Embodiment 1
[0033] (1) a kind of Chinese medicine for the treatment of rhinitis, is formed by the proportioning of following crude drugs by weight:
[0034] 30 parts of big black claw golden dragon, 25 parts of calla lily, 20 parts of chrysanthemum brain, 15 parts of loofah brain, 15 parts of flat cattail fan, 10 parts of asarum, 10 parts of cassia seed, 10 parts of typhoid grass, 10 parts of mountain magnolia flower, 5 parts of honeycomb 5 parts, 5 parts of Astragalus.
[0035] (2) Preparation method:
[0036] In the first step, calla lily and chrysanthemum brain are mixed in proportion, extracted twice with n-propanol having an alcohol concentration of 70% equivalent to twice the mass of the mixture, and the filtrates are combined, concentrated under reduced pressure, dried and pulverized into powder, and then used Purify 1-2 times 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 ...
Embodiment 2
[0041] (1) A kind of Chinese medicine for the treatment of rhinitis is formed by the proportioning of following crude drugs by weight: same as embodiment 1.
[0042] (2) Preparation method:
[0043] In the first step, calla lily and chrysanthemum brain are mixed in proportion, extracted twice with n-propanol having an alcohol concentration of 70% equivalent to twice the mass of the mixture, and the filtrates are combined, concentrated under reduced pressure, dried and pulverized into powder, and then used 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;
[0044] In the second step, the loofah brain, flat cattail fan, asarum, and cassia seeds are extracted twice with n-propanol with an alcohol concentration of 80%, the extracts are combined, concentrated under reduced pressure, dried, and pulverized into powder, and the pulverized powder is...
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...
