The invention discloses a veterinary drug for treatment of duck virus hepatitis, which consists of components in part by weight: 15-45 parts of radix isatidis, 9-15 parts of scutellaria root, 30-90 parts of oriental wormwood, 9-15 parts of rheum officinale, 15-30 parts of cape jasmine, 6-15 parts of caulis clematidis armandii, 9-24 parts of semen plantaginis and 9-21 parts of felwort. The veterinary drug for treatment of duck virus hepatitis is prepared based on the traditional Chinese veterinary theory. According to the traditional Chinese veterinary theory, duck virus hepatitis refers to dampness-heat of the liver and gallbladder caused by exogenous viruses and gallbladder and diarrhea resulting from damp heat. Wind can be caused by extreme heat, thereby resulting wind agitation in the liver, i.e. coma, spasms, convulsions, diarrhea and other symptoms in clinical manifestations. When the drug is applied in treatment, heat can be cleared away, toxicity can be removed, the liver can be soothed, depression can be relieved, wind and spasms can be avoided, and the stagnation can be relieved.
