脉
香港脚之脉,其状有四∶浮弦为风,宜汗;濡弱湿气,宜渗;迟涩因寒,宜温;洪数为热,宜下。微
滑者虚,牢坚者实。结则因气,散则因忧,紧则因怒,细则因悲。
病
夫香港脚者,古谓之缓风,又谓之厥者,是古今之异名也。有干、湿之分,其脚肿者,名湿香港脚;其不
肿者,名干香港脚。由脾胃两经虚弱,行动坐卧之间,为风寒暑湿之气所侵,或内因饮食浓味所伤,致湿热下
注而成。如得之不便觉,乃因他病发动而知,先从
脚起,或先缓弱痹,或行起忽倒,或两胫肿满,或足膝枯细,或心下松悸,或小腹不仁,大小便涩,或
举体转筋,骨节酸痛,或恶闻食气,见食吐逆,或胸满气急,憎寒壮热,状似伤寒,是其候也。
或经一旬,或半月复作,渐而至于足筋肿大如瓜瓠者。
治
治之之法,用苍术、白术以治其湿,黄芩、黄拍、知母以治其热,当归、芍药、生地黄以调其血,木瓜、
槟榔以调其气,羌活、独活以利关节而散风湿,兼用木通、防己、牛膝引诸药下行,及消肿去湿,以为此证
之大法矣。兼用针HT 导引其湿热之气外出也。东垣曰∶湿淫所胜,治以苦温,以苦辛发之,透关节,胜
湿为佐,以苦寒泄之,流湿清热为臣。故立当归拈痛汤治之,其效捷于影响,学人更宜详究焉。
一、凡脚肿,名湿香港脚,用五积散加槟榔、木瓜、青藤、穿山甲。
一、凡足疼痛,皮不肿赤,筋不拘急,遇夜则痛甚,此是气虚,而血不荣也。宜十全大补汤,加牛膝、
木瓜、槟榔、石南藤、五加皮、没药、川乌之类,或四斤丸。若两膝赤肿,强急作热而掣痛,两总
筋拘急,此血热也,宜人参败毒散加赤芍药、大黄,利气丸下之。
一、凡香港脚上攻,胸膈闷满,大便不通,宜三和散。
一、凡香港脚攻注,大小便不通,用水中大螺蛳三个,以盐一小撮,和壳生捣烂,
置两脐下一寸三分,用帛紧紧系之,立通神效。
一、凡两膝肿痛,脚胫枯细,名曰鹤膝风,以四物汤加黄
、人参、白术、附子、牛膝、杜仲、防风、羌活、甘草。又宜五积散加松节、林节。

脉象
香港脚(即脚气病)的脉象,主要有四种表现:浮弦脉主风邪侵袭,适宜用发汗法治疗;濡弱脉主湿气内盛,适宜用渗湿利水法治疗;迟涩脉主寒邪凝滞,适宜用温里散寒法治疗;洪数脉主热邪炽盛,适宜用泻下法治疗。微滑脉提示正气虚弱,牢坚脉提示邪气实盛。结脉多因气机郁结所致,散脉多因忧思过度所致,紧脉多因愤怒伤肝所致,细脉多因悲伤耗气所致。
病症
所谓香港脚,古代称为“缓风”,又被称为“厥”,这是古今名称的不同。它有干证和湿证之分,脚部肿胀的,称为湿香港脚;不肿胀的,称为干香港脚。这是由于脾胃两经虚弱,在坐卧行走之间,受到风寒暑湿等外邪侵袭,或者因为内在饮食厚味损伤,导致湿热下注而形成。如果起初没有明显感觉,往往是因为其他疾病发作时才知晓,症状通常先从脚部开始,有的先出现肢体弛缓无力或麻木,有的行走时突然跌倒,有的双侧小腿肿胀饱满,有的足膝肌肉萎缩枯细,有的心下部悸动不安,有的小腹部感觉迟钝,大小便排泄不畅,有的全身肌肉抽搐痉挛,骨节酸痛,有的厌恶食物气味,见到食物就呕吐逆反,有的胸部胀满、气息急促,憎恶寒冷且高热,症状类似伤寒,这就是其临床表现。有时经过十天或半个月后再次发作,逐渐发展到足部筋脉肿大像瓜瓠一样。
治法
治疗的方法,使用苍术、白术来治疗湿气,黄芩、黄柏、知母来治疗热邪,当归、芍药、生地黄来调理血液,木瓜、槟榔来调理气机,羌活、独活来疏通关节并疏散风湿,兼用木通、防己、牛膝引导诸药下行,以及消肿去湿,这是治疗此证的大法。同时配合针刺和导引疗法,使湿热之气排出体外。李东垣说:“湿气淫胜,应用苦温之品治疗,以苦辛之品发散,透达关节,以胜湿为佐助,以苦寒之品泄热,以流湿清热为臣药。”因此创立了当归拈痛汤来治疗,疗效迅速显著,学者们更应详细研究。
一、凡是脚部肿胀的,称为湿香港脚,使用五积散加槟榔、木瓜、青藤、穿山甲。
一、凡是足部疼痛,皮肤不肿不红,筋脉不拘急,到了夜间疼痛加剧,这是气虚而血不能荣养所致。适宜使用十全大补汤,加牛膝、木瓜、槟榔、石南藤、五加皮、没药、川乌之类,或者服用四斤丸。如果双膝红肿发热,僵硬拘急并牵引作痛,双侧总筋拘急,这是血热所致,适宜用人参败毒散加赤芍药、大黄,并用利气丸攻下。
一、凡是香港脚向上攻冲,胸膈闷满,大便不通,适宜使用三和散。
一、凡是香港脚攻注,大小便不通,取水中螺蛳三个,加一小撮盐,连同壳一起生捣烂,敷在两脐下一寸三分处,用布紧紧系住,立刻通畅,神效无比。
一、凡是双膝肿痛,小腿枯细,名为鹤膝风,使用四物汤加黄芪、人参、白术、附子、牛膝、杜仲、防风、羌活、甘草。也适宜使用五积散加松节、林节(应为椿根皮或类似药材,原文如此)。

Pulse Diagnosis
