Study: Echinacea Has No Effect for the Common Cold

Photo Courtesy - Getty Images(NEW YORK) -- Researchers say the herbal supplement and age-old household cold remedy echinacea, was found to have no effect on the duration or severity of the common cold, according to the news service MedPage Today.

Results from the Wisconsin Upper Respiratory Symptom Survey showed that there was some trend for improvement, but study authors reported that only one in four people considered the degree of benefit to be worth the cost and time involved.

"Individual choices about whether to use the echinacea to treat the common cold should be guided by personal health values and preferences, as well as by the limited evidence available," researchers said.
