[0067] The preparation method includes the following steps:
[0068] (1) weight ratio weighed cork, forsythia, honeysuckle, dandelion and centipedes, extracted three times with boiling water; the first one hour, the second 45 minutes, the third 30 minutes;
[0069] (2) decoctions were combined, filtered and the filtrate concentrated to a clear paste relative density of 1.10;
[0070] (3) Ethanol was added, and the ethanol content was 70%, allowed to stand for 24 hours, filtered, the filtrate was concentrated to a mixed alcohol, and the liquid is obtained;
[0071] (4) Add the liquid obtained from step (3) to 1000 parts by weight, stir well, stand, refrigerated for 24 hours, filtered, filling, sterilizing,
Embodiment 1
[0072] Fang Huangbo liquid varnish complex toxicity to normal mice: Example 1
[0073] 1. Experimental animals:
[0074] Clean grade 8-week-old adult female C57 / BL6 mice, weighing 19-21 grams, Jinan Peng Yue provided by a laboratory animal breeding Co., animal certificate number: SYXK (Lu) 20200022.
[0075] 2, experimental groups:
[0076] After the animals adapt to the environment for one week, they were randomly divided into two groups weighed, i.e., control group and the administered group, n = 8.
[0077] 3, the method of administration:
[0078] PM administered mice and the control group mice were administered daily intraperitoneal injections administered group was 3-fold concentrated solution primer complex Fang Huangbo administration ratio 0.3mL / 20g body weight by continuous administration of 21 days, the control group with the administration time and route of administration group consistent with PBS buffer instead of the drug.

[0092] Example 2: EPO complex Fang Huangbo liquid varnish on myeloproliferative tumors high Induced polycythemia vera treatment of experimental disease
[0093] 1. Experimental animals:
[0094] Clean grade 8-week-old adult female C57 / BL6 mice, weighing 19-21 grams, is provided by Jinan Peng Yue experimental animal breeding Co., animal certificate number: SYXK (Lu) 20200022.
[0095] 2, experimental groups:
[0096] After the animals adapt to the environment for one week, weighed and then randomized into three groups, normal control group, model group and the administration model group, n = 8.
[0097] 3, polycythemia vera model method:
[0098] Using EPO high The mouse model of polycythemia vera.
[0099] EPO high Model as follows: mice were injected intraperitoneal injection of recombinant human erythropoietin, 5000UI / kg, injected once every two days for 21 days, the establishment of mouse erythrocytes increased mainly polycythemia vera, continuing every two days after injec...
