Canoe Cedar
Thuja plicata
Thuja plicata, commonly known as western redcedar, is a coniferous tree native to North America. While traditional medicinal uses for this plant are not well-documented, it has been studied in various contexts. Scientific evidence indicates that the arbuscular mycorrhizal fungal communities associated with Thuja plicata show some overlap with those of Taxus brevifolia, suggesting potential ecological interactions. Additionally, Thuja plicata demonstrates varying degrees of resistance to wood decay fungi, though the exact mechanisms are not fully understood. Fire intensity significantly impacts sapling mortality; however, observed mortality is lower than predicted models at low intensities. A recombinant protein from Thuja plicata has been shown to reduce one furan ring of (+)-pinoresinol to produce (-)-secoisolariciresinol, indicating potential chemical activity but no clear medicinal applications are known. No major safety issues or drug interactions have been recorded for this plant.

What the science says
- The study found that western redcedar showed varying degrees of resistance to eight wood decay fungi, with some pathogens causing visible symptoms while others resulted in latent infections.
- The arbuscular mycorrhizal fungal communities associated with Taxus brevifolia showed high overlap and were influenced by rhizosphere soil pH and neighboring tree species.
- The probability of mortality in Thuja plicata saplings increases with fire intensity but shows lower observed mortality than predicted models at low fire radiative energy dosages.
- A recombinant PLR from Thuja plicata preferentially reduces one furan ring of (+)-pinoresinol to produce (-)-secoisolariciresinol.
