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).
