A new study raises new questions about the safety and effectiveness of colon cleaning.

Proponents of colon cleansing believe the process helps purify the body and treat certain diseases.

But a new report says colon cleansing offers no benefits and can actually be harmful.

Colon cleansing can be accomplished in a variety of ways, including supplements and flushing out the colon with water and other substances such as coffee.

Researchers at Georgetown University reviewed published case studies and found that most of them noted numerous adverse effects, from mild cramping and nausea, to serious effects such as kidney failure.
