论曰∶伤寒热病，自古有之。名贤睿哲，多所防御。至于仲景，特有神功，寻思旨趣，
莫测其致。所以医人未能钻仰。尝见太医疗伤寒，惟大青知母等诸冷物投之，极与仲景本意
相反。汤药虽行，百无一效。伤其如此，遂披《伤寒大论》，鸠集要妙。以为其方行之以来，
未有不验。旧法方证，意义幽隐。乃令近智所迷览之者，造次难悟；中庸之士，绝而不思。
故使闾里之中，岁至夭枉之痛，远想令人慨然无已。今以方证同条，比类相附，须有检讨，
仓卒易知。夫寻方之大意，不过三种∶一则桂枝，二则麻黄，三则青龙。此之三方，凡疗伤
寒不出之也。其柴胡等诸方，皆是吐下发汗后不解之事，非是正对之法。术数未深，而天下
名贤，止而不学，诚可悲夫。又有仆隶卑下，冒犯风寒，天行疫疠，先被其毒。悯之酸心，
聊述兹意，为之救法。方虽是旧，弘之惟新。好古君子，嘉其博济之利。物嗤诮焉。

[Discussion]: Cold damage and febrile diseases have existed since ancient times. Sages and wise men of the past had many preventive measures. It was Zhang Zhongjing who demonstrated miraculous medical skills; delving into his purport and interest, one cannot fathom its profundity. Therefore, physicians failed to study it deeply. I once observed that imperial physicians treated cold damage solely with cold-natured substances such as Qingdai (Indigo Naturalis) and Zhimu (Anemarrhenae Rhizoma), which is completely contrary to Zhang Zhongjing's original intent. Although decoctions were administered, there was hardly any efficacy. Grieved by this, I studied the "Treatise on Cold Damage" and collected its essential and subtle prescriptions. Since I began using these formulas in practice, none has failed to be effective. The old methods and formula-patterns had obscure meanings, confusing those of near-intelligence who found them difficult to comprehend in haste; people of average intelligence ceased to think about them. Thus, among the common people, there were yearly sorrows of premature death, which made me sigh endlessly upon reflection. Now, I align formulas with their corresponding patterns and group them by analogy, so that when inspection is needed, they can be easily understood in emergencies. In exploring the general intent of formulas, there are essentially three types: first, Guizhi Tang (Cinnamon Twig Decoction); second, Mahuang Tang (Ephedra Decoction); third, Xiao Qinglong Tang (Minor Blue Dragon Decoction). These three formulas cover all treatments for cold damage. Other formulas such as Chaihu Tang (Bupleurum Decoction) are used for cases where the disease persists after emesis, purgation, or diaphoresis, and are not the primary methods. With shallow medical knowledge, famous scholars of the world stopped learning, which is truly sad. There are also servants and lowly people who offend wind and cold, suffering from epidemic pestilences, being poisoned first. Moved with pity, I briefly state this intention and provide rescue methods. Although the formulas are old, promoting them is new. Gentlemen who love antiquity appreciate the benefit of broad relief, yet they are mocked by others.
Fifty-seven Patterns, Five Formulas
[Discussion]: Cold damage is often confused with dampness diseases and heat diseases, so I narrate and discuss them.
Taiyang disease (Disease of the Taiyang Channel), characterized by fever, absence of sweating, and aversion to cold, is called Gang Ji (Rigid Spasm).
Taiyang disease, characterized by fever, sweating, and no aversion to cold, is called Rou Ji (Soft Spasm). (Another version says aversion to cold.)
Taiyang disease, characterized by fever and a deep, fine pulse, is referred to as Cuo (Spasm).
After Taiyang disease is treated with diaphoresis, it leads to Jing Disease (Spasm).
The patient has body heat, cold feet, stiff neck and back, aversion to cold, occasional head heat and facial redness, red eye vessels, and isolated head tremor; this is Ji Disease (Spasm).
