bor·age (bôr'ĭj, bŏr'-) n. An annual, bristly European herb (Borago officinalis) having blue or purplish star-shaped flowers.
[Middle English, from Old French bourage, from Medieval Latin borāgō, probably from Arabic bū'araq, from 'abū 'araq, source of sweat (from its use as a sudorific) : 'ab, father, source; see b in Semitic roots + 'araq, sweat; see ʕrq in Semitic roots.]
flowering plant used in salads, c.1265, from Anglo-Norm., from O.Fr. borrace, from M.L. borrago. Klein says it's ult. from Arabic abu drak, lit. "the father of sweat," so called by Arab physicians for its effect on humans. But OED says it's from L. borra "rough hair, short wool," in ref. to the texture of the foliage.
