Shankha-prakshalana: a complete guide to intestinal cleansing at home

The human body is a remarkably resilient system, capable of maintaining health and repairing itself. However, modern lifestyles and dietary habits often lead to malfunctions, particularly within the digestive system, which can then affect other organs. While some accumulation of waste is inevitable, periodic cleansing practices can help reset the body. In yoga, one such technique is Shankha-prakshalana — a process of cleansing the entire digestive tract with salted water and specific exercises. This guide will explore the procedure's rules, effects, and important contraindications.

Shankha-prakshalana is one of the shatkarmas ('six actions'), which are methods used in Hatha yoga to cleanse the body's systems. In traditional texts, it can also be found under the name — varisara-dhauti. Shatkarmas help remove impurities, maintain health, support detoxification, and ensure the proper functioning of the body's energy channels.

To cleanse the digestive system and intestines, the procedure called Shankha-prakshalana is performed. Its name literally translates as 'washing/cleaning the shell (conch).' This practice is not simple, and it requires thorough preparation — especially before performing it for the first time. It is important to be mentally prepared, confident in your abilities and the outcome, carefully review detailed information about the practice, and preferably consult a specialist and secure their guidance. Ideally, the first procedure should be done under the supervision of an experienced instructor. You should also study possible risks and contraindications, and in case of doubts, consult a doctor and undergo any necessary examinations.

Proper attention should be given to the preparatory stage, allowing enough time and patience, as well as following lifestyle and dietary recommendations during the recovery period. All of this will be described in the following sections. Despite its apparent complexity, Shankha-prakshalana is worth the effort, as it offers a wide range of benefits for both the physical body and subtle bodies.

By gradually drinking a warm saline water solution and alternating this with yoga asanas, a process of deep cleansing is initiated, bringing the gastrointestinal tract to a more harmonious state. The procedure itself takes several hours, while preparation and recovery stages take several days (from 3 to 7). On average, shankha-prakshalana is performed 1–2 times per year, though it may be practiced more frequently when indicated.

Benefits of Shankha-prakshalana

Shankha-prakshalana has numerous positive effects on both the physical body and on the subtle bodies.

Main effects on the physical body:

• Cleansing and normalization of the gastrointestinal tract. Shankha-prakshalana is a yogic detox technique for the entire body, especially for the digestive system. During the practice, the digestive tract is cleansed of impurities, toxins, accumulated mucus, and bile. By removing this pathogenic environment, the small intestine becomes more efficient at absorbing nutrients. The smooth muscles of the intestine are stimulated, peristalsis and liver function improve, constipation disappears, and regular bowel movements are restored.
• Reduced load on the circulatory system. Cleansing the intestines decreases the penetration of toxins into the bloodstream, which can positively influence overall health and help reduce the occurrence of skin issues.
• Improvement of the genitourinary system in both men and women. The large intestine is anatomically close to the pelvic organs, and its condition directly affects their function. Shankha-prakshalana can help reduce infections on the lower reproductive tract.
• Relief from allergic conditions. Many allergens accumulate in the intestines, increasing the body's sensitivity to external irritants. Cleansing the intestines can help alleviate allergic reactions.
• Enhanced body odor and appearance. Shankha-prakshalana helps reduce skin rashes and acne, improves skin tone and complexion, and contributes to the brightening of the whites of the eyes. Breath becomes fresher, and unpleasant body odor and strong perspiration diminish. The body undergoes a process of renewal and regeneration.
• Overall improvement of well-being. Sleep becomes more balanced, and the body's resistance and protective functions strengthen.

Energetic effects:

• A more stable and harmonious connection emerges between the physical and energetic bodies.
• Energy channels and centers, including apana-vayu, are cleanced, allowing the release of energetic blocks and tension.
• The flow of prana (life energy) becomes smoother and more balanced.
• Mental clarity and sharpness of perception increase.
• The practice supports spiritual growth, self-awareness, and inner development.

Contraindications and risks

The many positive effects of this cleansing practice make it highly appealing, but before performing the procedure, it is important to weigh all the pros and cons, and carefully review contraindications and possible risks.

Contraindications for Shankha-prakshalana:

• Acute inflammatory diseases, fever;
• Malignant tumors;
• stomach and duodenal ulcers, gallstone disease, history of gastric or intestinal bleeding;
• menstruation, pregnancy, or breastfeeding;
• kidney diseases;
• endocrine disorders;
• increased blood clotting, pronounced varicose veins;
• cerebral the rosclerosis, heart conditions;
• tuberculosis;
• epilepsy.

Other restrictions.

Shankha-prakshalana can be performed no earlier than 3–4 weeks after food poisoning and one week after a three-day fast. Additional medical consultation is required if you have diabetes, bronchial asthma, glaucoma, hypotension, or any type of hernia (inguinal, umbilical, intervertebral, or hiatal hernia). Failure to follow procedural recommendations may lead to unpleasant consequences or disruptions in the functioning of the gastrointestinal tract.

