An enema is a procedure that introduces liquids into the rectum and colon through the anus to be flushed out through the bowels. It is used as a treatment in Ayurveda and naturopathy for various medical conditions like constipation and digestive disorders. The standard procedure involves lying down with the buttocks raised, inserting a rubber catheter attached to an enema bag suspended 3 feet above, and allowing the liquid to flow in and be evacuated after 10 minutes of walking. Enemas vary based on size, temperature, and ingredients used. Coffee enemas have caused deaths and there are precautions to take as well as indications and contraindications for their use.
