   Balm of Gilead (Bot.), a small evergreen African and
      Asiatic tree of the terebinthine family (Balsamodendron
      Gileadense). Its leaves yield, when bruised, a strong
      aromatic scent; and from this tree is obtained the balm of
      Gilead of the shops, or balsam of Mecca. This has a
      yellowish or greenish color, a warm, bitterish, aromatic
      taste, and a fragrant smell. It is valued as an unguent
      and cosmetic by the Turks. The fragrant herb
      Dracocephalum Canariense is familiarly called balm of
      Gilead, and so are the American trees, Populus
      balsamifera, variety candicans (balsam poplar), and
      Abies balsamea (balsam fir).
