| "Incense-cedar also is used extensively for exterior siding because it is dimensionally stable and holds paint well, in addition to being durable. Rich color, sound knots, and aromatic fragrance make the wood popular for interior paneling and woodwork... Incense-cedar is ideally suited to the manufacture of pencils because it is soft, easily whittled, and has straight grain. Much of the top-grade lumber produced goes to this use." [U.S. Forest Service Silvics Manual] [[http://www.na.fs.fed.us/pubs/silvics_manual/Volume_1/libocedrus/decurrens.htm]] | "Incense-cedar also is used extensively for exterior siding because it is dimensionally stable and holds paint well, in addition to being durable.

| Steam distillation of C.decurrens heartwood gave 0.6% of an essential oil composed mainly of p-cymene and p-menthane derivatives. Thymoquinone (35.9%), carvacrol (29.2%), p-methoxythymol 11% and p-methoxycarvacrol 3.2% were the main components. "The tropolone [[http://www.thegoodscentscompany.com/data/rw1044801.html|beta-thujaplicin]] (hinokitiol) was only present in trace amounts. The high concentrations of thymoquinone and carvacrol alone can account for the previously observed high bioactivity of this oil. Carvacrol is well known for its antimicrobial, antioxidant, insecticidal, and repellent activities." \\ | Steam distillation of C.decurrens heartwood gave 0.6% of an essential oil composed mainly of p-cymene and p-menthane derivatives.
