内者，性命之道；经者，载道之书。其书乃黄帝与岐伯、鬼臾区、伯高、少师、少俞、雷公六臣，讲求而
成。其方高简奥妙，不易测识。今人罕能用之者。然既为古圣之神方，自不得不录之于首。（《成方切用》）
泽术麋衔散
有病身热解堕，汗出如浴，恶风少气，病名酒风。治之以泽泻、术各十分，麋衔五分，合以三指撮，为后
饭。（《素问》）
酒风，即《风论》曰∶饮酒中风，则为漏风。其伤在脾胃。病身热懈惰，汗出如浴，恶风少气。内因酒湿
所伤，则邪留肌肉；外因风邪伤卫，则阳气去，腠理疏，元府开，筋痿弱。是证之所由来也。麋衔祛在表之风；
泽泻渗在里之湿；白术助脾胃之气以却邪。合以三指撮者，是为散，欲其缓于中以去病也。后饭者，即仲景云∶
服药已，啜热稀粥，以助药力也。（《古方选注》）
兰草汤
有病口甘者，病名脾瘅。此肥美之所发也。肥者，令人内热；甘者，令人中满。其气上溢，传为消渴。治
之以兰，除陈气也。（《素问》）
省头草，花叶俱香，燥湿不变。脾瘅是有余之疾，必其人数食甘美而多肥，惟此清蔬，可除脾经陈久蕴蓄
之热。盖其味辛性
寒，主开结利窍，解热止渴，故以一味单行，能使肥甘不化之气，荡涤无余，则其性之峻利可知。苟非肥美所
发之瘅，又非所宜也。（《古方选注》）
鸡矢醴
有病心腹满，旦食而不能暮食，病名鼓胀。治之奈何？治之以鸡矢醴，一剂知，二剂已。（《素问》）
醴，甜酒也。少曲多米，酿之一宿而成者佳。鸡无前阴，溺屎同窍，佐以桃仁、大黄微利，水湿从大便而
出。清酒为熟谷之气，达于皮毛，行于脉络，下通水道。鸡屎与醴同行，复能使水湿从小便而出，二便通利，腹
胀潜消矣。（《古方选注》）
四乌 骨一 茹丸
有病胸胁支满，妨于食。病至则先闻臊腥臭，出清液，先唾血，四肢清，目眩，时时前后血，病名血枯。
此得之年少时有所大脱血，若醉入房，中气竭及伤肝也。肝伤，故月事衰少不来也。治之以四乌 眉，一 茹，
丸以雀卵，大如小豆，以五丸为后饭，饮以鲍鱼汁，利肠中。（《素问》）
乌 骨丸，皆血肉之品。盖血枯气去，苟非有情之物，焉能留恋气血而使之生长？乌 鱼骨，咸温下行，
性涩去脱，久服令人有子，可知其固气益精之功矣。 茹咸酸入肝，活血通经，疏气行伤。丸以雀卵，壮阳益
血。药后即饭，复饮鲍鱼汁，厌其药性下行，利肠续绝。每用五丸者，《经》言脱血入房，肝伤由于中气之竭，
故欲其留顿中宫，仍从脾胃转输于下也。（《古方选注》）
生铁落饮
有病怒狂者，生于阳也。阳气者，暴折而难决。病名阳厥，夺其食则已。夫食入于阴，长气于阳，使之服
以生铁落饮者，下气疾也。（《素问》）
厥阳怒狂，治之不以药石者，《经》言∶药石发癫，芳草发狂。故以生铁落，用水研浸为饮。盖铁之生者，
气寒味辛，其性
直行而降，下气疾速，用其捶出之花，遮得外走经络，开结于木火之中，则狂怒自已。（《古方选注》）
熨药方

除矣。刺后起步于密室中，欲其气血行，而慎避风寒也。（《成方切用》）
豕膏
痈发于嗌中，名曰猛疽。猛疽不治，化为脓。脓不写，塞咽，半日死。其化为脓者，写则合豕膏冷食，
三日已。（《灵枢》）
猛疽，言为害之急也。豕膏，即猪脂之炼净者也。（《成方切用》）

邪客于手、足少阴、太阴、足阳明之络，此五络皆会于耳中，上络左角。五络俱竭，令人身脉皆动，而
形无知也。其状若尸，名曰尸厥。剃其左角之发方一寸燔治，饮以美酒一杯，不能饮者，灌之立已。（《灵枢》）
邪客于四脏一腑之络，乃为尸厥者，以心肾为水火络；肺脾为天地络；胃为中土络。此五络皆会于耳中，
上络左角。若阴阳相离，不能交会，则身脉动而形无知，其状如尸。当刺五络之井，不已，先以竹管吹耳，以
通五络之会。再剃其左角之发，燔为血余，入络化淤，饮以美酒，使络气与卫气相通，庶阳和厥醒。（《古方选注》）
半夏秫米汤
厥气客于五脏六腑，则卫气独卫其外，行于阳不得入于阴。行于阳则阳气盛，阳气盛则阳跷陷。不得入
于阴，阴虚故目不瞑。补其不足，泻其有余，调其虚实，以通其道，而去其邪。饮以半夏汤一剂，阴阳已调，

[Background Information]
Book: Yi Shu (Records of Medicine)
Author: Cheng Xingxuan
Dynasty: Yuan (Note: Historically Qing, but transcribed as per original text)
Chapter: Neijing Fanglun (Commentary on Formulas from the Inner Canon)
Category: Medical Discourse
The "Nei" refers to the fundamental principles of life and destiny; the "Jing" is the book that records these principles. This work was compiled through extensive discussion among the Yellow Emperor and his six ministers: Qibo, Guiyuzhou, Bogao, Shaoshi, Shaoyu, and Leigong. The formulas contained therein are lofty, concise, profound, and subtle, making them difficult to comprehend and master. Few people today can effectively utilize them. However, since they are the divine prescriptions of ancient sages, it is imperative to record them at the beginning of this volume. (From *Chengfang Qieyong*)
**Zeshu Mixian San (Alisma, Atractylodes, and Daphne Decoction Powder)**
There is a condition characterized by fever, physical exhaustion and flaccidity, profuse sweating resembling a bath, aversion to wind, and shortness of breath. This disease is named "Jiu Feng" (Wine Wind). It is treated with Zexie (Alismatis Rhizoma) and Baizhu (Atractylodis Macrocephalae Rhizoma), each in ten parts, and Mixian (Daphnes Genkwa Cortex) in five parts. These are mixed and taken as a powder, measured by three fingers ("San Zhi Cuo"), administered after meals. (From *Suwen*)
