Balm (Melissa officinalis, Linn.), a perennial herb of the natural order Labiatæ. The popular name is a contraction of balsam, the plant having formerly been considered a specific for a host of ailments. The generic name, Melissa, is the Greek for bee and is an allusion to the fondness of bees for the abundant nectar of the flowers. Balm is a native of southern Europe, where it was cultivated as a source of honey and as a sweet herb more than 2,000 years ago. It is frequently mentioned in Greek and Latin poetry and prose. Because of its use for anointing, Shakespeare referred to it in the glorious lines
"Not all the water in the rough, rude sea
Can wash the balm from an anointed king."
