What to add to the enema liquid? Well it depends on what you are trying to accomplish.
For a very gentle cleanse, you could add 2 teaspoons of non-iodized table salt or sea salt per quart of water.
For a very cleansing enema add 2 teaspoons of Castile soap per quart. For a deep cleansing enema use 2 quarts of this soapsuds enema and take a least 3 enemas one after the other, evacuating after each enema. This is called a series enema.
