Wind is the vast qi of heaven and earth; when it is upright and smooth, it can nourish all things, but when it is deviant and evil, it harms all living beings. If a person is struck by evil wind, few escape death. Therefore, if the pathogen enters the zang organs, it is difficult to cure; if the meridians are empty and injured, it results in hemiplegia, paralysis of the limbs, flooding of saliva with dizziness and obstruction, deviation of the mouth and eyes, insensitivity of the skin and flesh, and numbness, atrophy, spasms, and deformities. Depending on the qi of the affected organ, manifestations vary, occurring on either the left or right side. The side where the evil qi resides becomes relaxed and slack, while the side of the healthy qi becomes tense and contracted; the healthy qi pulls toward the diseased side, causing deviation and inability to move freely. Generally, wind is characterized by urgency and violence, moving swiftly and changing rapidly. It strikes people suddenly, causes dizziness, induces floating phlegm, and disrupts the spirit, thus being regarded as the "chief of a hundred diseases." The sages taught this beforehand, and imperial physicians compiled medical texts, hence discussing Wind Stroke (Zhong Feng) first. However, the four climatic factors (Cold, Heat, Summer-heat, Dampness) can all strike humans, presenting symptoms such as flaccidity, spasm, convulsions, numbness, or sudden loss of consciousness. These must be distinguished by pulse diagnosis. Thus it is said: The symptoms of various Bi syndromes caused by Cold and Heat resemble those of Wind; one must rely on pulse differentiation. It is essential to know that a floating pulse indicates Wind, a tight pulse indicates Cold, a fine pulse indicates Dampness, and a rapid pulse indicates Heat. Externally, wandering pain with spontaneous sweating indicates Wind; painful conditions without sweating indicate Cold; flaccidity, weakness, and burning skin indicate Summer-heat; stagnation, swelling, and fullness indicate Dampness. When these factors combine, careful differentiation is required. Only by thoroughly investigating the etiology, combining it with pulse diagnosis, and determining whether the pathology is in the collaterals or meridians, or in the fu or zang organs, can appropriate treatment be applied.

In Liver Wind Strike, the Renying point (ST9) and the left Guan position of the radial artery present a floating and wiry pulse. In Heaven, it corresponds to Wind; in Earth, to Wood; in the human body, to the Liver. Due to Liver deficiency, it is prone to Wind invasion because like attracts like; thus, the pulse manifests at the left Guan. Symptoms of Liver Wind include excessive sweating, aversion to wind, slightly bluish complexion, dizziness and vertigo, unilateral pain in the left hypochondrium, craving for sweet flavors, a sensation resembling pregnancy discomfort, tendon tension with spasms and bi-obstruction preventing extension. Diagnosis involves inspecting the eyes, which appear blue/green.

In Heart Wind Strike, the Renying point (ST9) and the left Cun Kou position of the radial artery present a surging and floating pulse. In Heaven, it corresponds to Heat; in Earth, to Fire; in the human body, to the Heart. Due to Heart deficiency, it is susceptible to evil wind due to the mother-child relationship (Wood generates Fire); thus, the pulse manifests at the left Cun Kou. Symptoms of Heart Wind include excessive sweating, aversion to wind, slightly reddish complexion, slight fever, aphonia (inability to speak), desire for food but vomiting after eating. Diagnosis involves inspecting the tongue, which appears red and scorched/dry.

In Spleen Wind Strike, the Renying point (ST9) and the right Guan position of the radial artery present a floating and slightly slow pulse. In Heaven, it corresponds to Dampness; in Earth, to Earth; in the human body, to the Spleen. Due to Spleen deficiency, it is overcome by Wind (Wood overacts on Earth); thus, the pulse manifests at the right Guan. Symptoms of Spleen Wind include excessive sweating, aversion to wind, pale yellow complexion, lethargy and heaviness of the four limbs, twitching of skin and muscles, fever, shortness of breath, anorexia, somnolence resembling drunkenness. Diagnosis involves inspecting the lips, which appear yellow.

In Lung Wind Strike, the Renying point (ST9) and the right Cun Kou position of the radial artery present a floating, choppy, and short pulse. In Heaven, it corresponds to Dryness; in Earth, to Metal; in the human body, to the Lungs. Due to Lung deficiency, it is attacked by Wind (Fire overacts on Metal); thus, the pulse manifests at the right Cun Kou. Symptoms of Lung Wind include excessive sweating, aversion to wind, bright white complexion, dry mouth, panting, rebellious qi with shoulder breathing, heavy body and back pain, facial edema, improvement during the day and worsening at night. Diagnosis involves inspecting the nose, which appears white.

In Kidney Wind Strike, the Renying point (ST9) and the left Chi position of the radial artery present a floating and slippery pulse. In Heaven, it corresponds to Cold; in Earth, to Water; in the human body, to the Kidneys. Due to Kidney deficiency, it is influenced by Wind due to the mother-child relationship (Metal generates Water); thus, the pulse manifests at the left Chi. Symptoms of Kidney Wind include excessive sweating, aversion to wind, dark/blackish complexion, puffy facial edema, lower back and spine pain radiating to the lower abdomen, difficulty with urination and defecation, increased sweating during sleep, mental confusion and anxiety. Diagnosis involves inspecting the ears, which appear black.

In Stomach Wind Strike, the Renying point (ST9) and both Guan positions of the radial artery present a floating and large pulse. There is no specific treatise on Wind Strike for the six Fu organs, except for the Stomach, because the Stomach is the sea of the five zang organs, receiving the five flavors to nourish them. When deficient, it is struck by evil wind. Symptoms include excessive sweating on the forehead, inability to swallow food and drink, chest and diaphragm obstruction, abdominal fullness, abdominal distension upon exposure to cold, open-mouthed shoulder breathing, palpitations in the epigastrium, and diarrhea after consuming cold foods.
