论述一篇，方剂二十一首。
论述说：治疗香港脚（脚气病）要顺应四季变化，如果在春秋两季发病，应当兼顾补益和泻实；夏季病情容易迅速形成，必须专门采用发汗和利小便的方法；十月以后应少用补药。虽然病情有细微变化，但不超出这个法则。
治疗香港脚初发，从足部起病直至膝盖和小腿肿胀，骨骼疼痛的方剂：
取胡麻叶，切碎，捣烂，蒸熟，薄薄地包裹患处，每天更换两次，肿胀即可消退。如果是冬季，取蒴藋根切碎，捣烂，与三分酒糟、一分蒴藋根混合，一起蒸热，像前面所述的方法包裹。
全身肿胀，小便涩滞不通的，用麻豆汤主治的方剂：
大麻子（二升，炒熟，研磨） 乌豆（一斗，用水四斗半煮取汁一斗半，去掉豆子） 桑白皮（切碎，五升）
以上三味药，用豆汁加入药物，煮取六升药液，每次服用一升，每天服用两次，三天内服完。
又一方：牛尿，每次服用一升，每天两次，肿胀消退后停药。身体虚弱消瘦的人，用二分尿、一分牛奶，混合煮沸，待牛奶表面浮起结成薄膜时，再服用。
又一方：生猪肝一个，细细切碎，用淡蒜泥蘸着吃完。如果一次吃不完，分两次吃完。
治疗腰脚疼痛的方剂：
胡麻子（一斗，新鲜的）
以上一味药，炒至香味溢出，捣碎过筛。如果不多次过筛，油脂会流出而药粉无法通过。每天服用一小升，每天三次，服完一斗药的汁液，疾病即可永远痊愈。可以用酒送服，也可以用羹汤或蜜水送服。
在大泻下之后四肢虚寒，脚中虚弱无力，腰部拘挛疼痛，饮食减少，皮肤肌肉疏松虚浮的，石斛酒的方剂：
生石斛（一斤） 秦艽 远志（各五两，去心） 橘皮 白术（各三两） 丹参 茯神 五加皮（各六两） 桂心（四两） 牛膝（八两）
以上十味药，切碎，用酒三斗，浸泡七天，每次服用六合，逐渐增加到七八合，以见效为度。
调理通利之后尚未平复，偶尔被外风侵袭，脚中疼痛酸楚转为香港脚的，补虚防风汤的方剂：
防风 石斛 杜仲（炙） 前胡（各四分） 薏苡仁（半斤） 秦艽 丹参 五加皮 附子（炮制，去皮） 橘皮 白术 白前（各三分） 防己（二分） 麻仁（一升，炒熟取油）
以上十四味药，切碎，用水一斗二升，煮取三升药液，分三次服用。
服用汤药后香港脚仍然不止的，防风丸的方剂：
防风（二两） 秦艽（二两） 石斛（二两） 丹参（一两） 薏苡仁（三合） 前胡 橘皮 杜仲（炙） 附子（炮制，去皮） 白术（各一两） 桂心（一两半） 麻仁（一升，炒熟取油）
以上十二味药，捣碎过筛成粉末，炼蜜调和制成梧桐子大小的丸药，用酒送服二十丸，每天两次。
治疗香港脚经常发作，用谷白皮粥来预防，按照此法就不会发作的方剂：
谷白皮（五升，切碎，不要选取有斑点的，因为有毒）
以上一味药，用水一斗，煮取七升药液，去掉渣滓，用来煮米粥经常食用。
Treatise: One Article; Formulas: Twenty-One Articles
The treatise states: To treat Hongjiao (Foot Qi disease), one must conform to the four seasons. In spring and autumn, tonification and purgation should be employed concurrently. In summer, the condition tends to develop rapidly, requiring exclusive use of diaphoresis (sweating) and diuresis (promoting urination). After the tenth month, tonifying medicines should be used sparingly. Although there may be minor variations in symptoms, the treatment principles do not deviate from this method.
Formula for early-stage Hongjiao starting from the feet and extending to the knees and shins with swelling and bone pain:
Take Sesame leaves (Sesamum indicum leaves), chop them, pound them, steam them, and apply thinly to the affected area. Change the dressing twice daily until the swelling subsides. If treating in winter, take the roots of Dioscorea bulbifera (Shuoyang root), chop them, pound them, and mix with three parts fermented grain residue (jiuzao) and one part Dioscorea bulbifera root. Steam the mixture until hot and apply as described above.
