Hyperpyrexia refers to fever that persists continuously without abating. This condition arises from the stagnation and excess of blood and qi, generating internal heat within the five zang organs. When this heat steams and scorches internally, it leads to restlessness in sleep and posture, as well as mental confusion; when it薰 (pervades) outwardly, it results in heat affecting both the interior and exterior, accompanied by irritability, panting, and coarse breathing. In severe cases, it may even trigger convulsions and epilepsy. For mild cases, Huofu Dan (Fire Mansion Pill) or Dihuang Jian (Rehmannia Decoction) may be used.
