桃仁（五十个，去皮尖，味甘，性平） 桂枝（二两，去皮，味辛，性热） 大黄（四两） 芒硝（四两） 甘草（二两，炙用）
以上五味药。用水七升。煮取药液二升半。滤去药渣。加入芒硝。再次上火微沸后离火。饭前服用。每次温服五合。每日三次服药。应当出现轻微腹泻。
甘味药可以缓急止痛。辛味药可以发散邪气。少腹拘急结聚。用桃仁的甘味来缓解。下焦蓄血。用桂枝辛热的性质来消散。寒凉药可以攻逐实邪。热盛搏结血液。所以在调胃承气汤中加入这两味药。
王宇泰说：按照上述详细研读。应当是桂（肉桂）。而不是桂枝。因为桂枝轻扬上行治上焦。桂（肉桂）浓重下行治下焦。成无己随文顺释。不足以作为依据。
伤寒病八九天。误用下法。出现胸满、烦躁惊悸。小便不利。胡言乱语。全身沉重。不能翻身转侧的。用柴胡加龙骨牡蛎汤主治。
伤寒病八九天。正是热气游行之时。误用下法导致里虚。则热气散漫错杂而进入胸中。则胸部胀满而烦躁惊悸。进入膀胱则小便不利。进入胃中则胡言乱语。进入脾脏则全身沉重。
伤寒病八九天。邪气已经化热。又正在传变至阳经的时候。误用下法。导致里虚而热邪不除。胸部胀满而烦躁。这是阳热客居于胸中。惊悸。是因为心恶热而神志不守。小便不利。是因为里虚津液运行不畅。胡言乱语。是因为胃热。全身沉重。不能翻身转侧。是因为阳气内行于里。不能营运于体表。给予柴胡汤。以消除胸满和烦躁。加入龙骨、牡蛎、铅丹。收敛神气而镇惊。加入茯苓以运行津液。通利小便。加入大黄以驱逐胃热。停止胡言乱语。加入桂枝以运行阳气。而解除身重及错杂之邪。这样全部痊愈了。
Peach Kernel (Shao Ren, 50 seeds, skin and tip removed; sweet flavor, neutral nature) Cinnamon Twig (Guizhi, 2 liang, bark removed; pungent flavor, hot nature) Rhubarb (Dahuang, 4 liang) Mirabilite (Mangxiao, 4 liang) Licorice Root (Gancao, 2 liang, honey-fried)
The above five herbs. Boil with seven sheng of water. Decoct to obtain two and a half sheng of liquid. Strain out the dregs. Add Mirabilite. Reheat over fire until slightly boiling, then remove from heat. Take before meals. Warm dose: five ge. Three doses per day. A slight purgation is expected.
Sweet flavors can relieve urgency. Pungent flavors can disperse pathogens. Lower abdominal stiffness and binding are relieved by the sweetness of Peach Kernel. Blood stasis in the lower jiao is dispersed by the pungent and hot nature of Cinnamon Twig. Cold-natured drugs are used to overcome excess. Heat exuberance clots blood; therefore, these two herbs are added to Tiaowei Chengqi Tang (Regulate the Stomach Purging Decoction).
Wang Yutai stated: Upon detailed examination of the above, it should be Cinnamon Bark (Rougui), not Cinnamon Twig (Guizhi). For Cinnamon Twig is light and ascending, treating the upper jiao; Cinnamon Bark is heavy and descending, treating the lower jiao. Cheng Wuji's interpretation following the text is insufficient as evidence.
In Taiyang disease for eight or nine days, after erroneous purgation, if there is chest fullness, irritability, palpitations, difficulty in urination, delirium, heaviness of the whole body, and inability to turn over, Chaihu Jia Longgu Muli Tang (Bupleurum plus Dragon Bone and Oyster Shell Decoction) is indicated.
In Taiyang disease for eight or nine days, which is the time when pathogenic heat wanders, erroneous purgation empties the interior. Consequently, pathogenic heat scatters and mixes, entering the chest, causing fullness, irritability, and palpitations. Entering the Bladder causes difficulty in urination. Entering the Stomach causes delirium. Entering the Spleen causes heaviness of the whole body.
In Taiyang disease for eight or nine days, when pathogenic qi has transformed into heat and is transmitting to the Yang meridians, erroneous purgation empties the interior while heat remains. Chest fullness and irritability indicate Yang-heat lodging in the chest. Palpitations occur because the Heart dislikes heat and the Spirit fails to remain anchored. Difficulty in urination results from interior deficiency and impaired fluid circulation. Delirium is due to Stomach-heat. Heaviness of the whole body and inability to turn over result from Yang-qi moving inward to the interior and failing to nourish the exterior. Administer Chaihu Tang (Bupleurum Decoction) to eliminate chest fullness and irritability. Add Longgu (Dragon Bone), Muli (Oyster Shell), and Qiandan (Lead Monoxide) to consolidate the Spirit and calm palpitations. Add Fuling (Poria) to promote fluid circulation and facilitate urination. Add Dahuang (Rhubarb) to purge Stomach-heat and stop delirium. Add Guizhi (Cinnamon Twig) to circulate Yang-qi and resolve the heaviness and mixed pathogens. Thus, all symptoms will be cured.
