CHAVES, Thaís Castelo Branco et al. Thuja occidentalis ineficiency in avian poxviruses treatment. Cienc. Rural [online]. 2006, vol.36, n.4, pp. 1334-1336. ISSN 1678-4596. http://dx.doi.org/10.1590/S0103-84782006000400050.
Arbor Vitae (Thuja occidentalis) is widely used in homoeopathic and phytotherapic treatments,either for human or for animals. Its immunestimulating and antiviral properties have been described and its empiric use in the treatment of the avian poxvirosis is recommended by animal breeders and veterinarians. To evaluate the therapeutic potential of Arbor Vitae in these infections, two groups (control and test) of 10 young birds were inoculated by scarification with a field sample of avian poxvirus. When lesions were first observed the test group received the Arbor Vitae alcoholic extract diluted in the drinking water. The birds were examined daily, from the beginning and evolution of the lesions to the healing. The results indicated that, in our experimental conditions, the use of T. occidentalis did not favor the regression or restriction in the development of the skin lesions promoted by the experimental infection.
