It is considered that diseases arise urgently, and in a hurried search for pulse and syndrome patterns, the essential principles are difficult to find. Therefore, various applicable and non-applicable prescriptions and treatments have been re-collected; compared with the chapters on Three Yin and Three Yang (Taiyang, Shaoyang, Yangming, Taiyin, Shaoyin, Jueyin), these are easier to consult. Furthermore, sometimes situations extend beyond the scope of Three Yin and Three Yang, appearing in the sections regarding what is applicable or not applicable.

Regarding conditions, symptoms, and formulas for which sweating (Han Fa) or purging (Xia Fa) is contraindicated: if they have already been detailed in the preceding chapters on Three Yin and Three Yang along with their annotations, they are not repeated here; for those not listed previously, they will be fully explained in the subsequent text and annotations. (The Yitong edition reads "subsequently annotated in detail").

A pulse that is soft (Ru) and weak (Ruo), where the Ruo pulse appears at the Guan position, and the Ru pulse appears at the Cun position (Cun refers to the distal end of the pulse); a faint (Wei) pulse appears superficially, and a choppy (Se) pulse appears deeply. A Wei pulse indicates insufficiency of Yang Qi; a Se pulse indicates lack of Blood. With insufficient Yang Qi, wind-strike causes sweating accompanied by restlessness and irritability. Lack of Blood leads to cold limbs and coldness. If sweating is induced in cases of deficient Yang Qi, it results in restlessness and inability to sleep.

The Cun and Guan positions belong to Yang, and the pulse should be floating and vigorous. A Ruo pulse at the Guan position indicates deficiency of interior Qi; a Ru pulse at the Cun position indicates inadequacy of exterior Qi. Wei Qi circulates outside the vessels; a floating pulse at the upper position reflects Wei Qi. A Wei pulse appearing superficially indicates insufficiency of Yang Qi. Ying Qi circulates within the vessels; a deep pulse at the lower position reflects Ying Qi. A Se pulse appearing deeply indicates a lack of Blood. Insufficient Yang Qi fails to secure the exterior, causing the pores to open and relax, allowing Wind pathogen to invade, thus leading to sweating, restlessness, and irritability. Lack of Blood leads to Yin deficiency, preventing the smooth connection between Yin and Yang, resulting in cold limbs and coldness. Deficient Yang Qi and lack of body fluids prevent sweat production; forcing sweating will lead to loss of Yang Qi and restlessness. The Classics state: "Excessive sweating causes loss of Yang Qi, leading to weakness, aversion to wind, irritability, and insomnia."

If there is pulsation (Dong Qi) on the right side, sweating is contraindicated. Inducing sweating will cause epistaxis (Nu) and thirst, bitter心烦 (irritability) in the heart, and vomiting water immediately after drinking.

"Dong Qi" refers to a throbbing sensation in the abdomen. "On the right" refers to the area to the right of the umbilicus. The *Nan Jing* states: "For internal Lung conditions, there is Dong Qi to the right of the umbilicus, which feels firm or painful upon pressure." When Lung Qi is disordered and Zheng Qi (Upright Qi) is internally deficient, Qi moves at the right of the umbilicus. Sweating disturbs Lung Qi. Since the Lung governs Qi and opens into the nose, Qi deficiency fails to control blood, causing blood to overflow and exit through the nose as epistaxis. Loss of body fluids leads to stomach dryness, causing irritability, thirst, and heart discomfort. The Lung dislikes cold; drinking cold liquids injures the Lung, hence vomiting occurs immediately after drinking.

If there is Dong Qi on the left side, sweating is contraindicated. Inducing sweating will cause dizziness, continuous sweating, and twitching of muscles and sinews.

