What is Shankhaprakshalana?
Shankhaprakshalana derives from two Sanskrit words: ‘shankha’ meaning conch shell and ‘prakshalana’ meaning washing or cleansing — together translating to “the conch cleansing.” Pronounced shahnk-prah-kshah-LAH-nah, the practice is also known in English as Conch Cleansing Kriya or Master Cleanse. Importantly, Shankhaprakshalana is not a single asana but a complete yogic cleansing practice (kriya) — combining the consumption of warm salt water with a specific sequence of five asanas to flush the entire gastrointestinal tract from mouth to anus. The “conch” name reflects the spiral shape of the digestive tract that the practice systematically cleanses.
Critical safety note: Shankhaprakshalana is one of the most demanding traditional yogic cleansing practices and carries genuine medical risks if performed improperly. It must be undertaken only under the direct supervision of a qualified yoga teacher experienced in cleansing kriyas, and ideally with prior medical clearance. This guide provides educational information only — not standalone instruction for self-practice.
The practice is documented in classical Hatha yoga texts including the Hatha Yoga Pradipika and the Gheranda Samhita as one of the six purification techniques (shatkarma). It was systematically codified and popularised in the modern era by Swami Satyananda Saraswati of the Bihar School of Yoga in his foundational text “Asana Pranayama Mudra Bandha.” The traditional purpose is comprehensive intestinal cleansing — moving roughly 1.5–3 litres of warm salt water through the entire digestive tract using a specific sequence of asanas to drive the water through. A lighter version called Laghoo Shankhaprakshalana exists for less experienced practitioners and is recommended as the introductory version.
In the broader yoga system, Shankhaprakshalana belongs to the family of shatkarma (six purification techniques) alongside Neti (nasal cleansing), Dhauti (digestive tract cleansing), Nauli (abdominal massage), Kapalabhati (skull cleansing breath), and Trataka (concentrated gazing). It is most commonly practised once or twice yearly under guided supervision — never as a frequent or casual practice. The intensity and risks involved make it categorically different from the daily asana practice most yoga students perform.
Shankhaprakshalana Benefits
Physical Benefits
Benefit 1: Comprehensive Gastrointestinal Cleansing
The most direct benefit. Shankhaprakshalana mechanically flushes the entire digestive tract — from oesophagus to small intestine to colon — removing accumulated waste, mucus, and stagnant matter that ordinary digestion cannot fully address. Practitioners report dramatic improvements in digestive function for weeks following the practice. Members focused on broader digestive support often pair their work (where appropriate and under guidance) with our yoga for digestion programme.
Benefit 2: Resets Gut Flora and Supports Microbiome Health
The cleansing creates an opportunity to systematically rebuild healthy gut flora through prescribed post-practice diet. Combined with the gentle re-introduction of probiotic foods, the practice supports broader microbiome health. Members focused on broader gut health often pair their practice with our yoga for gut health programme.
Benefit 3: Supports Liver and Kidney Function
The salt water solution and movement sequence stimulate liver and kidney function — supporting the broader detoxification systems that healthy ageing depends on. Members focused on broader liver support often pair their practice with our yoga for liver programme.
Mental and Emotional Benefits
Benefit 4: Builds Mental Discipline and Patience
The 2–3 hour duration of the practice — combined with the dietary preparation and recovery requirements — builds significant mental discipline. The practice teaches patience and process-orientation in ways few other practices can replicate.
Benefit 5: Produces Lightness and Mental Clarity
Practitioners report significant lightness, mental clarity, and improved energy in the days following Shankhaprakshalana. The traditional yogic interpretation connects the digestive cleansing with the corresponding lightness of consciousness. Members managing concurrent stomach concerns often pair their work with our yoga for stomach programme.
Benefit 6: Supports Long-Term Yoga Practice Foundation
For dedicated yoga practitioners, the periodic practice of Shankhaprakshalana (1–2 times yearly under guidance) supports the digestive lightness that classical yogic texts associate with deeper meditation states.
How to Do Shankhaprakshalana — Step-by-Step Instructions
CRITICAL: This guide is educational reference only. Shankhaprakshalana must be practised under the supervision of a qualified yoga teacher. Self-practice without guidance carries genuine medical risks.
