Thuja Occidentalis Leaf, also known as Northern White Cedar or Arborvitae, is derived from the dried, cut leaves of the Thuja tree, scientifically named Thuja occidentalis L., which belongs to the Cupressaceae family. This evergreen tree is native to North America and is commonly found in the northeastern United States and southeastern Canada. The leaves are rich in essential oils, flavonoids, and tannins, which contribute to their beneficial properties.
