Abstract: Mulberry leaves and Eucommia ulmoides are commonly used traditional Chinese medicines with high medicinal value. As an immunopotentiator for veterinary use, the Sangdu oral liquid, a compound prescription prepared with mulberry leaves and Eucommia ulmoides, can effectively enhance the immunity of animals. The in-depth study on the effective components of Sangdu oral liquid, such as flavonoids, amino acids and polysaccharides, may provide a scientific basis for the development of new type traditional Chinese veterinary medicine.
