Compound traditional Chinese medicine for effectively preventing and controlling H1N1 and H3N2 swine influenza and porcine reproductive and respiratory syndrome, and preparation method thereof

Abstract

The present invention discloses a compound traditional Chinese medicine for effectively preventing and controlling H1N1 and H3N2 swine influenza and porcine reproductive and respiratory syndrome, wherein the types and the contents of the traditional Chinese medicines in the compound traditional Chinese medicine are provided. The compound traditional Chinese medicine comprises, by weight, 20 parts of ephedra sinica stapf, 20 parts of scutellaria baicalensis, 9 parts of rhizoma anemarrhenae, 9 parts of bulbus fritillariae cirrhosae, 9 parts of apricot kernel, 9 parts of herba houttuyniae, 9 parts of morus alba l, 9 parts of rheum palmatum l, and 6 parts of licorice root. The invention further provides a preparation method of the compound traditional Chinese medicine. The preparation method comprises: weighing the raw materials according to the weight part ratio to obtain 100 g of the compound traditional Chinese medicine, crushing to achieve 20 mesh, and soaking for 1 h; carrying out water decocting 2 times, wherein the boiling time is 30 min every time; merging the two decocting liquids; and carrying out normal pressure vacuum suction filtration and concentration, carrying out volume metering to achieve 100 mL of the water decocting liquid, carrying out high pressure sterilization on the water decocting liquid, and storing in a 4 DEG C refrigerator so as to be spare. According to the present invention, the in vivo and in vitro test results prove that the compound traditional Chinese medicine preparation can effectively prevent and control H1N1 and H3N2 swine influenza and porcine reproductive and respiratory syndrome.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine for veterinary use, and relates to a traditional Chinese medicine compound for effectively preventing and treating H1N1 and H3N2 swine flu and pig blue-ear disease and a preparation method thereof. Background technique [0002] Swine influenza (swine influenza, SI), also known as swine influenza, is an acute, febrile, highly contagious respiratory disease caused by swine influenza virus (swine influenza virus, SIV) of the family Orthomyxoviridae.

The disease occurs all over the world, causing serious harm, huge economic losses, and a threat to human health. Its prominent epidemic feature is that it often exists in a subclinical form and often causes secondary or mixed infections of other respiratory bacteria and viruses, such as porcine rep...

AI Technical Summary

Problems solved by technology

[0005] Looking at the current experimental research on the anti-virus of traditional Chinese medicine compounds, there are many studies on single prescriptions against swine influenza virus and porcine reproductive and respiratory syndrome virus (or "porcine blue ear disease"). At present, no compound prescription has been developed that can simultaneously Anti-swine influenza virus and porcine reproductive and respiratory syndrome virus

Moreover, most of them are independently studied by in vivo test or in vitro test, which cannot comprehensively evaluate the effect of traditional Chinese medicine compound against swine influenza virus and porcine reproductive and respiratory syndrome virus.
