Key takeaways

  • Ginger has strong scientific evidence for easing morning sickness and is endorsed by major obstetric guidelines — it's the standout Ayurvedic remedy that is genuinely safe in pregnancy.
  • Avoid oral aloe vera, senna, and castor oil — all can stimulate the uterus or cause harm — and avoid all bhasma (calcined metal) preparations, which may contain mercury, lead, or arsenic.
  • ‘Natural’ does not mean ‘safe’ in pregnancy. Culinary amounts of common spices are usually fine; concentrated supplement doses often are not.
  • Garbhini Paricharya's core advice — rest, dietary variety, gentle movement, stress reduction — broadly matches modern pregnancy wellness guidance.
  • Tell your obstetrician about every Ayurvedic medicine, tonic, and herbal tea you use. Undisclosed remedies are the biggest avoidable risk.
  • Choose a registered BAMS practitioner, not a lay vaidya, and use products only from reputable, quality-controlled manufacturers.

Garbhini Paricharya: the Ayurvedic framework for pregnancy

Garbhini Paricharya means ‘regimen for the pregnant woman’ (garbhini = pregnant woman, paricharya = care). Described in classical texts such as the Charaka Samhita and Sushruta Samhita, it lays out month-by-month (masanumasika) advice on diet, lifestyle, and herbs from conception through delivery and the postpartum period (sutika paricharya).

The framework rests on Ayurveda's tridosha theory — vata, pitta and kapha — and treats pregnancy as a time of natural shifts in this balance, with vata thought to rise in late pregnancy and labour. The month-by-month guidance broadly moves from rest and sweet, easily digestible foods (milk, ghee, cooked grains, fruit) in early pregnancy toward gentle oil applications and labour preparation later on.

Across all the months, a few principles repeat:

  • Eat fresh, freshly cooked, varied meals covering all six tastes (shadrasa).
  • Avoid alcohol, fermented and leftover foods, and very hot or cold extremes.
  • Get adequate rest — daytime sleep is specifically allowed in pregnancy.
  • Avoid heavy lifting, strenuous activity, and long, jolting travel.
  • Protect emotional wellbeing; avoid anger, grief and stress.
  • Don't suppress natural urges (urination, bowel movement, hunger, sleep).
  • Avoid harsh detox procedures, strong purgatives and bloodletting.

Much of this maps neatly onto modern advice. Dietary variety, rest, stress reduction, gentle movement, and avoiding alcohol and risky foods are all things your obstetrician would endorse, and a balanced Indian thali already delivers most of the ‘six tastes’ idea.

A few specifics need a second look. Oil enemas (anuvasana basti) and vaginal oleation (yoni pichu), recommended in some centres in the ninth month, are not used in modern obstetrics because of infection risk and unclear benefit. Some food taboos (around papaya, pineapple or certain ‘hot’ foods) overlap with cultural beliefs that have limited evidence. The sensible approach is to embrace the lifestyle wisdom freely and to run any specific procedure or medicine past your antenatal provider first.

AYUSH, BAMS and how Ayurveda is regulated in India

The Ministry of AYUSH (Ayurveda, Yoga and Naturopathy, Unani, Siddha and Homeopathy), made a full ministry in 2014, oversees traditional Indian medicine. It sets education standards through the National Commission for Indian System of Medicine (NCISM, formerly the Central Council of Indian Medicine), funds research via the Central Council for Research in Ayurvedic Sciences (CCRAS), and runs flagship institutions such as the All India Institute of Ayurveda (AIIA, Delhi) and the National Institute of Ayurveda (NIA, Jaipur).

Who is qualified. A genuine Ayurvedic doctor holds a BAMS (Bachelor of Ayurvedic Medicine and Surgery), a 5.5-year degree including internship, and is registered with a state medical council. Some hold a postgraduate MD/MS, including in Prasuti Tantra evam Stree Roga (the Ayurvedic equivalent of obstetrics and gynaecology). You can verify a practitioner's registration on your state Ayurvedic medicine council's website. Self-styled ‘vaidyas’, gurus and family advisers without formal training carry no such accountability — quality and safety are unpredictable.

How medicines are regulated. Ayurvedic medicines fall under the Drugs and Cosmetics Act, with Schedule T setting good-manufacturing-practice standards. In practice, quality varies enormously. Products from established companies (Dabur, Himalaya, Baidyanath, Kerala Ayurveda, AVP and similar) generally have tighter quality control than small, unbranded preparations. Independent testing has documented heavy-metal contamination, microbial contamination, and even adulteration with allopathic drugs in some products — most worryingly in bhasmas (covered below).

