This volume discusses the correspondence between medicines and syndromes (Yao Zheng) as well as the methods for modifying prescriptions. The term "medicine-syndrome correspondence" refers to the syndrome indicated before a prescription name, such as "a certain prescription treats a certain disease." In Shanghan diseases, different syndromes may affect the same meridian, or the same medicine may treat two different syndromes. By categorizing and comparing these situations, one must clearly understand which syndromes belong to which meridians and which prescriptions treat which syndromes; only then can treatment be infallible. Furthermore, in the *Baiwen* (Hundred Questions), multiple prescriptions may be listed for a single syndrome. One must match the disease with the medicine and the medicine with the disease before administration. For example, in cases of diarrhea accompanied by epigastric fullness and stuffiness, prescriptions such as Shizao Tang (Ten Date Decoction), Dachaihu Tang (Major Bupleurum Decoction), Shengjiang Xiexin Tang (Ginger Heart-Draining Decoction), Gancao Xiexin Tang (Licorice Heart-Draining Decoction), Chishizhi Yuyuliang Tang (Cinnabar Barium Carbonate Decoction), and Guizhi Renshen Tang (Cinnamon Twig and Ginseng Decoction) are involved. Although all treat diarrhea with epigastric fullness, these prescriptions differ in their cold and hot natures. Carefully analyzing the medicine-syndrome correspondence ensures accurate treatment.
The section on "prescriptions and modification methods" states that Zhang Zhongjing's Shanghan prescriptions total 113. When the condition matches the prescription exactly, the original formula is used; if there are differences, modifications are made according to the syndrome. Ancients said, "Study formulas for three years, yet no disease can be cured; treat diseases for three years, yet no formula fits." This is often cited as a famous theory, but people fail to realize that rigidly applying fixed formulas leads to inconsistent results. Instead of blaming the formulas, they should recognize the need for modifications. Ancient physicians used medicines flexibly, like the turning of the Big Dipper, striking the target directly for rapid effect: one dose brings improvement, two doses bring cure. For instance, in Lizhong Wan (Regulate the Middle Pill), if Kidney Qi moves upward, Baizhu (Atractylodis Rhizoma) is removed; in Xiaochaihu Tang (Minor Bupleurum Decoction), if urination is difficult, Fuling (Poria) is added. This is because the Spleen dislikes dampness and the Kidney dislikes dryness; Baizhu treats dampness, while Fuling promotes water metabolism. Thus, Baizhu is removed when Kidney Qi moves, and Fuling is added when urination is difficult. By extrapolating from this, one understands that one cannot rigidly apply formulas but must modify them according to the syndrome. Here, below each prescription, the modifications for specific syndromes are detailed, so that during preparation, the therapeutic method is clear. Additionally, ancient texts use the term "Ju" (chewing/crushing), which is explained here as cutting into pieces the size of hemp seeds or beans. "One sheng" (a unit of volume) is equated to one large white cup. Using ancient standards for modern practice makes it easy to understand and universally applicable. For mild conditions, take five qianbi (a small scoop measure) of coarse powder, add one dan (cup) and a half of water, include ginger and jujube, boil until reduced to about seven or eight parts, strain, and drink. Whether to decoct again depends on the situation. For severe conditions, follow the ancient dosage method (ancient 3 liang equals modern 1 liang; 2 liang equals 6.5 qian; ancient 3 sheng equals modern 1 sheng; for larger preparations, use one-third).