The pulse manifestations of Hongxiangjiao (Jiaogi disease, commonly known as beriberi or gouty arthritis in ancient texts) present four main patterns: A floating and wiry pulse indicates wind pathogen invasion, suitable for diaphoresis (sweating method); a soggy and weak pulse indicates dampness retention, suitable for diuresis (damp-draining method); a slow and choppy pulse indicates cold stagnation, suitable for warming the interior; a surging and rapid pulse indicates heat excess, suitable for purgation. A slightly slippery pulse suggests deficiency, while a firm and hard pulse indicates excess. A knotted pulse is often due to qi stagnation; a scattered pulse is often due to excessive worry; a tight pulse is often due to anger; a thin pulse is often due to sorrow.
Symptoms
Hongxiangjiao was historically referred to as "Huanfeng" (Slow Wind) or "Jue" (Reversal/Cold Extremities), reflecting different nomenclatures across eras. It is categorized into dry and wet types: swelling of the feet defines Wet Hongxiangjiao, while non-swelling defines Dry Hongxiangjiao. This condition arises from weakness in the Spleen and Stomach meridians, where external pathogens such as wind, cold, summerheat, and dampness invade during daily activities like sitting, lying, walking, or standing. Alternatively, internal injury from rich and heavy dietary habits leads to damp-heat sinking downward. Initially asymptomatic, it may be discovered only when triggered by other illnesses. Symptoms typically begin in the feet, manifesting as flaccidity, weakness, or numbness; sudden collapse while walking; bilateral swelling of the shins; withered and thin foot and knee muscles; palpitations in the epigastrium; insensitivity in the lower abdomen; difficult urination and defecation; generalized muscle spasms; bone and joint soreness; aversion to food odors; nausea and vomiting upon seeing food; chest fullness and shortness of breath; aversion to cold accompanied by high fever, resembling Taiyang disease (Exterior Syndrome). These are the characteristic signs. The condition may recur after ten days or half a month, progressively leading to significant swelling of the foot tendons resembling gourds.