AYUSH services are increasingly available alongside allopathic care in district hospitals and some tertiary centres, and AYUSH treatment is covered under several state and PMJAY schemes at empanelled facilities. But real limitations remain: inconsistent enforcement of practitioner registration, variable medicine quality, a thin evidence base for many practices, and frequent communication gaps where patients use both systems without either provider knowing. The practical takeaway is simple — use a registered BAMS practitioner, choose quality-assured products, and keep your obstetrician informed.

Ayurvedic herbs that are safe in pregnancy

Several Ayurvedic herbs and dietary staples are genuinely safe in pregnancy, and one — ginger — has strong scientific backing.

Ginger (Zingiber officinale; Ardraka/Shunthi) is the standout. Multiple randomised trials and Cochrane reviews show it reduces nausea and vomiting in pregnancy, with efficacy comparable to vitamin B6. The American College of Obstetricians and Gynecologists (ACOG) lists it as a first-line non-drug option for morning sickness. Practical dosing:

  • 250–500 mg of dried ginger powder, 3–4 times a day, or
  • fresh ginger tea (ginger slices in hot water with honey/lemon), or
  • ginger candies or lozenges.

Keep the total below about 4 g a day, and check with your doctor before using more than 2 g daily for long stretches. Ginger is available everywhere in India — fresh from any vegetable market, or as Shunthi powder — for roughly Rs 20–100 a week. Our morning sickness relief guide for India goes into more detail.

Common culinary spices are generally safe at normal cooking amounts — the key phrase being culinary amounts, not concentrated supplements:
  • Cardamom (Ela), coriander (Dhanyaka), cumin (Jiraka), fennel (saunf) — used in everyday Indian cooking and to settle digestion; fine in food quantities.
  • Turmeric (Haridra) — safe as the spice in cooking and in haldi doodh. Avoid concentrated curcumin supplements, which aren't well studied in pregnancy.
  • Tulsi (holy basil) — fine as tea or in cooking; avoid concentrated extracts.
  • Amla (Indian gooseberry) — a good vitamin C source as fruit or juice.

One traditional recommendation to set aside: yashtimadhu (licorice, Glycyrrhiza glabra). Although it appears in classical Garbhini Paricharya, modern evidence links higher-dose licorice to preterm birth, high blood pressure and low potassium. The WHO and other authorities advise avoiding it in pregnancy beyond trace culinary amounts. It's a clear example of where long tradition and modern safety data part ways.

The principle running through all of this: prefer well-studied foods at normal dietary amounts, be cautious with concentrated supplements, and discuss anything specific with your obstetrician.

Ayurvedic herbs and preparations to avoid in pregnancy

Some Ayurvedic and folk preparations carry real risks in pregnancy. The main concerns are herbs that stimulate the uterus (risking cramping, bleeding, miscarriage or premature labour), herbs with hormonal effects, and anything containing heavy metals.

Avoid these:

  • Oral aloe vera (Kumari) — the latex contains strong purgatives that can stimulate the uterus and cause cramping or bleeding. Many women take aloe juice for ‘detox’ or constipation; stop in pregnancy. Topical aloe gel on skin is fine.
  • Senna (Swarnapatri) — a powerful laxative with uterine-stimulant effect. Check labels: many commercial ‘digestive’ and laxative products contain it.
  • Castor oil — sometimes used to ‘bring on labour’. Strongly discouraged in modern obstetrics: it causes distressing diarrhoea, dehydration and meconium passage without reliably starting labour.
  • Pippali (long pepper) and chitraka (Plumbago zeylanica) — uterine stimulants.
  • Ashwagandha and brahmi — popular supplements with limited pregnancy safety data; generally best avoided unless an experienced provider advises otherwise.
  • Shatavari — marketed for women's health but with a thin evidence base and phytoestrogen concerns; not recommended routinely in pregnancy.
  • Triphala — the haritaki component has a purgative, uterine-stimulant effect; avoid or minimise.
  • ‘Menstrual regulator’ preparations — by definition these promote menstruation, so they are inherently unsafe in pregnancy. If you used one before conceiving, stop now.
  • Concentrated fenugreek (methi) supplements — methi in normal cooking is fine, but high-dose capsules (used for diabetes or lactation) can stimulate uterine activity; avoid in pregnancy.
  • Most essential oils — use only pregnancy-safe options in any massage or aromatherapy.

