大黄四两，芒硝三合，牡丹皮，桃仁五十个，瓜子半升（应当是甜瓜子）。
以上五味药，用水六升，煮取一升药液，滤去药渣，加入芒硝，再次煮沸，一次性服用。如果有脓，应当排出脓液；如果没有脓，应当排出瘀血。
《金匮要略》上一章使用了附子，后人强行将小肠痈解释为寒邪凝结，此方使用大黄、芒硝，又妄自将大肠痈解释为热邪凝结，这不符合肺气的生理特性。硝石能够开通闭塞，下行通腑，这是必然的道理。
枳实十六枚，芍药六分，桔梗二分。
以上三味药，捣碎成散剂，取鸡蛋黄一枚，用药散与鸡蛋黄等量，揉和均匀使其融合，用温水送服，每日一次。
甘草二两，桔梗三两，生姜一两，大枣十枚。
以上四味药，用水三升，煮取一升药液，温服五合，每日两次。

白芷一钱，防风七分，陈皮一钱五分，皂角刺五分，穿山甲三片（切片，用蛤粉炒），土贝母一钱，金银花三钱。

外科的方剂最为繁杂，起初没有深奥的意义，难以分类选取，这里选取通用的方剂来阐释它。如活命饮，具有通行卫气、消除肿胀，调和营血、止痛的功效，是治疗疮疡肿毒初起的首选方剂。
Rhizoma Rhei (Dahuang) 4 liang, Natrii Sulfas (Mangxiao) 3 he, Cortex Moutan (Danpi), Semen Persicae (Taoren) 50 seeds, Semen Cucurbitae (Gua Zi) half sheng (likely Semen Citrulli/Dian Gua Zi).
Take the above five herbs, add six sheng of water, decoct to obtain one sheng of liquid, remove the dregs, add Natrii Sulfas (Mangxiao), boil again until boiling, and take in one dose. If pus is present, it should be discharged; if no pus, blood stasis should be discharged.
In the previous chapter of *Jin Gui Yao Lue* (Essential Prescriptions from the Golden Cabinet), Fuzi (Radix Aconiti Lateralis Preparata) was used. Later scholars forcibly attributed Intestinal Abscess of the Small Intestine (Xiaochang Yong) to cold accumulation. This prescription uses Rhizoma Rhei (Dahuang) and Natrii Sulfas (Mangxiao), and wrongly attributes Intestinal Abscess of the Large Intestine (Dachang Yong) to heat accumulation. This contradicts the physiological nature of Lung Qi (Fei Qi). Natrii Sulfas (Mangxiao) opens blockages and promotes downward purgation; this is the principle.
Fructus Aurantii Immaturus (Zhishi) 16 pieces, Radix Paeoniae Rubra (Shaoyao) 6 fen, Radix Platycodi (Jiegeng) 2 fen.
Pulverize the above three herbs into a powder. Take one egg yolk. Mix an equal amount of the herb powder with the egg yolk, knead until well combined, and take with warm water. Administer once daily.
Radix Glycyrrhizae (Gancao) 2 liang, Radix Platycodi (Jiegeng) 3 liang, Rhizoma Zingiberis Recens (Shengjiang) 1 liang, Fructus Jujubae (Dazao) 10 pieces.
Take the above four herbs, add three sheng of water, decoct to obtain one sheng of liquid. Take five he as a warm dose, twice daily.
"Pai" (Discharge) means to expel. "Nong" (Pus) is transformed from flesh and blood. In the preceding formula, Zhishi (Fructus Aurantii Immaturus) and Shaoyao (Radix Paeoniae Rubra) are assisted by Jiegeng (Radix Platycodi) to directly vent qi and break blood stasis through the Large Intestine, expelling pus. The latter... self...
Seven fresh Calabash Gourd Pedicels (Qie Di), Fresh Polygonum Multiflorum Radix (Heshouwu) (equal parts according to severity).
Add two zhong of water, decoct to eight fen. One dose discharges pus; a second dose promotes wound healing.
Duikou Boil (Opposite-Neck Furuncle) occurs at the empty space of the Yamen acupoint, caused either by upward congestion of damp-toxin or by hyperactive fire due to Kidney deficiency. Patients often suffer from ulceration that fails to heal, or rot spreading around the neck, even... He...
Radix Angelicae Dahuricae (Baizhi) 1 qian, Radix Saposhnikoviae (Fangfeng) 7 fen, Pericarpium Citri Reticulatae (Chenpi) 1.5 qian, Spina Gleditsiae Sinensis (Zaojiaoci) 5 fen, Squama Manis (Chuanshanjia) 3 slices (sliced, stir-fried with Concha Meretrix/Clausi), Radix Bletillae (Tubeimu) 1 qian, Flos Lonicerae Japonicae (Yinhua) 3 qian.
Decoct with half wine and half water for dozens of boils, and take immediately.
Surgical prescriptions are numerous and complex, originally lacking profound meaning, making them difficult to categorize. Here, common prescriptions are selected for explanation. For example, Huoming Yin (Immortal Life Decoction) circulates Wei Qi (Defensive Qi) to reduce swelling, harmonizes Ying Blood (Nutritive Blood) to relieve pain. It is the primary prescription for...