The above describe the manifestations of Ji/Cuo/Jing diseases.
In Taiyang disease with painful and vexatious joint pain and a deep, slow pulse, it is classified as Zhong Shi (Contracting Dampness).
The patient suffers from whole-body pain and vexation, worsening at dusk; this is caused by wind-dampness and sweating.
Patients with chronic dampness suffer from whole-body pain, fever, and a yellowish body color resembling smoked yellow.
Patients with chronic dampness sweat only on the head, have a stiff back, and desire to be covered. If purged prematurely, they may experience hiccups or chest fullness, free urination, and a tongue coating like a placenta. This indicates heat in the Dantian (Lower Abdomen) and cold in the chest, thirst wanting to drink but unable to do so, and dry mouth.
If a dampness patient is purged, leading to sweating on the forehead, slight asthma, and free urination, death ensues. If diarrhea persists without stopping, death also ensues.
Question: In wind-dampness mutual binding causing body pain, diaphoresis should resolve it. However, during rainy weather with continuous rain, the physician suggests diaphoresis, yet the disease does not resolve. Why? Answer: If diaphoresis causes profuse sweating, only the wind pathogen leaves while dampness remains, hence no resolution. To treat wind-dampness, induce slight sweating, appearing as if just about to sweat, so that both wind and dampness are expelled.
The patient has asthma, headache, nasal congestion, and vexation, with a large pulse, normal appetite, and a harmonious abdomen, indicating no internal disease. The pathology is cold-dampness in the head causing nasal congestion. Inserting medicine into the nose will cure it.
The above describe dampness manifestations.
Sun Heat (Zhong Re), also known as Ye (Heat Stroke), involves sweating, aversion to cold, body heat, and thirst.
Sun Heat (Zhong Shu) presents with body heat, heavy pain, and a weak pulse. This results from injuring cold water in summer, with water qi circulating in the skin.
Sun Heat (Zhong Shu) presents with fever, aversion to cold, heaviness, and pain, with a string-taut, fine, knotted, and delayed pulse. After urination, there is coldness in the hands and feet; slight exertion brings heat, and opening the mouth reveals dry teeth. Diaphoresis worsens aversion to cold; moxibustion/warming needles worsen fever; repeated purgation worsens strangury.
The above describe Sun Heat manifestations.
Taiyang disease as a whole presents with stiffness and pain in the head and neck, and aversion to cold.
Taiyang disease presents with a floating pulse.
Taiyang disease, characterized by fever, sweating, aversion to wind, and a slow pulse, is Wind Strike (Zhong Feng).
Taiyang Wind Strike presents with fever and aversion to cold.
In Taiyang disease, if three to four days pass without emesis or purgation, and a knotted pulse appears, diaphoresis should be used.
Diseases with fever and aversion to cold originate in Yang; those without fever and with aversion to cold originate in Yin. Those originating in Yang heal in seven days; those originating in Yin heal in six days, due to the numbers of Yang (seven) and Yin (six).
Headache in Taiyang disease self-resolves after seven days because the channel qi has exhausted. If transmission to another channel is impending, needle the Foot-Yangming channel to prevent transmission and ensure healing.
Taiyang disease tends to resolve between Si hour (9-11 AM) and Wei hour (1-3 PM).
For wind patients whose exterior syndrome has resolved but who feel unwell, recovery occurs in twelve days.
In Taiyang Wind Strike, if the Yang pulse is floating and the Yin pulse is soft and weak, heat arises spontaneously, sweating occurs spontaneously, there is shivering aversion to cold and wind, mild fever, nasal wheezing, and dry vomiting, Guizhi Tang (Cinnamon Twig Decoction) is indicated.
In Taiyang disease with fever and sweating, this indicates Ying (Nutritive) weakness and Wei (Defensive) strength, causing sweating to expel evil wind; Guizhi Tang (Cinnamon Twig Decoction) is indicated.
