Abstract: This invention is directed to oral botanical compositions comprising plant extracts, methods of preparing the same, and methods of using the same for treating an infection.

Abstract: The invention provides a method for imparting resistance in animals to viruses, and in plants to viruses and viroids, that express double-stranded RNA-like structures (dsRNAs). This method enables the binding of pathogenic dsRNAs during the infection process by expression of dsRNA-binding protein in transgenic animal and plant hosts, thus interrupting the infection cycle and inhibiting disease. The presence of a dsRNA-binding protein in a transgenic host renders the transgenic host resistant to the phenotypic symptoms of viral infection and/or decreased pathogen replication. Accordingly, the present invention provides a genetically engineered animal and plant, stably transformed to express a dsRNA-binding protein, such that the transgenic host displays resistance to virus and/or viroid challenge.
