WHITE PLAINS, NEW YORK — TUESDAY, OCTOBER 10, 2006 — Autumn is the beginning of "cold season" — the period through early spring when people are most likely to develop a cold. But based on ConsumerLab.com's tests of sixty-six products with ingredients that may help prevent or treat a cold, people reaching for a natural remedy have a good chance of picking a product with no proven value or unsafe ingredients. ConsumerLab.com is providing a useful chart of its results and advice to help consumers choose properly and avoid being misled.
ConsumerLab.com has found that only 42% of herbal supplements made with echinacea, ginseng, or garlic have the right ingredients, in the right dose, and without lead contamination. Just-released test results for zinc lozenges show that only one of four products provided the dosage known to be effective in reducing the symptoms and duration of a cold. Vitamin C products have fared better in testing, but their effectiveness appears more limited.
"Some natural remedies may help people avoid or get over a cold — shortening it by two or three days and reducing symptoms — but many products don't provide the ingredients known to work," said Tod Cooperman, MD, President of ConsumerLab.com. ConsumerLab.com released the following chart with information and advice on popular natural remedies.