In Taiyang disease with headache, fever, sweating, and aversion to wind, Guizhi Tang (Cinnamon Twig Decoction) is indicated.
In Taiyang disease with stiffness in the nape and back, accompanied by sweating and aversion to wind, Guizhi Tang (Cinnamon Twig Decoction) is indicated. (The Treatise states: Guizhi Jia Gegen Tang [Cinnamon Twig Decoction with Pueraria]).
If Taiyang disease is treated with purgation and Qi rushes upward, Guizhi Tang (Cinnamon Twig Decoction) may be given; if there is no rushing Qi, it should not be given.
If Taiyang disease persists for three days despite diaphoresis, emesis, purgation, and warming needles, and remains unresolved, it is termed a Ruined Disease (Huai Bing); Guizhi Tang (Cinnamon Twig Decoction) is no longer applicable. Observe the pulse and patterns, identify the deviation, and treat according to the pattern.
Guizhi Tang (Cinnamon Twig Decoction) is originally for releasing the muscle layer; if the pulse is floating and tight with fever and no sweating, it must not be given. Keep this in mind to avoid error.
Wine drinkers (Jiu Ke) should not receive Guizhi Tang (Cinnamon Twig Decoction); doing so causes vomiting because wine drinkers dislike sweet flavors.
For patients with chronic asthma, adding Houpo (Magnolia Bark) and Xingren (Apricot Seed) to Guizhi Tang (Cinnamon Twig Decoction) is beneficial.
Those who vomit after taking Guizhi Tang (Cinnamon Twig Decoction) will likely vomit pus and blood later.
In Taiyang disease, if initial administration of Guizhi Tang (Cinnamon Twig Decoction) causes increased vexation without resolution, first needle Fengchi (GB20) and Fengfu (GV16), then administer Guizhi Tang (Cinnamon Twig Decoction) for cure.
If Taiyang disease exterior patterns remain unresolved and the pulse is floating and weak, diaphoresis is appropriate; Guizhi Tang (Cinnamon Twig Decoction) is indicated.
If Taiyang disease is purged resulting in slight asthma, the exterior remains unresolved; Guizhi Tang (Cinnamon Twig Decoction) is indicated. (Another version says Mahuang Tang [Ephedra Decoction]).
If Taiyang disease has unresolved exterior patterns, purgation is contraindicated as it is a reverse treatment; to resolve the exterior, Guizhi Tang (Cinnamon Twig Decoction) is indicated.
If Taiyang disease fails to resolve after initial diaphoresis and subsequent purgation, but the pulse remains floating, the disease persists. A floating pulse indicates the pathogen is external; purgation was inappropriate. Since the pulse is now floating, the pathogen is still external; resolve the exterior to cure, indicating Guizhi Tang (Cinnamon Twig Decoction).
Patients with spontaneous sweating have harmonious Ying (Nutritive) Qi but disharmonious Wei (Defensive) Qi. Ying circulates within the vessels, Wei outside. Inducing sweating again harmonizes Wei, curing the condition; Guizhi Tang (Cinnamon Twig Decoction) is indicated.
If a patient has no internal organ pathology but experiences periodic fever and spontaneous sweating without resolution, this is Wei (Defensive) Qi disharmony. Induce sweating before the fever onset to cure; Guizhi Tang (Cinnamon Twig Decoction) is indicated.
In cold damage, if there is constipation for six to seven days with headache and fever, Chengqi Tang (Gut-Clearing Decoction) is given. If the stool is unusually green, the pathology is not in the interior but in the exterior; induce diaphoresis. Headache may lead to epistaxis; Guizhi Tang (Cinnamon Twig Decoction) is indicated.
After cold damage is resolved by diaphoresis, if vexation returns half a day later with a floating and rapid pulse, diaphoresis may be repeated; Guizhi Tang (Cinnamon Twig Decoction) is indicated.
If a physician purges cold damage leading to body pain but normal bowel and bladder function, urgently rescue the exterior; Guizhi Tang (Cinnamon Twig Decoction) is indicated.
