. MEDICAL: DISEASES: COMMON COLD Echinacea No Big Impact On Common Cold Echinacea No Big Impact On Common Cold Main Category: Flu / Cold / SARS Also Included In: Complementary Medicine / Alternative Medicine; Nutrition / Diet Article Date: 21 Dec 2010 - 2:00 PST Medical News Today http://www.medicalnewstoday.com/articles/212112.php Although popular as an over-the-counter herbal treatment for the common cold, researchers say echinacea has no big impact and only reduces duration of symptoms by half a day at the most. Lead researcher Dr Bruce Barrett, an associate professor of family medicine at the University of Wisconsin-Madison School of Medicine and Public Health in Madison, Wisconsin, USA, and colleagues, published their findings in the 20 December issue of Annals of Internal Medicine. The botanical genus Echinacea, also known as purple coneflower, is a wild flower that is native to North America, where indigenous peoples have used it in various forms for a variety of illnesses. It became popular as a remedy for respiratory infection and other illnesses in the rest of the world after early research was done in Germany in the 1920s, wrote the authors. Most commercially available echinacea products are made primarily from 2 species: Echinacea purpurea and E. angustifolia. Echinacea has been used in homemade remedies in the form of teas, dried herb and liquid extracts, and a supplement form is available as capsules sold in drug and retail stores. For this study, the researchers used a root-based preparation of the herb. Barrett and colleagues wrote in their introduction that by the mid 1990s there were several hundred published studies on echinacea, including over a dozen randomized trials, nearly all reporting benefits for treating the common cold, but all were "manufacturer-sponsored and of moderate to poor quality". Since then there have been several trials, some with positive results, and some with negative results, including one by Barrett and his team, which also produced negative results. Systematic reviews on these studies also varied in their results and interpretation. "We designed and conducted this trial because the effectiveness of echinacea was still unclear," wrote the authors. The complete article may be read at the URL above.