"Jiu Feng" refers to what is described in the *Feng Lun* (Discourse on Wind): contracting wind after drinking alcohol results in "Lou Feng" (Leaking Wind). The injury lies in the Spleen and Stomach. Symptoms include fever, lethargy, profuse sweating, aversion to wind, and qi deficiency. Internally, the damage is caused by dampness from alcohol, causing pathogens to linger in the muscles; externally, wind pathogens injure the Defensive Qi (Wei Qi), leading to the dissipation of Yang Qi, laxity of the interstices (Cou Li), opening of the Yuan Gates (sweat pores), and flaccidity of the sinews. This explains the origin of the syndrome. Mixian expels wind from the exterior; Zexie leaches out dampness from the interior; Baizhu assists Spleen and Stomach Qi to expel pathogens. "San Zhi Cuo" indicates the preparation as a powder, intended for slow action in the Middle Jiao to resolve the disease. "Hou Fan" (after meal) corresponds to Zhang Zhongjing's instruction: after taking medicine, drink hot thin porridge to assist the medicinal power. (From *Gufang Xuanzhu*)
**Lancao Tang (Orchid Herb Decoction)**
There is a condition where the mouth tastes sweet, named "Pi Dan" (Spleen Heat/Excess). This arises from excessive consumption of rich and fatty foods. Fatty foods generate internal heat; sweet foods cause abdominal fullness. The qi overflows upward, transmitting into Xiao Ke (Wasting and Thirsting Syndrome). It is treated with Lancao (Eupatorii Herba) to eliminate stale turbid qi. (From *Suwen*)
Shentou Cao (Peilan, Eupatorium fortunei), with fragrant flowers and leaves, maintains its drying-dampness efficacy. "Pi Dan" is an excess syndrome, typically occurring in individuals who frequently consume sweet, delicious, and fatty foods. Only such clearing vegetables can remove the long-standing accumulated heat in the Spleen meridian. Its flavor is pungent and nature cold, primarily opening knots, benefiting orifices, resolving heat, and quenching thirst. Therefore, used singly, it can thoroughly cleanse the qi of undigested rich and sweet foods, revealing its potent and penetrating nature. If the condition is not caused by rich food-induced heat, this formula is not suitable. (From *Gufang Xuanzhu*)
**Jishi Li (Chicken Dropping Sweet Wine)**
There is a condition with fullness in the heart and abdomen, where one can eat in the morning but cannot eat in the evening, named "Gu Zhang" (Drum Distension/Tympanites). How should it be treated? Treat with Jishi Li. One dose brings improvement; two doses bring recovery. (From *Suwen*)
"Li" refers to sweet wine, made with a small amount of yeast starter and large amounts of rice, brewed overnight for best results. Chickens lack a separate anterior yin orifice; urine and feces share the same passage. Combined with Taoren (Persicae Semen) and Dahuang (Rhei Radix et Rhizoma) to mildly promote bowel movement, water-dampness exits via the stool. Clear wine represents the qi of cooked grains, reaching the skin and hair, circulating in the collaterals, and descending to unblock the water pathways. Jishi (Gallus Gallus Domesticus Brisson Faeces) combined with wine enables water-dampness to exit via urination. With both bowels and bladder unblocked, abdominal distension gradually dissipates. (From *Gufang Xuanzhu*)
**Si Wuie Gu Yi Ru Wan (Four Parts Cuttlebone and One Part Rubia Pill)**
There is a condition with support-like fullness in the chest and hypochondrium, interfering with eating. Upon onset, the patient first smells a fishy odor, secretes clear fluid, expectorates blood, experiences cold limbs, dizziness, and frequent bleeding from the anterior and posterior orifices. This disease is named "Xue Ku" (Blood Depletion). It originates from significant blood loss in youth, or sexual activity while intoxicated, leading to exhaustion of Middle Qi and Liver injury. Liver injury causes menstrual scarcity or amenorrhea. Treatment uses four parts Wuwie Gu (Sepiae Endoconcha) and one part Ru (Rubiae Radix et Rhizoma), formed into pills using Quelian (Quail Egg), sized like small beans. Take five pills after meals, washed down with Baoyu Zhi (Abalone Juice) to benefit the intestines. (From *Suwen*)
