From the Guidelines
Castor oil packs are not a recommended treatment for digestive issues or menstrual cramps due to limited evidence and potential risks. When considering the management of digestive issues or menstrual cramps, it is essential to prioritize evidence-based treatments that have been proven to be safe and effective. According to a study published in Gut in 2020 1, castor oil can have a place in the treatment of constipation, but its principal effect is on small bowel fluid secretion, and it is rarely used due to potential side effects. The study also notes that dantron, cascara, and castor oil are rarely used, with dantron being potentially carcinogenic. In contrast, a more recent study published in Gastroenterology in 2024 1 provides best practice advice for managing constipation in pregnant persons, recommending dietary fiber, lactulose, and polyethylene glycol–based laxatives as treatment options. While castor oil packs may have been used in the past to manage digestive issues and menstrual cramps, the current evidence does not support their use as a primary treatment option. Instead, patients should focus on evidence-based treatments that have been proven to be safe and effective, such as dietary changes, laxatives, and other medications. It is also important to consult with a healthcare provider before starting any new treatment, especially if you have any underlying health conditions. Some key points to consider when managing digestive issues or menstrual cramps include:
- Dietary changes, such as increasing fiber intake and staying hydrated, can help promote regular bowel movements and prevent constipation 1
- Laxatives, such as lactulose and polyethylene glycol–based laxatives, can be effective in managing constipation 1
- Stimulant laxatives should be avoided due to conflicting safety data 1
- Patients should consult with a healthcare provider before starting any new treatment, especially if they have any underlying health conditions.
From the Research
Guidelines for Using Castor Oil Packs
- Castor oil packs have been used to manage digestive issues and menstrual cramps, with some studies suggesting their effectiveness in reducing symptoms of constipation and osteoarthritis 2, 3, 4.
- The use of castor oil packs involves applying a cloth soaked in castor oil to the affected area, which can help stimulate digestion and reduce inflammation.
- A study published in 2011 found that castor oil packs decreased the symptoms of constipation in elderly patients, including straining during defecation and feeling of complete evacuation after a bowel movement 4.
Safety and Efficacy of Castor Oil
- Castor oil is generally recognized as safe and effective for use as a stimulant laxative by the Food and Drug Administration (FDA) 2.
- The Joint Food and Agriculture Organization (FAO)/World Health Organization (WHO) Expert Committee on Food Additives has established an acceptable daily castor oil intake of 0 to 0.7 mg/kg body weight 2.
- A comparative clinical trial found that castor oil was as effective as diclofenac sodium in treating knee osteoarthritis, with fewer adverse effects reported 3.
Potential Uses and Benefits of Castor Oil
- Castor oil has been used to stimulate labor and has been shown to have anti-inflammatory and antimicrobial properties 2, 5.
- A systematic review of hair oils found that castor oil may improve hair quality by increasing hair luster, but there is limited evidence to support its use for hair growth or treatment of infestation 6.
- Castor oil is also used in the production of soaps, lubricants, and coatings, and is considered to be of important commercial value 5.
Precautions and Potential Side Effects
- Castor oil can cause skin irritation and allergic reactions in some individuals, and should be used with caution 2.
- High doses of castor oil can cause gastrointestinal side effects, including diarrhea and abdominal cramps 2.
- Pregnant women and individuals with certain medical conditions should consult with a healthcare professional before using castor oil packs or taking castor oil orally 2, 3.
