(The meridians of all Yang channels circulate around the head. When pathogenic factors contend with the Yang meridians, it results in sweating on the head; therefore, diseases of the Three Yin channels do not present with sweating on the head. The Classics state: If Guan-Ge (obstruction of Qi and fluid metabolism) is unblocked and urination is impossible, yet there is sweating on the head, this is a fatal sign. In patients with dampness, if purgation is incorrectly applied and sweating occurs on the forehead accompanied by difficulty in urination, this is fatal. Similarly, if diarrhea persists incessantly, this is also fatal.)

In Taiyang disease where water accumulates in the chest, there is no significant fever, but only slight sweating on the head. (Da Xianxiong Tang / Great Trap the Chest Decoction may be used). In Yangming disease, sweating occurs on the head, extending only to the neck. With difficulty in urination and thirst, this indicates stagnant heat accumulating within the interior, potentially leading to blood stasis or bleeding manifestations. (Siwu Tang / Four Substances Decoction added with Taoren / Peach Kernel, Honghua / Safflower, Baizhu / Atractylodis Rhizoma, and Gancao / Licorice Root to tonify the Spleen Earth)

(The Stomach governs the four limbs and is the master of body fluids. Sweating on the hands and feet indicates that heat has gathered in the Stomach, causing body fluids to diffuse outward to the periphery. The Classics state: If there is continuous sweating on the hands and feet, it suggests that the stool has hardened, and purgation should be employed. However, in Yangming cold-dampness where the patient cannot eat, has difficulty in urination, and sweats on the hands and feet, this may indicate the impending formation of a stubborn accumulation (Gu Jia), and purgation is contraindicated.)

In Yangming disease presenting with delirium, thirst, abdominal fullness, and constipation/incontinence, there is sweating on the hands and feet. (Da Chengqi Tang / Great Order the Qi Decoction may be used). In Cold-Dampness patterns where the patient cannot eat, food and water are not digested, and there is sweating on the hands and feet, Lizhong Tang / Regulate the Middle Decoction may be used.

(When the Qi of the Zang organs is disharmonious, palpitations may be felt in the skin and muscles. If a patient already has a fixed mass (Pi Ji) and subsequently contracts cold, and the physician, unaware of the condition, erroneously applies sweating or purging methods, it disturbs the organ Qi. This 'moving Qi' manifests according to the area governed by the affected Zang organ, appearing above, below, left, or right of the umbilicus. It does not mention the center of the umbilicus because the Spleen resides in the Central Region (Zhong Zhou) and distributes fluids to the four Zang organs. Since sweating and purging are inadvisable for the left, right, upper, and lower areas, how much more so for the central Spleen? How dare one lightly disturb it?)

Moving Qi located on the Right: Erroneous sweating leads to epistaxis (nosebleed), irritability, thirst, and vomiting water immediately after drinking. (First administer Wuling San / Five-Ingredient Powder with Poria, then Zhuye Tang / Bamboo Leaf Decoction). Erroneous purging leads to fluid deficiency with thirst, dry throat, dry nose, dizziness, and palpitations. (Renshen Baihu Tang / Ginseng White Tiger Decoction added with Chuanxiong / Ligustici Rhizoma). Moving Qi located on the Left: Erroneous sweating leads to dizziness, incessant sweating, twitching of tendons, and muscle fasciculations. (First administer Fangfeng Baizhu Muli Tang / Saposhnikovia, Atractylodes, and Oyster Shell Decoction; once sweating stops, administer Xiaojianzhong Tang / Minor Construct the Middle Decoction). Erroneous purging leads to abdominal cramping, inability to eat, and despite body heat, a desire to curl up and lie down. (First administer Gancao Ganjiang Tang / Licorice and Dried Ginger Decoction, then administer Xiaojianzhong Tang / Minor Construct the Middle Decoction). Moving Qi located Above: Erroneous sweating leads to Qi rushing upward to strike the Heart. (Ligen Tang / Li Tree Root Decoction may be used). Erroneous purging leads to hot palms, irritability, a sensation of floating coldness on the body, spontaneous leakage of cold sweat, and a desire to drink water and pour it over oneself. (Zhuye Tang / Bamboo Leaf Decoction may be used). Moving Qi located Below: Erroneous sweating leads to anhidrosis (no sweat), severe mental restlessness, pain in the bone joints, blurred vision, aversion to cold, and vomiting immediately after eating. (First administer Dajupi Tang / Large Tangerine Peel Decoction; once vomiting stops, administer Xiaojianzhong Tang / Minor Construct the Middle Decoction). Erroneous purging leads to abdominal fullness, dizziness, and passing undigested food in the stool after eating. (Ganxiao Xiexin Tang / Licorice and Pinellia Decoction to Drain the Epigastrium may be used).
