USES: Black Sampson Echinacea contains pain-reducing compounds and was used by Native Americans to treat toothaches, sore throats, mumps, wounds, and burns.

COMMENTS: Echinacea is from the Greek word for "hedgehog", which is in reference to the spiny bracts of the disk flowers. The taproot can grow to 5-8 feet, allowing the plant to survive periods of drought.
