Li, male, 25 years old. Suffered from a common cold for one week. After taking oral medications such as "Common Cold Relief," the symptoms of external contraction mostly subsided, but then night sweats appeared for three days. Upon examination, the tongue coating was thin and white, and the pulse was wiry. This condition was attributed to lingering pathogens from the external contraction. The treatment involved Minor Bupleurum Decoction, and after three doses, the patient recovered.
