"There is general disagreement in the health field on the best way to detoxify the body. The Hygienists, who are mostly followers of Dr. Herbert Shelton , the very capable exponent of fasting, using only distilled water, and enemas are taboo. Dr. Shelton and other Hygienist doctors have fasted thousands of people, many regaining their health, as a result of the fast. Of course, after the fast, it was necessary for them to follow a healthful way of life. The Hygienists are strict vegetarians with the emphasis on raw foods and proper combinations.
Dr. Walker and Dr. Airola advocate fruit and vegetable juice if fasting is needed. In Europe, naturopaths use the vegetable broth and vegetable juice fast rather than the water fast. The above doctors also employ colonics and enemas, these being vital for the success of the program. The purpose, in their opinion, is to rid the body of the toxins loosened by the cleanse."
So you can see, even the professionals are in disagreement as to do enemas or not. Do what you feel is best for you. I personally don't believe in them. To me they are not natural. You don't see animals doing this out in nature. I also know some people will come back that the animals haven't done what we have done to our bodies (cooked/processed foods). But I have such a strong feeling against them, that I know this is not what my body wants. I'll do the slow cleaning out - cleanses and eating raw.
