Shaoyin disease, with a fine, deep, and rapid pulse, indicates the pathology is in the interior; sweating therapy is contraindicated.
A floating and tight pulse typically presents with body pain and should be resolved by sweating. However, if the chi (cun kou) position pulse is slow, sweating is contraindicated. Why is this so? This is due to insufficiency of Ying Qi (Nutritive Qi) and slight deficiency of blood.
In Shaoyin disease, if the pulse is faint (alternatively described as soft and weak), sweating is contraindicated due to Yang Qi deficiency.
A pulse that is soft and weak: the weak quality is found at the guan (middle) position, while the soft quality is found at the cun (superficial/distal) position. The faint quality is found superiorly, and the choppy quality inferiorly. Faintness indicates insufficient Yang Qi; choppy indicates lack of blood. If Yang Qi is faint, wind-stroke with sweating may paradoxically cause restlessness and vexation. Choppy indicates lack of blood, leading to cold limbs and chills. Applying sweating to faint Yang Qi causes restlessness and insomnia.
If there is pulsation (Dong Qi) on the right, sweating is contraindicated. Sweating will cause epistaxis and thirst, severe mental distress, and vomiting immediately after drinking.
If pulsation is on the left, sweating is contraindicated. Sweating will cause dizziness, incessant sweating, and twitching of muscles and sinews.
If pulsation is above, sweating is contraindicated. Sweating will cause Qi to rush upward, striking directly at the heart region.
If pulsation is below, sweating is contraindicated. Sweating will result in anhidrosis, extreme mental distress, severe joint pain, vertigo, aversion to cold, regurgitation of food after eating, and inability of food to pass downward (alternatively stated as indigestion).
If the throat feels obstructed, sweating is contraindicated. Sweating will cause hematemesis, extremely weak or nearly absent respiration, cold limbs, a desire to curl up, and inability to self-warm.
For various pulses that are rapid but weak and faint, sweating is contraindicated. Sweating will cause difficult defecation and dry abdomen (alternatively stated as difficult urination and dry bladder), leading to gastric dryness and vexation. Although these conditions appear similar, their origins differ fundamentally. A pulse that is soft and weak: the weak quality is at the guan position, the soft at the cun position, the wiry quality superiorly, and the faint quality inferiorly. Wiry indicates abnormal Yang movement; faint indicates Yin cold. Upper excess and lower deficiency suggest a need for warming. Faint and wiry indicate deficiency; sweating is contraindicated. Sweating will cause shivering and inability to recover.
Severe coughing with frequent expectoration of saliva, dry throat, difficult urination, and mental hunger/vexation, occurring intermittently like malaria but with chills only and no fever, indicates deficiency-cold chills. Coughing combined with sweating leads to curling up and chest fullness (alternatively stated as heart pain) and abdominal hardness. In cases of Jue (cold limbs), sweating is contraindicated; it will cause voice disorder, hoarseness, tongue flaccidity, and inability of food to pass.
For various adverse conditions, if sweating is applied, mild cases may be difficult to cure, severe cases may present with confused speech, and those with dizzy eyes will die; life cannot be preserved.
In Taiyang disease, after eight or nine days, presenting like malaria with fever and aversion to cold, where heat predominates over cold, without vomiting, and with normal bowel/bladder function, occurring two or three times a day: if the pulse is faint and there is aversion to cold, this indicates dual deficiency of Yin and Yang, and re-sweating is contraindicated.
In Taiyang disease, with fever, aversion to cold, heat predominating over cold, and a faint pulse indicating absence of Yang, re-sweating is contraindicated. Dry throat also contraindicates sweating.
Patients who have lost blood should not undergo surface-attacking sweating; sweating will cause chills and tremors.
Patients prone to epistaxis should not undergo surface-attacking sweating; sweating will cause depression of the forehead, rapid and tense pulse, fixed staring gaze, and insomnia.
