成氏明理论云。四逆者。四肢逆而不温也。四肢者。诸阳之本。阳气不足。阴寒加之。阳气不相顺接。是致手
足不温。而成四逆。此汤升发阳气。却散阴寒。温经暖肌。是以四逆名之。甘草味甘平。内经曰。寒淫于内。治以
甘热。却阴扶阳。必以甘为主。是以甘草为君。干姜味辛热。内经曰。寒淫所胜。平以辛热。逐寒正气。必先辛热。
是以干姜为臣。附子味辛大热。内经曰。辛以润之。开发腠理。致津液。通气也。暖肌温经。必凭大热。是以附子
为使。此奇制之大剂也。四逆属少阴。少阴者。肾也。肾肝位远。非大剂则不能达。内经曰。远而奇偶。制大其服。
此之谓也。

琥按上议君使药。实得仲景之旨。成氏以甘草分两特重。指以为君。殊欠斟酌。
少阴病。饮食入口则吐。心中温温欲吐。复不能吐。始得之。手足寒。脉弦迟者。此胸中实。不可下也。当吐
之。若膈上有寒饮。干呕者。不可吐也。急温之。宜四逆汤。（此条亦少阴中寒。当急温之证也。少阴病脉不微细。
庶几以但欲寐辩之。少阴之脉上膈。循喉咙。出络心。注胸中。寒邪直中其经。故饮食入口即吐。其有至心胸中者。
又温温欲吐。复不能吐。皆寒邪阻隔于胸咽之间。而气壅塞不通也。曰始得之。手足寒。正以辩其非传经热邪之证

真用吐法也。谓中寒之证。亦有口食寒物一条。使胸中果有寒物。不妨就其欲吐之势而吐之。若膈上所停之物止寒
饮。寒饮者。似痰而清。得辛热之药。实时便能消散。并非有物可以吐出。故但干呕。止有急温一法。宜四逆汤。
恐缓则不救耳。○愚按上条证用四逆汤。能温经散寒。补虚暖胃。○或问胃寒欲吐。何以不用理中汤丸。余答云。
理中之寒。寒在中焦。今者少阴病寒自下焦而起。肾虚不能约束水液。故上溢于膈而为寒饮。方用四逆汤者。使直

(This formula was collected from the second volume of Zhang Zhongjing's original treatise and compiled here.)
Gancao (Licorice Root, *Glycyrrhizae Radix et Rhizoma*, 2 liang, processed with honey/heat) Ganjiang (Dried Ginger, *Zingiberis Rhizoma*, 1.5 liang) Fuzi (Prepared Aconite Root Lateralis, 1 piece, used raw, skin removed, broken into eight pieces).
The above three ingredients. Coarsely crush. Add three sheng of water. Boil to obtain one sheng and two he. Remove the dregs. Divide into two doses and take warm. For robust individuals, a large Fuzi (one piece) and Ganjiang (3 liang) may be used.
Cheng Wuji stated in his *Ming Lilun* (Theory of Clarification): "Si Ni" refers to the reversal coldness of the four limbs, making them not warm. The four limbs are the root of all Yang meridians. When Yang Qi is insufficient and Yin-Cold pathogen attacks, Yang Qi fails to connect smoothly, resulting in cold hands and feet, thus forming the Si Ni syndrome. This decoction raises and generates Yang Qi, dispels Yin-Cold, warms the meridians, and warms the muscles; hence it is named Si Ni Tang. Gancao has a sweet and neutral flavor. The *Neijing* states: "When Cold invades internally, treat with Sweet-Hot methods." To repel Yin and support Yang, Sweet substances must be primary; therefore, Gancao serves as the Sovereign drug. Ganjiang has a pungent and hot flavor. The *Neijing* states: "When Cold prevails excessively, level it with Pungent-Hot methods." To drive out Cold and assist healthy Qi, Pungent-Hot agents must be used first; therefore, Ganjiang serves as the Minister drug. Fuzi has a pungent and greatly hot flavor. The *Neijing* states: "Pungent moistens by opening the interstices, distributing fluids, and promoting Qi circulation." To warm muscles and meridians, greatly hot properties are essential; therefore, Fuzi serves as the Envoy drug. This is an unconventional large-dose prescription. Si Ni belongs to Shaoyin disease. Shaoyin corresponds to the Kidney. The positions of Kidney and Liver are deep and distant; without a large dose, the medicinal power cannot reach them. The *Neijing* states: "When the disease site is distant and complex (odd/even), increase the dosage." This refers to such cases.
