又曰。太阳病。脉浮而数者。可发汗。属桂枝证。(一法用麻黄
汤)雍曰。麻黄桂枝二汤。分恶风恶寒有汗无汗用之。如太阳本证。
庞氏曰。恶寒者不当风而憎寒。恶风者当风而憎寒。皆属表证。
庞氏论桂枝证曰。凡桂枝汤证病有常自汗出。小便不数。手足
温和。或手足指稍露之则微冷。覆之则温。浑身热。微烦而又憎寒。
始可行桂枝汤。若病者身无汗。小便数。或手足厥冷。不恶寒反恶

此外卫不和也。营行脉中。为阴主内。卫行脉外。为阳主外。复发其
汗。卫和则愈。雍曰。二者语小异。而理皆通。脉经尤明。恐本论为后
人笔削。盖营气独和而卫气未和也。故其病外不解。营卫二气本相
和。共循脉内外而行也。今寒不伤营而营气独和。风反伤卫而卫气

Zhang Zhongjing said: The general principle is that in spring and summer, it is appropriate to use the sweating method (Fa Han). Pang Anshi expressed this as "spring is suitable for sweating."
He also said: Whenever using the sweating method, one should ensure that sweat comes out evenly throughout the hands and feet, lasting for about the time it takes to eat a meal; this is better.
One should not let sweat flow profusely like water. If the disease does not resolve, one should induce sweating again. However, excessive sweating will inevitably deplete Yang Qi (Wang Yang). Those with deficient Yang Qi must not be induced to sweat again.
He also said: Whenever taking herbal decoctions to induce sweating, stop administering the medicine once the illness is cured; there is no need to finish the entire dose.
He also said: For conditions where sweating is indicated, if a decoction is unavailable, pills or powders may also be used, provided that sweating occurs and the condition resolves. However, this is not as effective as decoctions tailored to specific patterns.
He also said: In Taiyang disease (disease of the Taiyang channel), if exterior symptoms persist and the pulse is floating and weak, the exterior should be resolved through sweating, preferably using Guizhi Tang (Cinnamon Twig Decoction).
He also said: In Taiyang disease, if the pulse is floating and rapid, sweating may be induced; this belongs to the Guizhi Tang pattern. (Another method uses Mahuang Tang Ephedra Decoction). Guo Yong stated: The distinction between Mahuang Tang and Guizhi Tang lies in differentiating wind aversion vs. cold aversion, and presence vs. absence of sweating. Regarding the primary Taiyang pattern...
Pang Anshi said: Cold aversion (E Han) refers to feeling cold even without exposure to wind; wind aversion (E Feng) refers to feeling cold only when exposed to wind. Both belong to exterior patterns.
Pang Anshi discussed the Guizhi Tang pattern: Patients with this pattern typically exhibit spontaneous sweating, normal urinary frequency, warm hands and feet, or slightly cold fingers when exposed but warming when covered, generalized fever, slight irritability, and aversion to cold. Only then should Guizhi Tang be administered. If the patient has no sweating, frequent urination, cold extremities, aversion to heat rather than cold, or has consumed alcohol, Guizhi Tang must absolutely not be used. This describes spontaneous sweating due to wind-stroke, which fits the Guizhi Tang pattern. He further discussed the Mahuang Tang pattern: In Shanghan (cold damage), a tight and full pulse that feels rough upon pressure indicates the Mahuang Tang pattern. A floating pulse indicates wind, while a tight pulse indicates cold. Wind injures the Wei (Defensive) Qi, and cold injures the Ying (Nutritive) Blood. When both Ying and Wei are affected, there is severe joint pain, and exterior symptoms necessarily include fever, absence of sweating, or wheezing. The patient feels only cold aversion, and the fingertips are slightly cold (Jue), though they warm up after a while, while the palms remain warm. This describes cold damage with no sweating, fitting the Mahuang Tang pattern.
He also said: A tight pulse invariably indicates absence of sweating. If sweating is present despite a tight pulse, it must not be mistaken for the Guizhi Tang pattern.
Zhang Zhongjing said: In Yangming disease, if the pulse is slow, there is abundant sweating, and slight cold aversion, the exterior remains unresolved. Sweating may be induced, fitting the Guizhi Tang pattern.
He also said: If a patient's pulse is floating and large, and upon inquiry, the patient reports only hard stools, this is excess. If diarrhea were present, it would be a adverse sign. Hard stools indicate excess; resolving through sweating leads to recovery. Why? Because a floating pulse indicates the need for sweating to resolve the exterior.
