Balsam, balm meaning a fragrant, perennial herb. 

It is native to Europe and has been introduced into North America. Balm has long been cultivated in gardens. The stems and leaves, formerly used in medicine as a gentle stimulant and tonic, are still occasionally used as such. The taste is somewhat astringent and the odor slightly aromatic. A variety of the common catnip, with an odor like that of balm, is often mistaken for it. Balmlike properties are common among the mints. The term balm is applied to several resins obtained from balsam fir trees.  The balsam stand approximately 50-80 feet in height.  Their needles contain sap which sometimes is used to make a  sweet gum similar to spruce.  It grows in northeastern regions of the United States.  It is used for lumber and paper products also.  Not recommend for cooking purposes.
