The invention provides a traditional Chinese medicine preparation for cerebral arterial thrombosis and a preparation method thereof, and relates to the technical field of traditional Chinese medicine pharmacy, the traditional Chinese medicine preparation is prepared from trichosanthes kirilowii maxim, inula flower, tamarix chinensis, arisaema cum bile, calculus bovis factitius, hawksbill, erigeron breviscapus, rhodiola rosea, radix paeoniae rubra, radix curcumae, herba lycopi, campsis grandiflora, catechu and benzoin. Comprehensive animal experiment and clinical research results show that the traditional Chinese medicine preparation has a remarkable treatment effect on cerebral arterial thrombosis, mNSS scores of MCAO rats can be remarkably reduced, the cerebral infarction volume can be reduced, meanwhile, inflammatory response balance in vivo can be adjusted, and inflammation-mediated brain injury can be relieved; the preparation can also significantly reduce the NIHSS score and the traditional Chinese medicine syndrome score of the cerebral arterial thrombosis patient, increase the BI score, effectively regulate the serum inflammatory factor balance, and significantly improve the total effective rate of clinical treatment. In conclusion, the preparation plays the roles of nerve protection, anti-inflammation and function recovery promotion through multiple targets, and a safe and effective new scheme is provided for treatment of cerebral arterial thrombosis.

This invention provides a method for extracting active ingredients from *Erigeron breviscapus*, belonging to the field of pharmaceutical technology. Based on the differences in the physicochemical properties of the compounds, this invention first achieves preliminary separation of caffeic acid esters and scutellarin, followed by further purification and separation based on the properties of the two types of substances. Specifically, this invention uses ethanol-water solutions of different concentrations to extract caffeic acid esters stepwise, and uses macroporous and microporous resins for preliminary separation of the caffeic acid esters. Scutellarin is then preliminarily separated through acid-base treatment. Finally, high-purity scutellarin, 3,5-dicaffeoylquinic acid, 3,4-dicaffeoylquinic acid, 4,5-dicaffeoylquinic acid, and scutellarin are obtained through reversed-phase industrial chromatography. This invention achieves the extraction and separation of multiple active ingredients from *Erigeron breviscapus*, and all solvents used in the extraction and separation process are recyclable, resulting in low cost.

This invention belongs to the field of drug detection technology, specifically relating to a detection method for *Erigeron breviscapus* (Dendrobium nobile) formula granules. These granules are made from *Erigeron breviscapus* medicinal slices through decoction, concentration, drying, and granulation. The detection method includes morphology, identification, inspection, extractives, characteristic chromatograms, and content determination. The identification method uses thin-layer chromatography; the characteristic chromatogram uses high-performance liquid chromatography, with the baicalin reference peak as the S peak, indicating 11 characteristic peaks; and the content determination measures the content of baicalin. The detection method established by this invention improves the detection requirements for *Erigeron breviscapus* medicinal materials, medicinal slices, standard decoctions, and formula granules, contributing to the establishment of a comprehensive quality control system for various *Erigeron breviscapus* products and helping to ensure the quality and clinical efficacy of *Erigeron breviscapus* formula granules.

The invention discloses a traditional Chinese medicine formula for preventing and treating cerebrovascular diseases. The traditional Chinese medicine formula comprises Yulangsan, bauhinia championii, corydalis amabilis, lumbricus, astragalus membranaceus, ligusticum chuanxiong hort, cassia twig, radix paeoniae rubra, safflower, rhizoma acori graminei and erigeron breviscapus. The traditional Chinese medicine composition has good clinical effects on treating cerebral atherosclerosis, stenosis, infarction, atherosclerosis and apoplexy sequelae, hemiplegia, aphasia and the like caused by cerebral atherosclerosis, stenosis, infarction and atherosclerosis, and can gradually or basically recover the apoplexy sequelae caused by cerebral atherosclerosis, stenosis, infarction and atherosclerosis; yulangsan and bauhinia championii have the effects of relaxing tendons and activating collaterals, and corydalis amabilis, ligusticum wallichii, radix paeoniae rubra and safflower have the effects of promoting blood circulation and removing blood stasis and are The earthworm, the cassia twig, the rhizoma acori graminei and the erigeron breviscapus are used for dredging brain collaterals and are assistant and guide; the whole formula has the effects of tonifying qi, activating blood, dispersing blood stasis, dredging collaterals, inducing resuscitation and inducing resuscitation.

This invention provides a composition with menstrual regulating and blood-activating effects and its application in the preparation of external products, relating to the field of biomedical technology. This invention utilizes a composition composed of Chinese herbal raw materials including *Cephalotaxus fortunei* bark, star anise, *Erigeron breviscapus*, *Piper longum*, *Caulis thunbergii*, *Radix Achyranthis Bidentatae*, *Radix Scutellariae*, *Radix Achyranthis Bidentatae*, *Radix Panax notoginseng*, *Radix Bambusae in Taeniam*, and *Radix Achyranthis Bidentatae* to prepare a traditional Chinese medicine acupoint patch for treating or improving primary dysmenorrhea. The herbal acupoint patch can inhibit the expression of inflammatory factors, downregulate the expression level of COX-2, thereby inhibiting PGF2α, increasing the level of PGE2, and reducing uterine tissue inflammation, achieving multi-target treatment of primary dysmenorrhea. The herbal acupoint patch utilizes the power of the medicine through the acupoint, and the acupoint utilizes the properties of the medicine. The meridians are the channels, and the acupoints are the gateways. The medicinal power directly reaches the Chong and Ren meridians and the uterus, so that cold is warmed and dispelled, blood stasis is cleared and eliminated, and qi and blood flow smoothly, thus curing dysmenorrhea. It plays a role in warming the meridians and dispelling cold, promoting qi and blood circulation, removing blood stasis and relieving pain, providing a new direction for the external treatment strategy of traditional Chinese medicine for primary dysmenorrhea.
