Brief Summary

The most common cause of death for Chinese patients is intracerebral hemorrhage(ICH), particularly cerebral infarction. It places a heavy burden on people, families, and society as a whole and poses considerable risks of death and disability. The disease is difficult to identify, and is frequently detected only after it progresses to the point of vascular cognitive dysfunction. The primary ischemia necrosis of brain nerve cells and the activation of inflammatory cells are their pathologic processes. According to historical Chinese medical documents, bezoar possesses properties that can help prevent seizures, treat strokes, enhance cognitive function and mental well-being, and stimulate alertness. Calculus Bovis Sativus (CBS) is the most authentic formulation of bezoar ingredients compared to other bezoar products. It has received approval from the China Food and Drug Administration for the essential treatment of comatose patients. CBS consists of three primary constituents: bilirubin, bile acids, and taurine. Scientific evidence has demonstrated that all of these components possess anti-inflammatory, antioxidant, and neuroprotective properties. The investigators' objective is to carry out an investigator-initiated clinical study to assess the efficacy of orally administered CBS in treating intracerebral hemorrhag diseases in humans.