Guizhi Tang (Cinnamon Twig Decoction) (1): Taiyang Wind Strike syndrome, characterized by floating-yin weak pulse, fever, sweating, aversion to cold, nasal congestion/mingling, and dry retching, is suitable for this. ○ Taiyang disease with headache, fever, sweating, and aversion to wind is suitable for this. ○ After incorrect purgation in Taiyang disease, if Qi rushes upward, this is suitable. ○ Guizhi is primarily for resolving the muscle layer; if the pulse is floating-tight, with fever and no sweating, do not administer. ○ If Taiyang disease treated with Guizhi Tang results in unresolved irritability, first puncture Fengchi (GB20) and Fengfu (GV16) acupoints, then administer Guizhi Tang. ○ If excessive sweating after Guizhi Tang leads to a flooding-large pulse, give Guizhi Tang; if symptoms resemble malaria occurring twice a day, Guizhi Er Mahuang Yi Tang (Two Parts Cinnamon Twig and One Part Ephedra Decoction) is suitable. ○ If excessive sweating after Guizhi Tang leads to severe irritability and thirst unrelieved, with a flooding-large pulse, Baihu Jia Renshen Tang (White Tiger Plus Ginseng Decoction) governs. ○ If after Guizhi Tang or purgation, head/neck stiffness, low-grade fever, no sweating, epigastric fullness with slight pain, and difficulty urinating persist, Guizhi Qu Gui Jia Fuling Baizhu Tang (Cinnamon Twig Decoction Without Cinnamon Twig Plus Poria and Atractylodes Decoction) governs. ○ In Shanghan with floating pulse, spontaneous sweating, frequent urination, slight irritability, aversion to cold, and leg cramps, if Guizhi Tang causes cold limbs, dry throat, irritability, and vomiting, prepare Gancao Ganjiang Tang (Licorice and Dried Ginger Decoction); once limbs warm, prepare Shaoyao Gancao Tang (Peony and Licorice Decoction) to extend the legs. If stomach Qi is disharmonious, Tiaowei Chengqi Tang (Regulate the Stomach and Order the Qi Decoction) is given. If re-inducing sweating via burning needles occurs, Sini Tang (Counterflow Cold Decoction) governs. ○ If Taiyang exterior syndrome is unresolved with a floating-weak pulse, sweat therapy is indicated. ○ If Taiyang exterior syndrome is unresolved, purgation is contraindicated as it is contrary to treatment; resolving the exterior is suitable. ○ If initial sweating fails and subsequent purgation leaves a floating pulse indicating the pathogen remains outside, resolving the exterior will lead to recovery. ○ Spontaneous sweating indicates harmonious Ying (Nutrient) Qi but disharmony with Wei (Defensive) Qi. Since Ying circulates within the vessels and Wei outside, inducing sweating restores harmony. ○ If internal organs are healthy but periodic fever and sweating persist, it is due to disharmonious Wei Qi; inducing sweating at the right time cures it. ○ In Shanghan with six-seven days of constipation, headache, and fever, if urine is clear, the disease is not in the interior, so induce sweating. ○ If fever and irritability recur half a day after sweating, with a floating-rapid pulse, re-induce sweating. ○ If incorrect purgation causes persistent undigested food in stool and body pain, urgently rescue the Interior with Sini Tang; later, if stool normalizes but body pain persists, urgently rescue the Exterior with Guizhi Tang. ○ Taiyang fever with sweating indicates weak Ying and strong Wei; to rescue from evil wind, this is suitable. ○ After severe purgation and re-sweating, if epigastric fullness and aversion to cold occur, do not attack the fullness; resolve the exterior first with Guizhi Tang, then attack the fullness with Dahuang Huanglian Xiexin Tang (Rhubarb, Coptis, and Scutellaria Heart-Draining Decoction). ○ If Taiyang disease unresolved leads to heat binding in the Bladder, mania-like behavior, and spontaneous bleeding which resolves it, but exterior symptoms remain, resolve the exterior first. Once resolved, if only lower abdominal urgency/pain remains, attack with Taohe Chengqi Tang (Peach Kernel and Cathartic Decoction). (Above belongs to Taiyang chapter) ○ Yangming disease with slow pulse, profuse sweating, slight aversion to cold, and unresolved exterior is suitable for this. ○ If patient has irritability/fever relieved by sweating, resembles malaria, afternoon tidal fever, and solid pulse, Da Chengqi Tang (Major Cathartic Decoction) is suitable; if floating-weak pulse, this [Guizhi Tang] is suitable. (Above belongs to Yangming chapter) ○ Taiyin disease with floating pulse can be treated with sweating. (Belongs to Taiyin chapter) ○ Diarrhea with abdominal fullness and body pain requires warming the Interior first with Sini Tang, then attacking the Exterior. (Belongs to Jueyin chapter) ○ After vomiting/diarrhea cease but body pain persists, Guizhi Tang gently harmonizes. (Belongs to Huoluan chapter)
Ingredients: Guizhi (Cinnamomi Ramulus), Shaoyao (Paeoniae Radix Alba) (3 qian each), Gancao (Glycyrrhizae Radix et Rhizoma) (2 liang, honey-fried).
Cut into hemp seed/bean size. Take 5 qianbi per dose, add 1.5 dan water, 5 slices of fresh ginger, 2 jujubes. Boil to 1 dan, strain, and drink warm. Follow with a bowl of hot thin porridge to assist medicinal power. Cover warmly for about an hour until slight general sweating is achieved.
(Modifications): Guizhi Tang is effective year-round in Northwest China. In Jianghuai region, only winter and spring are suitable. From late spring to pre-Summer Solstice, add 1 fen Huangqin (Scutellariae Radix) for Guizhi syndrome, called Yangdan Tang. Post-Summer Solstice, add 0.5 liang Zhimu (Anemarrhenae Rhizoma) and 1 liang Shigao (Gypsum Fibrosum), or 1 fen Shengma (Cimicifugae Rhizoma). For patients with inherent deficiency-cold, use the original ancient formula without modification.
