The most important immune stimulant in Western medicine.

Echinacea enhances the particle ingestion capacity of white blood cells and other specialized immune system cells, thus increasing their ability to attack foreign invaders, such as cold or flu viruses. Besides stimulating a healthy immune system to deal more effectively with invading viruses, it helps accelerate healing if infection already exists.

A 1992 German double-blind, placebo-controlled study of 180 volunteers found that a dose of 4 droppers of tincture (equivalent to 900 mg of dried root) of Echinacea purpurea root decreased symptoms and duration of flu like infections. More clinical studies are needed to determine clear therapeutic indications, the best preparations, and the most effective dosage. The best-studied echinacea is a preparation made from the fresh expressed juice of Echinacea purpurea. No single chemical component has been identified as causing echinacea's medicinal action, but it may involve flavonoids, essential oils, polysaccharides, caffeic acid derivatives, alkylamides, and other compounds.