The *Nan Jing* states: "For internal Liver conditions, there is Dong Qi to the left of the umbilicus, which feels firm or painful upon pressure." When Liver Qi is disordered and Zheng Qi is internally deficient, Qi moves at the left of the umbilicus. The Liver is the master of Yin Blood. Inducing sweating leads to continuous perspiration, causing loss of Yang Qi and exterior deficiency, resulting in dizziness and muscle twitching. The *Zhen Jing* states: "Deficiency in the upper jiao causes dizziness."

If there is Dong Qi above the umbilicus, sweating is contraindicated. Inducing sweating will cause Qi to rush upward, striking directly at the epigastrium.

The *Nan Jing* states: "For internal Heart conditions, there is Dong Qi above the umbilicus, which feels firm or painful upon pressure." When Heart Qi is disordered and Zheng Qi is internally deficient, Qi moves above the umbilicus. The Heart belongs to Yang. Sweating causes loss of Yang Qi, further damaging Heart Qi. Kidney Water takes advantage of Heart Qi deficiency to ascend and overwhelm the Heart, causing Qi to rush upward, centered at the epigastrium.

If there is Dong Qi below the umbilicus, sweating is contraindicated. Inducing sweating will result in anhidrosis (lack of sweat), severe mental restlessness, painful bone joints, blurred vision, aversion to cold, vomiting after eating, and food failing to descend.

The *Nan Jing* states: "For internal Kidney conditions, there is Dong Qi below the umbilicus, which feels firm or painful upon pressure." When Kidney Qi is disordered and Zheng Qi is internally deficient, Dong Qi manifests below the umbilicus. The Kidney governs Water. Anhidrosis after sweating indicates insufficient Water. Severe mental restlessness indicates Kidney deficiency failing to control Heart Fire. Painful bone joints occur because the Kidney governs bones. Blurred vision ("KT KT" implying indistinct vision) occurs due to Kidney disease affecting the eyes. Aversion to cold occurs because the Kidney governs cold. Vomiting after eating and food failing to descend indicate depletion of Kidney Water. Wang Bing stated: "Vomiting and regurgitation of old food indicate a lack of Water."

If the throat feels obstructed, sweating is contraindicated. Inducing sweating will cause hematemesis (vomiting blood), impending collapse of Qi, cold hands and feet, a desire to curl up, and inability to self-warm.

The throat is connected to the Stomach. Disharmony of the Stomach Meridian causes obstruction in the throat. Sweating attacks Yang Qi; blood follows the dispersing action and rises, inevitably causing hematemesis. Disharmony of the Stomach Meridian combined with attacking the exterior leads to exterior Yang deficiency, causing impending Qi collapse, cold extremities, and a desire to curl up without being able to warm oneself.

In cases where the pulse is rapid and moving (Shu Dong) yet weak and faint (Wei Ruo), sweating is contraindicated. Inducing sweating will cause difficulty in defecation, abdominal dryness, (Zhao's edition notes: "or difficulty in urination, dryness in the bladder"), stomach dryness, and irritability. Although the manifestations appear similar, the root causes are different.

A Shu Dong pulse indicates Heat in the exterior; a Wei Ruo pulse indicates Heat in the interior. Sweating causes loss of body fluids, intensifying the Heat and drying the Stomach, leading to difficulty in defecation, abdominal dryness, and stomach dryness with irritability. Although the roots differ between exterior and interior, the transmission of Heat after incorrect treatment is the same, hence the similar appearances.

A pulse that is faint (Zhao's edition reads "soft") and weak, with the Ruo pulse at the Guan position and the Ru pulse at the Cun position; a wiry (Xian) pulse appearing superiorly and a Wei pulse appearing inferiorly. A Xian pulse represents Yang movement; a Wei pulse represents Yin Cold. Superior excess and inferior deficiency suggest a need for warming. Faint and wiry pulses indicate deficiency; sweating is contraindicated. Inducing sweating will cause chills and inability to recover.