Treatment Principles
The general treatment principle involves using Cangzhu (Atractylodis Rhizoma) and Baizhu (Atractylodis Macrocephalae Rhizoma) to resolve dampness; Huangqin (Scutellariae Radix), Huangbai (Phellodendri Cortex), and Zhimu (Anemarrhenae Rhizoma) to clear heat; Danggui (Angelicae Sinensis Radix), Shaoyao (Paeoniae Radix), and Shengdihuang (Rehmanniae Radix) to regulate blood; Mugua (Chaenomelis Fructus) and Binglang (Arecae Semen) to regulate qi; Qianghuo (Notopterygii Rhizoma et Radix) and Duhuo (Angelicae Pubescentis Radix) to unblock joints and dispel wind-dampness; combined with Mutong (Akebiae Caulis), Fangji (Stephaniae Tetrandrae Radix), and Niuxi (Achyranthis Bidentatae Radix) to guide herbs downward, reduce swelling, and drain dampness. Additionally, acupuncture and Dao Yin (therapeutic exercises) should be employed to expel damp-heat. Li Dongyuan stated: "When dampness prevails excessively, treat with bitter-warm agents; use bitter-pungent agents to disperse and penetrate the joints; employ bitter-cold agents to purge and drain dampness while clearing heat." Thus, Danggui Nian Tong San (Danggui Pain-Relieving Powder) was formulated, showing rapid efficacy. Scholars are advised to study this thoroughly.
1. For cases with foot swelling (Wet Hongxiangjiao), use Wuji San (Five Accumulations Powder) supplemented with Binglang (Arecae Semen), Mugua (Chaenomelis Fructus), Qingteng (Uncariae Ramulus cum Uncis), and Chuanshanjia (Manis Squama).
2. For foot pain without skin redness or swelling, and without tendon spasm, but worsening at night, this indicates Qi deficiency failing to nourish Blood. Use Shiquan Dabu Tang (Ten Significant Tonifying Decoction) supplemented with Niuxi (Achyranthis Bidentatae Radix), Mugua (Chaenomelis Fructus), Binglang (Arecae Semen), Shinanteng (Acanthopanacis Senticosi Caulis), Wujapi (Acanthopanacis Cortex), Moyao (Myrrha), and Chuanwu (Aconiti Radix Preparata), or Sijin Wan (Four Jin Pill). If both knees are red, swollen, hot, stiff, and painful with traction, and the major tendons are spasmodic, this indicates Blood Heat. Use Renshen Baidu San (Ginseng Detoxification Powder) supplemented with Chishaoyao (Paeoniae Radix Rubra) and Dahuang (Rhei Radix et Rhizoma), followed by Liqi Wan (Qi-Regulating Pill) to purge.
3. For Hongxiangjiao attacking upward causing chest and diaphragm fullness and constipation, use Sanhe San (Three Harmonizations Powder).
4. For Hongxiangjiao attack with obstruction of urination and defecation, take three freshwater snails, mix with a pinch of salt, crush them raw including the shells, apply to one cun three fen below both umbilicus points, and bind tightly with cloth. This provides immediate and miraculous relief.
5. For bilateral knee swelling and pain with withered shins, termed Hexikeng Feng (Crane Knee Wind), use Siwu Tang (Four Substances Decoction) supplemented with Huangqi (Astragali Radix), Renshen (Ginseng Radix), Baizhu (Atractylodis Macrocephalae Rhizoma), Fuzi (Aconiti Lateralis Radix Preparata), Niuxi (Achyranthis Bidentatae Radix), Duzhong (Eucommiae Cortex), Fangfeng (Saposhnikoviae Radix), Qianghuo (Notopterygii Rhizoma et Radix), and Gancao (Glycyrrhizae Radix et Rhizoma). Also suitable is Wuji San (Five Accumulations Powder) supplemented with Songjie (Pinus Joint) and Linjie (likely referring to a specific bark or joint herb).
