The invention relates to a method for producing Dafeng pills for treating
low back pain by utilizing the micro-
powder technology, which can effectively solve the poor
treatment effect of the Dafeng pills and comprises the following steps: taking
jelly fungus, Chinese angelica, white paeony root, twotooth
achyranthes root, common floweringquince fruit, platycodon root,
eucommia bark, swordlike atractylodes
rhizome and doubleteeth pubescent angilica root with the total amount of 100% as pharmaceutical raw materials for production, respectively spraying and cleaning the drugs with water, placing into an oven,
drying, mixing, smashing, screening, sterilizing, cooling, further screening, obtaining micro-
powder of the mixture, adding rice vinegar into the micro-
powder, evenly mixing, making pills, and
drying. The release amount and the release rate of active ingredients of the Dafeng pills prepared by utilizing the micro-powder technology, as well as the
human body absorption amount of the active ingredients of the drugs in unit time are higher than those of the Dafeng pills prepared by the smashing method of screening with the
pore diameter of 150 mu m, and the method can further significantly improve the
bioavailability, significantly shorten the onset time of the drugs, greatly reduce the dosage, significantly improve the
efficacy and essentially improve the quality and the efficiency in comparison with the existing Dafeng pills.
