The objects of study were coniferous plants aged from 6 to 10 years. involved such as Siberian spruce (Pícea obováta), prickly Hoopsi (Picea pungens Hoopsii), western thuja Smaragd (Thuja occidentalis Smaragd), Brabant Brabant). subject the was pathological symptoms manifested on aboveground plant organs. planted in 2015 at age (thuja and Brabant) (prickly spruce) studies conducted May 2016 Sep...

A Sahiwal breed heifer calf of ~ 5-month age was presented with numerous warts varying sizes principally on head, face and neck. The history clinical examination were suggestive bovine cutaneous papillomatosis. animal treated medically an alternative medicine: Thuja occidentalis 30X. regressed completely after two months treatment occidentalis, suggesting this medicine can be used to treat in b...

Various mitogens have been described which act on different subpopulations of mouse and/or human peripheral lymphocytes. In recent years it has been mainly Japanese and German research teams that have isolated polysaccharide fractions with immunomodulative properties [1-3, 17]. In addition to fungal polysaccharides such as lentinan, schizophyllan, and PSK polysaccharide, which are basically in ...

—Northern white cedar (Thuja occidentalis L.) stands throughout the upper Midwestern United States have failed to recruit individuals to the canopy consistently for several decades. To examine local and landscape factors that influence cedar regeneration we recorded the abundance of cedar seedlings and saplings in 24 lowland cedar stands in the Chequamegon-Nicolet National Forest, Wisconsin, du...

MCCUNE, B., and T. F. H. ALLEN. 1985. Will similar forests develop on similar sites? Can. J. Bot. 63: 367-376. Abies grandis, Taxus brevifolia, Thuja plicata, or any combination of these may dominate old-growth mesic forests of the Bitterroot Canyons, western Montana. Similar sites need not develop similar, relatively stable forests. This is shown by (i) anomalous distributional patterns of tre...

Regeneration success of canopy dominants is linked to multiple factors, including the ability of their seedlings to survive browsing and to utilize available resources in the understory. In remnant upland northern white cedar Thuja occidentalis L. forests, e€ects of browsing on recruitment of cedar seedlings were evaluated at 7 sites, including known deer yards, located on a portion of the Lake...

Essential oils have insecticidal activity against several insects and are composed of numerous compounds. This study investigated the effects Thuja occidentalis L. (Cupressaceae) essential oil, terpinyl acetate, bornyl acetate peach aphid [Myzus persicae (Sulzer)]. The effect on three Cupressaceae plants was highest in T. occidentalis. oil extracted by steam distillation, optimum conditions wer...

We examined the extent of osmotic adjustment and the changes in relative water content (RWC) and transpiration rate (i.e., relative stomatal function) that occur in water-deficit-conditioned 6-year-old Thuja occidentalis L. (eastern white cedar) trees in response to a severe drought. Trees conditioned by successive cycles of mild or moderate nonlethal water stress (conditioning) and nonconditio...

We investigated the extent of osmotic adjustment and changes in transpiration rate that occur in response to repeated cycles of water deficit stress in 6-year-old Thuja occidentalis L. (eastern white cedar) trees. Groups of trees were water-stress conditioned by repeated exposure to predetermined thresholds of nonlethal water stress by withholding water until the predawn water potential fell to...

Arbor vitae (Thuja occidentalis L.) is a native European tree widely used in homeopathy and evidence-based phytotherapy. Many reviews and monographs have been published on the herbal substance's description, mode of action and clinical use. However, no comprehensive evidence-based review is available. Therefore, our aim was to search MEDLINE databases and survey manufacturers for further detail...
