Shankhaprakshalana: The Yogic Practice of Deep Digestive Cleansing
As nature begins to change, we are gently reminded that our bodies and daily rhythms are also part of this ever-changing cycle. The days are becoming shorter, the air is becoming cooler and wetter, and the rainy season is approaching. This is why this is a great time to bring greater awareness to how we care for ourselves and for cleansing practices that will support us during this shift.
In Ayurveda, seasonal transitions are a natural time to pause, reset and support the body as it adapts to changes in nature. During the colder and wetter months, qualities associated with Kapha - such as heaviness, dampness and mucus - can increase, while stress and changes in our routines can also leave us feeling more congested and sluggish.
Traditionally, Shankhaprakshalana is practised twice a year, often around seasonal transitions, as a deeper way of clearing the digestive tract and creating a sense of lightness and renewal before nature shifts.
What is Shankhaprakshalana?
Shankhaprakshalana is one of the six traditional yogic purification practices known as the Shatkarmas (six methods of cleansing/purification).
The word Shankhaprakshalana comes from two Sanskrit words: shankha, meaning “conch,” and prakshalana, meaning “to wash thoroughly.” The name refers to the idea of cleansing the entire digestive tract, from the mouth and stomach through the intestines, using warm salty water and a specific sequence of yogic movements.
Unlike many modern approaches to cleansing, Shankhaprakshalana is not simply about fasting, taking laxatives, other pharmaceutical products, or herbs, or following a restrictive diet. It is a structured yogic practice that works with movement, breath, water, and the natural processes of elimination to encourage a thorough emptying of the digestive tract.
Shankhaprakshalana is working with the body’s natural mechanisms and is completely natural and free of chemicals.
The Six Shatkarmas
In Hatha Yoga, the Shatkarmas are a group of six purification practices traditionally used to prepare the body for deeper practices of yoga.
They are commonly described as:
Dhauti — cleansing practices for the digestive tract
Basti — traditional yogic colon cleansing
Neti — nasal cleansing
Trataka — steady gazing and cleansing of the eyes
Nauli — abdominal churning
Kapalabhati — a cleansing breath practice
How Shankhaprakshalana Works
The practice involves drinking warm saline water and then performing a sequence of simple yogic movements to help encourage the water to move through the digestive tract rather than remaining in the stomach. After drinking and moving, the practitioner goes to the toilet and allows the water to pass naturally through the bowels.
This process is repeated several times.
Traditionally, the practice continues until the water passing through the digestive tract becomes much clearer, indicating that the contents of the intestines have been largely eliminated. The sequence itself is quite simple, but the overall practice is not necessarily easy. It can be physically demanding, and the amount of water and salt involved means that it should not be approached casually, without appropriate instruction or a commitment from the practitioner to follow a healthy routine after the practice is finished.
The Role of the Yogic Movements
The asanas used during Shankhaprakshalana are not performed as a typical yoga sequence. The five asanas which form the core of the practice activate intestinal peristalsis and enhance the cleansing process. When performed in the correct sequence, they progressively open the pyloric valve at the outlet of the stomach, then the ileocaecal valve at the exit of the small intestine, and finally the sphincter which forms the anus.
The sequence includes these 5 asanas:
Tadasana variations
Tiryaka Tadasana
Kati Chakrasana
Tiryaka Bhujangasana
Udarakarshanasana
Each asana is repeated 8 times before returning to drink more water.
The combination of water and movement is what makes the practice distinctive
The movements gently compress, twist, and open different areas of the abdomen, helping encourage the movement of water through the digestive tract.
Tadasana acts mainly on the stomach and stretches the colon;
Tiryaka Tadasana acts on the small intestine and colon;
Kati Chakrasana massages the small intestine;
Tiryaka Bhujangasana and Udarakarshanasana squeeze and massage the caecum, sigmoid colon and rectum, and also stimulate the urge to defecate.
Why Do People Practise Shankhaprakshalana?
Shankhaprakshalana is practiced as a method of shuddhi — purification.
The intention is not simply to make the digestive system “empty.” Rather, cleansing the body and removing toxins from the body is traditionally understood as part of preparing oneself for deeper practices of yoga, meditation, and self-awareness - creating a sense of lightness and spaciousness in the body. It can feel like pressing a reset button on the digestive system.
What Happens Afterwards?
The period after Shankhaprakshalana is just as important as the cleansing itself.
Traditionally, the digestive system is considered delicate after the practice, and food is reintroduced gradually. 45 minutes of rest in shavasana is essential before eating a special meal - khichari - this is a simple, nourishing meal consisting of well-cooked rice and dal with a little ghee and turmeric. The intention is to provide something gentle and easy to digest while allowing the digestive system to rejuvenate.
For the same reason, the practice is generally followed by a longer period of simple eating and rest rather than immediately returning to heavy, highly processed, spicy, or difficult-to-digest foods. It is recommended to follow a good diet, free from meat and processed foods for 30 days afterwards.
This post-cleanse period is an important part of the practice and shouldn't be treated as an afterthought.
Shankhaprakshalana should be learned directly from a qualified and experienced teacher rather than attempted from written instructions alone and is considered a more advanced form of yogic purification. Contact me for guidance
It may also be unsuitable for people with certain medical conditions, including some digestive, kidney, heart, or blood-pressure conditions, and for people who are pregnant or otherwise medically vulnerable. If you have a health condition or take medication, speak with an appropriate healthcare professional before considering the practice.
Shankhaprakshalana as a Yogic Ritual
There is something quite profound about the traditional understanding of Shankhaprakshalana - it isn't only about cleansing the gut. The practice asks you to slow down, simplify, pay attention to the body, and consciously let go of what is no longer needed.
There is a rhythm to it: drink, move, release, rest.
Shankhaprakshalana reminds us that purification of our internal organs is not only about the physical body. It can also be an opportunity to become more aware of our habits, our relationship with food, our relationship with the body, and our ability to release and make space for something new.
When approached with the right preparation, guidance, and respect, it can be a deeply intentional yogic practice - one that connects the physical act of cleansing with the deeper yogic principle of shuddhi, or purification.
