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。
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.
