THUJA Overview Information

Thuja is a tree. The leaves and leaf oil are used as a medicine.

Thuja is used for respiratory tract infections such as bronchitis, bacterial skin infections, and cold sores. It is also used for painful conditions including osteoarthritis and a nerve disorder that affects the face called trigeminal neuralgia.

Some people use thuja to loosen phlegm (as an expectorant), to boost the immune system (as an immunostimulant), and to increase urine flow (as a diuretic). It has also been used to cause abortions.

Thuja is sometimes applied directly to the skin for joint pain, ostearthritis, and muscle pain. Thuja oil is also used for skin diseases, warts, and cancer; and as an insect repellent.

In foods and beverages, thuja is used as a flavoring agent.

In manufacturing, thuja is used as a fragrance in cosmetics and soaps.