If Taiyang disease is unresolved and the pulse shows Yin and Yang cessation, chills and shaking precede sweating and resolution. If only the Yang pulse is micro, induce sweating first; Guizhi Tang (Cinnamon Twig Decoction) is indicated.
If Taiyang disease is unresolved with heat binding in the Bladder, the patient acts like a madman, and blood may pass spontaneously, leading to cure. If the exterior remains unresolved, attack is premature; resolve the exterior first with Guizhi Tang (Cinnamon Twig Decoction).
After severe purgation and subsequent diaphoresis in cold damage, if Pi (Glomus/Fullness) forms below the heart with aversion to cold, do not attack the Pi; resolve the exterior first with Guizhi Tang (Cinnamon Twig Decoction).
Formula: Guizhi Tang (Cinnamon Twig Decoction)
Guizhi (Ramulus Cinnamomi), Shaoyao (Radix Paeoniae Rubra), Shengjiang (Rhizoma Zingiberis Recens) [each 2 liang, sliced], Gancao (Radix Glycyrrhizae Uralensis) [2 liang, honey-fried], Dazao (Fructus Jujubae) [12 pieces, torn].
These five ingredients are chopped. Boil three ingredients (Note: Text implies standard preparation) in 7 sheng of water, simmer to obtain 3 sheng, remove dregs. Warm dose 1 sheng. Immediately drink over 1 sheng of hot porridge to assist medicinal power. Cover warmly to induce sweating for about an hour, which is better. If no sweat, repeat dosing. If still no sweat, shorten intervals, administering three doses within half a day. For severe cases, improvement takes one day and night; observe closely. If symptoms persist after one dose, prepare another. Even if no sweat occurs, three doses may resolve it.
If Taiyang disease diaphoresis leads to leakage that does not stop, with aversion to wind, difficulty urinating, slight stiffness in limbs making flexion and extension difficult, Guizhi Jia Fuzi Tang (Cinnamon Twig Decoction with Aconite) is indicated.
Add one Pao Fuzi (Radix Aconiti Lateralis Preparata) to Guizhi Tang (Cinnamon Twig Decoction).
If Taiyang disease is purged leading to a hurried pulse and chest fullness, Guizhi Qu Shaoyao Tang (Cinnamon Twig Decoction Without Peony) is indicated. If there is slight aversion to cold, Guizhi Qu Shaoyao Jia Fuzi Tang (Cinnamon Twig Decoction Without Peony plus Aconite) is indicated. Add one Pao Fuzi (Radix Aconiti Lateralis Preparata) to Guizhi Qu Shaoyao Tang (Cinnamon Twig Decoction Without Peony).
If Taiyang disease persists for eight to nine days, resembling malaria with fever and aversion to cold, more heat than cold, no vomiting, relatively normal bowel/bladder function, occurring two to three times a day: if the pulse is slightly slow and gentle, recovery is imminent; if the pulse is micro with aversion to cold, both Yin and Yang are deficient, and emesis/purgation/diaphoresis are contraindicated. If the face shows redness, resolution is not imminent due to inability to sweat, and the body will likely itch; Guizhi Mahuang Ge Ban Tang (Half-and-Half Cinnamon Twig and Ephedra Decoction) is indicated.
Guizhi (Ramulus Cinnamomi) [1 liang 16 zhu], Shaoyao (Radix Paeoniae Rubra), Shengjiang (Rhizoma Zingiberis Recens) [sliced], Gancao (Radix Glycyrrhizae Uralensis) [fried], Mahuang (Herba Ephedrae) [de-jointed, each 1 liang], Dazao (Fructus Jujubae) [4 pieces, torn], Xingren (Semen Armeniacae Amarum) [24 pieces, skin and pointed ends removed, double-kernel seeds].
