Thuja occidentalis (Western red cedar)) and Thuja orientalis belong to the Cupressaceae family, they are evergreen trees originating from North America and East Asia.
Thuja is an oil used in alternative medicine and phytotherapy to treat scurvy, cystitis, rheumatism, cancer.
One of its components, alpha-thujone, a monoterpene that can easily penetrate the blood-brain barrier, has shown positive therapeutic effects against cancer. Alfa-thujone exerts proapoptotic and anti-invasive effects on cells confirming the potential for the treatment of glioblastoma multiforme (1).
In the essential oil of Thuja occidentalis there are terpenes such as Alpha-pinene, alpha cedrol, terpinolene, limonene (2).
In this study, leaf extract from Thuja orientalis showed a clear inhibition of angiogenesis in vivo and in vitro in lung cancer cells, thus demonstrating anti-cancer properties (3).
It is used in cosmetics and body cleansers.
