Embodiment 1

[0016] Take 4800g of Forsythia and 4800g of Houttuynia cordata, mix well, heat and reflux with 8 times of 75% ethanol for 2 times, 1 hour each time, filter, combine the filtrate, and concentrate the filtrate under reduced pressure to a relative density of 1.05~1.15 (50 ℃), refrigerate, take the supernatant and extract 4 times with 4 times the amount of water-saturated n-butanol, combine the n-butanol solution, recover the n-butanol under reduced pressure, and dry the concentrated solution in vacuum at 65°C to obtain forsythia and Houttuynia cordata mixed extract. Take the above extract, add 2500ml of water, stir and dissolve, the solution is refrigerated at 4°C for 24 hours, the supernatant is filtered with a 0.45um filter membrane, the solution is concentrated under reduced pressure and vacuum dried at 65°C to obtain a dry paste. Dissolve the dry ointment with 2000ml of water for injection, add 45g of mannitol for injection, adjust the pH to 6.0-8.0 with 40% sodium hydroxide solu...

Embodiment 2

[0018] Take 5100g of Forsythia and 5100g of Houttuynia cordata, mix well, heat and reflux with 9 times 70% ethanol for 2 times for 1.5 hours each time, filter, combine the filtrate, and concentrate the filtrate under reduced pressure to a relative density of 1.05~1.15 (50 ℃), refrigerate, take the supernatant and extract 5 times with 6 times the amount of water-saturated n-butanol, combine the n-butanol solution, recover the n-butanol under reduced pressure, and dry the concentrated solution in vacuum at 65°C to obtain Forsythia and Houttuynia cordata mixed extract.

Description

Technical field [0001] The invention relates to a medicine for treating acute exogenous fever, in particular to a Chinese patent medicine prepared by using Chinese herbal medicine as a raw material. The invention also relates to a preparation method of the medicine. Background technique [0002] Wind-warming lung-heat is an acute exogenous fever with fever, cough, and expectoration as the main clinical manifestations, which are common in all seasons caused by the feeling of wind-heat disease, but frequently occur in winter and spring. From the perspective of clinical manifestations, acute lung infections equivalent to acute pneumonia, peribronchitis, and acute bronchitis in Western medicine 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 affect people's health, and the mortality rate of lung infections caused ...
