陈临川云∶凡头痛身热,肢节痛,大便秘,或呕逆而脚屈弱者,香港脚也。轻者可与
香苏散加木瓜、槟榔、生姜煎服,然后随证治之。要知有香港脚之人,先从脚起,或先缓
弱疼痹,或行起忽倒,或两胫肿满,或脚膝枯细,或心中忪悸,或小腹不仁,皮顽不知
疼痛,或举体转筋,或见食呕逆,恶闻食气,或胸满气急。或遍体酸痛,皆香港脚之候。黄
帝所谓缓风湿痹是也。顽弱为缓风,疼痛为湿痹。寒中三阳,所患必冷,小续命汤主之。
(煎成,入生姜自然汁最妙。)暑中三阴,所患必热,小续命汤去附子,减桂一半主之。大烦躁者,
紫雪最良。若无紫雪,以百合、薄荷煎冷水调服极妙。大便秘者,脾约丸、麻仁丸、三
和散主之。仍针灸为佳。服补药与汤淋洗,皆医家之大禁也。
夫妇人香港脚,与丈夫不同。男子则肾脏虚弱,为风湿所乘。女子以胞络气虚,为风
毒所搏。是以胞络属于肾也,肾主于腰脚,又肝脾肾三脏经络起于足十趾,若脏腑虚损,则
风邪先客于脚,从下而上,动于气,故名香港脚也。此皆由体虚,或当风取凉,或久坐卑
湿,或产后劳损,或恚怒悲伤肝,则心气不足,致月候不通。因其虚伤风毒,传入筋骨,
则令皮肤不仁,筋骨疼痛,肢体不随,筋脉拘挛,或时冷疼,或发肿满,或两脚痹弱,或
举体转筋,目眩心烦,见食呕吐,精神昏愦,肢节烦疼,小便赤黄,大便秘涩。如此证候,
其妇人香港脚,疗之与丈夫不同,以其气血不调,胎妊产损伤之。是以疗寡妇及尼与妻外家
殊别,即其义也。
〔薛〕严用和先生云∶前证初患不觉,因他病乃发,先从脚起,或缓弱痹痛不能行
履,或两胫肿满,或足膝细小,或心中怔忡,或小腹不仁,或举体转筋,或见食作呕,或
胸满气急,遍体酸痛,其脉浮而弦者,因于风。濡而弱者,因于湿。洪而数者,因于热。
迟而涩者,因于寒。男子由于肾气亏损,女子血海虚弱,七情所致。窃谓前证若足三阴
虚弱,用还少丹。(杂病虚劳。)若脾气虚寒,用八味丸。(杂病虚劳。)若饮食停滞,臀腿酸胀,浮
肿作痛,此脾气下陷,用六君子(杂病虚劳。)少加柴胡、升麻;不应,须用八味丸。若发热
口渴,月经不调,两腿无力,此足三阴血虚火燥,用六味、八味二丸兼服。前证西方之
人多患之,原素食乳酪,脾胃壅滞,胫足肿满。至于南方,亦有因膏粱浓味,湿热下注
而患者。故古人谓之壅疾,所用之方,多疏通发散之剂。然感于房劳过度,亏损三阴,治
法又当以固本为主。故六物附子,为元气虚弱,寒邪内侵之圣药。

陈临川说:凡是出现头痛、身体发热、四肢关节疼痛、大便秘结,或者呕吐逆气且脚部屈伸无力的,就是香港脚病。病情较轻的,可以用香苏散加入木瓜、槟榔、生姜煎煮后服用,然后根据具体证候进行治疗。要知道患有香港脚的人,病邪通常先从脚部发起,有的先表现为脚部迟缓无力、疼痛麻木,有的行走时突然跌倒,有的双侧小腿肿胀饱满,有的脚膝枯瘦细小,有的心中悸动不安,有的小腹部感觉迟钝(不知痛痒),皮肤僵硬不知疼痛,有的全身肌肉抽搐痉挛,有的见到食物就呕吐逆气,厌恶食物的气味,有的胸部胀满、呼吸急促。有的全身酸痛,这些都是香港脚的征候。这就是《黄帝内经》所说的“缓风湿痹”。迟缓无力属于缓风,疼痛属于湿痹。如果是寒邪侵入三阳经,患处的症状必定偏冷,用小续命汤主治。(煎好药液后,加入生姜自然汁效果最好。)如果是暑热之邪侵入三阴经,患处的症状必定偏热,用小续命汤去掉附子,将桂枝用量减半来主治。如果烦躁严重的,紫雪是最良的药物。如果没有紫雪,用百合、薄荷煎冷水调服也非常妙。大便秘结的,用脾约丸、麻仁丸、三和散主治。同时配合针灸治疗更佳。服用补益药物以及用汤药淋洗患处,都是医家的大忌。
妇女的香港脚病,与男子不同。男子是因为肾脏虚弱,被风湿之邪所乘袭。女子是因为胞络之气虚弱,被风毒之邪所搏结。因为胞络隶属于肾,肾主管腰部和脚部,而且肝、脾、肾三条经络都起于足十趾,如果脏腑虚损,那么风邪就会先客居于脚部,从下向上发展,扰动气机,所以名叫香港脚。这都是因为体质虚弱,或者迎风取凉,或者久坐低洼潮湿之地,或者产后劳损,或者愤怒悲伤伤及肝脏,导致心气不足,致使月经不通畅。因为体虚而受伤风毒,传入筋骨,就会导致皮肤麻木不仁,筋骨疼痛,肢体不能随意运动,筋脉拘挛抽搐,有时冷痛,有时肿胀饱满,有时双脚麻木无力,有时全身抽搐痉挛,头晕目眩,心烦意乱,见到食物就呕吐,精神昏沉困倦,四肢关节烦疼,小便赤黄,大便秘涩。像这样的证候,治疗妇女的香港脚与男子不同,因为她们的气血不调,且有胎孕、生产等损伤的因素。因此,治疗寡妇、尼姑与普通妻子的方法有所区别,就是这个道理。
〔薛己〕严用和先生说:前面的证候在初发时并不觉得明显,往往因为其他疾病才发作,病邪先从脚部发起,有的表现为脚部迟缓无力、麻木疼痛而不能行走,有的双侧小腿肿胀饱满,有的足膝细小,有的心中惊悸怔忡,有的小腹部感觉迟钝,有的全身肌肉抽搐痉挛,有的见到食物就作呕,有的胸部胀满、呼吸急促,全身酸痛。脉象浮而弦的,是因为风邪;脉象濡而弱的,是因为湿邪;脉象洪而数的,是因为热邪;脉象迟而涩的,是因为寒邪。男子是由于肾气亏损,女子是血海虚弱,由七情内伤所致。我认为,如果足三阴经虚弱,就用还少丹。(见杂病虚劳门)如果脾气虚寒,就用八味丸。(见杂病虚劳门)如果饮食停滞,臀部和大腿酸胀,浮肿作痛,这是脾气下陷,用六君子汤(见杂病虚劳门),稍加柴胡、升麻;如果无效,必须用八味丸。如果发热口渴,月经不调,双腿无力,这是足三阴经血虚火燥,用六味地黄丸和八味丸两方兼服。前面的证候西方人容易患病,原本素食乳酪,导致脾胃壅滞,小腿和足部肿胀饱满。至于南方,也有因为食用膏粱厚味,湿热下注而患病的。所以古人称之为“壅疾”,所用的方剂,多是疏通发散的药物。然而如果是因房事过度,亏损三阴经,治法又应当以固本为主。所以六物附子类方剂,是元气虚弱、寒邪内侵的圣药。

