 +"The essential oil of balsam fir... [needles] is rich in monoterpenes, more than 95%. The dominant monoterpenes... are β-pinene (B), typically around 25-35%, and Δ3-carene (C) at 8-20% (with exceptions, see below). Some oxygenated compounds of this oil are bornyl acetate (F) typically between 5% and 9%, α-terpineol (D) between 0,1% and 1%, piperitone (E) between ∽0,1% and 1,2% and thymol (G) between traces and 0,3%..." \\