Key Principles
Three foundational principles must be in place before attempting: medical clearance from a doctor (particularly important for those with any health condition), guidance from an experienced kriya teacher, and 1–2 days of dietary preparation prior to the practice (light, easily digestible food only).
Step 1: Preparation — Warm Salt Water
Prepare 2–3 litres of warm filtered water (body temperature) with sea salt or rock salt added at the rate of approximately 1 teaspoon per litre. The salt concentration prevents the water from being absorbed by the intestines, allowing it to flow through the digestive tract. Begin practice on an empty stomach in the morning.
Step 2: Drink Two Glasses of Salt Water
Drink two glasses (approximately 400 ml) of the warm salt water continuously without pause. The water will sit in the stomach until the asanas drive it through the digestive system.
Step 3: Perform the Five Specific Asanas
Perform the prescribed five asanas in sequence — Tadasana (standing palm tree), Tiryaka Tadasana (swaying palm tree), Kati Chakrasana (waist rotation), Tiryaka Bhujangasana (swaying cobra), and Udarakarshanasana (abdominal stretch). Each asana performed 8 times in sequence. The asanas systematically drive the water through different sections of the digestive tract.
Step 4: Repeat the Drinking and Asana Cycle
Repeat the cycle of drinking 2 glasses of salt water followed by the 5 asanas. Continue for 6–8 cycles or until water begins to pass through the system as elimination. The complete practice typically takes 2–3 hours.
Step 5: Final Position — Eliminate and Continue Until Clear
Continue the cycle until the water passing through is mostly clear (similar in colour to the water being consumed). This signals that the digestive tract has been cleared. Most practitioners require 12–16 glasses total. After completion, rest in Savasana for 30–45 minutes.
Step 6: How to Come Out of Shankhaprakshalana
After the rest period, the practitioner must consume a specific recovery meal — traditionally khichdi (rice and dal) with ghee, prepared without significant spices. This meal coats the intestinal walls and provides the gentle restoration the cleansed digestive tract requires. Avoid all other food for 12 hours after the practice.
Breathing in Shankhaprakshalana
Throughout the practice, maintain steady deep diaphragmatic breathing. Avoid breath-holding during the asanas. The practice is physically demanding — smooth steady breath supports both performance and safety.
Preparatory Poses Before Shankhaprakshalana
Preparation extends well beyond yoga poses — encompassing dietary preparation, mental readiness, and qualified guidance.
Laghoo Shankhaprakshalana (Lighter Version)
The introductory version of the practice — uses fewer glasses and requires less commitment. Should be practised first before attempting full Shankhaprakshalana.
Daily Asana and Pranayama Practice
A consistent daily yoga practice of at least 6–12 months provides the foundation that Shankhaprakshalana requires.
Light Dietary Preparation (1–2 Days Prior)
Easily digestible foods, no caffeine, no heavy proteins for 24–48 hours prior to practice.
Medical Clearance
Consultation with a doctor regarding any existing conditions before attempting the practice.
Variations of Shankhaprakshalana
Variation 1: Laghoo Shankhaprakshalana (Light Conch Cleansing)
Difficulty: Beginner
Uses fewer glasses (typically 4–6 cycles) and focuses on the upper digestive tract only. The mandatory introductory version before attempting full Shankhaprakshalana.
Variation 2: Standard Shankhaprakshalana
Difficulty: Advanced
The complete cleansing practice described in this guide — requires 12–16 glasses and 2–3 hours under supervision.
Variation 3: Modified Shankhaprakshalana for Specific Conditions
Difficulty: Therapeutic
Modified versions for specific conditions, always under direct medical and yogic supervision. Members focused on broader stomach concerns often pair their work with our yoga for stomach programme.
Variation 4: Annual Practice Schedule
Difficulty: Advanced Practitioner Schedule
Some practitioners follow seasonal cleansing schedules (1–2 times yearly) under guidance — never frequent practice.
Common Mistakes to Avoid in Shankhaprakshalana — and Side Effects
Mistake 1: Attempting Self-Practice Without Qualified Guidance
The most dangerous mistake. Self-practice without a qualified teacher risks severe dehydration, electrolyte imbalance, and other complications. Correction: only attempt under direct supervision of an experienced kriya teacher.
Mistake 2: Ignoring Medical Contraindications
Shankhaprakshalana is contraindicated for: hypertension (high blood pressure), heart conditions, hernias, ulcers, hyperthyroidism, diabetes, kidney disease, pregnancy, breastfeeding, and several other conditions. Correction: consult a doctor before attempting; do not practise if any contraindication applies.