The procedure itself takes about half a day, but both the preparatory stage and the recovery period play key roles in achieving a safe and effective result. Below is a step by step overview.

1. Preparation.
   Preparation for shankha-prakshalana is a long and responsible stage. It goes far beyond simply preparing the saline solution and setting up the space. For 2 to 5 days before the practice, it is advisable to follow a light diet, avoiding heavy and tamasic foods (meat, fish, eggs, alcohol, coffee) and focusing on grains and stewed vegetables. This greatly eases the cleansing process. The dinner on the eve of the practice should be light and not late. For the procedure, prepare at least 3–4 liters of boiled water. Ideally, have hot and cooled boiled water available so you can mix them to the right temperature without waiting. The solution is prepared using 9–10 grams of salt per 1liter of water (one heaping teaspoon). Sea salt is ideal, but rock salt or first-grade salt can also be used. Wear light, comfortable clothing and choose a space that allows you to perform asanas easily, with a toilet nearby. The practice can be done alone, but having an assistant who prepares the solution, cooks the first meal afterward, and provides emotional support can be tremendously helpful. A calm mind-set is essential. The procedure is usually done during warm spring or autumn months — extreme heat or cold may influence the results.
2. Procedure.
   To perform Shankha-prakshalana, you must set aside a full day free from obligations. The morning is dedicated to the practice itself, while the afternoon and evening are for rest and recovery. The procedure begins in the morning on an empty stomach, after completing your morning hygiene routine. The entire practice is a cycle of drinking a warm saltwater solution, performing a series of five exercises, and visiting the toilet. Begin by drinking two glasses of warm prepared solution, and immediately begin the following five exercises, repeating each one eight times. One repetition means performing the movement fully to both the right and left sides.
   • Talasana (Palm Tree Pose). Interlace your fingers above your head and stretch your whole body upwards, rising onto your tiptoes. Hold for 5–6 full breaths.
   • Tiryak-talasana (Swaying Palm Tree Pose). From Talasana, with the feet hip-width apart, perform gentle side bends to the right and left.
   • Kati-chakrasana (Waist Rotating Pose). Stand with feet hip-width apart. Twist your torso at the waist to the right and left, swinging your arms around your body naturally.
   • Tiryak-bhujangasana (Twisting Cobra Pose). Lie on your stomach with your palms on the floor under your shoulders. Push up to lift your torso, keeping a slight bend in the elbows. From this position, turn your head to look over your right shoulder at your left heel, and then to the left shoulder at your right heel.
   • Udarakarshanasana (Abdominal Massage Pose). Squat down with your feet hip-width apart and your hands on your knees. Twist to the right, lowering your left knee to the floor near the right foot, pressing your abdomen against your right thigh. Repeat on the other side.
   After this, it is necessary to drink two more glasses of the solution and repeat the exercises. When you feel the urge to visit the toilet, you should go. Then, repeat the entire cycle: drink the solution, perform the exercises, and visit the bathroom. The practice should continue until the water passed is transparent, or at least a light liquid without solid particles. Usually, about 16 glasses of solution are required, but more may be needed, as this varies individually. After finishing the water intake, several more bathroom visits may occur.
   Optionally, Shankha-prakshalana can be completed with two additional cleansing practices: kunjal-kriya and jala-neti. After the procedures, rest is necessary, but sleeping and drinking are not allowed for at least three hours. If thirst is intense, a few grains of salt can be dissolved in the mouth. The first meal should be 45–60 minutes after the procedure; it should be well-cooked, semi-liquid rice with added ghee. If you do not consume ghee, it can be omitted. The portion should be small and easily digestible. After eating, you should continue to rest, but you must not sleep. This is important. For the rest of the day, only this rice may be eaten; a small amount of lentils or mung beans is allowed.
3. Recovery.
   If possible, the day following Shankha-prakshalana should be spent in a gentle mode. It is very important to follow a diet for a week. There are quite a few restrictions, so it is easier to list what can be consumed:
   • grains, unleavened bread;
   • legumes (especially lentils and mung beans);
   • vegetables and not too sour fruits (initially cooked);
   • nuts (thermally processed, in small amounts);
   • ghee and vegetable oils;
   • herbal teas.

   It is important to introduce new foods gradually, listening to the body's reactions, and it is better not to rush, as the gastrointestinal tract has undergone a deep cleansing and digestion is weakened at this time. Unlike the diet, the usual lifestyle can be resumed 2–3 days after the procedure.

Yoga offers powerful practices, including body cleansing techniques, that promise excellent effects and well-being. Before starting the procedures, it is important to honestly ask yourself: how mentally prepared are you for them, and how ready is your body? It is advisable to approach this gradually by studying information and communicating with like-minded people, beginning with simpler and more accessible cleansing methods, such as mono-diet days, raw food diets, one-day fasting, or other cleansing techniques for the intestines and body.