Wuweigu Wan consists of "flesh-and-blood" substances. Since blood is depleted and qi is lost, only living substances can retain and nourish blood and qi. Wuwie Gu is salty and warm, descending in nature, astringent to stop leakage; long-term use promotes fertility, demonstrating its ability to consolidate qi and benefit essence. Ru is salty and sour, entering the Liver, activating blood, unblocking meridians, regulating qi, and repairing injury. Quilian strengthens Yang and benefits blood. Taking medicine followed by food, then Baoyu Zhi, suppresses the downward action of the herbs, benefits the intestines, and reconnects severed vessels. Taking five pills aligns with the Classic's statement that blood loss and sexual excess injure the Liver due to Middle Qi exhaustion; thus, the medicine is intended to stay in the Middle Jiao and be transported downward via the Spleen and Stomach. (From *Gufang Xuanzhu*)
**Shengtie Luo Yin (Raw Iron Drop Drink)**
There is a condition of anger and mania, arising from Yang. Yang Qi suffers sudden obstruction and difficulty in resolution. This disease is named "Yang Jue" (Yang Reversal); depriving the patient of food cures it. Food enters the Yin and generates Yang Qi; therefore, administering Shengtie Luo Yin works because it rapidly descends qi. (From *Suwen*)
For Jue Yang causing anger and mania, treatment does not rely on herbal medicines, as the Classic states: mineral drugs may induce epilepsy, and aromatic herbs may induce mania. Thus, Shengtie Luo (Raw Iron Drops) is ground in water and drunk. Raw iron has a cold qi and pungent taste, with a direct descending nature, rapidly descending qi. Using the hammered fragments covers the outward path of the collaterals, resolving knots within Wood and Fire, thereby stopping mania and anger. (From *Gufang Xuanzhu*)
**Yiyao Fang (Moxibustion/Warming Compress Formula)**
The Yellow Emperor asked: How to introduce heat when treating Cold Bi with acupuncture? Bogao answered: For commoners, use fire-quenching (moxibustion). For nobles, use warming compresses. Use twenty jin of pure wine, one sheng of Shujiao (Sichuan Pepper), one jin of Jiangjiang (Dried Ginger), and one jin of Guixin (Cinnamon Twig Heart). All four ingredients are chopped and soaked in wine. Add one jin of cotton wadding and forty zhang of fine white cloth, immersing them together. Place in a pit burning dry horse dung, seal and plaster tightly to prevent leakage. After five days and nights, remove the cloth and cotton, sun-dry the cotton, soak again until all juice is extracted. Each soaking must last seven days. Remove and mix the dregs with cotton, wrapping in cloth to make strips six to seven chi long, creating six or seven compresses. Heat the compresses with raw mulberry charcoal and apply to the acupoints treated for Cold Bi, ensuring heat penetrates to the lesion site. When cool, reheat and apply. Repeat thirty times. Wipe sweat with the cloth, also thirty times. Walk indoors immediately after, avoiding wind. Apply compress after every acupuncture session. Thus, the disease will heal. (From *Lingxu*)
"Ju" means chopping ingredients to the size of soybeans before decocting to extract clear liquid. "Zi" means soaking. "Ma Shi Wei Zhong" means simmering over burning dry horse dung. "Tu" means sealing with salt mud. "Xun" means a week. "Fu Bu Wei Jin" refers to modern pouches used to hold cotton and herb dregs. "Zi" refers to dregs. Heating cloth with raw mulberry charcoal utilizes Mulberry's ability to benefit joints and expel wind-cold-damp Bi. Nobles have clear and smooth blood and qi; therefore, before and after acupuncture, warming compresses alone can unblock meridians, induce sweating, and eliminate Cold Bi. Walking in a sealed room post-acupuncture promotes qi and blood circulation while avoiding wind-cold. (From *Chengfang Qieyong*)