Watch for drug–herb interactions with your prescribed medicines. Some herbs lower blood sugar (relevant if you have gestational diabetes), some affect the thyroid (relevant if you take medication for thyroid changes in pregnancy), and a few have antiplatelet effects that increase bleeding risk. This is exactly why full disclosure to your obstetrician matters.

Safer alternatives for constipation — a common reason women reach for risky laxatives — include psyllium husk (Isabgol), more dietary fibre, plenty of water, gentle walking, and stewed prunes; lactulose can be used if needed under medical advice. Our constipation and bloating in pregnancy guide covers this fully.

The reassuring part: the herbs of concern are well defined and easy to avoid once you know them. When in doubt, stick to culinary amounts of familiar spices and skip concentrated supplements you don't truly need.

Bhasmas and heavy-metal concerns

Bhasmas are calcined ash preparations made from metals or minerals — part of the Rasashastra tradition. Common ones include lauha bhasma (iron), praval bhasma (coral calcium), swarna bhasma (gold), tamra bhasma (copper), and classical preparations containing mercury (hingula) or arsenic (manashila).

Traditional theory holds that elaborate purification (shodhana) and trituration (bhavana) transform raw metals into safe, therapeutic forms. The modern safety concern is that independent chemical testing often finds substantial residual heavy metals — mercury, lead, arsenic and cadmium — in some bhasma products, and there are documented case reports of heavy-metal poisoning, including lead poisoning in children, attributed to such medicines.

Why this matters so much in pregnancy:

  • Mercury, lead and arsenic are established teratogens and developmental toxins — they can harm the developing fetal nervous system.
  • The placenta does not block heavy metals; they cross to the baby.
  • Even ‘small amounts’ can accumulate with chronic use, and the fetus is especially vulnerable.

The clear recommendation: avoid all bhasma preparations during pregnancy, whatever the claimed benefit — fertility, strength, energy, immunity or otherwise. This is one area where modern evidence and traditional practice genuinely diverge, and the precautionary principle wins. Read labels carefully for terms like rasa or bhasma, and ask your Ayurvedic provider directly whether any prescribed preparation contains metals. Be especially wary of unlabelled ‘tonics’ and rasayanas (rejuvenatives).

For nutritional needs, use pharmaceutical-grade supplements with known purity and standardised dosing rather than bhasma forms — standard ferrous iron salts for iron, and calcium carbonate or citrate for calcium, not lauha or praval bhasma. The right pregnancy supplements and doses are best set by your antenatal team.

If you've already taken bhasma during pregnancy, don't panic — stop it, and tell both your Ayurvedic and allopathic providers exactly what it was. Heavy-metal blood testing (lead, mercury) can be arranged if exposure is a concern (typically Rs 1,500–5,000 per test), with growth scans and surveillance guided by the results. Most women with brief, low-dose exposure go on to have healthy pregnancies; sustained high-dose use is the bigger worry.

Ayurvedic lifestyle practices: yoga, massage and diet

Beyond medicines, much of Ayurveda is lifestyle — and here most practices are safe and beneficial.

Yoga in pregnancy is widely recommended for fitness, flexibility, breath control, better sleep, stress relief and labour preparation. Pregnancy-safe poses include pelvic tilts, cat-cow, gentle hip openers, supported child's pose, and chair yoga. Important modifications:

  • Avoid lying flat on your back after 20 weeks.
  • Avoid prone (face-down) positions after the first trimester.
  • Avoid deep twists, inversions, intense abdominal/core work, and hot (Bikram) yoga.
  • For breathwork (pranayama), favour gentle deep breathing and alternate-nostril breathing; avoid forceful, rapid techniques and long breath holds.

Practise with a qualified prenatal yoga teacher where possible, and stop and call your provider for any bleeding, contractions, severe pain or dizziness. Our yoga for pregnancy in India guide has safe sequences.

Abhyanga (oil massage), especially in the third trimester, is part of Garbhini Paricharya and is generally safe with sensible precautions: use gentle pressure (not deep tissue), pregnancy-safe oils such as sesame, coconut or olive oil, lukewarm (not hot) oil, and a side-lying position later in pregnancy. Avoid deep abdominal massage in the first trimester, and skip it if you have a condition like preeclampsia (high blood pressure) without your provider's approval. See safe pregnancy massage in India.

