〔大全〕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（方见杂病中风。）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，盖可见矣。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。
陈无择虽有此论，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。（加生姜汁更快。）暑中三阴，所患必热，小续命汤。（去附子，减桂一半。）
大烦躁者，紫雪最良。（予取《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

〔薛〕前证当补气血为主，佐以小续命汤、寄生汤。如不应，用大防风汤。一产

[From *Chan Yu Bao Qing Ji*] What is the reason for postpartum heat oppression, rebellious Qi rising, and transformation into Hongxiangjiao (Jiaogi / Foot Qi)? The answer is: After childbirth, lying in bed leads to blood deficiency generating internal heat. Furthermore, due to excessive cooling measures taken during spring and summer, the steaming dampness of the earth enters through the feet upon walking, thus manifesting as Hongxiangjiao. Its manifestations include a sensation of heat and oppression, muscle twitching, palpitations, irritability, vomiting, and rebellious Qi rising; these are all its signs. One may take Xiao Xuming Tang (Decoction for Minor Continuation, see Miscellaneous Diseases - Stroke) for two or three doses, and it will surely be cured. If a physician mistakenly uses drugs that purge stagnant blood to attack the condition, the loss of blood will cause the disease to increase further.
Chen Wuyue commented: Hongxiangjiao is indeed a common disease, but I have never heard of it transforming from the postpartum state. People often read *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold), seeing statements that many puerperae suffer from this disease, and thus deduce this syndrome. This shows how textual descriptions can mislead the meaning. If there is heat oppression and rebellious Qi, how can one directly administer Xuming Tang? This medicine originally treats Wind-Stroke of the Shaoyang Meridian, not all meridians' Hongxiangjiao uniformly. One must regulate according to the treatises on Hongxiangjiao, balancing Yin and Yang meridians. This involves specialized knowledge and is not easy to discuss lightly. Since it is not a critical postpartum disease, further citation is omitted.
Although Chen Wuyue has this argument, in practice, modifying and administering Xiao Xuming Tang yields efficacy without fail. Thus, *Baiwen* (Hundred Questions) states: When Cold invades the Three Yang meridians, the affliction must be cold; Xiao Xuming Tang governs it. (Adding ginger juice acts faster.) When Summerheat invades the Three Yin meridians, the affliction must be hot; Xiao Xuming Tang [remove Fuzi, reduce Guizhi by half]. For those with extreme restlessness, Zixue San (Purple Snow Powder) is best. (I selected the modification methods from *Baiwen* so that later generations may receive treatment.) If Zixue San is unavailable, use genuine Bohe (Menthae Haplocalycis Herba) decocted in cold water to chew and swallow. (Lou Quanshan commented: Various formularies prescribe taking it mixed equally with Siwu Tang.)
[Xue Ji] The aforementioned syndromes should primarily be treated by tonifying Qi and Blood, assisted by Xiao Xuming Tang and Duhuo Jisheng Tang. If ineffective, use Dafangfeng Tang. A certain puerpera suffered from the aforementioned syndrome and recovered after taking Duhuo Jisheng Tang. Later, it recurred; upon taking the previous formula, she sweated profusely like water, accompanied by trismus (lockjaw) and expectoration. I used Shiquan Dabu Tang (Decoction for Complete Great Tonification) to cultivate Qi and Blood, and she gradually improved. Subsequently, her dietary intake decreased daily, her body emaciated, and expectoration surged. This indicated decline of Mingmen Fire (Fire of the Gate of Life) and deficiency-cold of Spleen Earth. I used Bawei Wan (Eight-Ingredient Pill) and Jiawei Guipi Tang (Modified Restore the Spleen Decoction); various symptoms gradually receded, and muscle mass gradually regenerated.
Duhuo Jisheng Tang (Decoction for Nourishing the Liver and Kidneys with Angelica Pubescens) Treats deficiency of the Liver and Kidneys, or prolonged exposure to damp-cold environments, or washing feet while exposed to wind, causing damp-toxin to attack internally. Symptoms include flaccidity and weakness of both calves, spasmodic pain, bi-syndrome weakness, or purple/broken skin and flesh, with contracted and heavy feet and knees. It also specifically treats postpartum Hongxiangjiao.