He also said: In Shanghan, if the pulse is neither wiry nor tight but weak, thirst will likely occur. If treated with fire therapy, delirium will ensue. If the pulse is weak, feverish, and floating, resolution comes through sweating. Chang Qizi suggested Chaihu Guizhi Tang. For thirst, Wuling San is indicated. For delirium caused by fire therapy, Longgu Muli Jiuni Tang is indicated.
He also said: If a patient suffers from irritability and heat, which resolve with sweating, or presents with malaria-like symptoms and tidal fever at dusk (Shen hour), this belongs to Yangming disease. If the pulse is floating and deficient, sweating should be induced, fitting the Guizhi Tang pattern.
He also said: If a patient frequently sweats spontaneously, it is because the Ying (Nutritive) Qi is harmonious. Harmonious Ying Qi implies disharmony externally, specifically that the Wei (Defensive) Qi fails to coordinate with the Ying Qi. Ying Qi circulates within the vessels, while Wei Qi circulates outside. Inducing sweating again allows Ying and Wei to harmonize, leading to recovery; this fits the Guizhi Tang pattern. The *Mai Jing* states: Frequent spontaneous sweating indicates harmonious Ying Qi. With harmonious Ying Qi but unresolved exterior symptoms, it is Wei Qi disharmony. Ying Qi is Yin, governing the interior; Wei Qi is Yang, governing the exterior. Inducing sweating again harmonizes Wei Qi, leading to recovery. Guo Yong commented: These two statements differ slightly in wording but share the same logic; the *Mai Jing* is clearer. It is likely the original text was edited by later scholars. Perhaps the Ying Qi alone is harmonized while the Wei Qi is not. Thus, the exterior remains unresolved. Originally, Ying and Wei Qi harmonize and circulate together inside and outside the vessels. Now, cold does not injure the Ying, so Ying Qi remains harmonious alone; wind injures the Wei, causing Wei Qi disharmony. Consequently, Ying and Wei do not communicate or circulate harmoniously together. Therefore, the exterior symptoms persist. One must induce sweating again to expel the pathogenic wind from the Wei Qi, allowing Ying and Wei to harmonize and the disease to resolve. Guizhi is used because it can harmonize Wei Qi but cannot reach the Ying level. Mahuang is not used because it enters both Ying and Wei, repeatedly disturbing the already harmonious Ying Qi, causing both to become deficient and exit as sweat, leading to unceasing leakage and endangering life. This reflects the subtle intent of ancient masters in resolving the exterior. Detailed explanation is provided because people doubt the phrase "Ying Qi is harmonious yet the exterior is unresolved."
He also said: If a patient has no internal organ pathology but experiences periodic fever and spontaneous sweating without resolution, this is due to Wei Qi disharmony. Inducing sweating before the onset of fever leads to recovery; this fits the Guizhi Tang pattern. Guo Yong commented: The previous statement described harmonious Ying Qi failing to extend to Wei Qi; this statement describes disharmonious Wei Qi failing to extend to Ying Qi. Essentially, it is the same pattern. The former refers to constant fever and sweating; the latter refers to fever and sweating occurring at specific times. Hence, the text advises inducing sweating before the onset. The use of Guizhi is identical for both.
He also said: A floating and tight pulse indicates wind and cold respectively. Wind injures Wei Qi, and cold injures Ying Qi. With both Ying and Wei affected and severe joint pain, sweating may be induced using Mahuang Tang. Guo Yong commented: This is a pattern of simultaneous injury to Ying and Wei, hence Guizhi Tang is not used.
He also said: If Taiyang disease persists and heat accumulates in the Bladder, the patient may appear manic. If blood passes spontaneously, the patient recovers. If exterior symptoms remain, internal attack is contraindicated; the exterior must be resolved first using Guizhi Tang. Once the exterior is resolved and blood has not passed, if there is urgency and binding in the lower abdomen, internal attack may proceed using Taohao Chengqi Tang.
He also said: In Taiyang disease with mild wheezing, the exterior is unresolved; Guizhi Jia Houpo Xingzi Tang is indicated.
He also said: In Shanghan with a floating-tight pulse, failure to induce sweating may lead to epistaxis; this fits the Mahuang Tang pattern.
He also said: In Yangming disease with a floating pulse, absence of sweating, and wheezing, inducing sweating leads to recovery; this fits the Mahuang Tang pattern.
He also said: In Taiyang disease with a floating pulse, sweating may be induced; this fits the Guizhi Tang pattern.
