The invention discloses a
traditional Chinese medicine for treating Alzheimer
disease as well as a preparation method and application thereof. The
traditional Chinese medicine comprises the following components in parts by
mass: 15 parts of
codonopsis pilosula, 15 parts of
astragalus mongholicus, 12 parts of rhizoma polygonati, 6 parts of
polygonum multiflorum, 10 parts of
curcuma aromatica, 8 parts of rhizoma acori graminei, 10 parts of
ligusticum wallichii and 8 parts of
earthworm. The method comprises the following steps of: adding the
curcuma aromatica, the rhizoma acori graminei and the
ligusticum wallichii into deionized water, heating for distilling and extracting volatile oil, dehydrating the volatile oil, clathrating with beta-
cyclodextrin and
drying at low temperature; collecting a
distilled water solution with another vessel, adding the
codonopsis pilosula, the
astragalus mongholicus, the rhizoma polygonati, the
polygonum multiflorum and
earthworm into water, decorating, mixing decoctions, filtering to obtain filtrate, mixing the filtrate with the
distilled water solution, concentrating to obtain concentrate, adding 95%
ethanol to the concentrate to ensure that the
alcohol precipitation concentration is 60%, fully stirring, standing for 24-48 hours, filtering to obtain filtrate, recovering
ethanol from the filtrate, concentrate the filtrate subjected to
ethanol removal to form thick paste and performing
microwave drying on the thick paste to form a dry extract; and crushing the dry extract, adding a defined amount of
dextrin or
starch, performing wet
granulation,
drying and
granulation, adding a volatile oil
clathrate compound and uniformly mixing. By adopting methods of invigorating
spleen and
kidney, eliminating
phlegm and dispersing
blood stasis, the brain premature senility and
brain aging are prevented and intervened, thereby delaying the development of the Alzheimer
disease, improving the clinical symptoms and improving the
life quality of patients.
