Product Sources
Timber coming from Balsam fir is marketed with the spruces (Picea) in the Spruce-Pine-Fir grade.

Apart from timber, Balsam fir is also the source of many secondary products. The aromatic foliage is used in Christmas trees, wreaths, and balsam pillows. Canada balsam, an aromatic oleoresin produced from swelling or resin blisters in the bark, is used for mounting specimens for microscopes and for optical cement. Foliage of Balsam fir trees are also fodder for deer and moose in the winter season.
