石膏（一两） 白术（半两） 麻黄（七钱半） 附子（半个） 甘草（二钱）
香港脚痛肿，寒热相搏，脉来沉细者，此方主之。
气不得通则痛，血不得行则肿，此香港脚之所以为壅疾也。寒热相搏者，邪气与正气相激
搏也。脉来沉者为里，细者为阴。名曰越婢者，越，以发越为义。婢，卑也。是方能发越
至卑之气，故以越婢名之。石膏性寒而重，寒能胜热，重能就下。附子味辛而热，辛能行壅，
热能壮气。佐之以麻黄，则寒热之壅，皆从汗孔而泄矣。用白术、甘草，取其气味温平，能
致冲和之气于发越之余耳。而甘草独少者，恐其性缓，多之不能速达于卑下之区也。
附子 桂心 防己（各四钱） 甘草（炙，二钱） 白术 茯苓（各三钱）
水煎冷服。
寒湿香港脚，疼痛不仁，两尺脉来沉细者，此方主之。
此痹证也。《内经》曰∶寒气胜者为痛痹，湿气胜者为着痹。今疼痛不仁，是寒而且着
也。两尺主两足，脉来沉者为里，迟者为寒。是方也，用桂心、附子温其寒。防己、白术制
其湿。甘草、茯苓，脾家药也，扶土气之不足，制湿气之有余。然必冷服者，欲附、桂之性
行于下，而不欲其横于上也。
川椒（一两） 葱（一握） 姜（如掌大一块，槌碎）
水一盆，煎汤洗之。
凡人患寒湿香港脚，疼痛不体者，内服煎剂，外宜以此汤熏洗之。
川椒辛热，能疗寒湿之痹。姜、葱辛温，能利肌肤之气。又曰∶诸香港脚者，皆壅疾也，
洗之无有不良。
石膏（一两） 白术（半两） 麻黄（七钱半） 附子（半个） 甘草（二钱）
香港脚（足胫肿痛之病）疼痛肿胀，寒热邪气相互搏结，脉象沉细的，此方主治。
气机不通畅则疼痛，血液运行不畅则肿胀，这就是香港脚之所以成为壅滞之疾的原因。寒热邪气相互搏结，是指邪气与正气相互激荡搏击。脉象沉主病在里，脉象细则属阴。命名为“越婢汤”，“越”是发越的意思，“婢”意为卑微低下。此方能发越至为卑下之气，所以用“越婢”来命名。石膏性寒而质重，寒能清热，重能引药下行。附子味辛而性热，辛能行散壅滞，热能壮阳益气。佐以麻黄，那么寒热造成的壅滞，都能从汗孔发散出去。使用白术、甘草，是取它们气味温平的特性，能在发越之余，使体内恢复冲和之气。而甘草用量独少，是担心它药性缓和，如果量多就不能迅速到达卑下部位。
附子 桂心（肉桂之心） 防己（各四钱） 甘草（炙，二钱） 白术 茯苓（各三钱）
用水煎煮，冷服。
寒湿型香港脚，疼痛且肢体麻木不仁，双侧尺脉沉细的，此方主治。
这是痹证（经络闭塞不通之病）。《内经》说：寒气偏胜的叫痛痹，湿气偏胜的叫着痹。现在疼痛且麻木不仁，说明既有寒邪又有湿邪滞留。两尺脉主要反映双足的情况，脉沉主病在里，脉迟主寒。此方中，用桂心、附子来温散寒邪。用防己、白术来制约湿气。甘草、茯苓是调理脾胃的药物，扶助脾土之气不足，制约湿气有余。然而必须冷服，是想让附子、桂心的药性下行作用于下部，而不希望它们横逆上行。
川椒（一两） 葱（一握） 姜（如手掌大的一块，捣碎）
用水一盆，煎汤熏洗患处。
凡是患有寒湿型香港脚，身体疼痛不适的，内服煎剂的同时，外用此汤熏洗。
川椒辛热，能治疗寒湿引起的痹证。姜、葱辛温，能宣通肌肤的气机。又说：所有的香港脚，都是壅滞之疾，熏洗没有不好的效果。

For Hongjiaojiao (Hongjiaojiao, a disease characterized by swelling and pain in the lower legs and feet) with pain and swelling, where cold and heat pathogens struggle against each other, and the pulse is deep and fine, this formula is indicated.
When Qi fails to flow smoothly, there is pain; when Blood fails to circulate, there is swelling. This is why Hongjiaojiao becomes a disease of stagnation. The struggling of cold and heat refers to the conflict between pathogenic factors and healthy Qi. A deep pulse indicates an interior condition, and a fine pulse indicates Yin deficiency or dampness. It is named "Yuebi Tang" (Yuebi Decoction). "Yue" means to vent or disperse; "Bi" means humble or low. This formula can vent Qi that is stuck in the lowest parts of the body, hence the name. Shigao is cold in nature and heavy in texture; its coldness clears heat, and its heaviness guides it downward. Fuzi is acrid and hot; its acridity moves stagnation, and its heat strengthens Qi. With Mahuang as an assistant, the stagnation caused by cold and heat will be discharged through the sweat pores. Baizhu and Gancao are used for their warm and neutral properties, to restore harmonious Qi after the dispersing action. Gancao is used in a smaller amount because its mild nature might delay reaching the lower parts if used in large quantities.

Decoct in water and take cold.
For cold-damp Hongjiaojiao with pain and numbness, and bilateral Chi pulses that are deep and fine, this formula is indicated.
This is a Bi syndrome (Obstruction Syndrome). The *Neijing* states: When Cold predominates, it is called Painful Bi; when Dampness predominates, it is called Fixed Bi. Now, with pain and numbness, it indicates both Cold and Dampness. The Chi pulses govern the feet; a deep pulse indicates interior pathology, and a slow pulse indicates Cold. In this formula, Guixin and Fuzi are used to warm and dispel Cold. Fangji and Baizhu are used to control Dampness. Gancao and Fuling are spleen-targeting herbs; they support the insufficiency of Spleen Earth Qi and restrain the excess of Dampness. However, it must be taken cold so that the properties of Fuzi and Guixin act downwards without ascending transversely upwards.

Use one basin of water, decoct to make a soup for washing.
For anyone suffering from cold-damp Hongjiaojiao with painful and uncomfortable limbs, besides taking internal decoctions, external fumigation and washing with this soup is suitable.
Chuanjiao is acrid and hot, capable of treating Bi syndromes caused by cold-damp. Jiang and Cong are acrid and warm, capable of promoting the flow of Qi in the skin and muscles. It is also said: All cases of Hongjiaojiao are diseases of stagnation; washing them yields no bad results.
