Thuja (Thuja occidentalis), also known as Northern White Cedar or Arborvitae, is a tree native to eastern North America. Indigenous peoples used various parts of the tree for medicinal and ceremonial purposes.

The name “Arborvitae” means “tree of life,” reflecting its historical importance. The leaves and bark were used to treat respiratory infections, fever, and rheumatism. European settlers adopted these uses and also employed thuja as an ornamental tree.

Thuja contains compounds such as thujone, which has antifungal, antiviral, and antibacterial properties.

In modern herbal medicine, thuja is used to support the immune system, treat warts, and alleviate respiratory conditions.
