(1) Taiyang Syndrome: Headache, fever with chills, floating pulse. ① If there is no sweat and the pulse is tight, it is cold damage (narrow sense); use Mahuang Decoction. ② If there is sweat and the pulse is slow, it is wind-cold; use Guizhi Decoction. ③ If there is thirst and the pulse is rapid, it is a warm disease (Zhongjing did not formulate a prescription).

(2) Yangming Syndrome: High fever, intense thirst, profuse sweating, and a full, bounding pulse indicate Yangming meridian syndrome; distention, fullness, dryness, and constipation indicate Yangming腑syndrome. Use Baihu Decoction for meridian syndrome; use Chengqi Decoction for腑syndrome.

(3) Shaoyang Syndrome: Bitter taste in the mouth, dry throat, dizziness, alternating chills and fever, chest and flank discomfort, irritability and nausea, reluctance to eat or drink—use Xiaochaihu Decoction; if accompanied by headache, chills, and fever, it is a combined Shaoyang–Taiyin syndrome, use Chaihu Guizhi Decoction; if accompanied by constipation and yellow tongue coating, it is a combined Shaoyang–Yangming syndrome, use Dachaihu Decoction.