Warning: Guizhi is difficult to use correctly. Although exterior unresolved with floating pulse suggests sweating, Guizhi Tang is only suitable if the patient has spontaneous sweating, normal urination frequency, warm hands/feet (or slightly cool fingers returning to warmth), and slight irritability with increased cold sensation. Do not use if there is no sweating, frequent urination, cold extremities, no aversion to cold, or if the patient drinks alcohol/dislikes sweet taste. Do not repeat if the Guizhi syndrome disappears after dosing.
Guizhi Mahuang Gemi Tang (Cinnamon Twig and Ephedra Half-Dose Decoction) (2): Taiyang disease lasting 8-9 days, resembling malaria, with fever/aversion to cold, more heat than cold, no vomiting, normal bowel/bladder function, occurring 2-3 times daily, with a slightly slow pulse indicates impending recovery. If pulse is faint with aversion to cold, both Yin and Yang are deficient; do not sweat, purge, or vomit. If face shows redness, resolution is delayed due to inability to produce slight sweat, causing body itching; this is suitable. (Belongs to Taiyang chapter)
Ingredients: Guizhi, Shaoyao, Gancao (fried, 8 qian each), Mahuang (Ephedrae Herba) (0.5 liang, soaked in boiling water, dried, weighed), Xingren (Prunus Armeniacae Semen) (12 kernels, soaked, skin/spout removed, double-kernel type).
Cut into hemp seed/bean size. Take 5 qianbi, 4 slices ginger, 1 jujube, 1.5 dan water. Boil to 0.8 dan, strain, drink warm. (Also seen in Bianwu chapter)
Guizhi Er Mahuang Yi Tang (Two Parts Cinnamon Twig and One Part Ephedra Decoction) (3): After Guizhi Tang causes excessive sweating and flooding-large pulse, give Guizhi Tang as before. If symptoms resemble malaria occurring twice daily, sweating will resolve it; this is suitable. (Belongs to Taiyang chapter)
Ingredients: Guizhi (8.5 qian), Shaoyao (5.5 qian), Xingren (8 kernels, soaked in boiling water, skin/spout removed), Gancao (0.25 liang, fried), Mahuang (3.1 qian, soaked in boiling water to remove yellow juice, dried, weighed).
Cut into hemp seed/bean size. Take 5 qianbi, 4 slices ginger, 1 jujube, 1.5 dan water. Boil to 0.8 dan, drink warm. Aim for slight sweating. (Also seen in Bianwu chapter)
Guizhi Er Yueshi Yi Tang (Two Parts Cinnamon Twig and One Part Yuebi Decoction) (4): Taiyang fever/aversion to cold, more heat than cold, faint pulse indicates "No Yang"; do not sweat. This is suitable. (Belongs to Taiyang chapter)
Ingredients: Guizhi, Shaoyao, Gancao (0.5 liang each), Shigao (Gypsum Fibrosum) (6 qian, crushed), Mahuang (0.5 liang, soaked in boiling water to remove yellow juice, dried, weighed).
Cut into hemp seed/bean size. Take 5 qianbi, 4 slices ginger, 1 jujube, 1.5 dan water. Boil to 0.8 dan, strain, drink warm. (Also seen in Bianwu chapter)
Guizhi Jia Gui Tang (Cinnamon Twig Decoction Plus Cinnamon Twig) (5): Burning needle induces sweating; cold enters needle site, forming red nodules. Bi Pentu (Running Piglet Qi) will arise, rushing from lower abdomen to heart. Moxibustion on each nodule (one moxa cone) plus this medicine. (Belongs to Taiyang chapter)
Ingredients: Guizhi (5 liang), Shaoyao (3 liang), Gancao (2 liang, fried).
Cut into hemp seed/bean size. Take 5 qianbi, 4 slices ginger, 1 jujube, 1.5 dan water. Boil to 0.8 dan, strain, drink warm. (Adding Guizhi to Guizhi Tang helps drain Bi Pentu Qi.)
Guizhi Jia Fuzi Tang (Cinnamon Twig Decoction Plus Aconite Decoction) (6): Taiyang sweating leads to continuous leakage/sweating, aversion to wind, difficulty urinating, slight stiffness/tension in four limbs making flexion/extension difficult. This is suitable. (Belongs to Taiyang chapter)
Ingredients: Guizhi (bark removed), Shaoyao (1.5 liang each), Gancao (1 liang, fried), Fuzi (Aconiti Lateralis Radix Praeparata) (half, roasted, bark/spout removed).
Cut into hemp seed/bean size. Take 5 qianbi, 4 slices ginger, 1 jujube, 1.5 dan water. Boil to 0.8 dan, strain, drink warm.
Guizhi Qu Shaoyao Tang (Cinnamon Twig Decoction Without Peony Decoction) (7): After incorrect purgation in Taiyang, rapid pulse and chest fullness. This is suitable. (Belongs to Taiyang chapter)