A Xian pulse superiorly indicates Wind injuring Qi; excessive Wind causes Yang movement. A Wei pulse inferiorly indicates Cold injuring Blood; injured Blood leads to interior Yin Cold. Exterior Qi stagnation constitutes superior excess; interior Yin Cold constitutes inferior deficiency. Exterior Heat and interior Cold suggest a need for warming. Conversely, inducing sweating causes loss of Yang and isolation of Yin, resulting in chills and inability to recover.

In cases of severe cough with frequent expectoration of saliva, dry throat, difficult urination, hunger-like irritability, intermittent malaria-like episodes with chills but no fever, and deficiency-induced chills, inducing sweating during cough will lead to curling up, chest fullness, and abdominal hardness.

Cold Qi in the Lung causing rebellion leads to severe cough. Expectorating saliva causes loss of body fluids and dry throat, leading to difficult urination. Deficiency of Yang Qi in the diaphragm causes hunger-like irritability. Once a day and night, Qi converges in the Lung; when pathogenic and upright Qi clash, malaria-like symptoms occur intermittently, resembling cold malaria but with only chills and no fever, due to deficiency and cold. Sweating attacks Yang Qi, increasing Yang deficiency and Yin Cold severity, resulting in curling up, chest fullness, and abdominal hardness.

In cases of cold limbs (Jue) with a tight (Jin) pulse, sweating is contraindicated. Inducing sweating will cause voice disorder, hoarseness, tongue flaccidity, and inability to speak.

Cold limbs with a tight pulse indicate Shaoyin Cold Damage. The appropriate treatment is to warm the interior; inducing sweating damages Shaoyin Qi. The Shaoyin Meridian enters the Lung, follows the throat, and binds to the base of the tongue. The Kidney is the root, and the Lung is the branch. Root deficiency leads to branch weakness, causing voice disorder, hoarseness, tongue flaccidity, and speech impairment.

For all rebellious conditions, inducing sweating makes mild cases difficult to heal; severe cases presenting with delirious speech and dizziness will die, (Zhao's edition notes: "delirium, dizziness, and chaotic vision will result in death"), and life will be hard to save.

Forcing sweating when contraindicated makes mild cases heavier and harder to heal; severe cases suffer from exhaustion of Yin and Yang Qi, leading to delirium, dizziness, and death. The *Nan Jing* states: "Loss of Yang causes hallucinations (seeing ghosts), which corresponds to delirious speech; loss of Yin causes blindness, which corresponds to dizziness." Dizziness approaching blindness is akin to blindness.

In cases of cough with free urination or urinary incontinence, sweating is contraindicated. Sweating will cause cold reversal in the four limbs.

Lung Meridian deficiency and cold, with upper deficiency failing to regulate the lower, manifest as cough with free urination or incontinence. Sweating in upper deficiency causes external loss of Yang Qi. The four limbs are the root of all Yang Qi; Yang deficiency prevents connection with Yin, causing cold reversal in the limbs.

In Cold Damage with headache, slight fever resembling wind-strike, spontaneous slight sweating, and vomiting, using purgatives increases irritability and causes inner regret (Ao Nao) like hunger. Inducing sweating leads to stiffness (Jing), rigid body, and difficulty in flexion and extension. (Zhao's edition reads "extension and flexion"). Moxibustion or fumigation causes jaundice and urinary retention. Moxibustion induces cough and expectoration of pus.

Cold Damage typically presents with no sweat and aversion to cold. Current symptoms of headache, fever, slight sweating, and vomiting indicate Cold Damage pathogen transforming into Heat and moving inward. Purging allows pathogenic Heat to flow into the chest due to deficiency, causing vexation and inner regret. Sweating makes the exterior deficient; Heat returns to the meridians, generating Wind due to intense Heat, causing rigidity and spasms. Fumigation combines fire and heat, consuming body fluids, leading to urinary difficulty and jaundice. The Lung dislikes fire; moxibustion injures the Lung with fire-heat, inevitably causing cough and expectoration of pus.
