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.
Huangfu Mi said: Some individuals experience sore throat, nasal congestion, and discharge of clear rhinorrhea. This results from wearing warm clothing near fire sources. One should promptly remove clothes, wash with cold water, and apply cold stones to the pharynx and cheeks while facing the wind for five or six times; the condition will heal spontaneously.

Scutellariae Radix (Huangqin, 3 liang); Gardeniae Fructus (Zhizi, 4 pieces); Fermented Soybean (Chishao/Douchi, 3 sheng).
Crush these three ingredients. Add 5 sheng of water. First decoct Zhizi and Huangqin until reduced to 3 sheng. Strain to remove dregs. Then add Douchi and decoct until the liquid becomes concentrated. Strain again. Take 1 sheng at dawn, three times daily. The effect is excellent.
