Borage (Borago officinalis). Borage is a common, enduring, annual herb of the Boraginaceæ family. Its seems that its name, derived from a mix of cor, the heart, and ago, to affect, because of its former use as a cordial or heart-fortifying medicine. Courage is from the same source. The Standard Dictionary, however, points to burrago, rough, and relates it indirectly by cross references to birrus, a thick, coarse woolen cloth worn by the poor during the thirteenth century.