Mistake 3: Skipping the Recovery Diet
The post-practice khichdi meal is mandatory — skipping it can cause digestive distress and undermine the practice’s benefits. Correction: prepare the recovery meal before beginning the practice; consume it within 30–45 minutes of completion.
Mistake 4: Practising Too Frequently
Shankhaprakshalana is intended for occasional practice (1–2 times yearly maximum). Frequent practice can deplete electrolytes, disrupt gut microbiome, and cause weakness. Correction: respect the traditional practice schedule — never more than twice yearly.
Mistake 5: Ignoring Side Effects
Common side effects include weakness, fatigue, mild headache, and dehydration. More serious effects (severe weakness, electrolyte imbalance, fainting) require immediate medical attention. Correction: monitor for side effects; seek medical care if symptoms persist or worsen.
Mistake 6: Practising During Illness or Stress
The practice requires significant physical reserves — attempting it during illness, stress, or weakness can cause dramatic complications. Correction: practise only when in good general health and with adequate emotional and physical reserves.
Who Should Practise Shankhaprakshalana?
Experienced Yoga Practitioners Under Qualified Guidance
The audience that benefits most. Practitioners with 6+ months of consistent yoga foundation, medical clearance, and access to qualified kriya teachers find Shankhaprakshalana a powerful occasional practice. Members focused on broader liver support often pair their work with our yoga for liver programme.
Is Shankhaprakshalana Good for Beginners?
No — Shankhaprakshalana is not appropriate for yoga beginners. New practitioners should establish 6+ months of consistent daily yoga before considering Laghoo Shankhaprakshalana, and only then progress to full Shankhaprakshalana under supervision.
Those with Specific Digestive Concerns (Under Medical Guidance)
For those with specific digestive conditions where the practice may help, the cleansing must be done under combined medical and yogic supervision. Disclaimer: never attempt self-treatment of medical conditions through this practice. Members focused on broader gut health often pair their work with our yoga for gut health programme.
Practitioners Following Traditional Yogic Schedules
Dedicated practitioners following traditional yogic cleansing schedules (typically 1–2 times yearly aligned with seasonal transitions) integrate Shankhaprakshalana into their broader practice. Members focused on broader stomach support often pair their training with our yoga for stomach programme.
Frequently Asked Questions about Shankhaprakshalana
What is Shankhaprakshalana?
Shankhaprakshalana is a traditional yogic cleansing practice (kriya) where the practitioner consumes warm salt water and performs a specific sequence of five asanas to flush the entire gastrointestinal tract from mouth to anus. It is documented in classical Hatha yoga texts.
Is Shankhaprakshalana Good for Beginners?
No — it is not appropriate for yoga beginners. New practitioners need 6+ months of consistent daily yoga foundation before considering even the lighter version (Laghoo Shankhaprakshalana). Always practise under qualified supervision.
What is the Difference between Shankhaprakshalana and Laghoo Shankhaprakshalana?

Can Shankhaprakshalana Help with Weight Loss?
The practice is not intended as a weight loss method. Any temporary weight loss is primarily water and waste — not fat loss. Sustainable weight management requires consistent diet and exercise, not periodic cleansing.
How Many Calories Does Shankhaprakshalana Burn?
Caloric burn is not the purpose. The practice removes waste material and supports digestive health. The 2–3 hour duration involves moderate physical activity but the primary effect is cleansing, not exercise.
How Often Should I Practice Shankhaprakshalana?
1–2 times yearly maximum, ideally aligned with seasonal transitions and under qualified supervision. Frequent practice depletes electrolytes and can disrupt healthy gut microbiome function.
What Are the Side Effects of Shankhaprakshalana?
Common side effects include weakness, fatigue, mild headache, and dehydration during and after the practice. More serious effects include electrolyte imbalance, severe weakness, or fainting. Contraindicated for hypertension, heart conditions, ulcers, hernias, pregnancy, and several other conditions. Consult a doctor before practising.
Can I Do Shankhaprakshalana at Home Online?
No — Shankhaprakshalana requires direct in-person supervision by an experienced kriya teacher. Online videos cannot provide the safety oversight this demanding practice requires. Workshop settings with qualified teachers are essential.
