Findings of a review of 14 earlier studies by researchers at the University of Connecticut published in The Lancet Infectious Diseases suggest that it might be wise to keep Echinacea on hand during cold season. They found that this herb, long used by Native Americans of the U.S. Midwest, can reduce the risk of catching a cold by 58 percent and shorten a cold’s duration by nearly a day and a half. Further investigation is needed to determine dosages, preparation and the best species of the herb to use.

Meanwhile, integrative pioneer Dr. Andrew Weil says that a recommended dose for adults is two capsules of freeze-dried extract four times a day or one teaspoon of the tincture in a little warm water at the same frequency. He adds that half this amount can boost immunity in otherwise healthy adults. While Weil agrees that more research will help people sort through current confusion about this herb, he sees it as a worthwhile first-line of treatment for the common cold, sore throats and episodes of low resistance.