*Neitai Fangyi* states: For diseases in the exterior-Yang, Ge Gen Tang and Ma Huang Tang can be used for sweating. For diseases in the exterior-Yin, Gui Zhi Tang and Ma Huang Fuzi Xixin Tang can be used for sweating. For diseases in the interior-Yang, Xiao Cheng Qi Tang and Da Chai Hu Tang can be used for purging. For diseases in the interior-Yin, Si Ni Tang, Bai Tong Tang, and Zhen Wu Tang can be used for warming. Now, this Si Ni Tang is precisely used for diseases in the interior-Yin. The previous clause did not mention various symptoms of Shaoyin disease, only noting a deep pulse. A deep pulse indicates deficiency and collapse; lack of desire to drink water indicates Yin-Cold. Fuzi must be the Sovereign drug to warm the meridians and assist Yang; Ganjiang as the Minister assists; Gancao as the Envoy harmonizes these two drugs and disperses Cold. The *Neijing* states: "When Cold invades internally, treat with Sweet-Hot methods"; and again: "When Cold prevails excessively, level it with Pungent-Hot methods." These refer to the heat of Fuzi, the pungency of Ganjiang, and the sweetness of Gancao.
Hu notes: The above discussion on Sovereign and Envoy drugs truly captures the intent of Zhang Zhongjing. Cheng Wuji, because the dosage of Gancao was particularly heavy, designated it as the Sovereign drug, which is indeed insufficiently considered.
Shaoyin disease. Food vomited immediately upon entering the mouth, a sensation of warmth and nausea in the heart/chest with an urge to vomit but inability to do so. At the onset, cold hands and feet, and a string-taut and slow pulse indicate excess in the chest; purgation is contraindicated, and emesis should be induced. If there is cold fluid retention above the diaphragm causing dry retching, emesis is contraindicated; urgent warming is required, suitable for Si Ni Tang. (This clause also represents a case of Shaoyin middle-cold requiring urgent warming. Shaoyin disease pulses are not necessarily fine and weak; differentiation can be made via lethargy/desire to sleep. The Shaoyin meridian ascends through the diaphragm, follows the throat, connects to the heart, and enters the chest. Cold pathogen directly strikes its meridian, hence food is vomited immediately upon entry. When cold reaches the heart-chest, there is a warm nausea and urge to vomit but inability, all due to Cold pathogen blocking the chest-throat region, causing Qi stagnation and obstruction. "Onset with cold hands and feet" is to differentiate this from transmitted heat pathogens. Diagnosing the pulse as not fine/weak but slow indicates Cold. The presence of a string-taut pulse indicates chest excess and fluid retention. Generally, excess-heat conditions allow purgation, while excess-cold conditions do not. Saying "emesis should be induced" does not mean actually using emetic therapy; it refers to a type of middle-cold caused by eating cold food. If there is indeed cold matter in the chest, one might顺应 the urge to vomit to expel it. If the retention above the diaphragm is merely cold fluid (clear like phlegm), it dissipates instantly with Pungent-Hot medicine and is not tangible matter to be vomited. Thus, with only dry retching, only urgent warming is applicable, suitable for Si Ni Tang, lest delay render it incurable. ○ I note: The previous condition using Si Ni Tang can warm meridians, disperse cold, tonify deficiency, and warm the stomach. ○ Question: Why not use Li Zhong Tang/Wan for stomach cold with vomiting? Answer: Li Zhong treats cold in the Middle Jiao. Here, Shaoyin disease cold arises from the Lower Jiao; Kidney deficiency fails to control fluids, causing overflow to the diaphragm as cold fluid. Si Ni Tang is used to direct the action to the Lower Jiao to treat the root. ○ Doubt: Is honey-processed Gancao contraindicated for vomiting patients? Answer: Excess-heat vomiting with fullness/bloating contraindicates Gancao. Here, the chest has no excess, only deficient-cold Qi; the formula relies entirely on honey-processed Gancao to warm and tonify Middle Qi. Raw Fuzi travels to the Kidney to scatter Shaoyin meridian cold; Ganjiang guards the center and stops vomiting but does not tonify. Grasping the key principle, why hesitate? ○ Another question: With both vomiting and retching, can Sheng Jiang (Fresh Ginger) be added? This statement is theoretically sound.)
