Embodiment 1
[0022] The crude drug formula of the traditional Chinese medicine composition of this example is as follows: Codonopsis pilosula 25g, Sophora japonicus 10g, Cork 8g, Astragalus complanatus 6g, Pearl powder 3g, Amber powder 3g and Chuan Fritillaria 6g.
[0023] The raw materials of the above formula are mixed, crushed and passed through an 80-100 mesh sieve to obtain raw raw materials powder, and the above-mentioned powder is filled into a commercially available capsule shell to form a capsule, wherein each capsule contains 0.5g of the fine powder.
Embodiment 2
[0025] The crude drug formula of the traditional Chinese medicine composition of this embodiment is as follows: Codonopsis pilosula 20g, Sophora japonicus 10g, Cork 10g, Astragalus complanatus 10g and pearl powder 1.5g.
[0026] After mixing the above-mentioned raw materials, pulverizing them, decocting them with water 20 times the weight of the medicinal materials, decocting and extracting 2 times, each extraction for 2 hours, and then collecting and combining the extracts, and the extracts are concentrated The extract with a density of 1.15 is diluted with 7 times the volume of the extract and filtered to obtain a clarified extract; the clarified extract is passed into the macropores with a flow rate of 10 times the bed volume / hour for adsorption, washing, and analysis. The adsorption resin column is first washed with water, then washed with 20% ethanol, and finally analyzed with 50% ethanol; the analyzed solution is recovered to alcohol-free, concentrated, spray-dried to obtain...
Embodiment 3
[0028] The crude drug formula of the traditional Chinese medicine composition of this embodiment is as follows: Codonopsis pilosula 25g, Sophora japonicus 10g, Cork 10g, Astragalus complanatus 10g, Pearl powder 1.5g, Amber powder 1.5g and Chuan Fritillaria 6g.
[0029] The raw materials of the above formula are mixed, after preliminary pulverization, the ultrafine powder is made into 1-10μm ultrafine powder by ultrafine pulverization technology, and the above ultrafine powder is mixed with physiological saline to form a suspension to prepare a liquid, wherein each 5ml of physiological saline Mixed with 1.0g of superfine powder.
