病腹满，发热，十日脉浮而数，饮食如故，厚朴七物汤主之。
【注】
病腹满，里证也。发热，里热也。然十日脉浮而数，表热亦未已也，饮食如故，胃热
能消谷也。因胃热里实，表热发热，故用厚朴七物汤，表里均解，腹满发热两除也。
此桂枝汤、小承气汤之复方也。
【集注】
程林曰：腹满者，内有实热也。十日脉尚浮而数，浮为在表，表热邪未已，故发热，
数为在里，里热能消谷，故饮食如故，与此方荡腹满而除表热。夫表里俱实，当先解
表，乃可攻里，今表邪微而里邪甚，故用承气桂枝二汤，相合以和表里，如伤寒之用
大柴胡，此其义也。

When the disease presents with abdominal fullness, fever, a duration of ten days, a floating and rapid pulse, and normal appetite, Houpo Qiwu Tang (Magnolia Bark Seven-Ingredient Decoction) is indicated.
[Annotation]
Abdominal fullness indicates a interior syndrome. Fever indicates interior heat. However, since the pulse remains floating and rapid after ten days, exterior heat has not yet resolved. Normal appetite indicates that stomach heat can digest food. Due to stomach heat and interior excess combined with exterior heat and fever, Houpo Qiwu Tang is used to resolve both exterior and interior simultaneously, eliminating both abdominal fullness and fever.
This is a compound formula of Guizhi Tang (Cinnamon Twig Decoction) and Xiao Chengqi Tang (Minor Order the Yang Decoction).
[Collected Annotations]
Cheng Lin stated: Abdominal fullness is due to interior excess heat. The pulse remaining floating and rapid after ten days indicates that floating signifies the exterior, where exterior pathogenic heat persists, causing fever; rapid signifies the interior, where interior heat digests food, hence normal appetite. This formula is given to purge abdominal fullness and clear exterior heat. When both exterior and interior are excess, one should typically resolve the exterior first before attacking the interior. Here, the exterior pathogen is mild while the interior pathogen is severe, so Chengqi Tang and Guizhi Tang are combined to harmonize the exterior and interior, similar to the use of Da Chaihu Tang (Greater Bupleurum Decoction) in Shanghan (Cold Damage), sharing the same principle.
Houpo (Magnoliae Officinalis Cortex) half jin, Gancao (Glycyrrhizae Radix et Rhizoma) 3 liang, Da Huang (Rhei Radix et Rhizoma) 2 liang, Dazao (Ziziphi Jujubae Fructus) 10 pieces, Zhishi (Aurantii Fructus Immaturus) 5 pieces, Guizhi (Cinnamomi Ramulus) 2 liang, Shengjiang (Zingiberis Rhizoma Recens) 5 liang.
The above seven herbs are boiled in 1 dou of water until reduced to 4 sheng. Take 8 he of the decoction warm, three times daily. If vomiting occurs, add Banxia (Pinelliae Rhizoma) 5 he. If diarrhea occurs, remove Da Huang. If there is excessive cold, increase Shengjiang to half jin.

If pressing the epigastrium reveals fullness and pain, this is an excess syndrome, requiring purgation, and Da Chaihu Tang (Greater Bupleurum Decoction) is appropriate.
[Commentary]
Below "pressing the epigastrium reveals fullness and pain," the phrase "with tidal fever" (you chao re) should be present. Without these three characters, Da Chaihu Tang would not be indicated; this is likely an omission during transcription.
[Annotation]
Pressing the epigastrium revealing fullness and pain, accompanied by tidal fever, indicates both exterior and interior excess. Purgation is required, and Da Chaihu Tang is suitable to resolve both exterior and interior. Both of these treatments are methods for purging interior excess and fullness.
