Herb Remedies: Echinacea for Colds and Flu
The root of this daisy-like flower revs up the immune system. According to an analysis by University of Wisconsin researchers, in eight of nine studies evaluating echinacea for upper-respiratory infections, the herb reduced symptoms and accelerated recovery compared with placebos. "As soon as I feel a cold coming on, I take it--and my cold is mild and brief," says Duke. Echinacea is available in teas and capsules, though most herbalists prefer tinctures. Liquid echinacea products may cause temporary, harmless numbing or tingling of the tongue; minor stomach upset is possible with tinctures.
