Castor oil is a plant-derived mild laxative.
After ingestion in the alkaline environment of the duodenum in the presence of bile, ricinoleic acid is formed from the oil under the influence of lipase.
The absorption of ricinoleic acid is inversely proportional to the size of the dose taken. With an administration of 4 g of oil, the absorption of ricinoleic acid is about 100%, with an administration of 50 g, only 36% is absorbed (the remaining acid is excreted with feces within 24 hours), and with an administration of 60 g, only 10% of the absorbed acid is present.

Composition
Castor oil (carrier), vitamin E (alpha-tocopheryl acetate).
Pharmacological action
Castor oil is a plant-derived mild laxative.
After ingestion in the alkaline environment of the duodenum in the presence of bile, ricinoleic acid is formed from the oil under the influence of lipase.
The absorption of ricinoleic acid is inversely proportional to the size of the dose taken. With an administration of 4 g of oil, the absorption of ricinoleic acid is about 100%, with an administration of 50 g, only 36% is absorbed (the remaining acid is excreted with feces within 24 hours), and with an administration of 60 g, only 10% of the absorbed acid is present.
The absorption rate of ricinoleic acid is half the rate of oleic acid absorption. To achieve a laxative effect, a minimum of 10 g of oil is necessary.
The absorbed portion of ricinoleic acid undergoes β-oxidation in the liver and skeletal muscles and is incorporated into metabolic processes.
Recommendations for use
As a laxative, adults are prescribed 15–30 g once a day. For bowel cleansing before diagnostic procedures, it is taken 2–6 hours before the examination. Children aged 12–14 are prescribed 5–15 g once a day.
In cases of weak labor contractions to stimulate labor activity, castor oil is prescribed at a single dose of 40–50 g against the background of using agents that stimulate uterine contractility.
In dermatological practice, for softening the skin and removing scales from areas of excessive keratosis, it is prescribed locally as a lotion on ethyl alcohol in a ratio of 1:10 with the addition of 2% salicylic acid (10 g castor oil, 2 g salicylic acid, ethyl alcohol up to 100 ml). The lotion is rubbed into the affected area once a day for 4–7 days, after which mechanical cleaning of the affected area is carried out, and treatment is continued.
For the treatment of burns and skin wounds, it is prescribed locally as lotions and emulsions on distilled water 1–2 times a day under a bandage.
To enhance hair growth, a solution is prepared consisting of 10 g of castor oil and 100 ml of 96% ethyl alcohol, which is rubbed into the scalp.
Side effects
Interaction
When used simultaneously, it reduces the absorption of fat-soluble vitamins A, D, and K. In doses up to 4 g/day, it increases the absorption of fat-soluble drugs - male fern extract, mebendazole, griseofulvin, probucol.
When used simultaneously with saline laxatives, a sharp increase in the laxative effect is possible.
M-cholinoblocking agents (atropine sulfate, platyphylline, pyrenzepine), spasmolytics (papaverine, drotaverine) weaken the action of castor oil.
Anticholinesterase agents (neostigmine, pyridostigmine, rivastigmine) and glycerin enhance the laxative action of castor oil.
It enhances the action of agents that stimulate uterine contractility (methylergometrine, ergometrine, oxytocin, prostaglandins) up to the threat of uterine rupture during childbirth.
When applied locally, it increases the transdermal absorption of drugs applied to the skin with it.

Mirrolla Castor Oil 50 ml is food-grade castor oil, a plant oil traditionally used when a short-term stimulating effect on bowel movement is needed. People usually choose this type of oil for occasional use rather than as a long-term digestive aid. In folk use, castor oil has also been known as a dense, emollient oil for skin and hair, which explains why it may appear in both food oil and cosmetic categories.
The main active part of castor oil is ricinoleic acid. It is not present in its free form in the bottle: after intake, digestive enzymes and bile help release it from the oil. In plain language, this fatty acid interacts with the intestine in a way that encourages movement of its contents forward. That is why castor oil is considered a stimulant laxative rather than a fiber source or a gentle bulking product. The formula also includes vitamin E in the form of alpha-tocopheryl acetate, which is commonly added to oil-based products for stability.
What makes castor oil different from many other edible oils is its unusual fatty acid profile and thick texture. It is much richer in ricinoleic acid than common kitchen oils, and that is what gives it its characteristic action. It is generally chosen for specific situations, for example when someone wants a one-time bowel-clearing option, not an everyday digestive routine. Because this effect depends on dose, castor oil is not the same as adding olive oil or flaxseed oil to meals.
This product may suit adults who already know this traditional oil and are looking for a food-grade version from Mirrolla. If you are considering it for internal use, it is best approached as an occasional measure. If your goal is regular digestion, many people are better matched with fiber, fluids, magnesium, or probiotic options depending on the situation.
Use castor oil thoughtfully: it is not meant for prolonged intake. Extra caution is sensible during pregnancy, while breastfeeding, for children, or if you have abdominal pain, nausea, intestinal sensitivity, or take medicines that affect fluid and mineral balance. If you are unsure whether a stimulant laxative is appropriate for you, ask a pharmacist or healthcare professional before use.
