These Are the Most Effective Ways to Avoid Getting a Cold This Season

Though studies over the past few decades have yielded conflicting findings on the benefits of echincacea, a pooled analysis of these studies published in Lancet Infectious Disease found that, overall, echinacea appears to be associated with a small decrease in reported cold frequency, as well as a shorter duration of symptoms. But take note: the doses examined in the studies were high, typically around 300 mg three times a day, so it's unclear if the same benefits can be achieved at lower doses.
