When the seasonal qi disease (exogenous febrile disease) persists for eight or nine days without resolution, it may be due to the meridians being re-exposed to pathogenic factors, or because the toxic pathogens have not been fully cleared after previous treatments such as sweating, vomiting, or purging. Consequently, the illness cannot be eradicated. Alternatively, if a single meridian is affected and the disease has not yet transmitted to other meridians, the pathogen may stagnate for several days with unchanged symptoms. In all these cases, treatment should be guided by careful observation of the syndrome patterns.
For seasonal qi disease persisting for eight or nine days, characterized by hardness and fullness in the heart and abdomen, body pain, internal and external heat, irritability, vomiting, and restlessness, the Qianhu San Formula is indicated.
Qianhu (Radix Peucedani), 1 liang, with the rhizome removed; Banxia (Rhizoma Pinelliae), 1 liang, washed seven times with hot water to remove slipperiness; Zhike (Fructus Aurantii Immaturus), 3 fen, stir-fried with bran until slightly yellow, with the pith removed; Chishao Yao (Radix Paeoniae Rubra), 2 or 3 fen; Huangqin (Radix Scutellariae), 3 fen; Maimendong (Radix Ophiopogonis), 1 liang, with the core removed.
Crush and sieve the above ingredients into a powder. Take 5 qian per dose. Add 1 large cup of water, 0.5 fen of Shengjiang (Rhizoma Zingiberis Recens), and 1 fen of Zhuru (Caulis Bambusae in Taeniam). Decoct until only 0.5 cup remains. Strain the dregs. Take warm, regardless of meal times.

Jiegeng (Radix Platycodonis), 1 liang, with the rhizome removed; Gancao (Radix Glycyrrhizae), 3 fen, stir-baked until slightly red and then cut into small pieces; Mahuang (Herba Ephedrae), 1 liang, with roots and nodes removed; Xingren (Semen Armeniacae Amarum), 1 liang, soaked in water, skin and pointed ends removed; if double-kernel, stir-fry with bran until slightly yellow; Huangqin (Radix Scutellariae), 3 fen; Maimendong (Radix Ophiopogonis), 1 liang, with the core removed.

For seasonal qi disease persisting for eight or nine days, presenting with pain in the joints, unrelenting heat toxicity, alternating chills and fever, fluctuating severity and remission, and attacks resembling malaria, the Biejia San Formula is indicated.
Biejia (Carapax et Plastrum Testudinis), 2 liang, coated with vinegar and stir-baked until slightly yellow, with the skirt removed; Zhimu (Rhizoma Anemarrhenae); Huangqin (Radix Scutellariae); Wumei Rou (Sarcocarpus Mume), lightly stir-fried; Chaihu (Radix Bupleuri), with the crown removed; Hengshan (Radix Dichroae); Digupi (Cortex Lycii); Chishao Yao (Radix Paeoniae Rubra); Niuxi (Radix Achyranthis Bidentatae), with the crown removed (all above at 1 liang each); Gancao (Radix Glycyrrhizae), 0.5 liang, stir-baked until slightly red and cut into small pieces.

After ingestion, continue to drink freshly drawn cool water as desired. The appearance of sweat indicates efficacy.
