| "Thujopsis dolabrata is monoecious, with seed cones and pollen cones occurring on the same plant. Both types of cones grow terminal on branches, and do not exceed a few centimeters in length... Thujopsis dolabrata is used mainly for ornamental purposes. In Japan, it was once considered a sacred tree. Today, Thujopsis dolabrata can still be found as a decorative tree adorning the gardens of Japanese temples."

| "Thujopsis dolabrata differs from Incense Cedar and Red Cedar as it has wider flatter branches and visible stomata. Cone shape is also quite variable, tending to be globular more than flask-like. Like other cedars and Cedrus, the bark is shreddy and scented."

| "The steam distillate of the Thujopsis sawdust was shown to have potent antignawing activity. Three terpenoid compounds with antignawing activity were isolated from the steam distillate of the Thujopsis sawdust: thujopsene, carvacrol, and β-thujaplicine. Carvacrol exhibited the most potent repellent activity. As a naturally occurring repellent, carvacrol could be useful as new preventive agent against various kinds of damage caused by rodents." \\ | "The steam distillate of the Thujopsis sawdust was shown to have potent antignawing activity.

This compound is nothing more than a compound with the acetyl group, instead of the isopropyl group, at the 4-position of hinokitiol. Hinokitiol, the major component (1.0%) of this plant, has already been found to show the antimicrobial activity, inhibitory activity on metalloproteases or catechol-O-methyltransferase, insecticidal activity, cytotoxic effect on mammalian tumor cells and phytogrowth-inhibitory activity. We previously reported that β-dolabrin and γ-thujaplicin, like hinokitiol, had a phytogrowth-inhibitory effect, inhibited metalloproteases, and had an antimicrobial activity and a cytotoxic effect on mammalian tumor cell lines. It has been reported that three compounds showed insecticidal activity against Tyrophagus putrescentiae and Coptotermes formosanus and antifungal activity on wood-rotting fungi. α-Thujaplicin, another minor component of the plant, exhibited the antibacterial activity, phytogrowth-inhibitory effect, metalloprotease inhibition and cytotoxic effect on mammalian tumor cell lines." \\ | with chlorophyll biosynthesis inhibition, cytotoxic effect and inhibitory activity on metalloproteases...

| Hinokitiol (β-thujaplicin) "...can restore site- and direction-selective iron transport in different cells deficient in three distinct iron-transport proteins, and the same compound can promote dietary gut iron absorption or peripheral hemoglobinization in corresponding animal models. Mechanistic studies support the role of transmembrane ion gradients that build up in the setting of missing iron transporters, enabling hinokitiol to restore site- and direction-selective transmembrane iron transport. Further, endogenous protein-based homeostatic mechanisms interface with this imperfect small molecule to promote iron-related physiological processes without disrupting other cellular processes." \\ | Hinokitiol (β-thujaplicin) "...can restore site- and direction-selective iron transport in different cells deficient in three distinct iron-transport proteins, and the same compound can promote dietary gut iron absorption or peripheral hemoglobinization in corresponding animal models.
