Thuja
Thuja
Thuja (pronounced /ˈθjuːdʒə/), also known as arborvitae (from Latin for 'tree of life'), is a genus of coniferous trees in the Cupressaceae (cypress family). The name Thuja is a Latinized form of a Greek word meaning 'to fumigate,' or 'to sacrifice,' referring to the strong aroma released by these trees when they are burned.
Etymology
The name Thuja originates from the Greek word 'θυία', which refers to an African tree with sweet-smelling wood. The term was later Latinized to 'Thuja', which is now used to refer to this genus of trees. The common name, arborvitae, is derived from Latin and translates to 'tree of life', due to the medicinal properties attributed to these trees.

There are five species in the Thuja genus:
- Thuja occidentalis - Eastern Arborvitae, Northern White-cedar

Each species has its own unique characteristics and habitat preferences.

The Thuja genus has been used in traditional medicine for centuries. The leaves and twigs of Thuja occidentalis are used in herbal medicine as a diuretic and expectorant, and to stimulate the immune system. The oil from the leaves has been used topically for warts, ringworm, and thrush.
