The *Neijing* (Inner Canon) states that Shaoyin Kidney Malaria, when affecting the meridians, causes vomiting. The chills and fever are severe, with more heat than cold. The patient desires to stay in a room with doors and windows closed. This condition is difficult to cure.
This occurs because the Qi storage mechanism of the Kidney is obstructed, leading to this syndrome.
