Description

technical field [0001] The invention relates to a traditional Chinese medicine composition for preventing and treating avian influenza, and also relates to a preparation method of the traditional Chinese medicine composition. Background technique [0002] Avian influenza (Avian Influenza, AI) is an infection and / or disease syndrome of birds (poultry and wild birds) caused by influenza A virus of the family Orthomyxoviridae. It mainly occurs in poultry and birds such as chickens, ducks, geese, and pigeons, but it mainly affects turkeys and chickens. Mammals such as pigs, horses, seals, and humans can also be infected. According to the pathogenicity of avian influenza virus (Avian InfluenzaVirus, AIV) strains, the type of poultry, the environment, feeding and management conditions, concurrent diseases and other factors, the infected poultry showed asymptomatic infection, mild upper respiratory symptoms, childbirth, etc. The reduction of egg volume to acute pathogenic death an...
