Ji (Palpitation) refers to movement, specifically the palpitation and trembling felt in the epigastrium (heart below). This condition arises after a Shanghan (Cold Damage) disease has been treated with sweating, followed by erroneous purgation. The resulting internal deficiency-heat causes thirst; excessive drinking of water leads to water qi assaulting the heart, inevitably causing aversion to cold, trembling, and epigastric palpitation. In Taiyang disease (Disease of the Taiyang Channel), if urination is difficult due to excessive water intake, palpitation in the epigastrium will certainly occur. If urine output is scant, the patient will suffer from abdominal urgency. A pulse that is floating and rapid indicates that sweating should normally resolve the condition; however, if purgation is erroneously applied, it results in heaviness of the body and palpitation. At this stage, sweating is contraindicated; recovery occurs through spontaneous sweating. This is because a faint pulse at the Chi position (cun-chi method) indicates interior deficiency. Once the exterior and interior are strengthened and body fluids harmonize, spontaneous sweating will occur, leading to cure.

Jing (Spasm) is characterized by fever in the body but cold feet, stiffness in the neck and nape, aversion to cold, occasional heat in the head, heat in the face and eyes, shaking of the head, sudden locking of the jaw, straightening of the back, and opisthotonos (arching of the back). This is caused by heat transferring from the Lung to the Kidney, transforming into Jing. Jing is categorized into Gang Jing (Rigid Spasm) and Rou Jing (Flexible Spasm). In Taiyang disease, fever without sweat accompanied by aversion to cold is Gang Jing; fever with sweat and aversion to cold is Rou Jing. A deep and fine pulse confirms the diagnosis of Jing.

When Taiyang and Shaoyang diseases occur simultaneously (Bing Bing), and the pulse is floating and tight, erroneous purgation causes the tightness to enter the interior, resulting in Pi Syndrome (Glomus). Pi refers to fullness in the epigastrium. For diseases originating in Yin channels, purgation is contraindicated; applying purgation leads to epigastric pi. Upon palpation, the area feels soft without pain, indicating mere Qi stagnation (Qi Pi); further purgation is forbidden. However, if toxic heat assaults the heart, causing epigastric fullness, red face, yellow eyes, delirious speech, and mental confusion, this indicates an Excess pattern. Rapid emesis or purgation is indicated.

Jie Xiong (Chest Binding) refers to the accumulation of toxic heat in the chest and epigastrium. This results from a Yang-channel disease being treated too early with purgation, allowing heat to invade the deficiency and cause binding obstruction. Tenderness upon pressure, with a floating pulse at the Cun position (inch) and a sunken pulse at the Guan position (middle), characterizes Jie Xiong. A large pulse contraindicates purgation; purging such a pulse leads to death. A floating and large pulse also makes purgation inadvisable. If the Yang pulse is floating, while the Guan pulse is small, fine, deep, and tight, yet appetite remains normal and urination is occasionally clear, this is called Zang Jie (Zang Binding). Zang Jie with a white, slippery coating on the tongue is difficult to treat. In cases without alternating chills and fever, where the patient is calm and the tongue lacks a coating, purgation must not be used.
