Those with specific medical conditions like asthma, stomach ulcers, etc should seek the help from qualified yoga instructors before attempting it.
2- Basti – The Yogic Enema Technique

It is aimed at cleansing the lower intestines and the colon.

How to do Basti? Sit in a tub filled with water. The water should reach up to the navel. Ideally this is done in a river with a gentle flow of water. Completely exhale and perform uddyan bandha by sucking in the stomach. This vacuum allows the water to shoot up through the anus and into the rectum and colon. After a few rounds, discharge the excess water.
The traditional method of Basti has given way to simpler methods of enema in modern times.

Benefits of Basti
1- Removes impurities and cleanses the colon, thus detoxifying the large intestine.
2- Relieves gas formation in the large intestine.
