Northern White Cedar

Thuja occidentalis

Northern white cedar carries one of the most famous survival stories in botanical history. In 1536, Jacques Cartier's crew, stranded and dying of scurvy along the St. Lawrence River, was taught by the Iroquois to brew the needles into a drink that saved dozens of lives. Cartier is said to have named the tree arbor vitae, tree of life, in gratitude. Beyond that winter, various Indigenous nations of the northeast used the wood for canoe frames, baskets, and lodge poles, and applied the crushed foliage externally to the skin. Because the tree is rich in thujone, a compound that is toxic when ingested in any real quantity, its story belongs more to craft, shelter, and topical folk use than to the tea kettle.

Safety.

Northern white cedar is toxic if ingested and should never be taken internally as a tea, tincture, or supplement in any home setting. Its foliage and essential oil contain thujone, a compound that can cause seizures, vomiting, kidney and liver damage, and in significant doses has been fatal. The plant has a dark historical use as a folk abortifacient, and that use has caused serious harm and death; it must never be used for this or any internal purpose, especially during pregnancy. It is also toxic to pets and livestock if browsed or chewed in quantity. Any topical, homeopathic, or professionally prepared form of thuja should only be used under the direct guidance of a qualified, licensed healthcare provider or herbalist who can assess safe, appropriate use, and anyone considering it for any reason should speak with a doctor first.