Shaoyin disease. Diarrhea with a faint and choppy pulse, vomiting with sweating, frequent bowel movements but scant output, should be treated with moxibustion on the upper body. (This clause describes the method of moxibustion for Shaoyin middle-cold. The Shaoyin pulse is naturally faint, indicating Yang deficiency. Due to diarrhea, the pulse becomes choppy, indicating blood deficiency caused by excessive loss of Yin through stool. Vomiting is counterflow of Cold Qi. Yang deficiency fails to secure the exterior, causing sweating. Yang Qi sinking leads to frequent bowel movements ("changing clothes" refers to defecation, see Vol 6 Yangming disease). Scant output despite straining indicates blood deficiency. Therefore, moxibustion is used to eliminate Yin-Cold and lift Yang Qi, stopping diarrhea and resolving all symptoms. ○ Note: Zhang Zhongjing did not specify which acupoint to moxa. *Mai Jing* suggests Jueyin Shu. *Bu Wang Lun* Chang Qizi suggests Taichong; both are errors. Guo Baiyun suggests Taixi; although a Shaoyin point, it is also an error. I believe "warm the upper" refers to the top of the head, Baihui. *Tu Jing* says: Baihui, also called San Yang Wu Hui, is 1.5 cun behind Qian Ding, at the center of the scalp hair whorl, space for a bean. Originally indicated for pediatric rectal prolapse, seven moxa cones can be applied. Moxa for the above condition lifts Yang to regulate Yin.)

The above twenty-seven conditions (seen in Volume 6, Shaoyin Disease Treatment Methods, Chapter 11 of the original treatise).
Shanghan presenting initially with Jue (cold extremities), followed by fever, the diarrhea will stop spontaneously. If Jue returns, diarrhea recurs. (This Shanghan condition is Jueyin middle-cold, characterized by linked Jue and diarrhea. Jueyin is the end of Yin. The Jueyin meridian has very little Yang Qi; thus, regardless of Yin or Yang syndromes, or Cold or Heat pathogens, once they enter this meridian, Jue occurs. Jue means reversal/cold extremities starting from hands and feet, spreading coldness throughout the body. "Initial Jue" means Jue occurs at onset. Jue accompanies diarrhea. As Cheng's commentary states: when Yin Qi prevails, Jue and diarrhea occur. Subsequent fever indicates Yang Qi recovery. Yang recovery causes spontaneous cessation of diarrhea. If mismanagement or mistaken use of cooling herbs causes Jue to return, diarrhea will recur because Yang is defeated and Yin prevails, leading to critical danger. ○ Note: Zhang Zhongjing provided no treatment method here. *Bu Wang Lun* Chang Qizi suggests Bai Tou Weng Tang. Guo Baiyun states Bai Tou Weng Tang treats heat-diarrhea; here, one must distinguish cold/heat. I consider the above condition to be Yin-Cold Jue-diarrhea; mild cases use Wu Zhu Yu Tang, severe cases Si Ni Tang. ○ I further note: "Initial Jue then fever" implies Jue and diarrhea occurred at onset, indicating non-transmission from Yang meridians. Yang meridian pathogens cause heat first, then Jue. If diarrhea occurs, heat pathogen is expelled, preventing Jue. Thus, simultaneous Jue and diarrhea must be Yin-Cold. ○ Question: Can Yang syndromes present with initial cold extremities followed by fever? Answer: Yang syndromes show headache etc.; during Jue, the body is hot. There is no case of isolated Jue lasting days without fever. However, heat pathogen transmitting to Jueyin can cause severe Jue with whole-body cold, indistinguishable from Yin syndromes. Clinicians must differentiate carefully.)
Shanghan with a slow pulse, persisting for six to seven days, yet mistakenly given Huang Qin Tang to clear heat. Slow pulse indicates Cold. Giving Huang Qin Tang removes heat, causing abdominal coldness and anorexia. The patient now eats voluntarily; this is called Chu Zhong (Elimination of the Middle), indicating certain death. (This Shanghan condition is Jueyin middle-cold, fatal due to mistaken cooling medication. Slow pulse indicates Cold, obvious to any. Mistakenly giving Huang Qin Tang at day six/seven implies the illness started with Jue and diarrhea. By day six/seven, Yang recovered, causing transient fever while diarrhea persisted. Unskilled physicians saw fever and diarrhea, mistook it for Taiyang-Shaoyang combined disease, and used Huang Qin Tang to clear heat ("Che" means remove). Explaining the error: Abdominal coldness means no Stomach Fire. No Stomach Fire implies anorexia. Voluntary eating here is Chu Zhong. Chu Zhong means the rootless Yang Qi in the Stomach is nearly exhausted, seeking salvation through food before being completely eliminated; hence, certain death. ○ I note: Jueyin Shanghan has Heat-Chu Zhong (previous clause). This Jueyin middle-cold has Cold-Chu Zhong. All diseases must be distinguished by Yin/Yang and Cold/Heat, not confused.)