**Shi Gao (Pork Fat Ointment)**
An abscess developing in the throat is named "Meng Ju" (Fierce Jar). If untreated, Meng Ju turns into pus. If pus is not drained, blocking the throat leads to death within half a day. For those who have turned to pus, draining it and applying Shi Gao (Porci Adeps) while cold, eaten cold, cures it in three days. (From *Lingxu*)
"Meng Ju" describes the urgency of the harm. "Shi Gao" refers to refined pig fat. (From *Chengfang Qieyong*)
**Qiaocao Gen Tang (Forsythia Root Decoction)**
An abscess developing in the hypochondrium is named "Bai Ci". "Bai Ci" is a disease affecting women. Treat with moxibustion. If it becomes a large abscess with pus, treat it. Inside, there may be new flesh growth, sized like a red adzuki bean. Chop Conggen (Scallion Root) and Qiaocao Gen (Forsythiae Caulis/Radix) each one sheng. Boil in one dou six sheng of water until reduced to three sheng. Force the patient to drink it thickly, wrap warmly, sit over a pot to steam, inducing sweating down to the feet. The disease resolves. (From *Lingxu*)
"Ji" refers to Water Caltrop. "Qiao" refers to Forsythia. The roots of both herbs detoxify. Ma Yuantai stated: "Ji" is now known as Forsythia. (From *Chengfang Qieyong*)
**Jiafa Jiu (Hair Wine)**
Pathogenic factors invade the collaterals of Hand-Shaoyin, Foot-Shaoyin, Hand-Taiyin, Foot-Taiyin, and Foot-Yangming. These five collaterals converge in the ear and ascend to connect with the left corner of the head. If all five collaterals are exhausted, the body's pulses move, but the form remains unconscious. The state resembles a corpse, named "Shi Jue" (Corpse Reversal). Shave one square cun of hair from the left corner, burn it, and administer with a cup of fine wine. If unable to drink, force-feed; recovery is immediate. (From *Lingxu*)
When pathogenic factors invade the collaterals of the Four Zang and One Fu, causing Shi Jue, it is because Heart and Kidney are the Water-Fire collaterals; Lung and Spleen are Heaven-Earth collaterals; Stomach is the Central Earth collateral. These five collaterals converge in the ear and ascend to the left head corner. If Yin and Yang separate and fail to intersect, pulses move while consciousness is lost, resembling a corpse. Acupuncture the Jing-Well points of the five collaterals. If ineffective, first blow air into the ears with a bamboo tube to open the convergence of the five collaterals. Then shave the left corner hair, burn it into Xuè Yú Tàn (Burnt Hair Ash), enter the collaterals to transform stasis, and drink fine wine to allow Collateral Qi to communicate with Wei Qi, harmonizing Yang and reversing Jue. (From *Gufang Xuanzhu*)
**Banxia Shumi Tang (Pinellia and Millet Decoction)**
Jue Qi lodges in the Five Zang and Six Fu, causing Wei Qi to guard only the exterior, circulating in Yang without entering Yin. Circulating in Yang makes Yang Qi abundant; abundant Yang Qi causes the Yang Qiao vessel to sink/stagnate. Inability to enter Yin leads to Yin deficiency, resulting in insomnia (eyes unable to close). Tonify deficiency, sedate excess, regulate emptiness and fullness, unblock the pathway, and expel pathogens. Administer Banxia Tang; once Yin and Yang are regulated, sleep returns immediately. (From *Lingxu*)
