Do Colonics help with Constipation?

It is common sense that colonics help constipation, because constipation is caused by dehydration, among other things. In a one-hour session, you will have 25-30 gallons of water flow through your large intestine. Much of the stuck fecal matter will absorb water, soften, and fall off the intestine wall, flowing out with the water. It certainly cannot hurt, only help.
