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。

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.
