Shank Prakshalana: A Traditional Yogic Intestinal Cleansing Practice
A healthy intestinal tract plays an important role in our overall health and wellbeing.
Our lifestyle and choice of foods can have a significant influence on digestive health. We also now know that the microorganisms living in our gut interact closely with what we eat and that diet can influence the composition of the gut microbiome.
There are many approaches to supporting digestive health. One traditional yogic practice that I have personally used is called Shank Prakshalana.
Shank Prakshalana is a traditional practice intended to cleanse the gastrointestinal tract through drinking salted water combined with a sequence of specific yoga movements.
It is important to understand that this is a traditional yogic cleansing practice, not a medically necessary “detox.” It also isn’t suitable for everybody.
What Is Shank Prakshalana?
The traditional method involves drinking salted water and then performing a sequence of stretching and yoga movements.
These movements are intended to encourage the water to travel through the digestive tract.
The practice is performed on an empty stomach, usually in the morning. Traditionally, lighter food is eaten during the evening before the procedure.
The process can involve repeated rounds of drinking water, performing the movements and going to the toilet until the procedure is completed.
Because Shank Prakshalana involves consuming significant quantities of salt water, it should be approached carefully. People with medical conditions, particularly those affecting the kidneys, heart, blood pressure, gastrointestinal system or electrolyte balance, should seek appropriate medical advice before considering the practice.
Preparing for Shank Prakshalana
Traditionally, a light dinner is recommended on the evening before practising Shank Prakshalana.
I personally prefer to keep the meal simple rather than combining many different foods. In my practice, I have avoided heavy meals, meat and dairy products on the evening beforehand.
Shank Prakshalana is normally practised on an empty stomach and preferably early in the morning.
The traditional practice uses warm or room-temperature salted water followed by specific yoga exercises.
Different schools and teachers use somewhat different quantities and salt concentrations. For this reason, I don’t recommend improvising the salt concentration or attempting the practice for the first time without experienced guidance.
The Shank Prakshalana Exercises
After drinking the salted water, a particular sequence of yoga movements is performed.
The exercises are traditionally repeated several times on each side and in a particular order.
The intention behind these movements is to help the water progress through the digestive tract.
While performing the exercises, the lower body generally remains stable while the upper body performs the movements and stretches.
The sequence is then repeated after drinking more water.
If you feel the need to go to the toilet during the process, naturally stop the exercises and do so.
I have included a video reference below demonstrating the movements because seeing the exercises is considerably easier than trying to understand them from a written description.
Take Your Time With the Practice
The entire Shank Prakshalana process can take some time.
For that reason, I recommend not planning demanding activities immediately afterwards.
When the procedure is complete, give your body time to rest and recover.
Pay attention to how you feel. Significant weakness, dizziness, confusion, persistent vomiting, severe abdominal pain or other concerning symptoms should not simply be considered a normal part of cleansing. Stop and seek appropriate medical assistance if you become unwell.
Eating After Shank Prakshalana
Traditionally, food is eaten after completing the practice and allowing the digestive system some time to settle.
Different yogic traditions have slightly different recommendations for the first meal.
A simple preparation of cooked rice is commonly associated with traditional Shank Prakshalana aftercare.
Rather than treating the post-practice meal as another form of restriction or fasting, the purpose is to introduce simple food again and allow the digestive system to settle.
Normal hydration is also important after the procedure.
What About the Gut Microbiome?
Our intestines contain an enormous community of microorganisms collectively known as the gut microbiome.
Diet has a major influence on this ecosystem.
I previously recommended automatically taking bacteria capsules after Shank Prakshalana. I would phrase this more carefully today. There isn’t good evidence that everybody performing this practice necessarily needs probiotic supplements afterwards.
For general digestive health, a varied diet containing appropriate whole foods and fibre is usually more important than assuming that the gut needs to be artificially “repopulated.”
Individual needs, of course, can differ.
Who Should Avoid Shank Prakshalana?
Shank Prakshalana should not be treated as an ordinary wellness drink or casual home remedy.
Pregnant women should not practise it.
People with significant digestive, kidney, cardiovascular, blood-pressure or electrolyte-related conditions should seek professional medical advice before considering it.
The same applies if you take medication that can affect fluid or electrolyte balance.
If you are completely new to Shank Prakshalana, learning the practice from an experienced teacher is much wiser than trying to reproduce it from an internet article alone.
Keep the Practice Simple
There is a great deal of conflicting information about Shank Prakshalana on the internet.
Some variations are very complicated. Different teachers recommend different quantities, sequences and ways of completing the practice.
My own approach has always been to keep the practice as simple as possible.
What I have described here comes from my own experience with the practice. It should be understood in that context rather than as a replacement for individual medical advice.
Traditional practices can be valuable, but they should also be approached with respect for the body and common sense.
Enjoy your good health.
