Colon cleansing: Not so healthy, analysis says – The Chart - CNN.com Blogs

Now researchers from Georgetown University in Washington, D.C. say there's no evidence any of these colon cleansing treatments work and, in fact, when used improperly can cause cramping, kidney failure and in some extreme cases, death.

"Colon cleansing products in the form of laxatives, teas, powders and capsules... tout benefits that don't exist."

Although colon cleansing has been around for centuries as a way to rid the body of unwanted toxins, the American Medical Association determined in the early 1900s that the procedure was invalid; there was no evidence to show the methods worked.

Investigators noted while these reports showed little evidence of colon cleansing benefits, there were a number of side effects reported following the use of these cleansing methods.

Zinc may curb cold symptoms – The Chart - CNN.com Blogs

When they compiled the evidence, the researchers found that healthy adults and children who took zinc syrup, lozenges, or tablets within 24 hours of their first cough or sniffle experienced shorter and less severe colds than the participants who took a zinc-free placebo.

Taking zinc reduced the odds that a person would still be experiencing symptoms at the seven-day mark by more than half.

Zinc—a mineral that occurs naturally in nuts, seeds, meats, fruits, and vegetables—also appeared to help prevent colds.

Study participants who took zinc syrup or lozenges daily for at least five months cut their chances of developing a cold by about one-third, on average.

We need to take precautions, particularly with long-term use, but I'd still recommend it to my patients at the first sign of cold symptoms."