He also said: In Taiyang disease with a floating-tight pulse, absence of sweating, fever, and body pain persisting for eight to nine days without resolution, if exterior signs remain, sweating should be induced again. After taking the decoction, symptoms may slightly subside. The patient may feel irritable and wish to close their eyes; severe cases will experience epistaxis, after which the disease resolves. This occurs because Yang Qi is heavily constrained. This fits the Mahuang Tang pattern. Guo Yong commented: "After taking the decoction" refers to taking Mahuang Tang. Patients prone to epistaxis should not be induced to sweat, yet Mahuang Tang is used here because the epistaxis resulted from delayed sweating, so the toxic vapors must be vented.
He also said: A floating pulse indicates an exterior disease; sweating may be induced, fitting the Mahuang Tang pattern. (Some say Guizhi Tang). Guo Yong commented: This also distinguishes between wind-stroke and cold damage, and presence vs. absence of sweating, guiding the choice between Guizhi Tang and Mahuang Tang.
He also said: In Shanghan with constipation for six to seven days, headache, and fever, administer Chengqi Tang. If urine is clear, the disease is not in the interior but remains in the exterior, requiring sweating. If headache is present, epistaxis will likely occur; this fits the Guizhi Tang pattern. Chang Qizi suspected an error, suggesting Mahuang Tang if sweating is needed, or Guizhi Mahuang Ban Tang for mild sweating. Guo Yong commented: One must distinguish between sweating and non-sweating patterns. Clear urine indicates the disease is not in the interior, hence Chengqi Tang is avoided in favor of the other two formulas.
He also said: In cases of diarrhea with abdominal fullness and body pain, first warm the interior, then attack the exterior. Si Ni Tang warms the interior; Guizhi Tang attacks the exterior. Guo Yong commented: Diarrhea is an interior sign; body pain is an exterior sign.
He also said: After diarrhea, if body pain persists but bowel movements and urination are normal, urgently rescue the exterior using Guizhi Tang. Guo Yong commented: This follows the previous case.
He also said: In Taiyang disease with headache, fever, sweating, and wind aversion, this fits the Guizhi Tang pattern.
He also said: In Taiyang wind-stroke, the pulse is floating on the surface and weak on the interior. Floating indicates spontaneous fever; weak indicates spontaneous sweating. With chills, wind aversion, mild fever, nasal congestion, and dry vomiting, this fits the Guizhi Tang pattern.
He also said: In Taiyang disease with fever and sweating, this is due to weak Ying Qi and strong Wei Qi, causing sweating. To rescue against pathogenic wind, Guizhi Tang is indicated. Guo Yong commented: Weak Ying Qi means it is self-harmonious; strong Wei Qi means wind pathogens have invaded. To expel wind, Guizhi must enter the Wei level without disturbing the Ying Qi.
He also said: After purgation in Taiyang disease, if Qi rushes upward, this fits the Guizhi Tang pattern. The *Mai Jing* states: If Qi does not rush upward, do not administer it.
He also said: In Taiyang disease, if initial administration of Guizhi Tang causes increased irritability without resolution, first needle Fengchi and Fengfu points, then administer Guizhi Tang for recovery. Pang Anshi commented: Fengchi is a point on the Foot-Shaoyang Gallbladder channel and a meeting point of the Yang Linking Vessel. We needle Fengchi instead of Tianzhu because the Yang Linking Vessel connects all Yang channels, and the Taiyang channel governs all Yang Qi.
He also said: If moxibustion needles induce sweating, but the puncture sites become cold and develop red nodules, Ben Tun (fleeing pig) disease will occur, with Qi rushing from the lower abdomen to the heart. Apply one moxa cone to each nodule and administer Guizhi Jia Gui Tang.
He also said: In Taiyang disease with stiffness in the neck and back, absence of sweating, and wind aversion, Gegen Tang is the primary treatment.
He also said: In combined Taiyang and Yangming disease with spontaneous diarrhea and no vomiting, this fits the Gegen Tang pattern.
He also said: In combined Taiyang and Yangming disease without diarrhea but with vomiting, Gegen Jia Banxia Tang is indicated.
He also said: In Taiyang disease with a Guizhi pattern, if the physician incorrectly uses purgation, leading to persistent diarrhea and a rapid pulse indicating unresolved exterior, with wheezing and sweating, Gegen Huangqin Huanglian Tang is indicated.
He also said: In Taiyang disease with headache, fever, body and waist pain, joint pain, wind aversion, absence of sweating, and wheezing, this fits the Mahuang Tang pattern. Pang Anshi added: For body/joint pain with floating-rapid or floating-tight pulses, absence of sweating, and normal urination, even after ten days, Mahuang Tang is still appropriate.
