Spray agent for preventing and treating avian influenza and preparation method of spray agent

Abstract

The invention relates to a spray agent for preventing and treating avian influenza and a preparation method of the spray agent. The spray agent is prepared from periplaneta americana, radix isatidis, fructus forsythiae and folium isatidis according to certain proportions by extracting and concentrating. The spray agent also has functions of clearing away heat and removing toxic materials, resisting inflammation and boosting immunity. Based upon experimental contrast, the spray agent is significant in an effect on preventing and treating the avian influenza disease, wherein the total effective rate of treating the avian influenza disease can reach 98%. The production process of the spray agent is simple and low in cost; the spray agent, when used in vitro, can avoid the influence of liver and renal damage caused by long-term use; and the spray agent is suitable for large-scale popularization and application.

Description

technical field [0001] The invention belongs to the field of traditional Chinese medicine preparations, in particular to a spray medicament for preventing and treating bird flu and a preparation method thereof. Background technique [0002] Avian influenza is the abbreviation of avian influenza. It is an infectious disease caused by a subtype of influenza A virus (also known as avian influenza virus). Chickens, ducks, geese and wild birds, waterfowl, seabirds , people, etc. can be infected. According to the different types of pathogens, avian influenza can be divided into three categories: highly pathogenic, low pathogenic and non-pathogenic avian influenza: non-pathogenic avian influenza does not cause obvious symptoms, and only causes infection in the body of infected birds. produce antiviral body; low pathogenic avian influenza can cause mild respiratory symptoms, reduced food intake, decreased egg production, and sporadic death in poultry; highly pathogenic avian influe...

AI Technical Summary

Problems solved by technology

[0003] At present, if poultry are found to be suffering from highly pathogenic avian influenza, a comprehensive measure of strict isolation and blockade and culling of the whole group is basically adopted. Although this can suppress the spread of the virus, it will undoubtedly cause huge economic losses to the poultry breeding industry. Loss; for the prevention and treatment of avian influenza, Western medicine mainly injects or feeds antibiotics, antiviral or hormone drugs in clinic. , which limits its clinical application

There are also Chinese patent medicines for the prevention and treatment of avian influenza in the market now. Among them, there are many raw materials in the medicine, which makes the preparation process complicated, and the finished medicine is absorbed slowly after taking it, and the virus inhibition effect is not obvious, and the treatment effect is not ideal. In addition, the existing Chinese patent medicines basically treat avian influenza by mixing with feed or drinking water, and taking it for a long time will cause certain damage to the liver and kidney of poultry, seriously affecting the quality of poultry meat, which will also Corresponding losses to the poultry farming industry
