Thuja occidentalis

Cedar leaf oil (Thuja oil) is produced by steam distillation of fresh leaves and branch ends of the tree Thuja occidentalis L. (Cupressaceae). It is a colorless to yellow liquid with a powerful, herbaceous odor, characteristic of thujone, see p. 217, [314-319a].

Cyclopentane bicyclic monoterpenoids that occur in the plant kingdom belong to three major skeletal types camphane, iso-camphane, and fenchane (Fig. 7). Camphane-type terpenoid alcohols, (+)-bomeol (Gl) and (—)-isobomeol (G2), have been isolated from Cinnamomum camphora (Lauraceae) and Achillea filipendulina (Asteraceae). A ketone derived from these, (-h)-camphor (G3), is found in the camphor tree Cinnamomum camphora) and in the leaves of rosemary Rosmarinus officinalis) and sage Salvia officinalis, Labiatae). Camphene (G4) and its enantiomer with the isocamphane carbon skeleton are known to occur in the oils of citronella and turpentine. Fenchane-type bicyclic cyclopentane monoterpenoids are commonly found in plants as their ketone derivatives. (—)-Fenchone (G5) occurs in the tree of life Thuja occidentalis, Cupres-saceae). Its enantiomer, (+)-fenchone (G6), has been isolated from the oil of fennel Foeniculum vulgare, Umbelliferae).

Thujae occidentalis herb, Baptisiae tinctoriae root, E. purpurea root, and E. pallida root, were given to mice. After 6 days the mice were inoculated with Influenza virus Type A. They found a statistically significant increase in survival rate, survival time, reduced lung consolidation, and virus titer (14).

Oil of Cedar Leaf. Cedar leaf oil. Obtained by steam distillation from the fresh leaves of Thuja occidentalis L, Cupressaceae.

Thuja occidentalis is, as its common name says, endemic to North America Thuja orientalis to China. Both plants, however, are widely spread now worldwide as ornamental plants. There is no difference in the composition of their terpenes. The main component, also responsible for the toxicity is thujon with more than 50 per cent of the essential oil from Thuja. Furthermore fenchone, campher, sabinene, and terpineol-4, tannins and bitter principles are found, too.
