balsam n.

c. 1200, basme, "oily, resinous aromatic substance exuding naturally from shrubs of the genus Commiphora," from Old French basme, baume, balme "balsam, balm" (12c., Modern French baume), from Latin balsamum, from Greek balsamon "balsam," from Hebrew (Semitic) basam "spice," which is related to Aramaic busma, Arabic basham "balsam, spice, perfume." The spelling was refashioned 15c.-16c. on the Latin model. Compare balsam.

As the name of a tree which yields the substance, it is attested from late 14c.; from mid-15c. it was extended to various fragrant garden herbs. Also by extension, "any aromatic preparation used in healing wounds or soothing pain, or as a perfume or in anointing" (late 14c.). Hence the transferred sense of "healing or soothing influence" (1540s). Biblical Balm of Gilead (esteemed for its medicinal properties) is from Coverdale (Jeremiah viii.22); the Hebrew word there is tsori, which was rendered in Septuagint and Vulgate as "resin" (Greek rhetine, Latin resina).

c. 1600, "health-giving," from balsam + -ic. From 1640s as "pertaining to balsam," 1670s as "yielding balsam," 1714 as "aromatic, fragrant." Balsamic vinegar is by 1849.
