Castor Oil Help Anything?
We searched the medical literature for research on castor oil against actinic keratosis, which is a skin lesion resulting from sun exposure. Such spots are often categorized as pre-cancerous changes that can turn into squamous cell carcinomas.
We found one reference to an article published in 1982 in the journal Acta Pathologica, Microbiologica, Immunologica Scandinavica suggesting that castor oil (Ricinus communis) binding to abnormal skin cells could be a useful diagnostic tool. A more recent study suggests that castor oil has both pro-inflammatory and anti-inflammatory activity (Current Drug Targets, Oct 1, 2011). We also found a reference suggesting that castor oil penetrates deep into the skin.
Despite this, we could find no credible evidence that castor oil can eliminate actinic keratoses. On the other hand, if a dermatologist were to supervise such treatment and follow a patient with these skin lesions carefully over time, the risk appears to be very low. If castor oil did not help the lesions, there are lots of approved treatments the dermatologist could fall back on.
Do You Have Actinic Keratosis?
If you have spent a lot of time out in the sun, there is a reasonable chance you do have actinic keratoses (AKs). How would you know? Do you have places on your skin that feel scaly or rough, a little like sandpaper? A dermatologist should examine anything on the skin that has a rough patch or that feels uncomfortable when rubbed. Notably, it could be an actinic keratosis. Itching or burning are other symptoms to bring to the attention of a physician. Some AKs feel wart-like and look like a bump.
Helen B. noted:
“This treatment has been around a long time. 65 years ago my mother had a pre-cancerous spot such as you are describing on her nose. Her doctor told her to rub castor oil on the spot daily for ten days and if it did not come off it would need to be burned off.”

This sounds very interesting, will try it.
I have used caster oil on the chest with bronchial coughing with little children who started coughing when lying down for the night and within about 2 minutes, they stopped coughing. I also tried it, and it worked like magic.
How best to apply and what proportion to mix for castor oil & baking soda?
We used castor oil on a large, flat skin tag on the sideburn area of my husband’s face. He’d previously had it removed by a doctor, but it had come back as large as before. He applied castor oil a couple times a day, and it went away completely and has not returned in nearly 10 years.
I’ll try it! I am a 63 year old Australian female, hence lots of sunspots. I am a retired podiatrist. I use urea cream, 20% on ‘stucco’ spots from sun on lower legs and feet, am reluctant to use on freckled face. But castor oil, no problems. Some people in Oz are trying bloodroot cream for their skin cancers. Some good, some indifferent results. Us Anglo Saxon Australians suffer the world’s highest rate of skin cancers, 45% of all skin cancers are on people of Irish and Scottish, i.e. Celtic descent (I’m just English, but reddish hair and freckles).
Greetings from Sydney, 20C in the middle of Winter.
Tried the castor oil with baking soda some months ago, recommended by a friend. Two unsightly ‘bumps’ raised areas on leg. Mixed the 2, applied and covered with bandage. It worked! I became concerned with terrible inflammation all around the site, thinking perhaps I did a dangerous thing. Learned I am allergic to latex, did not know, had no reason to check the band aid. Spots gone but the healing from the latex took months and has left [so far] permanent discoloration on skin. Beware latex.
A local eyebrow salon suggested castor oil on my eyelids to promote eyelash growth. Has anyone heard of this? I bought the oil but am now too wary to use it.
