Definition - What does Danda dhauti mean?
Danda dhauti is a yogic purification technique designed to remove excess bile from the stomach and excess mucus. Traditionally, danda dhauti was performed by threading a lotus or banana stem down the throat. While that method is still used, the modern way of practicing danda dhauti is to use a catheter.
After the yogi drinks warm saltwater, the catheter is guided through the esophagus into the stomach and then removed. Danda dhauti should only be practiced with the help of an expert.
Yogapedia explains Danda dhauti
Danda dhauti is one of three types of hrida dhauti (heart or thoracic cleansing), the others being: vastra dhauti, in which a thin strip of cloth is swallowed, and vaman dhauti, which is the drinking of saline water followed by regurgitation.
In addition to removing bile and mucus, danda dhauti is believed to reduce acidity and other digestive issues and to improve bad breath. It is traditionally practiced in utkatasana (crow pose).
Yogis who suffer from heart disease, high blood pressure, ulcers or hernias should not practice danda dhauti.
