Thuja occidentalis, commonly known as eastern white cedar or arborvitae, is a species of coniferous tree native to eastern North America. The name "Thuja" is derived from a Greek word meaning "to fumigate" or "to sacrifice," referring to the tree's historical use in purification rituals. In Hebrew, it is known as תויה מערבית (Thuya ma'aravit). Other relevant translations include Lebensbaum in German, cèdre blanc in French, and tuya occidental in Spanish. This evergreen tree is characterized by its narrow, scale-like leaves and small, inconspicuous cones. It is widely cultivated as an ornamental plant and is also valued for its timber, which is resistant to decay and often used in outdoor construction. Additionally, Thuja occidentalis has been used in traditional medicine for its purported health benefits, although scientific evidence supporting these uses is limited.
