I agree with the above poster, that it shouldn't be done without a doctor's supervision. There are those cleansing pills that clean out your intestines, etc, and will even get rid of any worms if you have any. A relative of a friend of mine did that and sure enough; she had had worms. So gross, but I guess it's better for your health to get rid of them. I've heard that approximately 1/3 of humans have them in their intestines.
I got a bit off topic - sorry!
