夫伤寒之说，始自黄帝以开其端，至于仲景方陈其条目，自后肤浅之学，莫知其数。立言者只云病在表可
发汗，病在里可下，或云不可汗、不可下，未尝有温中之说。仲景《伤寒例》云∶尺寸俱沉细，太阴受病也；
尺寸俱沉，少阴受病也；尺寸俱微缓，厥阴受病也。又辨太阴症云∶太阴病脉浮，可发汗，宜桂枝汤。又手足

最是三阴病之良法，于今世用之，尚有未尽证者。愚常校之，自至和初岁迄于今三十余年，不以岁之太过、不
及为则，每至夏至以前，有病伤寒人十中七八，两手脉俱沉细数，多是胸膈满闷，或呕逆，或气塞，或肠鸣，
或腹痛，与仲景三阴病说理同而证不同，因兹不敢妄投仲景三阴药方。才见脉沉及胸膈满，便投下药下之，往
往不救。常斟酌仲景理中丸与服之，其病势轻者，胸中便快；其病势重者，半日许满闷依然。或有病患脉沉细
迟，投仲景四逆汤温之，多药力大热，后必发烦躁，因校量此形证，今别立方以治之，药多对证，不可不传焉。
病患但两手脉沉细数，或有力，或无力，或关脉短及力小，胸膈塞满，气短不能相接者，便可随脉证投温
中药以治之。病患两手脉沉迟，或紧，皆是胃中寒也。若寸脉短及力小于关尺者，此阴盛阳虚也。或胸膈满闷，
腹中胀满，身体拘急，手足逆冷，急宜温之。若立春以后至清明以前，宜温中汤主之。清明以后至芒种以前，

The theory of Shanghan (Cold Damage) began with the Yellow Emperor, who opened the way, and reached its systematic formulation by Zhang Zhongjing. Since then, superficial medical practices have been countless. Those who formulate theories only state that diseases in the exterior can be treated with sweating methods, and diseases in the interior can be treated with purgative methods, or that neither sweating nor purging is indicated; there has never been a discussion on "warming the middle." Zhang Zhongjing's *Shanghan Example* states: When both the Cun (inch) and Chi (cubit) pulses are deep and fine, it indicates Taiyin disease; when both are deep, it indicates Shaoyin disease; when both are slightly slow and moderate, it indicates Jueyin disease. Furthermore, regarding Taiyin symptoms, he clarifies: In Taiyin disease, if the pulse is floating, sweating may be applied, preferably using Guizhi Tang (Cinnamon Twig Decoction). He also states: If the hands and feet are warm, accompanied by spontaneous diarrhea without thirst, Sini Tang (Frigid Extremities Decoction) is appropriate. For abdominal fullness with intermittent pain, Guizhi Jia Shaoyao Tang (Cinnamon Twig Decoction plus Peony Root) is used. Regarding Shaoyin signs: At the onset of Shaoyin disease, if there is fever and a deep pulse, Mahuang Fuzi Xixin Tang (Ephedra, Aconite, and Asarum Decoction) is indicated. After two to three days of Shaoyin disease, Mahuang Fuzi Gancao Tang (Ephedra, Aconite, and Licorice Decoction) is used. If Shaoyin disease presents with cold hands and feet, body pain, joint pain, and a deep pulse, Fuzi Tang (Aconite Decoction) is prescribed. For Jueyin disease, characterized by vomiting, diarrhea, cold extremities, and severe irritability bordering on death, Wuzhuyu Tang (Evodia Decoction) is indicated. Additionally, in Shaoyin disease with a deep pulse, urgent warming is required, favoring Sini Tang. I cite several passages from Zhang Zhongjing’s discussions as excellent methods for treating the Three Yin diseases. However, applying them in contemporary times reveals incomplete coverage of certain syndromes.
I have observed and verified this over more than thirty years since the beginning of the Zhihe era, regardless of whether the annual climatic influence was excessive or deficient. Before the Summer Solstice, seven or eight out of ten patients suffering from Shanghan present with deep, fine, and rapid pulses in both hands. They commonly experience chest and diaphragm fullness and oppression, or vomiting and regurgitation, qi stagnation, borborygmus, or abdominal pain. While the underlying theory aligns with Zhang Zhongjing’s description of Three Yin diseases, the clinical manifestations differ. Therefore, I dare not recklessly administer Zhang Zhongjing’s formulas for Three Yin diseases. Physicians who see a deep pulse and chest fullness and immediately apply purgatives often fail to save the patient. I frequently prescribe Lizhong Wan (Regulate the Middle Pill) based on Zhang Zhongjing’s formula. For mild cases, the chest feels relieved quickly; for severe cases, the fullness persists after half a day. Some patients with deep, fine, and slow pulses were given Sini Tang for warming, but due to the excessive heat of the medication, they subsequently developed irritability. Weighing these clinical presentations, I have now formulated new prescriptions for treatment, which prove highly effective. These must be transmitted.
If a patient presents with deep, fine, and rapid pulses in both hands—whether forceful or weak—or a short Guan (bar) pulse with weak strength, accompanied by chest and diaphragm blockage and fullness, and shortness of breath where inhalation cannot connect smoothly, one should administer warming-middle herbs according to the pulse and syndrome. Deep and slow or tight pulses in both hands indicate Cold in the Stomach. If the Cun pulse is short and weaker than the Guan and Chi pulses, this signifies Yin Excess and Yang Deficiency. Symptoms such as chest and diaphragm fullness, abdominal distension, bodily stiffness, and cold extremities require urgent warming. From after Li Chun (Start of Spring) until before Qingming (Clear and Bright), Wenzhong Tang (Warm the Middle Decoction) is indicated. From after Qingming until before Mangzhong (Grain in Ear), Chenpi Tang (Tangerine Peel Decoction) is indicated. From after Mangzhong until before Liqiu (Start of Autumn), Qiwu Lizhong Wan (Seven-Ingredient Regulate-the-Middle Pill) is indicated.
Wenzhong Tang
Dingpi (Pericarpium Citri Reticulatae Viride, 1 liang), Ganjiang (Prepared Rhizoma Zingiberis, prepared), Baizhu (Rhizoma Atractylodis Macrocephalae), Chenpi (Pericarpium Citri Reticulatae), Dingxiang (Flos Caryophylli, each 2 qian), Houpo (Cortex Magnoliae Officinalis, 1 liang, processed).
Grind into fine powder. Take 2 qian per dose, decoct with one sheng of water, three cun of scallion white, and five spikes of Jingjie (Herba Schizonepetae) until reduced to 0.7 parts. Strain and take hot. If relief is not achieved and extremities remain cold with vomiting, add 2 qian each of Dingxiang and Ganjiang.
Chenpi Tang
Chenpi (1 liang), Huoxiang (Herba Agastaches, 3 qian), Baizhu, Gegen (Radix Puerariae, each 2 qian), Houpo (1 liang, processed).
Grind into powder. Take 2 qian per dose, decoct with one sheng of water and a piece of Shengjiang (Rhizoma Zingiberis Recens) until reduced to 0.7 parts. Strain and take hot. If unsatisfied after three doses, with persistent cold extremities and不定 vomiting, add Banxia (Rhizoma Pinelliae), Dingxiang, and Guizhi (Ramulus Cinnamomi) each 0.5 liang. Add three cun of scallion white per dose during decoction.

