If the patient is in a state of delirium, high fever and convulsions, or fainting and delirium during the cerebral hemorrhage, Angong Niuhuang Wan can be used to calm the mind, open the orifices, clear the heat and detoxify the toxins, and lower the patient’s body temperature. Angong Niu Huang Wan is mainly for the treatment of feverish symptoms after cerebral hemorrhage, and does not treat cerebral hemorrhage disease per se. Cerebral hemorrhage is caused by the sudden rupture of cerebral blood vessels due to various reasons, and the blood in the blood vessels overflows into the brain cells and brain parenchyma of the patient, leading to damage to the brain cells of the patient and causing acute neurological deficits. Cerebral hemorrhage has a very high rate of disability and death, and the treatment is mainly based on the amount of bleeding to choose a plan. If the bleeding volume is large, it needs to be treated by surgery, and if the bleeding volume is small, it can be treated conservatively by internal medicine, dehydration, lowering the cranial pressure, reducing the cerebral edema, and at the same time, preventing the bleeding from continuing, and giving medicines to promote the restoration of neurological function.
