Recently, spiritual guru Sadhguru sparked curiosity by recommending a traditional practice from Southern India: drinking half a spoon of warm castor oil mixed in water or milk every night. According to him, this keeps the colon clean and activates the lymphatic system. But is there any science behind this nightly ritual? We spoke to Edwina Raj, Head of Services, Clinical Nutrition & Dietetics at Aster CMI Hospital, Bangalore, to decode the facts.Castor Oil: Traditional Remedy or Gut Dependency?Castor oil has been used in Ayurvedic and traditional medicine for years as a natural remedy for constipation. But does that mean it’s safe or effective for daily use?“Castor oil is approved by the US Food and Drug Administration (FDA), as a stimulant laxative, and modern science sees it mainly as a short-term solution for constipation,” says Raj. She cautions that using it daily, even in small amounts, can lead to dependence. “Your gut may start relying on it to function, which could eventually disrupt natural digestion and bowel movements.”In essence, while it may help occasionally, frequent use might do more harm than good. “For long-term gut health, it’s better to focus on a high-fiber diet, adequate water intake, regular physical activity, and probiotic-rich foods.”Morning or Night? When’s the Right Time?Sadhguru suggested consuming castor oil at night, but nutrition experts aren’t fully convinced about the timing.“There is a lack of clinical evidence supporting the best time to take castor oil,” Raj notes. “Castor oil typically starts working within 2 to 6 hours, so taking it late in the evening could disturb your sleep.”She adds that consuming it right after a heavy meal could cause nausea or stomach discomfort. “It’s best taken occasionally and in small amounts, never self-administered regularly without expert advice,” she emphasizes.Can Everyone Digest Castor Oil? Not QuiteWhile some people may tolerate castor oil, not everyone’s digestive system can handle it smoothly.“People with IBS, ulcers, or other sensitive gut issues may experience cramping, bloating, nausea, or diarrhea,” Raj warns. “It stimulates the intestines, which can be harsh for vulnerable digestive systems.”What’s more, castor oil is derived from Ricinus communis, a plant that contains a toxic compound called ricin. “Although ricin is mostly removed during oil processing, the plant’s laxative effect can interfere with absorption of other medications,” she adds.Pregnant women should also avoid it. “Castor oil may induce premature labor contractions and is not recommended for those with inflammatory bowel conditions like Crohn’s or colitis.”Beyond a Laxative: Are There Other Benefits?Ayurveda often promotes castor oil as a multi-functional remedy, but what does modern science say?“Ricinoleic acid in castor oil does have anti-inflammatory and antimicrobial properties,” Raj explains. “But these are primarily beneficial when used externally, such as in castor oil packs for skin or joint pain.”When ingested, especially on a regular basis, the risks may outweigh the benefits. “There is limited scientific evidence supporting long-term internal use of castor oil for general wellness.” So while ancient wisdom gives it a prominent role, it must be used with caution in modern-day routines.Is It Safe to Consume Castor Oil Long-Term?This is where things get tricky. While some believe a small daily dose is harmless, experts are wary.“Long-term use, even in small doses, can lead to dependency, electrolyte imbalance, and nutrient malabsorption,” Raj warns. Diarrhea from overuse can deplete vital minerals like potassium and magnesium, leading to fatigue, dizziness, and dehydration.She adds, “The gut may lose its natural motility, and your body may struggle to process nutrients efficiently. This could have serious consequences over time.”Use Occasionally, and With Guidance]]>While Sadhguru’s recommendation draws from age-old traditions, it’s crucial to differentiate between cultural practices and evidence-based health strategies.“Castor oil should be used as an occasional remedy, not a daily habit,” Raj concludes. “Always consult a doctor or nutritionist before adding it to your routine, especially if you have underlying conditions.”In short, if you’re seeking better gut health, your best bet still lies in fiber, hydration, movement, and mindful eating—not in relying on nightly shots of castor oil.Disclaimer: This article is intended for informational purposes only and should not be considered medical advice.