Consume the liquid and dregs hot. If unsatisfied after three doses, with cold extremities and vomiting, add 0.5 liang each of Banxia and Shengjiang.
If the patient’s pulses in both hands are deep, fine, and weak, even if the three positions (Cun, Guan, Chi) are equal in strength, it still indicates Excess Yin. There is no need to wait for a short Cun pulse to initiate treatment. Symptoms such as chest and hypochondriac fullness, bodily stiffness and pain, and cold extremities require prompt harmonization with warming-middle herbs. From after Li Chun until before Qingming, Houpo Wan (Magnolia Bark Pill) is indicated. From after Qingming until before Mangzhong, Baizhu Tang (Atractylodes Macrocephala Decoction) is indicated. From after Mangzhong until before Liqiu, Jupi Tang (Tangerine Peel Decoction) is indicated.

Grind into powder and mix with refined honey to form pills the size of a bullet. Take one pill per dose, decoct until reduced to 0.6 parts. Consume the liquid and dregs hot. If the pulse remains fine after three doses, or if the Cun pulse remains fine and weak, add three cun of scallion white per dose during decoction.
Baizhu Tang

Grind into powder. Take 3 qian per dose, decoct with one sheng of water and a piece of Shengjiang the size of a jujube until reduced to 0.7 parts. Strain and take hot. If after three to five doses the pulse remains small and extremities are cold, add 0.5 liang of Xixin.
When a patient experiences chest and diaphragm fullness, frequent vomiting and regurgitation, limb and joint pain, pain in both hypochondria, and borborygmus, this indicates retained fluid (Phlegm-Fluid). Er Ling Tang (Two-Poria Decoction) is indicated.
Chi Fuling (Poria Cum Radice, 0.5 liang each with Zhu Ling and Baizhu), Huashi (Talcum, 1 liang), Tongcao (Medulla Tetrapanacis), Baixiudoukou (Fructus Cardamomi Albii, each 2.5 qian), Dingxipi (Pericarpium Citri Reticulatae Viride, 7.5 qian), Chenpi (0.5 liang), Guizhi (5 qian).
