NORTHRIDGE, Calif. (July 27, 2005) — Pharmavite LLC, maker of Nature Made vitamins and Nature’s Resource herbal supplements, today cautioned against applying the conclusions of an Echinacea study published in this weeks edition of the New England Journal of Medicine to real world application due to the study’s limitations. The study concluded that laboratory-produced Echinacea did not have a measurable effect in this trial. However the researchers only tested Echinacea angustifolia root, which is not widely used by the industry. Most Echinacea products, including Pharmavite’s, utilize the aerial parts of Echinacea purpurea, a more widely-studied form of Echinacea.
Herbal experts also question the dosage used in the trial. According to the American Herbal Product Association (AHPA), the standard dosage for E. angustifolia is three grams or more per day. This study used less than one gram. In addition, the E. angustifolia preparations may not have been standardized in accordance with acceptable recommendations.
“It is unreasonable, not to mention un-scientific, to accept conclusions based on what is likely an insufficient dose,” said David Madsen, Ph.D., Pharmavite director of scientific affairs. “Who would use any product in such a manner?”
Dr. Madsen adds, “We welcome new research on Echinacea, especially if it is well designed and interpreted. My concern is that people will take this study as the definitive answer and applicable to all Echinacea products, and that would be a disservice to the many people who can and do benefit from this herb.”
Echinacea’s primary benefit is to enhance the immune system. Taken at the first sign of feeling under the weather, Echinacea may boost the body’s immunity. Echinacea should not be taken continuously for more than two weeks, and is not recommended for those with allergies to plants in the daisy family, such as ragweed, or who are on medications that affect liver function.