其余证候的方论,详见杂病本门。
Chen Linchuan stated: Whenever there is headache, feverish body, pain in the limbs and joints, constipation, or vomiting with weakness and flexion of the feet, this is Hongxiangjiao (Gouty Arthritis). For mild cases, Xiangsu San (Perilla and Cyperus Powder) can be administered with added Mu Gua (Chaenomeles Fruit), Bing Lang (Areca Seed), and Sheng Jiang (Fresh Ginger Decoction), followed by treatment according to the specific syndrome. It must be known that patients with Hongxiangjiao typically develop symptoms starting from the feet. Manifestations may include initial flaccidity, weakness, pain, and numbness; sudden collapse while walking; bilateral swelling and fullness of the shins; emaciation of the feet and knees; palpitations in the heart region; insensitivity in the lower abdomen; skin induration with loss of pain sensation; generalized muscle spasms; nausea and vomiting upon seeing food or smelling food odors; chest fullness and shortness of breath; or generalized soreness and pain throughout the body. All these are signs of Hongxiangjiao. This corresponds to what the Yellow Emperor described as "Huan Feng Shi Bi" (Flaccid Wind-Damp Bi Syndrome). Flaccidity and weakness constitute Huan Feng (Flaccid Wind), while pain constitutes Shi Bi (Damp Bi). If Cold pathogen invades the Three Yang meridians, the afflicted area will necessarily feel cold; Xiao Xuming Tang (Minor Continuation of Life Decoction) is the primary formula. (It is best to add fresh ginger juice after decoction.) If Summerheat pathogen invades the Three Yin meridians, the afflicted area will necessarily feel hot; Xiao Xuming Tang should be used without Fu Zi (Aconite Lateral Root) and with Gui Zhi (Cinnamon Twig) reduced by half. For severe restlessness, Zi Xue (Purple Snow) is most effective. If Zi Xue is unavailable, Bai He (Lily Bulb) and Bo He (Mint) decocted in cold water for administration is also excellent. For constipation, Pi Yue Wan (Spley-Restriction Pill), Ma Ren Wan (Hemp Seed Pill), or San He San (Three Harmonies Powder) are indicated. Acupuncture and moxibustion are highly recommended. Taking tonifying medicines and washing the affected parts with medicated decoctions are strictly prohibited by physicians.
