Echinacea purpurea

Natural History.
      Echinacea purpurea.
      Black Sampson. (Eastern States of America.) N. O. Composite. Tincture of fresh root.

Clinical.
      Diphtheria.
      Putrid fevers.

Characteristics.
      I mention this plant, which is a popular remedy in the Eastern States, because it has been used in place of Echi. Ang. It has probably a very similar action, and the root causes the same pungent sensation on lips and tongue as the tincture of Echi. Ang. It well deserves a proving.
      The black root has been taken as a "signature" of the remedy in cases of low fevers where a black tongue was observed.
