Castor Oil – A Brief

Castor oil is the light yellow fluid that is separated from castor seeds (Ricinus communis). The Egyptians should be credited for perceiving its advantages and putting them to utilize.

Castor oil is utilized in beauty care products, meds, rub oils, and meds – given its strong helpful advantages. Around 90% of the oil is contained ricinoleic corrosive, which is its essential mending specialist (1).

How Can Castor Oil Cause Side Effects?

Castor oil is classified by the Food and Drug Administration (FDA) as generally recognized as safe (GRAS) and effective for use as a laxative. It is processed in the small intestine to release an active molecule called ricinoleic acid, along with other products (2).

Ricinoleic acid was suspected to be toxic to humans. But rat studies under the National Toxicology Program cleared it, stating that castor oil at concentrations up to 10% in the diet of rats was not toxic. A few human studies also produced concurrent results (2).

However, other animal trials with undiluted castor oil showed adverse effects. Ricinoleic acid, though not toxic by itself, may enhance the penetration of other chemicals through your skin. This may result in skin irritation and gut issues (2).

Here are some side effects you might want to watch out for.

What Are The Side Effects Of Castor Oil?

1. Nausea

Castor oil overdose can cause nausea. Though recovery is likely, not controlling the nauseating symptoms can lead to severe dehydration and electrolyte imbalance. This oil is also used as a preparation means for radiological and colonoscopy examinations (3), (4).

However, most patients fail to tolerate its aftertaste and oily texture. As per an Iranian study, castor oil-induced nausea can also be accompanied by vomiting, abdominal fullness, and cramps (4).

2. Skin Rashes

Animal studies found that castor oil was mildly irritating to the skin of the test subjects. Other allergic reactions to castor oil are redness (erythema) and hives. These can occur on the site where the oil is applied (5).

Castor oil is not a significant skin irritant or sensitizer in human clinical tests. But ricinoleic acid in it may aggravate the condition of patients with pre-existing skin conditions (2).

3. Muscle Cramps

This seed oil is a potent laxative. However, muscle weakness and cramps could result from a laxative overdose. It can also cause intestinal cramps and abdominal pain if taken on an empty stomach (6), (7).

This is why pregnant and menstruating women are advised against using castor oil as a laxative. It may also induce contractions of the womb (uterus) in some cases (7).

Hence, unless advised by your doctor, do not self-medicate with castor oil. The dosage is said to make all the difference, and it is best decided by a healthcare provider.

4. Dizziness

Dizziness is another symptom of castor oil overdose. Other castor oil side effects include fainting, shortness of breath, and, in rare cases, hallucinations (3).

Synthetic derivatives of castor oil are administered with other chemotherapy medications to manage breast, lung, ovarian, and skin cancer in patients. Inform the doctor if subjects experience hives, dizziness, difficulty in breathing, tiredness, chest pain, and/or irregular heartbeat (8).

However, the mechanism behind this effect is not established yet.

5. Lethal For Newborns And Children

In traditional Indian medicine, castor oil is given to infants 2-3 days after birth. This practice can result in severe intestinal damage, diarrhea, pneumonia, and malnutrition (9).

Consulting your doctor before taking such dangerous steps is recommended as there is insufficient literature about the safety of castor oil use in lactating women, new-mothers, breastfeeding infants, and children (9).

You may also be asked to consume castor oil supplements by your doctor, in a few cases. Castor oil supplements come in gelatinous capsules and are available only on prescription. They have similar side effects if you don’t stick to the clinically-set dosage (9).

However, you can prevent these side effects by taking the necessary precautions.

Side Effects Of Castor Oil Supplements

Castor oil supplements are usually in the form of gelatinous capsules. These capsules may have side effects if taken in excess. Though there is less research on the safety or toxicity of castor oil supplements, anecdotal evidence suggests that they carry the risk of higher levels of contamination.

Also, it is highly likely that castor oil supplements contain castor beans, which are highly toxic (27).

Other side effects of excessive consumption of the supplements could be similar to that of castor oil – abdominal cramps, nausea, diarrhea, etc.

Since their safety is not yet established, pregnant or lactating women should specifically avoid these supplements. Also, castor supplements containing other natural herbs may increase the risk of allergies.

Hence, consult your doctor before consuming castor oil or its supplements.

What Precautions Are Needed While Using Castor Oil?

  • Before you intake castor oil, you must first let your doctor know if you are allergic to plant oils.
  • Health conditions of the heart, brain, lungs, and vital organs must not be hidden from your healthcare provider.
  • Castor oil is not usually taken late in the day because its results occur within 2 to 6 hours.

The side effects may have largely to do with the dosing. What could be the ideal dosage?

What Is The Safe Dosage Of Using Castor Oil?

For adults and children over 12 years of age, 1-4 tablespoons maximum (15-60 mL) in a single daily dose may be safe (10).

For children of 2 to under 12 years of age, 1-3 teaspoons maximum (5-15 mL) in a single daily dose can be tried (10).

For children under 2 years of age, it is best not to give either castor oil or its supplements. Consult a doctor before taking the plunge (10).

In Summary

Castor oil is an excellent traditional remedy for GI tract, hair, and skin ailments. But since it has trouble-causing active molecules, its dosage has to be regulated.

Before you ingest or apply castor oil or any of its products, we urge you to discuss it with your healthcare provider. It is best to let them decide the safety and dosage for you.

Follow the instructions set by the doctors and stay vigilant to avoid side effects.
