此亦痿症。如不起床席已成废人者，内火炽盛以熬干肾水也。苟不补肾，惟图降火，亦
无生机。虽治痿独取阳明，是胃火不可不降，而肾水尤不可不补也。今传一奇方，补水于火

补丹。熟地、玄参、麦冬各一两，甘菊花、生地、沙参、地骨皮各五钱，车前子二钱，台党

足，自能制胃中之热，两相济而两相成，起痿之
功，孰有过于此者乎。
又方∶羊肾酒（见妇人科种子门）最为神妙。
又方∶用栗子二个（又名板栗，要二个俱扁者，若一面圆一面扁者食之不效），于四更

足软不能步履，人以为肾水之亏，不知非肾也，盖气虚不能运用耳。用补中益气汤（见
内外备用诸方）加牛膝三钱，蜜制黄 一两，台党三钱，水煎服。四剂即能行走。此方内有
石斛一味，经名医删去，更见功效。
又方∶杜仲一两，半酒半水煎，连服数剂，三日能行，五日全愈。肾虚足软痛极者，服
此最效。
这属于痿证。如果患者长期卧床不起，已经沦为废人，这是因为体内火气炽盛，煎熬耗干了肾水。如果不补肾，只图降低火势，也没有生机。虽然治疗痿证的原则是“独取阳明”，即胃火不可不降，但肾水尤其不可不补。现在传授一个奇方，在火中补水，在水内降火，同时调理胃与肾，自然骨髓得以增添，燔热尽散，不用专门治疗痿证，痿证也能自愈。这个方子名叫降补丹。熟地黄、玄参、麦冬各一两，甘菊花、生地黄、沙参、地骨皮各五钱，车前子二钱，党参一钱，用水煎服。这个方子降中有补，补中有降，所以精妙。胃火不生，自然就不会耗伤肾中的阴液；肾水既已充足，自然能制约胃中的热气，两者相互济助而相互成就，起痿的功效，有谁比得上这个方子呢？
另一个方子：羊肾酒（见妇人科种子门）最为神妙。
又一个方子：用栗子两个（又名板栗，要选两个都是扁的，如果一面圆一面扁的，吃了没有效果），在四更天将水嚼碎融匀平复至足软不能步履，人以为肾水之亏，不知非肾也，盖气虚不能运用耳。用补中益气汤（见内外备用诸方）加牛膝三钱，蜜制黄 一两，台党三钱，水煎服。四剂就能行走。这个方子里有一味石斛，被名医删去后，功效更加显著。
又一个方子：杜仲一两，半酒半水煎煮，连续服用几剂，三天能行走，五天完全痊愈。肾虚导致足部软弱疼痛剧烈的，服用此方最见效。
This is also considered Wei syndrome (Wasting and Thirsting Syndrome). If the patient has been bedridden for a long time and become disabled, it is due to excessive internal fire boiling away the Kidney water. If one does not tonify the Kidney but only seeks to clear the fire, there will be no hope of recovery. Although the principle for treating Wei syndrome is to "solely take Yangming" (focus on the Stomach channel), meaning Stomach fire must be lowered, yet Kidney water must especially be replenished. Now, I transmit a miraculous formula: replenishing water amidst fire, and lowering fire within water, treating both the Stomach and the Kidney simultaneously. Naturally, the bone marrow will increase, and the blazing heat will dissipate; without specifically treating Wei syndrome, the syndrome will heal itself. The formula is named Jiangbu Dan (Descend and Tonify Pill). Prepared Rehmanniae Radix (Shudi), Scrophulariae Radix (Xuanshen), and Ophiopogonis Radix (Maidong) each weigh one tael; Chrysanthemi Flos (Ganjuhua), Raw Rehmanniae Radix (Shengdi), Glehniae Radix (Shashen), and Lycii Cortex (Digupi) each weigh five qian; Plantaginis Semen (Cheqianzi) weighs two qian; Codonopsis Radix (Taidang) weighs one qian. Decoct with water and take orally. This formula descends while tonifying, and tonifies while descending, which is why it is exquisite. When Stomach fire does not arise, it naturally will not consume the Yin in the Kidney; once Kidney water is sufficient, it can naturally control the heat in the Stomach. The two mutually assist and complete each other. Who could surpass this formula in its efficacy for restoring weakness?
Another formula: Sheep Kidney Wine (see Women's Department, Seed-Generating Section) is most miraculous.
Yet another formula: Use two chestnuts (also known as板栗, select two that are both flat; if one is round and one is flat, eating them will be ineffective). [Text fragment appears corrupted or incomplete here regarding preparation method]. Regarding feet so weak they cannot walk, people attribute it to a deficiency of Kidney water, unaware that it is not the Kidney, but rather Qi deficiency failing to function. Use Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) (see Internal and External Prepared Formulas) with added Achyranthis Bidentatae Radix (Niuxi) three qian, Honey-processed Polygonati Rhizoma (Huangjing) one tael, and Codonopsis Radix (Taidang) three qian. Decoct with water and take orally. After four doses, walking becomes possible. This formula originally contained Dendrobii Caulis (Shihu), which was removed by famous physicians, resulting in even greater efficacy.
Yet another formula: Eucommiae Cortex (Duzhong) one tael, decocted with half wine and half water. Take continuously for several doses. Walking is possible in three days, and full recovery in five days. For those with Kidney deficiency causing extreme pain and weakness in the feet, this formula is most effective.
Hong Kong foot (Tinea pedis/Charcot joint) swelling and pain, leg and foot weakness, and Jiu Feng Jiao (Alcoholic Foot) all manifest in the legs.
A piece of Cinnamomum camphora wood (Zhangmu), crushed into powder and decocted in soup. One tael of sediment from an old urine bucket (Yuantongsha), ground into powder, mixed with Chen Xiaofen (a type of starch/flour), and applied as a poultice to the hot, painful area. It possesses life-saving efficacy.