Ayurvedic dietary practice — fresh, freshly cooked, varied meals across the six tastes, mindful eating, and good hydration — aligns well with modern pregnancy nutrition. Curd and yogurt are fine and beneficial despite traditional caution about fermented foods. A few specifics (avoiding papaya or pineapple as ‘hot’ foods) are cultural beliefs with limited evidence — discuss them with your provider rather than restricting your diet unnecessarily.

Practices to avoid in pregnancy: Panchakarma detox therapies (therapeutic vomiting, purgation, bloodletting), oil enemas (anuvasana basti) and vaginal oleation (yoni pichu). Classical Ayurveda itself contraindicates the harsh detox procedures in pregnancy, and the enema/vaginal procedures carry infection risk without clear benefit.

Postnatal Ayurvedic care (sutika paricharya) — a rest period, warming nourishing foods and gentle oil massage — largely matches modern postpartum recovery advice. Just apply the same caution to herbs and bhasmas while breastfeeding, since substances pass into breast milk.

Combining Ayurveda with your antenatal care

Most Indian women use allopathic care for the backbone of pregnancy — scans, blood tests, BP checks, screening and delivery — while drawing on Ayurveda for symptoms and wellbeing. That works well, if the two systems can see each other. Too often a communication gap means neither provider knows the full picture.

Disclose everything. Your obstetrician needs to know every prescription medicine, over-the-counter remedy, Ayurvedic medicine, herbal tea, tonic and supplement you take — including things that feel like ‘just food’, such as turmeric capsules. Without this, they can't spot drug–herb interactions or contraindicated ingredients. A simple habit: bring a written list (or the actual containers) to each antenatal visit, and update it whenever something changes.

Talk to your Ayurvedic practitioner too. Confirm they are a registered BAMS doctor, tell them you're pregnant and how many weeks, list your allopathic medicines, and ask directly whether any recommended preparation is pregnancy-safe and whether it contains bhasmas or metals. Get recommendations in writing.

A simple decision framework:

  • Diet and lifestyle (more vegetables, variety, hydration, gentle yoga, rest, meditation) — generally safe; adopt freely.
  • Culinary spices in cooking amounts — fine.
  • Ginger for nausea — evidence-based and safe; discuss dose if using concentrated forms.
  • Any ingested Ayurvedic medicine or formulation — clear it with both providers before starting.
  • Procedures (Panchakarma, basti), bhasmas, and known uterine-stimulant herbs — avoid.

Some things belong firmly with modern medicine and should never be replaced by Ayurveda alone: routine antenatal screening and monitoring; management of high-risk conditions such as Preeclampsia in Pregnancy: High BP, Warning Signs and Care, gestational diabetes and anaemia; pregnancy vaccines (don't swap an immunity tonic for a vaccine); decisions about labour induction and mode of delivery; and any emergency. Ayurveda can complement — through diet, gentle movement, massage, stress management and mild symptom relief — but it can't substitute for these.

The bottom line: take what's safe and helpful from each system, keep both providers informed, and let safety lead whenever the two disagree.

Choosing a practitioner and quality products

Quality varies hugely across Ayurvedic care in India, so choosing well is central to staying safe in pregnancy.

For a practitioner, look for a registered BAMS doctor — ideally with a postgraduate qualification in Prasuti Tantra evam Stree Roga (obstetrics and gynaecology) for pregnancy care — practising at a recognised Ayurveda hospital, an AYUSH wing of a major hospital, or an established clinic. Verify registration on your state Ayurvedic medicine council's website. Avoid lay practitioners and self-styled vaidyas without verifiable credentials, advice from family or friends presented as treatment, unverifiable online consultations, and shopkeepers in Ayurvedic stores who are selling rather than examining you.

For products, prefer reputable manufacturers with GMP certification and AYUSH approval (Dabur, Himalaya, Baidyanath, Kerala Ayurveda, AVP and similar). Avoid unbranded products, anything without a full ingredient label, and products with unverifiable claims. In pregnancy specifically:

  • Read the full ingredient list and check for bhasmas, mercury (hingula, parad), arsenic (manashila), and lead-containing materials.
  • Check for contraindicated herbs (aloe, senna, castor-oil-based products).
  • Prefer single-ingredient products over complex classical formulations whose contents are hard to verify.