He also said: In combined Taiyang and Yangming disease with wheezing and chest fullness, purgation is contraindicated; this fits the Mahuang Tang pattern.
He also said: In Taiyang wind-stroke with a floating-tight pulse, fever, cold aversion, body pain, absence of sweating, and irritability, or headache, Da Qinglong Tang is the primary treatment. If the pulse is weak, with sweating and wind aversion, it is contraindicated. Administration would cause cold limbs and muscle twitching, which is an adverse reaction.
He also said: In Shanghan with a floating-slow pulse, body heaviness without pain (which occasionally lightens), and no Shaoyin signs, Da Qinglong Tang may be used to induce sweating. Guo Yong commented: Da Qinglong Tang is most difficult to identify in these two patterns, leading to frequent misdiagnosis by physicians. The earlier mention of wind-stroke with a floating-tight pulse represents wind-stroke presenting with cold signs. The later mention of cold damage with a floating-slow pulse represents cold damage presenting with wind signs. Pang Anshi noted: It resembles Guizhi Tang pattern but lacks sweating and has a tight pulse; it resembles Mahuang Tang pattern but lacks body pain and has a slow pulse. This is the Da Qinglong Tang pattern. The key lies in recognizing wind-stroke with floating-tight pulse and cold damage with floating-slow pulse. However, Da Qinglong Tang induces sweating much more vigorously than Mahuang Tang. If wind-stroke presents with cold signs and no sweating, it may be used. But if wind-stroke presents with cold signs and spontaneous sweating, Da Qinglong Tang must absolutely not be used. Zhang Zhongjing therefore warned: If the pulse is weak, with sweating and wind aversion, do not administer it. Doing so causes cold limbs and muscle twitching due to extreme Yang depletion from unceasing sweating, which is untreatable. Physicians err because of this. Thus, the Da Qinglong Tang pattern should be subdivided within "wind-stroke with cold signs" into sweating and non-sweating categories, creating three total patterns. The two non-sweating patterns may take Da Qinglong Tang; the one sweating pattern must not. Since there is no formula for the sweating pattern in the original text, Guo Yong suggests using Guizhi Mahuang Ban Tang. Zhang Zhongjing originally used this for fever/chills resembling malaria. Malaria involves both wind and cold, similar to Da Qinglong Tang's origin. Guo Yong speculates that all three Da Qinglong patterns could be treated with modified versions: adding slight amounts of Mahuang for non-sweating cases, and reducing Mahuang for sweating cases. Pang Anshi mentioned Guizhi Shigao Tang could replace Guizhi Tang after the Summer Solstice, and adding half a liang of Mahuang could replace Mahuang Tang or Qinglong Tang, provided there are no Shaoyin signs, as Shaoyin is the most critical channel to avoid sweating.
He also said: In Shanghan with unresolved exterior and fluid retention in the Heart, accompanied by dry heaving, fever, and cough, or thirst, diarrhea, dysphagia, difficulty urinating with lower abdominal fullness, or wheezing, Xiao Qinglong Tang is indicated.
He also said: In Shanghan with fluid retention in the Heart, cough, mild wheezing, fever, and no thirst, if thirst develops after taking the decoction, it indicates the cold is departing and the disease is resolving; this fits the Xiao Qinglong Tang pattern.
He also said: In Yangming wind-stroke with wiry-floating-large pulse, shortness of breath, abdominal fullness, hypochondriac and heart pain, obstruction upon pressure, dry nose with no sweating, lethargy, jaundice of the whole body and eyes, difficulty urinating, tidal fever, occasional hiccups, and swelling around the ears, acupuncture provides slight relief. If exterior symptoms persist beyond ten days and the pulse remains floating, administer Xiao Chaihu Tang. If the pulse is merely floating without other symptoms, administer Mahuang Tang. If there is no urination, abdominal fullness, and hiccups, the condition is untreatable. Guo Yong commented: For jaundice with no urination and hiccups, administer Yinchen Wuling San to promote urination. Without exterior signs and with a non-floating pulse, Shizao Tang may be used to purge.
He also said: In Taiyang disease after ten days, if the pulse is floating-thin and the patient desires sleep, the exterior has resolved. If there is chest fullness and hypochondriac pain, administer Xiao Chaihu Tang. If the pulse is merely floating, administer Mahuang Tang.
He also said: In wind-stroke with alternating chills and fever, or in Shanghan after five to six days, with chest/hypochondriac fullness, silent desire not to eat, irritability, and frequent vomiting, or chest irritability without vomiting, thirst, abdominal pain, hypochondriac hardness, palpitations with difficulty urinating, no thirst with slight fever, or cough, this fits the Xiao Chaihu Tang pattern.
