The invention relates to the technical field of traditional Chinese medicine compositions, in particular to a traditional Chinese medicine composition and a preparation method and application thereof. Specifically, the traditional Chinese medicine composition is prepared from radix salviae miltiorrhizae, rhizoma coptidis, rhizoma anemarrhenae, radix ophiopogonis, nacre mother of pearl and semen ziziphi spinosae. The traditional Chinese medicine composition provided by the invention is simple in formula, does not contain precious, thin, toxic and endangered medicinal materials, and in a naturally aged female climacteric mouse model, the traditional Chinese medicine composition formula can obviously increase the level of E2 in plasma, lower the levels of FSH and LH and improve the pathological characteristics of uterus tissues. Test results show that the traditional Chinese medicine composition provided by the invention has a certain treatment effect on patients with perimenopausal syndromes.

The invention discloses a traditional Chinese medicine composition for treating tachyarrhythmia and a preparation method and application thereof, and belongs to the field of traditional Chinese medicines. The traditional Chinese medicine composition comprises the following raw material medicines in parts by weight: 12-20 parts of codonopsis pilosula, 15-30 parts of astragalus membranaceus, 10-15 parts of angelica sinensis, 8-12 parts of ligusticum wallichii, 15-20 parts of tuber fleeceflower stem, 12-15 parts of poria with hostwood, 10-15 parts of ochre, 10-15 parts of nacre mother of pearl, 6-10 parts of ginger processed pinellia, 10-15 parts of poria cocos, 6-10 parts of rhizoma nardostachyos, 3-6 parts of subprostrate sophora, 1-3 parts of leech and 3-6 parts of raw liquorice.
