Salt water (Saline solution) enema
This enema is a very soothing, very gentle enema. I do not find it the best for relieving bad constipation or for general cleansing. After using cleansing enemas, taking a saline solution enema to reduce the trauma of the cleansing process. If you have taken soapsuds enemas then this enema will clean out the soap residue from your colon.
Preparation of solution
Use either natural sea salt or non-iodized table salt. Do not use any iodized salt. Dissolve 4 teaspoons of salt into 2 quarts of warm water.
Start by flowing the enema into the bowels. Note that 2 quarts is a lot of liquid. If you experience any pain during insertion, stop the flow, remain in the same position, take deep breath and hold for a few seconds, expel your breath, hold for a few seconds and repeat until the pain subsides. Then resume the enema flow. If you expel the liquid before all of it has been inserted, simply begin the process over again. Hold the solution in your body for a few minutes before allowing it to be expelled. After two or three sessions, you will find it easier to insert and hold the liquid. You need to take the whole 2 quarts in the last session.
Repeat the above procedure until you have used up all 2 enemas of 2 quarts each. This may take 5 or more sessions. Expel and rest for 20 minutes.
I hope this helps you
