血痹者，由体虚，邪入于阴经故也，血为阴，邪入于血而痹，故为血痹也。其状，形体
如被微风所吹。此由忧乐之人，骨弱肌肤盛，因疲劳汗出，卧不时动摇，肤腠开，为风邪所
侵也。诊其脉自微涩，在寸口、关上小紧，血痹也。宜可针引阳气，令脉和紧去则愈。
风惊邪者，由体虚，风邪伤于心之经也。心为手少阴之经，心气虚，则风邪乘虚伤其经
，入舍于心，故为风惊邪也。其状，乍惊乍喜，恍惚失常是也。
风惊悸者，由体虚，心气不足，心之腑为风邪所乘；或恐惧忧迫，令心气虚，亦受于风
邪。风邪搏于心，则惊不自安。惊不已，则悸动不定。其状，目精不转，而不能呼。
诊其脉，动而弱者，惊悸也。动则为惊，弱则为悸。
风惊恐者，由体虚受风，入乘脏腑。其状，如人将捕之。心虚则惊，肝虚则恐。足厥阴
为肝之经，与胆合；足少阳为胆之经，主决断众事。心肝虚而受风邪，胆气又弱，而为风所
乘，恐如人捕之。
风惊者，由体虚，心气不足，为风邪所乘也。心藏神而主血脉，心气不足则虚，虚则血
乱，血乱则气并于血，气血相并，又被风邪所乘，故惊不安定，名为风惊。
诊其脉至如数，使人暴惊，三四日自已。
《养生方》云∶精藏于玉房，交接太数，则失精。失精者，令人怅怅，心常惊悸。
血痹，是由于身体虚弱，邪气侵入阴经所致。血属于阴，邪气侵入血脉导致气血运行不畅而形成痹阻，所以称为血痹。其症状表现，感觉身体像被微风吹拂一样不适。这多由情绪波动大（忧愁或喜乐过度）的人，骨骼柔弱但肌肤丰盈，因疲劳出汗后，睡眠时身体不时翻动，导致皮肤腠理开泄，风邪趁机侵袭所致。诊察其脉象，脉来微弱而涩，在寸口和关部略显紧象，这是血痹的表现。适宜采用针刺方法引导阳气，使脉象调和、紧象消失即可痊愈。
风惊邪，是由于身体虚弱，风邪损伤心之经脉所致。心属于手少阴经，若心气虚弱，风邪便乘虚侵入该经脉，内舍于心，所以称为风惊邪。其症状表现，时而惊恐，时而喜悦，神志恍惚，行为失常。
风惊悸，是由于身体虚弱，心气不足，心的腑脏为风邪所乘；或因恐惧、忧愁逼迫，导致心气虚弱，也易受风邪侵袭。风邪与心气搏结，则使人惊恐不安。惊恐不止，则出现心悸动摇不定。其症状表现，眼球呆滞不转动，不能呼喊。诊察其脉象，脉动而弱，是惊悸的表现。脉动主惊，脉弱主悸。
风惊恐，是由于身体虚弱感受风邪，风邪侵入并乘袭脏腑所致。其症状表现，感觉像有人要抓捕自己一样。心气虚则易惊，肝气虚则易恐。足厥阴经是肝的经脉，与胆相表里；足少阳经是胆的经脉，主管决断各种事务。心肝两虚而受风邪侵袭，胆气又虚弱，被风邪所乘，因此产生如同被人追捕般的恐惧感。
风惊，是由于身体虚弱，心气不足，被风邪所乘所致。心藏神且主宰血脉，心气不足则心虚，心虚则血液运行紊乱，血液紊乱则气机并聚于血中，气血相互搏结，再加上被风邪侵袭，所以惊恐不安定，名为风惊。诊察其脉象，脉来急促如数脉，使人突然受到惊吓，经过三四天可自行恢复。《养生方》说：精液藏于生殖器（玉房），如果房事过于频繁，就会耗损精液。耗损精液的人，会感到心神不宁，心中常常惊恐悸动。
Blood Bi (Blood Obstruction) is caused by physical deficiency, allowing pathogenic factors to enter the Yin meridians. Blood belongs to Yin; when pathogenic factors invade the blood vessels causing obstruction of Qi and blood flow, it is termed Blood Bi. Its manifestation is a sensation as if the body were being blown by a gentle breeze. This condition often occurs in individuals with emotional instability (excessive sorrow or joy), who have weak bones but abundant flesh. Due to fatigue and sweating, followed by restless sleep that causes frequent turning, the skin pores (Couli) open, allowing Wind pathogenic factors to invade. Upon pulse diagnosis, the pulse is faint and choppy, with a slight tightness at the Cunkou (radial artery at the wrist crease) and Guan positions, indicating Blood Bi. Treatment should involve acupuncture to guide Yang Qi, harmonizing the pulse and eliminating the tightness for recovery.
Wind Jingxie (Wind-induced Fright Syndrome) is caused by physical deficiency, where Wind pathogenic factors damage the Heart meridian. The Heart corresponds to the Hand-Shaoyin meridian. When Heart Qi is deficient, Wind pathogenic factors take advantage of the deficiency to invade the meridian and lodge in the Heart, resulting in Wind Jingxie. Its manifestations include alternating episodes of fright and joy, mental confusion, and abnormal behavior.
Wind Jingji (Wind-induced Palpitation and Fright) is caused by physical deficiency and insufficient Heart Qi, allowing Wind pathogenic factors to invade the Heart's associated fu organs. Alternatively, fear or distress may deplete Heart Qi, making one susceptible to Wind invasion. When Wind pathogenic factors contend with the Heart, fright and unease arise. If fright persists, palpitations and restlessness ensue. Manifestations include fixed gaze without eye movement and an inability to shout. Pulse diagnosis reveals a moving and weak pulse, indicative of Jingji. A moving pulse indicates Fright, while a weak pulse indicates Palpitation.
Wind Jingkong (Wind-induced Fright and Terror) results from physical deficiency and Wind invasion affecting the Zang-fu organs. The symptom is a feeling as if someone is about to capture them. Deficiency of the Heart leads to Fright, while deficiency of the Liver leads to Terror. The Foot-Jueyin meridian is the Liver meridian, interiorly-exteriorly related to the Gallbladder; the Foot-Shaoyang meridian is the Gallbladder meridian, governing decision-making. When Heart and Liver are deficient and invaded by Wind, and Gallbladder Qi is also weak, the person experiences terror akin to being hunted.
Wind Jing (Wind-induced Fright) is caused by physical deficiency and insufficient Heart Qi, which is then invaded by Wind pathogenic factors. The Heart stores the Shen (Spirit) and governs the blood vessels. Insufficient Heart Qi leads to emptiness, causing chaotic blood flow. Chaotic blood flow causes Qi to congregate with the blood; when Qi and Blood contend and are further invaded by Wind, the result is unstable fright, named Wind Jing. Pulse diagnosis shows a rapid-like pulse. If this causes sudden fright, it will resolve spontaneously after three to four days. The *Yangsheng Fang* states: Essence is stored in the genitalia. Excessive sexual intercourse leads to essence loss. Those who lose essence feel despondent and suffer from constant fright and palpitations.