Ancient treatments for the Extraordinary Vessels relied solely on acupuncture, lacking herbal formulas. Now, with Jue Qi lodging in the Zang-Fu, Wei Qi circulates only in Yang, Yang Qiao Qi is abundant, and it cannot enter Yin, causing Yin deficiency and insomnia. Banxia Shumi Tang is used because herbs cannot directly enter the Yang Qiao vessel; thus, treating the Stomach drains Wei Qi. Banxia is pungent and warm, entering the Stomach Qi level; Shumi (Glutinous Millet) is sweet and sour, entering the Stomach Blood level. Water from a thousand miles stirred ten thousand times is light and ascending, not aiding Yin pathogens. Cooking with reed fuel involves strong fire initially, then gentle simmering to reduce, embodying ascending-descending methods. Ascending via Banxia opens Yang to vent Wei and expel pathogens; descending via Shumi enters Yin to nourish Ying and tonify deficiency. With Yin and Yang connected, sleep returns immediately. (From *Gufang Xuanzhu*)
**Magao Shensang Guijiu (Horse Fat, Raw Mulberry, and Cinnamon Wine)**
Spring Bi (spastic paralysis) is treated with Magao (Horse Fat). For severe spasticity, apply Baijiu (White Spirit) mixed with Guixin (Cinnamon Twig) to the affected area; for flaccidity, use a Mulberry Hook to stretch it. Place raw mulberry ash in a pit, adjusted to sitting height. Apply fat to the spasmodic cheek, drink fine wine, eat roasted meat. Non-drinkers should still eat meat. Pat lightly three times. (From *Lingxu*)
"Jichun Bi" refers to true wind-stroke in northern regions. Pathogens strike the Yangming collaterals, causing sudden facial deviation. Spasticity prevents eye closure; heat causes sinus flaccidity and inability to open eyes. Due to the dry, windy climate of the north, pungent dispersants are insufficient. External application of warming and moistening methods is required. Magao is sweet, pungent, soft, and slow, massaging spasticity, moistening blood vessels, and unblocking Bi. Flaccid sinews cannot contract, so Guixin's pungent heat and wine's meridian-unblocking property are applied to the flaccid side to harmonize Ying and Wei and unblock blood collaterals. The Mulberry Hook stretches the cheek. "Kan" refers to the depression in the cheek. Raw mulberry ash comes from live branches, possessing sharp potency to open joints and expel wind-Bi. Height adjusted to sitting ensures even distribution of ash for effective heat penetration. Magao soothes sinews and moistens Bi. "San Fu" means light patting three times. Fine wine promotes the action of herbs for upper-body diseases. Roasted meat aids Stomach Qi to ascend to the collaterals. (From *Gufang Xuanzhu*)
**Xiao Jindan (Little Golden Pill)**
Chensha (Cinnabar) two liang, Xionghuang (Realgar) one liang, Cihuang (Orpiment) one liang, Zijin (Purple Gold) half liang. Mix in a crucible. Seal externally. Bury one chi deep in the earth, compacting the soil. Do not use a furnace or other processing agents. Fire for seven days. Wait for cooling, remove the crucible, bury the medicine in the earth for seven more days. Remove, grind clockwise for three days. Form pills with honey, sized like wu zi (bayberries). Every morning, face east, inhale one breath of solar energy. Swallow one pill with ice water, harmonizing qi as you swallow. Ten pills prevent epidemic interference. (From *Suwen*)
Grinding with gold foil facilitates fine powder. Grinding clockwise refers to rotating left. (Commentary by Xu Lingtai)
Note: This text is from a lost chapter, added by later authors. The method is not ancient and should not be trusted blindly. (From *Chengfang Qieyong*)