Boil these seven ingredients in 5 sheng of water. First boil Mahuang (Herba Ephedrae) for one or two boils, remove foam. Add other herbs, boil to obtain 1.8 sheng, remove dregs. Warm dose 0.6 sheng. Originally: Mix 0.3 sheng of Guizhi Tang (Cinnamon Twig Decoction) and 0.3 sheng of Mahuang Tang (Ephedra Decoction) to make 0.6 sheng, take at once.
If Guizhi Tang (Cinnamon Twig Decoction) causes profuse sweating, and the pulse becomes洪大 (surging and large), giving Guizhi Tang (Cinnamon Twig Decoction) again, if the condition resembles malaria occurring twice a day, sweating resolves it. Guizhi Er Mahuang Yi Tang (Two Parts Cinnamon Twig and One Part Ephedra Decoction) is indicated:
Guizhi (Ramulus Cinnamomi) [1 liang 17 zhu], Mahuang (Herba Ephedrae) [16 zhu], Shengjiang (Rhizoma Zingiberis Recens) [sliced], Shaoyao (Radix Paeoniae Rubra) [each 1 liang 6 zhu], Gancao (Radix Glycyrrhizae Uralensis) [1 liang 2 zhu, fried], Dazao (Fructus Jujubae) [5 pieces, torn], Xingren (Semen Armeniacae Amarum) [16 pieces, skin and pointed ends removed, double-kernel seeds].
Boil these seven ingredients in 7 sheng of water. First boil Mahuang (Herba Ephedrae) for one or two boils, remove foam. Add other herbs, boil to obtain 2 sheng, remove dregs. Warm dose 1 sheng, twice daily. Originally: Mix two parts Guizhi Tang (Cinnamon Twig Decoction) and one part Mahuang Tang (Ephedra Decoction) to make 2 sheng, divide into two doses. Modern practitioners combine them into one formula.
In Taiyang disease with fever and aversion to cold, more heat than cold, and a weak pulse indicating absence of Yang, diaphoresis is contraindicated. Guizhi Er Yuebi Yi Tang (Two Parts Cinnamon Twig and One Part Yuebi Decoction) is indicated:
Guizhi (Ramulus Cinnamomi), Shaoyao (Radix Paeoniae Rubra), Gancao (Radix Glycyrrhizae Uralensis) [fried], Mahuang (Herba Ephedrae) [de-jointed, each 18 zhu], Shengjiang (Rhizoma Zingiberis Recens) [1 liang 3 zhu, sliced], Shigao (Lapis Gypsi Fibrosus) [24 zhu, crushed], Dazao (Fructus Jujubae) [4 pieces, torn].
Boil these seven ingredients in 5 sheng of water. First boil Mahuang (Herba Ephedrae) for one or two boils, remove foam. Add other herbs, boil to obtain 2 sheng, remove dregs. Warm dose 1 sheng. Originally: Reduce to Yuebi Tang (Yuebi Decoction) and Guizhi Tang (Cinnamon Twig Decoction) combined, drink 1 sheng. Now combined into one formula, using two parts Guizhi Tang (Cinnamon Twig Decoction).
If Guizhi Tang (Cinnamon Twig Decoction) is followed by purgation, leading to neck stiffness, mild fever, no sweating, chest fullness, slight pain, and dysuria, Guizhi Qu Guizi Jia Fuling Baizhu Tang (Cinnamon Twig Decoction Without Cinnamon Twig plus Poria and Atractylodes Macrocephala) is indicated:
Fuling (Poria), Baizhu (Rhizoma Atractylodis Macrocephalae) [each 3 liang].
Take Guizhi Tang (Cinnamon Twig Decoction), remove Guizhi (Ramulus Cinnamomi), add these two herbs to make a decoction. Drink 1 sheng; urination will become free. Originally: Guizhi Tang (Cinnamon Twig Decoction) with Guizhi (Ramulus Cinnamomi) removed and Fuling (Poria) and Baizhu (Rhizoma Atractylodis Macrocephalae) added.
