The term natural colon cleansing and colon cleansing might seem to need a little explanation. With the interest in food supplements being sold as colon cleansers one might think of a regiment of herbal pills as being natural colon cleansing regiments. Most people, however, think of the word natural as implying something that is done without specific herbs or medications.
Of course, it is useful to use a natural herbal supplement program to cleanse the colon. To say that you would die without it, and therefore make it necessary, is not yet proven. To say that using a natural herbal supplement program to cleanse the colon makes you feel better and cleanses your intestines of parasitic and accumulated wastes and toxins is truthful.
The question is what is necessary may mean different things to different people. It is necessary to eat healthy and stay healthy. It is not necessary to follow a natural colon cleansing program to stay alive. However, cleansing of the colon was incorporated in many cultures as part of their religious beliefs. The reasoning has long been lost but the practice of natural colon cleansing habits has continued.
Fasting in many religions was considered a sign of purification of the inner self that was necessary to purify the whole body before taking communion.

If you were a member of one of those religions then natural colon cleansing was necessary for you to continue to belong to your religion.
