论曰∶产后热闷、气上，转为香港脚者何？答曰∶产卧血虚生热，复因春夏取凉过多，
地之蒸湿，因足履之，所以着为香港脚。其状热闷掣 、惊悸心烦、呕吐气上，皆其候也。可
服小续命汤（方见本卷第八论）。两三剂必愈。若医者误以逐败血药攻之，则血去而疾益增
矣。
陈无择评曰∶香港脚固是常病，未闻产后能转为者。往往读《千金》见产妇多有此疾之语
，便出是证，文辞害意，概可见矣。设是热闷气上，如何便服续命汤？此药本主少阳经中风
，非均治诸经香港脚，要须根据香港脚方论、阴阳经络调之。此涉专门，未易轻论，既非产后要病
，更不繁引。
陈无择虽有此评，然小续命汤加减与之，用无不效。故《百问》云∶寒中三阳，所患必
冷，小续命汤主之。（加生姜汁最快）暑中三阴，所患必热，小续命汤。（去附子，减桂心一
半）大烦躁者，紫雪最良。（仆取《百问》中加减法，庶使后人均得治疗）如无紫雪用真薄
荷煎，冷水嚼下。
论曰∶产后遍身疼痛者何？答曰∶产后百节开张，血脉流散，遇气弱则经络、分肉之间
血多流滞；累日不散，则骨节不利，筋脉急引。故腰背不能转侧，手足不能动摇，身热头痛
也。若医以为伤寒治之，则汗出而筋脉动惕，手足厥冷，变生他病。但服趁痛散除之。
论曰：产后出现热闷、气逆上冲，进而转变为香港脚（一种以足胫肿重、软弱无力为主要表现的疾病）的原因是什么？回答说：产妇卧床休息时气血虚弱而生内热，又因在春夏季节贪凉过度，加之地面蒸腾的湿气通过双脚侵入体内，所以导致病邪滞留而形成香港脚。其症状表现为热闷感、肢体抽搐掣痛、惊恐心悸、心烦意乱、呕吐以及气逆上冲，这些都是该病的征候。可以服用小续命汤（方剂见本卷第八篇论述）。服用两三剂后必定痊愈。如果医生错误地使用攻逐瘀血的药物来治疗，那么血液耗损而疾病反而会加重。
陈无择评论说：香港脚固然是常见病症，但从未听说过产后会转变为香港脚的。往往是因为阅读《千金方》时看到关于产妇多有此疾的说法，便据此推断出这种证型，可见文辞误导了医理。如果是热闷气上，怎么能直接服用续命汤呢？此药原本主治少阳经中风，并非普遍适用于所有经络的香港脚，必须依据香港脚的专门论述，结合阴阳经络进行调理。这涉及专科知识，不容易轻易议论，既然不是产后的主要病症，就不再繁琐引用。
虽然陈无择有上述评论，然而对小续命汤进行加减化裁使用，没有不奏效的。所以《百问》中说：寒邪侵袭三阳经，所患之病必然偏冷，用小续命汤主治。（加入生姜汁效果最快）暑邪侵袭三阴经，所患之病必然偏热，用小续命汤。（去掉附子，减少桂心一半用量）若出现极度烦躁者，紫雪散最为适宜。（我选取《百问》中的加减方法，以便让后人都能得到治疗）如果没有紫雪散，可用真薄荷煎汤，用冷水送服嚼碎。
论曰：产后全身疼痛的原因是什么？回答说：产后全身关节开张，血脉流散，遇到气虚则经络、肌肉之间的血液容易停滞；长时间不散，就会导致骨节活动不利，筋脉拘急牵引。因此出现腰背不能翻身侧卧，手足不能随意动摇，身体发热、头痛等症状。如果医生将其当作伤寒来治疗，会导致汗出过多而使筋脉跳动震颤，手足厥冷，从而变生其他疾病。只需服用趁痛散即可消除病痛。
Translation:
The treatise states: What is the reason for postpartum heat oppression and qi rushing upward, transforming into Hong Kong gout (a disease characterized by swelling and heaviness of the lower legs and weakness)? The answer is: After childbirth, lying in bed leads to blood deficiency generating internal heat. Furthermore, due to excessive exposure to coolness during spring and summer, combined with the steaming dampness from the ground entering through the feet, the pathogen lodges and forms Hong Kong gout. Its manifestations include heat oppression, muscle twitching and pulling pain, fright palpitations, vexation, vomiting, and qi rushing upward; these are all its signs. One may take Xiao Xuming Tang (Decoction of Minor Continuation of Life) (see Formula 8 in this volume). Two or three doses will surely cure it. If a physician mistakenly uses drugs that purge stasis to attack it, the blood will be depleted and the disease will increase.
Chen Wuyue commented: Hong Kong gout is indeed a common disease, but I have never heard of it transforming from postpartum conditions. Often, reading *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold), one sees statements that many women after childbirth suffer from this disease, and thus deduces this syndrome. This shows how textual descriptions can harm the understanding of medical principles. If there is heat oppression and qi rushing upward, how can one simply administer Xuming Tang? This medicine originally treats wind-stroke of the Shaoyang channel, not all channels of Hong Kong gout indiscriminately. One must rely on the treatises on Hong Kong gout and regulate according to Yin and Yang channels. This involves specialized knowledge and is not easy to discuss lightly. Since it is not a critical disease of the postpartum period, further citation is unnecessary.
Although Chen Wuyue has this comment, modifying Xiao Xuming Tang and using it yields effective results without exception. Thus, *Baiwen* (Hundred Questions) states: When cold invades the Three Yang channels, the illness must be cold in nature, treated with Xiao Xuming Tang. (Adding ginger juice is fastest). When summer-heat invades the Three Yin channels, the illness must be hot in nature, treated with Xiao Xuming Tang. (Remove Fuzi [Prepared Aconite Root], reduce Rougui [Cinnamon Bark] by half). For those with extreme restlessness, Zixue Powder (Purple Snow Powder) is best. (I selected the modification methods from *Baiwen* so that later generations may receive treatment). If Zixue Powder is unavailable, decoct fresh Bohe (Menthae Haplocalycis Herba), chew it, and swallow with cold water.
The treatise states: What is the reason for generalized body pain after childbirth? The answer is: After childbirth, the joints open up, and blood vessels disperse. When qi is weak, blood stagnates in the meridians and between muscles. If this stagnation persists for days, joint movement becomes difficult, and sinews and vessels become tense and pulling. Therefore, one cannot turn or side over in bed, hands and feet cannot move freely, and there is body fever and headache. If a physician treats it as Shanghan (Cold Damage), sweating will occur, causing sinews and vessels to tremble, leading to cold extremities and the generation of other diseases. One should only use Chentong San (Powder for Hastening Pain Relief) to eliminate it.
