Since this article is about a treatment whose benefits are disputed,it should tell readers how much it costs. This would let themdo a rough cost-vs.-benefit calculation as they consider whether touse echinacea. The reporter says the study showed a 58 percent reduction in cold risk, and some unspecified ability to shorten duration. It would be useful to know how likely an average adult or child is to get a cold each year, and how long it lasts. This would also helppeople understand the possible payoff of taking echinaceaand compare it to the costs. The articlepoints outthat the herb has some side effects, and quotes a physician mentioning the most common one (a rash, especially in children) and the most important contraindication (pregnancy). It also points out that the study did not take potential harms into account, alerting readers to the possiblity of othersnot mentioned here. The reporter does an excellent job of describingthe technique ofmeta-analysis, the details of this study, and the benefits and limits of this research approach. He also provides context by describing earlier research into the same question. The article does not exaggerate the effects of colds or the value of the treatment. The reporter does an excellent job describing the rigor of the study and getting the author, an interested party, and a disinterested party to provide perspective. The article fails to mention other options for treating and preventing colds. Again, due to the disputed nature of the findings, this is a significantoversight. The reader will want to know: If echinacea doesn't work, what else can I try? The article fails to sayhow widely the herb is used and where it's available. But it's probably safe to assume that most Americans know how to find it. The article makes very clear that this treatment has been studied many times before, with contradictory results. The reporter did a significant amount of original reporting.
