The water is gently injected into the colon through the rectum using a pipe connected to a device designed for this purpose. Maintained inside the intestine, the liquid dislodges what is in it (stools, mucus, toxins, acid, etc.) even in the smallest folds.
Then the water comes out taking with it the waste and buildup. As everything is done in "closed circuit", the hydrotherapy of the colon, or irrigation of the colon, is completely odorless. In short, irrigation of the colon is a profound cleanse.