Common, avoidable mistakes:
  • Self-medicating with Ayurvedic products without consulting anyone.
  • Continuing pre-pregnancy tonics (chyavanprash, ashwagandha) without checking pregnancy safety.
  • Assuming ‘natural’ means ‘safe’.
  • Using Ayurvedic remedies to replace prescribed medicines, or to delay seeking care for worrying symptoms.
  • Not disclosing Ayurvedic use to the obstetrician.

Red flags that signal unsafe practice: no verifiable credentials; recommendations without proper history or examination; promises of ‘miracle cures’ or guaranteed outcomes; secret or ‘special’ formulas; lack of ingredient transparency; pressure to buy expensive products; being discouraged from seeing your obstetrician or from disclosing Ayurvedic use; or any recommendation of aloe, senna, castor oil or bhasma despite your pregnancy. If you encounter these, walk away and find a qualified provider. For genuine expert input, institutions such as AIIA (Delhi), NIA (Jaipur) and major Ayurveda hospitals offer credible consultation.

Ayurveda for common pregnancy complaints

Here's the integrated, evidence-based approach for the issues women most often turn to Ayurveda for.

Morning sickness. Ginger (250–500 mg dried, 3–4 times daily, or fresh ginger tea or candies) has strong evidence; vitamin B6 (pyridoxine) 25 mg three times daily helps too. Eat small, frequent meals, avoid strong-smelling and fatty triggers, and try mint or cardamom. If vomiting is severe (hyperemesis gravidarum), you need medical care — anti-nausea medication, IV fluids, sometimes admission.

Constipation. More fibre, 2–3 litres of water, gentle walking, psyllium husk (Isabgol), stewed prunes and curd all help. Lactulose is safe if needed. Avoid senna, aloe juice and castor oil.

Sleep difficulties. Good sleep hygiene, gentle yoga, alternate-nostril breathing, a pregnancy pillow for side-sleeping, and limiting caffeine after lunch. Avoid brahmi and sleeping pills unless prescribed. Persistent severe insomnia deserves evaluation — see pregnancy insomnia relief.

Energy and fatigue. The commonest cause in Indian pregnancies is anaemia. Eat iron-rich foods (leafy greens, dal, jaggery, dates, nuts) and take prescribed iron — standard pharmaceutical iron, not lauha bhasma. Thyroid problems also contribute. Avoid ashwagandha supplements and bhasma-containing ‘strength tonics’. See anaemia in pregnancy.

Anxiety and stress. Counselling, mindfulness, gentle yoga, pranayama, good sleep and social support all help. For clinical anxiety or depression, seek professional mental-health care — some antidepressants are pregnancy-safe and talk therapy works well. Helplines: iCall 9152987821, Vandrevala 1860-2662-345. Don't use herbs for anxiety in pregnancy without provider guidance. More in pregnancy anxiety vs depression.

Cold and flu. Rest, fluids, steam inhalation, honey-lemon in warm water, and moderate tulsi tea are fine. Avoid OTC cold remedies (many contain pseudoephedrine) without approval, and skip concentrated immunity tonics that may hide bhasmas. The flu vaccine is recommended in pregnancy. See a doctor for fever above 100.4°F lasting over 24 hours or any breathing difficulty.

Postpartum hair loss. Common and usually self-resolving over 6–12 months. Good nutrition and gentle scalp oil massage help; avoid herbal hair tonics of uncertain content.

Postnatal recovery. A rest period, warm cooked foods, and sesame-oil massage are generally safe and supportive. Avoid bhasma-containing ‘strength tonics’ while breastfeeding, and seek proper mental-health care for postpartum depression rather than relying on Ayurveda alone.

What the evidence does and doesn't show

It helps to know where the science is solid and where it's thin.

Strong evidence supports: ginger for nausea (multiple trials, ACOG-endorsed); dietary variety and balanced nutrition; adapted pregnancy yoga for stress, sleep and labour preparation; adequate rest and stress reduction; avoiding alcohol and risky foods; and gentle oil massage for relaxation.

Strong evidence is against using oral aloe vera, senna, castor oil for labour induction, bhasma preparations, various uterine-stimulant herbs, and Panchakarma procedures in pregnancy.