For generalized swelling and difficult urination, the primary formula is Mahou Tang (Hemp Bean Decoction):
Cannabis seeds (Dama), two sheng, roasted and ground; Black soybeans (Wudou), one dou, boiled in four and a half dou of water to yield one and a half dou of juice, beans discarded; Mulberry bark (Sangbaipi), chopped, five sheng.
Combine the three ingredients with the soybean juice and boil to obtain six sheng of decoction. Take one sheng per dose, twice daily. Complete the course within three days.
Another formula: Cattle urine, one sheng per dose, twice daily. Discontinue when swelling subsides. For emaciated patients, mix two parts cattle urine with one part cow's milk, boil together until a skin forms on the surface, then consume.
Another formula: One raw pig liver, finely chopped. Consume entirely with mild garlic paste. If it cannot be consumed at once, divide into two doses.
Formula for treating waist and foot pain:
Sesame seeds (Huma), one dou, fresh.
Roast the single ingredient until fragrant, pound, and sieve. Sieve repeatedly to ensure the oil does not escape but the powder passes through. Take one small sheng per dose, three times daily. Finish one dou of the medicinal juice, and the disease will be permanently cured. It can be taken with wine, soup, or honey water.
Formula for Shihu Jiu (Dendrobium Wine) for post-purgation weakness with cold limbs, weak legs, spasmodic lower back pain, reduced appetite, and loose skin and flesh:
Fresh Dendrobium stem (Shihu), one jin; Gastrodia rhizome (Qinjiao); Polygala root (Yuanzhi), each five liang, heart removed; Tangerine peel (Jupi); Atractylodes macrocephala rhizome (Baizhu), each three liang; Salvia miltiorrhiza root (Danshen); Poria sclerotium (Fushen); Five-leaf Acanthopanax bark (Wujiapi), each six liang; Cinnamon twig heart (Guixin), four liang; Achyranthes bidentata root (Niuxi), eight liang.
Chop the ten ingredients, soak in three dou of wine for seven days. Take six he per dose, gradually increasing to seven or eight he, until therapeutic effect is achieved.
Formula for Buxu Fangfeng Tang (Tonifying Deficiency and Wind-Expelling Decoction) for Hongjiao characterized by lingering pain and soreness in the feet after regulation, triggered by external wind invasion:
Saposhnikovia root (Fangfeng); Dendrobium stem (Shihu); Eucommia bark (Duzhong), processed; Peucedanum root (Qianhu), each four fen; Coix seed (Yiyiren), half a jin; Gastrodia rhizome (Qinjiao); Salvia miltiorrhiza root (Danshen); Five-leaf Acanthopanax bark (Wujiapi); Aconite lateral root (Fuzi), processed and peeled; Tangerine peel (Jupi); Atractylodes macrocephala rhizome (Baizhu); Cynanchum stenosiphon root (Baiqian), each three fen; Podocarpus root bark (Fangji), two fen; Hemp seed (Maren), one sheng, roasted for oil extraction.
Chop the fourteen ingredients, boil in twelve sheng of water to obtain three sheng of decoction. Divide into three doses.
Formula for Fangfeng Wan (Wind-Expelling Pill) if Hongjiao persists after taking decoctions:
Saposhnikovia root (Fangfeng), two liang; Gastrodia rhizome (Qinjiao), two liang; Dendrobium stem (Shihu), two liang; Salvia miltiorrhiza root (Danshen), one liang; Coix seed (Yiyiren), three ge; Peucedanum root (Qianhu); Tangerine peel (Jupi); Eucommia bark (Duzhong), processed; Aconite lateral root (Fuzi), processed and peeled; Atractylodes macrocephala rhizome (Baizhu), each one liang; Cinnamon twig heart (Guixin), one and a half liang; Hemp seed (Maren), one sheng, roasted for oil extraction.
Pound and sieve the twelve ingredients into powder. Mix with refined honey to form pills the size of mulberry seeds. Take twenty pills with wine, twice daily.
Preventive recipe using Gu Baipi Porridge for recurrent Hongjiao to prevent attacks:
Rice bran (Gu Baipi), five sheng, chopped. Do not use spotted grains as they are toxic.
Boil the single ingredient in one dou of water to obtain seven sheng of liquid. Strain and use the liquid to cook rice porridge. Consume regularly.
