风瘙痒者，是体虚受风，风入腠理，与血气相搏，而俱往来，在于皮肤之间。邪气微，
不能冲击为痛，故但瘙痒也。
风蛊者，由体虚受风，风在皮肤之间。其状，淫淫跃跃，若蛊物刺，一身尽痛，侵伤血
气，动作如蛊毒之状，谓之风蛊。
癞病，是贼风入百脉，伤五脏，连注骨髓俱伤，而发于外，使眉睫堕落，皮肉生疮，筋
烂节断，语声嘶破。而毒风之变，冷热不同，故腠理发癞，形状亦异。
气病，是肺虚所为。肺主气，五脏六腑皆禀气于肺。忧思恐怒，居处饮食不节，伤动肺
气者，并成病。其气之病，有虚有实。其肺气实，谓之有余，则喘逆上气。其肺气虚，谓之
不足，则短乏少气。而有冷有热，热则四肢烦热也，冷则手足逆冷。
心痛，是脏虚受风，风冷邪气乘于心也。其痛发，有死者，有不死成疹者。心为诸脏主
而藏神，其正经不可伤，伤之而痛者，名为真心痛，朝发夕死，夕发朝死。心之支别络，为
风冷所乘而痛者，故痛发乍间乍甚，而成疹也。
心腹痛者，腑脏虚弱，风邪客于其间，与真气相击，故痛。其痛随气上下，或上冲于心
，或下攻于腹，故心腹痛。
Pruritus caused by wind (Feng Sao Yang) arises from a deficiency of the body's constitution leading to susceptibility to wind pathogen. The wind enters the couli (pores and interstices of the skin), contends with the blood and qi, and moves back and forth within the skin. Because the evil factor is slight, it cannot strike forcefully to cause pain; therefore, only itching occurs.
Wind Gu (Feng Gu) also results from a deficient constitution susceptible to wind, with the wind lodging between the skin and muscles. Its manifestation involves a creeping, restless sensation, as if insects or parasites are piercing the body, causing generalized pain throughout the entire body. It invades and damages the blood and qi, and its paroxysmal nature resembles that of gu poison, hence termed Wind Gu.
Leprosy-like disease (Lei Bing) occurs when treacherous wind penetrates the hundred vessels, damaging the five zang organs and extending to the bone marrow. This internal damage manifests externally, causing the loss of eyebrows and eyelashes, sores on the skin and flesh, rotting of tendons, dislocation of joints, and hoarseness or breaking of the voice. Due to variations in the transformation of toxic wind into cold or heat patterns, the resulting skin lesions vary in shape and appearance.
Qi disorders are caused by lung deficiency. The Lung governs qi, and the qi of the five zang and six fu organs all derive from the Lung. Emotional disturbances such as worry, thought, fear, and anger, along with irregular living habits and diet, can injure Lung qi and lead to disease. Qi disorders present as either deficiency or excess. Lung qi excess is termed "repletion," characterized by panting and rebellious qi ascending. Lung qi deficiency is termed "deficiency," characterized by shortness of breath and scanty qi. These may further manifest as cold or heat syndromes: heat presents with vexatious heat in the four limbs, while cold presents with cold extremities.
Heart pain results from heart deficiency allowing wind pathogens to invade, where wind-cold evil factors attack the Heart. Upon onset, some cases prove fatal, while others survive but develop sequelae. The Heart is the master of the five zang organs and houses the Shen (spirit). The primary meridians of the Heart should not be injured; injury to the primary meridians causing pain is called True Heart Pain (Zhen Xin Tong), which is rapidly fatal (death upon onset in the morning leads to death in the evening, and vice versa). If the collateral branches of the Heart are attacked by wind-cold, the pain will fluctuate in intensity, alternating between relief and exacerbation, often leaving behind chronic conditions.
Heart and abdominal pain arise from weakness of the zang and fu organs, allowing wind pathogens to lodge within and contend with the true qi, resulting in pain. This pain migrates with the movement of qi, either rushing upward to affect the Heart or attacking downward into the abdomen, thus presenting as combined heart and abdominal pain.
Abdominal pain is caused by weakness of the zang and fu organs, permitting wind-cold evil factors to invade. When these evil factors contend with the righteous qi, abdominal pain ensues.
Lower abdominal pain originates from pre-existing wind-cold stagnation within the Bao Luo (uterine collaterals/vessels). This pathogen contends with the blood and qi, accumulating in the lower abdomen. Triggered by wind-induced deficiency, it strikes against the blood,