Limited or uncertain: most individual Ayurvedic formulations have few high-quality randomised trials in pregnancy. The reasons are real — preparations contain many ingredients at once, products vary between manufacturers and batches, contamination complicates interpretation, and long traditional use is not the same as proven modern safety. India does have a research infrastructure (CCRAS, AIIA, NIA, and journals such as the Journal of Ayurveda and Integrative Medicine and AYU), but pregnancy-specific evidence remains sparse.

What this means for you: be confident with the well-evidenced options (ginger, dietary variety, gentle yoga); be cautious and provider-guided with traditional-but-unstudied remedies; and avoid anything with evidence of harm. Pregnancy is a time to set the bar high for whatever goes into your body — a standard that applies equally to many over-the-counter ‘allopathic’ supplements, several of which also lack pregnancy safety data. When uncertain, the precautionary choice is the safer one.

Myths and facts about Ayurveda in pregnancy

When to see a doctor

Some situations need prompt medical care, not herbal remedies. Contact your obstetrician or go to the nearest hospital straight away if you have:

  • Vaginal bleeding or any fluid leaking from the vagina.
  • Strong or regular cramping or contractions before your due date — possible preterm labour.
  • Reduced or absent fetal movements in the second half of pregnancy.
  • Severe or persistent abdominal pain.
  • Severe headache, blurred vision, or sudden swelling of the face and hands — warning signs of preeclampsia.
  • Fever above 100.4°F (38°C) lasting more than 24 hours, or any breathing difficulty.
  • Severe vomiting with inability to keep fluids down (possible hyperemesis).
  • Cramping, diarrhoea or bleeding after taking any herbal preparation — stop it and seek care.

Also check in (non-urgently) with your doctor before starting any new Ayurvedic medicine or tonic, if you discover something you've been taking contains a bhasma or a contraindicated herb, or if an Ayurvedic provider suggests stopping a prescribed medication. In pregnancy, when in doubt, ask — it's always the safer choice.

Frequently asked questions

Is it safe to take ginger for morning sickness in pregnancy?

Yes. Ginger is one of the most studied and safest Ayurvedic remedies in pregnancy, endorsed by ACOG as a first-line non-drug option for nausea. Use about 1–1.5 g of dried ginger daily (250–500 mg, 3–4 times), or fresh ginger tea or candies, staying under roughly 4 g a day. Check with your doctor before using high doses for long periods.

Which Ayurvedic herbs should I avoid during pregnancy?

Avoid oral aloe vera, senna and castor oil (uterine stimulants or harmful purgatives), concentrated ashwagandha, brahmi, shatavari and triphala, high-dose fenugreek supplements, and any ‘menstrual regulator’ preparation. Also avoid all bhasma (calcined metal) products, which may contain mercury, lead or arsenic. Culinary amounts of common spices like ginger, cardamom, cumin and turmeric are generally fine.

Are bhasma (metal-based) Ayurvedic medicines safe in pregnancy?

No. Independent testing has found significant amounts of heavy metals such as mercury, lead and arsenic in some bhasma products, and these are established teratogens that cross the placenta. Avoid all bhasmas in pregnancy. For iron, calcium and other nutrients, use standard pharmaceutical-grade supplements instead.

Can I follow Garbhini Paricharya alongside my regular antenatal care?

Yes, with care. The lifestyle core of Garbhini Paricharya — rest, dietary variety, gentle movement and stress reduction — aligns well with modern advice. Skip the harsh detox procedures, oil enemas and vaginal oleation, avoid bhasmas and contraindicated herbs, and tell your obstetrician about anything you take so the two systems work together safely.

How do I choose a safe Ayurvedic practitioner in pregnancy?

Choose a registered BAMS doctor (ideally with a postgraduate qualification in obstetrics-gynaecology, Prasuti Tantra evam Stree Roga) practising at a recognised facility, and verify their registration on your state Ayurvedic medicine council's website. Avoid lay vaidyas and uncredentialled advisers. Be wary of anyone promising miracle cures, hiding ingredients, or discouraging you from seeing your obstetrician.

Why is castor oil not recommended to start labour?

Castor oil works only by causing strong diarrhoea, which often leads to distressing cramping and dehydration without reliably starting labour. It can also cause the baby to pass meconium, risking breathing problems at birth. Modern, safer induction methods — membrane sweeping, prostaglandins, a cervical balloon or oxytocin — are used under medical supervision when induction is needed.
