Homeopathic remedies are prescribed on the basis that in a tiny dilution like cures like, so while very dilute Echinacea Purpurea may help, unprocessed Echinacea Purpurea may be best avoided.
Below are the main rubriks (i.e strongest indications or symptoms) of Echinacea Purpurea in traditional homeopathic usage, not reviewed by the FDA.
Echinacea purpurea. Black Sampson. (Eastern States of America.) N. O. Compositae. Tincture of fresh root.
Diphtheria. Putrid fevers. clinical
I mention this plant, which is a popular remedy in the Eastern States, because it has been used in place of Echinacea Angustifolia Ech. ang. It has probably a very similar action, and the root causes the same pungent sensation on lips and tongue as the tincture of Echinacea Angustifolia Ech. 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.
