Abstract
PERCIVAL, Food Science and Human Nutrition Department, The University of Florida, Gainesville, FL 32611, USA. ssp@gnv.ifas.ufl.edu reviewed (26 references) the medicinal use of echinacea.
Background
Echinacea (purple coneflower) is an herbal medicine that has been used for centuries, as a treatment for the common cold, coughs, bronchitis, upper respiratory infections, and some inflammatory conditions.
Methodology
Results
Conclusion
The authors conclude that the consensus of the studies reviewed in the article is that echinacea is indeed effective in reducing the duration and severity of symptoms, but that this effect is noted only with certain preparations of echinacea. Studies show that the plant and its active components affect the phagocytic immune system, but not the specifically acquired immune system.
