 "Canada balsam, also called Canada turpentine or balsam of fir, is a turpentine which is made from the resin of the balsam fir tree (Abies balsamea) of boreal North America. The resin, dissolved in essential oils, is a viscous, sticky, colourless or yellowish liquid that turns to a transparent yellowish mass when the essential oils have been allowed to evaporate... Due to its high optical quality and the similarity of its refractive index to that of crown glass (n=1.55), purified and filtered Canada balsam was traditionally used in optics as an invisible-when-dry glue for glass, such as lens elements... Canada balsam was also commonly used for making permanent microscope slides." \\ "Canada balsam, also called Canada turpentine or balsam of fir, is a turpentine which is made from the resin of the balsam fir tree (Abies balsamea) of boreal North America.

 +"Canada balsam comprises about 55% of diterpenoid acids, mainly abietic, neoabietic and
 +palustric acids, 26% of volatile terpene hydrocarbons and about 19% of neutral diterpenoids
 +of which the larger part consists of [[https://www.thegoodscentscompany.com/data/rw1491571.html|abienol]]." \\

 Steam distillation of foliage from Abies balsamea yielded 0.59% of an essential oil. Components were β-pinene (36%), bornyl acetate (14%), Δ3-carene (11%), limonene (11%), α-pinene (8%), camphene (6%), myrcene (2%), santene (1%), tricyclene (1%) and camphor, borneol, d-canadene, bisabolene, and terpinolene (all below 1%). \\ Steam distillation of foliage from Abies balsamea yielded 0.59% of an essential oil.
