Echinacea angustifolia (Compositae)
CONEFLOWER, PURPLE CONEFLOWER, KANSAS SNAKEROOT
The roots and rhizome are being
studied as a possible treatment for AIDS. Coneflower is also used by
herbalists as an antiviral remedy for infections ranging from tonsillitis to
blood poisoning.
For over 100 years, coneflower has been known to increase resistance to infections; both North American Indians and the early settlers used it to clean and heal wounds, against infectious disease, and even to cure snakebites. Scientific research has now confirmed its stimulatory effects on the white blood cells that fight infection, and it is being studied in California as a possible treatment for AIDS. A native of central and southwestern United States and widely grown in gardens across the world, it is a perennial with coarse hairy stems and leaves. Flowers comprising a central, raised, daisylike cone and an outer ring of purple florets appear in late summer.