Women's Hongxiangjiao differs from men's. In men, it arises from Kidney deficiency allowing Wind-Damp to invade. In women, it results from Qi deficiency in the Bao Luo (Uterine Collaterals) allowing Wind-Toxin to bind. Since the Bao Luo is affiliated with the Kidney, and the Kidney governs the waist and feet, and the meridians of the Liver, Spleen, and Kidney all originate at the ten toes of the feet, when the Zang-Fu organs are deficient, Wind pathogen first lodges in the feet, ascending from below and disturbing Qi, hence the name Hongxiangjiao. These conditions arise from physical weakness, exposure to wind while cooling off, prolonged sitting in damp lowlands, postpartum overexertion, or anger and sorrow injuring the Liver, leading to Heart Qi deficiency and obstruction of menstruation. Due to deficiency allowing Wind-Toxin to enter the sinews and bones, skin becomes insensitive, sinews and bones ache, limbs become immobile, sinews and vessels spasm, sometimes with cold pain, sometimes with swelling, sometimes with numbness and weakness in both feet, sometimes with generalized spasms, dizziness, irritability, vomiting upon seeing food, mental confusion, joint pain, dark yellow urine, and constipation. For such syndromes, treating women's Hongxiangjiao differs from men's due to Qi and Blood disharmony and injuries related to pregnancy, childbirth, etc. Thus, the treatment for widows and nuns differs from that for ordinary wives, which illustrates this principle.
[Xue Ji] Yan Yonghe stated: The aforementioned syndrome is often unnoticed initially and manifests due to other illnesses, starting from the feet. Symptoms may include flaccidity, weakness, numbness, and pain preventing walking; bilateral shin swelling; small feet and knees; palpitations; abdominal insensitivity; generalized spasms; nausea upon seeing food; chest fullness and shortness of breath; and generalized soreness. A floating and wiry pulse indicates Wind; a soggy and weak pulse indicates Damp; a surging and rapid pulse indicates Heat; a slow and choppy pulse indicates Cold. In men, it stems from Kidney Qi depletion; in women, from Blood Sea deficiency caused by emotional disturbances. I suggest that if the Three Yin meridians of the foot are deficient, use Hai Shao Dan (Restore Youth Pill) [see Miscellaneous Diseases: Deficiency and Emaciation]. If Spleen Qi is deficient and cold, use Ba Wei Wan (Eight-Ingredient Pill) [see Miscellaneous Diseases: Deficiency and Emaciation]. If food stagnation causes soreness and distension in the buttocks and thighs with edema and pain, indicating Spleen Qi sinking, use Liu Jun Zi Tang (Six Gentlemen Decoction) [see Miscellaneous Diseases: Deficiency and Emaciation], adding minor amounts of Chai Hu (Bupleurum Root) and Sheng Ma (Cimicifuga Rhizome); if ineffective, Ba Wei Wan is required. If fever, thirst, irregular menstruation, and leg weakness occur, indicating Blood deficiency and Fire dryness in the Three Yin meridians of the foot, use Liu Wei Di Huang Wan (Six-Ingredient Pill with Rehmannia) and Ba Wei Wan together. People in the West are prone to this condition due to a diet rich in dairy, causing Spleen and Stomach stagnation and shin/foot swelling. In the South, it occurs due to rich foods causing Damp-Heat pouring downward. Hence ancients called it "Yong Ji" (Stagnant Disease), using formulas that mostly promote circulation and dispersal. However, if caused by excessive sexual activity damaging the Three Yin meridians, treatment should focus on consolidating the root. Therefore, Liu Wu Fu Zi (Six-Ingredient Aconite) type formulas are sacred remedies for Yuan Qi (Original Qi) deficiency and internal invasion of Cold pathogen.
