In cold-temperate ecosystems of the upper Great Lakes Region, evergreen conifer-dominated forests were once common. As a result of past management practices, early-successional deciduous forests now dominate the landscape. Embedded in this matrix are stands of shade-tolerant conifers, including Thuja occidentalis . For the past several decades, large-scale T. occidentalis regeneration in remnan...

Volatile com pounds which are released from fresh leaves o f Thuja occidentalis inhibited ger­ m ination o f seeds o f Amaranthus caudatus and Lepidium sativum. The volatile com pounds were obtained by a vacuum m ethod applied to the leaves, by direct analysis o f the content o f secretory organs and by solvent extraction o f leaves. The bioactive com pounds proved to be m onoterpenes. The high...

Leaves & twigs, which contains essential oil, condylomatous growth, spongy tumours, warts, ill effects of vaccination etc. Twigs fan-shaped; leaves ovate, obtuse, having resin ducts & parenchymatous mesophyll; stem shows resins ducts in parenchymatous cortex...

the methanolic leaf extract of thuja occidentalis was evaluated for possible sedative activities in mice. sedative activity was evaluated by using hole cross, open field, thiopental sodium-induced sleeping time and elevated-plus maze (epm) tests at 200mg/kg and 400 mg/kg.  the extract decreased the locomotor activity of mice in hole cross, open field and epm test and showed the remarkable resul...

Papillomatosis is a condition in farm animals and is treated by surgical excision or application of certain caustic agents. Contrary to it, two cattle with teat warts were treated by an alternative method by using the thuja occidentalis (thuja-30, a homeopathic medicine) @ 10 drops Per os twice a day for a span of 3 weeks and lead to complete recovery.

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...

The adverse side-effects associated with chemotherapy during cancer treatment have shifted considerable focus towards therapies that are targeted but devoid of toxic side-effects. In the present study, the antitumorigenic activity of thuja, the bioactive derivative of the medicinal plant Thuja occidentalis, was evaluated, and the molecular mechanisms underlying thuja-induced apoptosis of functi...
