Thuja occidentalis is a homeopathic medicine prepared from the Northern White Cedar or Arborvitae, Thuja occidentalis (Cupressaceae). It is an evergreen coniferous tree native to Eastern Canada and the Northeastern United States.
Homeopathic medicines containing Thuja occidentalis have been used for centuries by people suffering from symptoms associated with scurvy, psoriasis, and bronchitis. Its essential oil has also been used in cleansers, insecticides, and soaps. The process of preparing the homeopathic medicine Thuja occidentalis involves significantly diluting its plant-based raw material, the Northern White Cedar.
