Study Says Echinacea Won't Ease Or Cure Your Cold...
New York Times :
Echinacea, the herbal supplement made from purple coneflower and used by millions of Americans to prevent or treat colds, neither prevented colds nor eased cold symptoms in a large and rigorous study.
The study, being published today in The New England Journal of Medicine, involved 437 people who volunteered to have cold viruses dripped into their noses. Some swallowed echinacea for a week beforehand, others a placebo. Still others took echinacea or a placebo at the time they were infected.
