Can You Drink Castor Oil? Benefits & Risks Explained
Yes, you can drink castor oil in small doses as a laxative, but consult a healthcare professional first due to potential side effects and dosage concerns.
Castor oil has been used for centuries as a natural remedy for constipation, skin care, and even wound healing. But is it safe to drink? This guide explores the science-backed benefits, potential risks, and best practices for using castor oil internally and externally.
What Is Castor Oil?
Castor oil is a vegetable oil extracted from the seeds of the Ricinus communis plant. The oil contains ricinoleic acid, a fatty acid responsible for its medicinal properties. Historically, it has been used in Ayurvedic medicine, ancient Egyptian remedies, and modern pharmaceuticals.
How Is Castor Oil Made?
The oil is extracted through cold-pressing or solvent extraction. A heating process deactivates ricin, a toxic enzyme, making the oil safe for consumption in small doses.
Is It Safe to Drink Castor Oil?
The FDA approves castor oil as a stimulant laxative, but only for short-term use. Drinking it can help relieve constipation but may cause side effects like:
- Abdominal cramping
- Bloating
- Nausea
- Diarrhea
How Much Castor Oil Can You Drink?
For constipation relief, adults can take 15-60 mL (1-4 tablespoons) orally. Start with a smaller dose to assess tolerance. Do not use it for more than 3-7 days without medical supervision.
Top Benefits of Castor Oil
1. Relieves Constipation
Castor oil stimulates intestinal muscles, speeding up bowel movements. A 2025 study found it increases bowel movement frequency by 19% compared to placebo.
2. Moisturizes Skin & Hair
Rich in fatty acids, castor oil locks in moisture. It’s often mixed with lemon juice or coconut oil for DIY skincare.
3. Supports Wound Healing
Its anti-inflammatory properties help treat wounds. Clinical ointments like Venelex combine castor oil with Peru balsam for wound care.
4. May Improve Eye Health
A 2025 study found castor oil reduces dry eye symptoms in people with blepharitis.
Risks & Side Effects
- Digestive distress: Overuse can lead to dehydration or electrolyte imbalance.
- Allergic reactions: Some people experience skin irritation when applied topically.
- Not for long-term use: Chronic laxative use can weaken bowel function.
Who Should Avoid Castor Oil?
Pregnant women (unless under medical supervision), children under 12, and people with bowel obstructions should avoid drinking castor oil.
How to Use Castor Oil Safely
For Constipation Relief
- Mix 1 tbsp with warm water or juice.
- Drink in the morning on an empty stomach.
- Expect results within 2-6 hours.
For Skin & Hair
Dilute with a carrier oil (like coconut or almond oil) before applying. For deep conditioning, mix with anti-inflammatory smoothie ingredients like turmeric for added benefits.
Final Thoughts
While castor oil has proven benefits, it should be used cautiously. Always consult a healthcare provider before using it internally, especially if you have digestive issues or chronic conditions.
