Abstract

A Chinese medicine in the form of injection for treating acute lung infection, such as acute pneumonia and peribronchitis, cold, cough, etc is prepared from railway beggarticks herb and scutellaria root. Its advantage is high curative effect.

Description

Technical field [0001] The invention relates to a medicine for treating acute pulmonary infection, in particular to a Chinese patent medicine prepared from Chinese herbal medicine, and also relates to a preparation method of the medicine. Background technique [0002] Wind-warm lung-heat is an acute exogenous febrile disease with fever, cough, and expectoration as the main clinical manifestations. From the perspective of clinical manifestations, it is equivalent to acute lung infection diseases such as acute pneumonia, peribronchitis and acute bronchitis in Western medicine, which are common clinical diseases and frequently-occurring diseases. At present, antibiotics are clinically effective in treating bacterial pneumonia, but pneumonia caused by viruses and drug-resistant strains still seriously affects people's health, and the mortality rate of lung infections caused by Gram-negative bacteria is still as high as about 50%. [0003] Pulmonary infection accounts for a larg...
