Huangfu Mi said: Some individuals suffer from swollen and ulcerated lips, loose and painful teeth, and stiffness of the cheeks with trismus (jaw lock). This is caused by exposure to heat pathogens without timely intervention. One should open the mouth facing the wind to allow cool air to enter the pharynx, and gargle with cold water; the condition will then resolve.
