"Echinacea" or the "Purple Cone Flower"

Echinacea has been contributed
with the ability to boost the body's
immune system and to ward off
infections, particularly the common
cold. Bought in drugstores, along
with zinc, echinacea really does work.
At the first sign of a cold setting in, or
feeling run down, zinc and echinacea
really knock it out of you.