Shanghan initial Jue, subsequent fever, diarrhea stops spontaneously. Instead, sweating occurs and throat pain develops; the throat becomes Bi (obstructed). Fever without sweating, diarrhea stops spontaneously; if it does not stop, pus and blood appear in stool. If pus and blood appear, the throat is not obstructed. (This condition is Jueyin middle-cold where Yang recovery transforms into Heat, leading to throat Bi and bloody stool. Initial Jue then fever stops diarrhea (see Clause 1). However, excessive Heat from Yang recovery causes sweating and throat pain, injuring Upper Jiao Qi. "Bi" means closure; severe throat pain causes throat obstruction because the Jueyin meridian passes behind the throat and enters the nasopharynx. Excessive Heat without sweating and persistent diarrhea causes pus/blood in stool, injuring Lower Jiao Blood. Heat venting downward spares the upper, hence no throat Bi. ○ Note: Zhang Zhongjing gave no treatment. *Bu Wang Lun* Chang Qizi suggests Jie Geng Tang for Bi and Tao Hua Tang for bloody stool, borrowed from Shaoyin treatments. However, Tao Hua Tang contains Ganjiang, too pungent/hot, and should not be used. Although originally middle-cold, Yang recovery turned it to Heat, fermenting into pus/blood, distinct from Shaoyin middle-cold bloody stool. In *Shanghan Lun*, Zhongjing's Huang Qin Tang could be borrowed. ○ Question: Why does middle-cold transform to heat? Answer: Those with sufficient Yuan Qi resist deep invasion; Cold stays on the surface causing fever (Shanghan). Those with deficient Yuan Qi suffer direct strike to Yin meridians without fever (Zhonghan). Cold striking Jueyin (extreme Yin) generates Yang (Ji Yin Ze Yang Sheng), causing fever. Recovery depends on Yuan Qi. Mild deficiency allows recovery via fever. Severe deficiency leads to death via Jue alone (True Yang collapse). Fever with persistent Jue requires hot herbs to support Yang. Fever leading to Bi/bloody stool (as above) indicates Yang recovery is excessive, unable to overcome pathogenic Heat, requiring cooling herbs to pacify. I suspect this condition resulted from overusing hot herbs during Jue. Clinicians must differentiate carefully.)
Shanghan disease: Jue for five days, fever for five days. If on the sixth day Jue should return but does not, the patient heals spontaneously. Jue never exceeds five days because fever lasted five days; thus, spontaneous healing is known. (This condition is Jueyin middle-cold where Yang recovers and heals spontaneously. Equal duration of Jue and fever, with no recurrence of Jue, indicates True Yang prevails and Yin-Cold scatters, confirming spontaneous healing.)
Shanghan with faint pulse and Jue, progressing to day seven or eight with cold skin. The patient is restless with no moment of peace; this is Zang Jue (Organ Jue), not Hui Jue (Roundworm Jue). Hui Jue patients vomit roundworms. The patient is usually quiet but experiences intermittent vexation; this is Zang Cold. Roundworms ascend to the diaphragm, causing vexation. It stops after a moment, returning to quietness. Eating causes vomiting and renewed vexation because roundworms smell food and emerge; the patient vomits roundworms. Hui Jue is treated with Wu Mei Wan. It also treats chronic diarrhea. (This Shanghan condition distinguishes Zang Jue from Hui Jue in middle-cold. Both have faint pulse and Jue. In Zang Jue, by day seven/eight, skin is cold (whole body muscle cold), and restlessness with no peace indicates Kidney True Yang forced by Cold, with spirit about to collapse. This is Shaoyin Zang Jue, an incurable condition, unlike Jueyin Hui Jue. Hui Jue involves vomiting roundworms. The patient is normally quiet; Jueyin Liver struck by Cold causes intermittent vexation as roundworms disturb the diaphragm. Quietness returns briefly, contrasting with Zang Jue's constant restlessness. Eating causes vomiting/vexation as roundworms seek food warmth in a cold stomach. Wu Mei Wan warms the organ and calms worms. It treats chronic diarrhea because roundworms exit via stool in chronic cases. ○ Note: Zhang Zhongjing gave no treatment for Zang Jue. *Bu Wang Lun* Pang Anshi suggests Si Ni Tang taken cold. Chang Qizi suggests Dang Gui Si Ni Tang.)
