Cerebral infarction can take Angong Niuhuang Pills mainly for patients with severe disease. In case of large cerebral infarction and brainstem infarction, patients can often have impaired consciousness, such as drowsiness, lethargy or coma. Patients with impaired consciousness can use Angong Niuhuang Pill, which is mainly applicable in the recovery and acute phases. If the patient enters the posterior phase, application is generally not advocated. Patients in the sequelae phase refer to one year after the onset of the disease, and their treatment effect is generally poor, mainly giving rehabilitation treatment and limb function exercise to prevent muscle atrophy or contracture. For patients with large cerebral infarction, there can be cerebral edema and increased intracranial pressure at the same time. If patients have cerebral edema, they should be given timely cranial pressure lowering treatment, mainly applying mannitol, glycerol fructose and tachyphylaxis. For patients with impaired consciousness, they should also be given wakefulness treatment with brain-alerting, Qingkai Ling or compound musk.
