Balsam \Bal"sam\, n. [L. balsamum the balsam tree or its resin,
   Gr. ?. See {Balm}, n.]
   1. A resin containing more or less of an essential or
      volatile oil.

   Note: The balsams are aromatic resinous substances, flowing
         spontaneously or by incision from certain plants. A
         great variety of substances pass under this name, but
         the term is now usually restricted to resins which, in
         addition to a volatile oil, contain benzoic and
         cinnamic acid. Among the true balsams are the balm of
         Gilead, and the balsams of copaiba, Peru, and Tolu.
         There are also many pharmaceutical preparations and
         resinous substances, possessed of a balsamic smell, to
         which the name balsam has been given.

      (a) A species of tree ({Abies balsamea}).
      (b) An annual garden plant ({Impatiens balsamina}) with
          beautiful flowers; balsamine.

   3. Anything that heals, soothes, or restores.
