Embodiment 1
[0033] (1) A Chinese medicine for treating asthma, which is formed by proportioning the following raw materials by weight:
[0034] 30 parts of white green leaves, 25 parts of japonicus root, 20 parts of Baiyan vine, 15 parts of black shell nan, 15 parts of gourd leaves, 10 parts of thyme, 10 parts of sansevieria, 10 parts of white flower gentian, 10 parts of Cymbidium, golden flower grass 5 copies, 5 copies of Big Tail Shake.
[0035] (2) Preparation method:
[0036] In the first step, japonicus japonicus and japonicus japonicus are mixed in proportion, extracted twice with n-propanol whose alcohol concentration is 70% which is equivalent to twice the mass of the mixture, combined the filtrates, concentrated under reduced pressure, dried and pulverized into powder, Then purify with ethanol for 1-2 times, combine the extracts, recover the ethanol under reduced pressure and concentrate to a paste with a relative density of 1.21-1.24 at 60°C, dry and pulverize into powder;

Embodiment 2
[0041] (1) a kind of Chinese medicine for the treatment of asthma, is formed by the proportioning of following crude drug by weight: Same as embodiment 1.
[0042] (2) Preparation method:
[0043] In the first step, japonicus japonicus and japonicus japonicus are mixed in proportion, extracted twice with n-propanol whose alcohol concentration is 70% which is equivalent to twice the mass of the mixture, combined the filtrates, concentrated under reduced pressure, dried and pulverized into powder, Then purify once with ethanol, combine the extracts, recover ethanol under reduced pressure and concentrate to a paste with a relative density of 1.21-1.24 at 60°C, dry and pulverize into powder;

Embodiment 3
[0048] 1. Long-term toxicity test process:
[0049] Apply Wistar rats (Beijing Weitong Lihua Experimental Animal Technology Co., Ltd. provides) experimental medicine is set to high, medium and low three dosages, be respectively the capsule 8g / kg, 4g / kg, 2g of embodiment 1 formula / kg. Calculated according to the human dose of 0.1g / kg / day tablet, it is 80 times, 40 times and 20 times of the effective dose for human respectively; another control group is set up, which is given continuously for 90 days and 180 days by intragastric administration and part of the animals are withdrawn for 10 days. Days later, the effects on various physiological and biochemical indicators of rats were observed. The experimental results show that: continuous oral administration of different doses to rats for 180 days has no effect on the food intake and weight growth of the rats. No significant toxic effects were found on liver and kidney function. There was no obvious effect on blood routine, bl...
