Solidago virgaurea L COMPOSITAE
The common name refers to the herb's appearance. It is an attractive plant and has been taken into cultivation as a useful late-flowering ornamental.
The herb is not certainly mentioned in ancient writings and there is evidence that it was particularly promoted by the Arabs in the Middle Ages, since to fifteenth and sixteenth century Italians it was known as Erba pagana and the Germans called it Consolida Saracenia. Golden Rod has principally been used as a wound herb, hence the name consolida from the Latin to make whole - and hence its generic name. Traditionally it was employed both externally and internally. Clarke introduced an extract of the fresh flowers to homeopathic medicine in igo2, and in 1949 it was discovered by Hager that Brazilians used the closely related herb S. microcosms DC as a wound plant, too.