Patients prone to sweating, if subjected to heavy sweating, will suffer from mental confusion and anxiety, and pain in the genitalia after urination; Yu Yu Liang Wan (Hematite Pill) may be administered.
Patients with strangury (Lin syndrome) should not sweat; sweating will cause hematuria.
Patients with sores/ulcers, even if experiencing body pain, should not undergo surface-attacking sweating; sweating will lead to Jing (spasm/stiffness).
Sweating during winter will cause vomiting and diarrhea, oral ulcers, and sores.
Diarrhea with undigested food (Qing Gu) contraindicates surface-attacking sweating; sweating will cause abdominal distension. Cough with free urination, or urinary incontinence, contraindicates surface-attacking sweating; sweating will cause cold reversal (Jue Ni). Excessive sweating followed by further sweating will also cause hard stool.
In Shanghan (Cold Damage) from one to two days to four to five days, Jue (cold limbs) must be followed by fever; previous Jue will later become hot. Deeper Jue corresponds to deeper heat; slight Jue corresponds to slight heat. Jue should be treated with purgation; if sweating is mistakenly used, it will cause oral injury and redness. If a patient has a rapid pulse, indicating heat, they should digest food well. If they vomit instead, it is because the physician mistakenly induced sweating, causing faint Yang and deficient Qi in the diaphragm. The rapid pulse here represents "guest Yang" (false heat) which cannot digest food; the stomach is cold and deficient, causing vomiting.
In Shanghan, four to five days in, with a deep pulse, vexation, wheezing, and fullness: a deep pulse indicates interior pathology. Mistaken sweating will cause fluids to leak out, leading to difficult defecation, exterior deficiency and interior excess, and eventually delirium.
Shanghan headache, fever resembling being wrapped in cloth, mimicking wind-stroke, with slight spontaneous sweating and spontaneous vomiting: purgation will worsen mental vexation and discomfort; sweating will cause Jing (spasm), stiff body difficult to flex/extend; moxibustion/fumigation will cause jaundice, urinary retention, and eventually coughing with sputum.
Taiyang disease, after sweating, may lead to Jing (spasm).
Shanghan with wiry-thin pulse, headache, and fever belongs to Shaoyang; Shaoyang disease is contraindicated for sweating.
Combined Taiyang and Shaoyang disease, with stiffness/pain in head and neck, occasional dizziness, intermittent feeling of chest binding, and hardness/fullness below the heart: sweating is contraindicated.
Shaoyin disease with cough and diarrhea, presenting with delirium, results from fire therapy forcing fluids. Urination will be difficult due to forced sweating in Shaoyin.
Shaoyin disease with only Jue (cold limbs) and no sweat: forced sweating will disturb blood, which may exit from any orifice (mouth, nose, eyes); this is called "lower Jue and upper exhaustion," a difficult-to-treat condition.
Shanghan encompasses five types, all belonging to heat diseases. Same disease, different names; same pulse, different meridians. Although all are injured by wind, pre-existing chronic conditions dictate different treatments. If a person previously injured by wind is subsequently injured by heat, wind and heat clash, causing Feng Wen (Wind-Warmth): limbs collapse, headache, body heat, persistent sweating without resolution. Treatment focuses on Shaoyin and Jueyin meridians; sweating is contraindicated. If sweating causes isolated talking, internal vexation, restlessness preventing sleep, fright, and scattered gaze, and the physician sweats again, the physician kills the patient. Wet-Warmth (Shi Wen) in Shanghan: chronic dampness injury leads to middle-jiao stagnation; damp and heat clash, causing Shi Wen. Symptoms include cold reverse legs, abdominal fullness with hands crossing chest, head/eye pain, and delirium. Treatment focuses on Foot-Taiyin; sweating is contraindicated. Sweating causes inability to speak, deafness, unawareness of pain, cyanosis, and color change, named Zhong Ming (deep coma); such patients die, killed by the physician.