He also said: In Shanghan after four to five days, with body heat, wind aversion, neck stiffness, hypochondriac fullness, warm hands/feet, and thirst, this fits the Xiao Chaihu Tang pattern.
He also said: In Shanghan after six to seven days, with fever, slight cold aversion, limb/joint pain, mild vomiting, and partial constriction in the epigastrium, with unresolved exterior symptoms, Chaihu Guizhi Tang is the primary treatment.
He also said: In Shaoyin disease acquired two to three days prior, Mahuang Fuzi Gancao Tang induces mild sweating because there are no interior signs after two to three days. Guo Yong commented: Shaoyin disease generally prohibits sweating, but this single pattern allows mild sweating.
He also said: With a floating pulse, difficulty urinating, slight fever, and polydipsia, Wuling San is administered to promote urination and induce sweating.
He also said: After purgation in Taiyang disease with a rapid pulse and chest fullness, Guizhi Qu Shaoyao Tang is the primary treatment. Pang Anshi commented: Shaoyao is sour; a rapid pulse and chest fullness risk forming Jie Xiong (chest binding), so Shaoyao is removed to rely entirely on sweet and acrid herbs to disperse toxicity.
He also said: After taking Guizhi Tang or purgatives, if headache, neck stiffness, mild fever, absence of sweating, epigastric fullness with slight pain, and difficulty urinating persist, Guizhi Qu Gui Jia Fuling Baizhu Tang is the primary treatment.
Pang Anshi commented: After three days of Shanghan, if various decoctions fail and the pulse remains unchanged, with Yang Qi still in the meridians and not entering the organs, Guizhi Shigao Tang is indicated. This can replace Guizhi Tang after the Summer Solstice. Adding half a liang of Mahuang allows it to replace Mahuang Tang or Qinglong Tang.
He also said: If Shanghan persists after four to five days of treatment, with toxic heat in the body and red face, Gegen Longdan Tang is the primary treatment. It also treats Yang Du (Yang Toxicity) and Feng Wen (Wind Warmth).
He also said: Dispersing agents primarily use acrid and sweet herbs. Why add bitter herbs? Acrid and sweet reduce Yin Qi and assist Yang Qi. Since heat is abundant in the exterior, bitter herbs are added to disperse it. The *Su Wen* states: "When heat invades internally, disperse it with bitter herbs."
He also said: In epidemic febrile diseases, if after six to seven days there is no sweating, with a洪大 (surging-large) or rapid pulse, red face/eyes, high body heat, irritability, delirium, restlessness, severe thirst, and unresolved heat in the stomach causing locked jaw and inability to speak, this is "Bad Shanghan" (complicated cold damage), untreatable by doctors, resembling death. If the spirit is exhausted but the epigastrium is still warm, pry open the mouth, administer medicine, and the patient may revive. This also treats Yang Du using Maidu Wan (Black Slave Pill in *Huo Ren Shu*).
He also described steaming therapy: If Shanghan patients take sweating decoctions for seven to eight doses without sweating, they die. Steaming them like wind-stroke patients, inviting warm qi from outside, ensures sweating. Ancient methods involve heating earth with firewood, sweeping it clean, sprinkling water, and spreading mulberry leaves, peach leaves, thorn branches, bran, and wheat chaff on the hot ground to a thickness of a hand. The patient lies on a mat covered warmly. In hot months, a quilt suffices. Sweat appears immediately. Once sweat reaches the soles of the feet, apply warm powder to stop sweating. Move the patient to bed for recovery. If mulberry leaves are unavailable, wheat chaff works. Guo Yong commented: This is the Chen Linqiu method recorded in *Qian Jin Fang*, already cited in the introduction; repetition is unnecessary.
He also said: After Shanghan recovery, lingering symptoms ("Bu Liao Liao") may persist for ten days to twenty days, with confusion, loss of spirit, erratic speech, or symptoms resembling ghost possession, tidal fever, flushed cheeks, or malaria-like chills/fever. This results from incomplete sweating leaving residual toxic vapors in the Pericardium collaterals. Zhimu Mahuang Tang is indicated.
He also said: After purgation in Taiyang disease, if Qi rises to the Wei level and the pulse becomes floating, sweating may be induced according to the pattern. Failure to sweat leads to Jie Xiong (chest binding). Generally, if the pulse is floating-large, even with constipation and low urine output, sweating resolves the condition.
He also said: If sweating is indicated but withheld, pore closure leads to suffocation and death.
