至元壬午，有人王伯禄，年五十有七，上臂膊肿盛，上至肩，下至手指，色变，皮肤凉，
六脉沉细而微，脉证俱寒。举疡（疡医）彦和视之，曰此乃附骨痈，开发已运，以燔起之脓

至元壬午年，有一位名叫王伯禄的人，五十七岁，上臂肿胀严重，肿势向上延伸至肩部，向下延伸至手指，肤色改变，皮肤发凉，六脉沉细而微弱，脉象与症状均表现为寒证。疡医彦和诊治后说，这是附骨痈，脓液已经成熟流动，但质地清稀且散漫，建议等待时日肘部下方再次切开排脓。随后患者出现呃逆不止的症状，彦和给予丁香柿蒂汤服用两剂，稍见缓解。又过几日，咳逆更加严重，并伴有自发性腹泻，脐腹部冷痛，腹胀，饮食减少，不久出现昏沉迷糊的症状。彦和在左侧乳头下黑色尽处施灸十四壮，又处方包含干姜、附子、木香、沉香、茴香、羌活等药物，切碎一两半，准备给患者服用。有人说道：“各种疼痛、瘙痒、疮疡，都属于心火。”况且正值盛夏酷暑，使用干姜、附子等大热之药可以吗？我回答说：理所当然。《内经》中说：脉象细弱、皮肤寒冷、前后二便泄泻、饮食无法入口，这称为“五虚”。呃逆，是胃气极度虚弱的表现。虽然各种肿疡疮疡大多属于心火，这是常理定理。但此证候内外表现相反，必须舍弃时令常规而顺从病证，如果不使用大剂量辛热药剂紧急治疗，就不能痊愈。于是投以此药，所有症状全部消除，饮食恢复，疮势转温，脓色正常。彦和又给予五香汤服用数剂，一个多月后康复。唉！墨守成规，是普通人的见识；懂得变通，才是处理大事的关键。只知道常规而不知道变通，因此导致失败的人很多，何况是医学呢？坚守常规与懂得变通，难道可以相提并论吗！
To treat swelling and pain in the cheek and jaw, or ulceration into sores.
Take *Hibisci Mutabilis Folium* (Furong Ye) [Cotton Rose Leaf] (quantity not restricted).
Mash it into a paste and apply externally to the affected area, secure with cloth, and change once daily.
Take *Realgar* (Xionghuang) above, grind into powder, mix with vinegar for topical application, and simultaneously take mixed with wine orally. This is applicable for snake bites as well as injuries from bees, scorpions, centipedes, venomous insects, and mad dogs.
To treat sores arising around the anus that persist and do not heal for a long time.
Take *Gallus gallus domesticus Brisson* (Ji Nei Jin) [Chicken Gizzard Lining], specifically the inner yellow membrane removed from the gizzard, quantity not restricted. Burn it to ash while retaining its properties, grind into an extremely fine powder, and apply dry directly to the lesion each time; the effect is miraculous.
In the Renwu year of the Zhiyuan era, a person named Wang Bolu, aged fifty-seven, suffered from severe swelling of the upper arm, extending upwards to the shoulder and downwards to the fingers. The skin color changed, and the skin was cold. The six pulses were deep, fine, and faint; both pulse and symptoms indicated a cold syndrome. Yan He, a surgeon, examined him and said, "This is a deep-rooted abscess (Fugu Yong). The pus has matured and is flowing, but it is clear, thin, and diffuse. Wait for a few days until the area below the elbow is opened again." Subsequently, the patient developed incessant hiccups. Yan He administered Dingxiang Shidi Tang (Clove and Persimmon Calyx Decoction) for two doses, providing slight relief. A few days later, the hiccups became even more severe, accompanied by spontaneous diarrhea, cold pain in the umbilical and abdominal regions, abdominal fullness, reduced food intake, and episodes of sudden dizziness and confusion. Yan He applied moxibustion for fourteen moxa cones at the point where blackness ended under the left breast. He then prescribed a formula containing *Zingiberis Rhizoma Recens* (Ganjiang), *Aconiti Lateralis Radix Praeparata* (Fuzi), *Lithospermum Erythrorhizon* (Muxiang - *Note: Context implies Aucklandia/Changpu or similar aromatic, but text says Muxiang which is Litsea/Aucklandia root, often confused in ancient texts or referring to specific variety. Standard Muxiang is Aucklandiae Radix*), *Aquilariae Lignum Resinatum* (Chenxiang), *Foeniculum Vulgare* (Huixiang), and *Notopterygii Rhizoma et Radix* (Qianghuo). These were cut into pieces totaling one tael and half, intended for administration. Someone remarked, "All pains, itching, and sores belong to Heart Fire." Moreover, it is the height of summer heat; is it appropriate to use Ganjiang and Fuzi? I replied, "It is logically correct." The *Neijing* states: "Fine pulse, cold skin, diarrhea before and after, inability to eat—this is called the 'Five Deficiencies'. Hiccups indicate extreme deficiency of Stomach Qi." Although it is a general principle that all swellings and sores belong to Heart Fire, this case presents contradictory internal and external manifestations. One must abandon the seasonal convention and follow the syndrome. Without urgent treatment using a large dose of pungent and hot agents, recovery is impossible. Thus, the medicine was administered, all symptoms disappeared, food intake resumed, the sore became warm, and the pus color normalized. Yan He then administered Wuxiang Tang (Five Fragrances Decoction) for several doses, and the patient recovered fully after more than a month. Alas! Adhering to conventions is the view of the masses; knowing how to adapt is crucial for major matters. Those who know the constant but fail to understand adaptation often suffer defeat, especially in medicine. Can adhering to convention and knowing adaptation be compared on the same day?
