风邪这一病邪，在大人身上表现为中风，在小儿身上则表现为惊风。大人不易受惊，所以称为“中”；小儿容易受惊，且容易引发此病，症状都具备。表证慢惊与中脏（邪气侵入内脏）的症状相同，被称为阴症，其症状都在体内显现。治疗者如果能辨别其阴阳表里而进行治疗，就可以避免失误。
所谓燥热不宁的，是急惊风的症状。慢惊风的症状是：身体经常不发热，眼睛经常半睁，手足轻微抽搐，精神疲倦懈怠，形体看起来呆滞，大便有时泄泻。又有慢脾风，虎口纹呈青紫色或黑色，隐隐混杂，似有似无，手足不动，全身发冷，两眼经常闭合，不能啼哭，症状发展到这种地步，就无法救治了。慢惊病的病根虽然有浅深之分，但在万分之一的情況下还可以施治。如果是因急惊转变为慢惊，或因吐泻产生慢惊，那就难治了。如果因慢惊发展成慢脾风，或因吐泻导致慢脾风，那就无法治愈了。
大体上，惊归属于心，风归属于肝。心火动则身体振颤跳动而不可遏制，肝气发作故抽搐掣动而不能自控。这两经相互助长，其势必然强盛。心火有余，则火势炽盛而风更加猛烈，这是风从火出；肝有余则风狂而火更加旺盛，这是火从风炽。风火同时发作，所以令人畏惧。这特指急惊而言。而慢惊和慢脾风，又兼有脾虚与寒，势头虽然稍缓但病位更深。然而因为病情可生可死，细分起来，各自有所归属，并不是说只局限于心肝二经，而不进入其他经络。
因此，不时吊眼（眼球向上翻），是惊入于肝；梦中磨牙，是惊入于肾；夜间啼哭直到晚上，是惊入于小肠；喉中声音如锯，是惊入于大肠；面色青、下唇白，是惊入于胆；气喘、吸水（吸吮动作），是惊入于脾；不时干呕，是惊入于胃；睡中惊哭，患病在三焦。这些都是可以生存的病症。至于指甲发黑是肝绝，泻黑血是心绝，长期盗汗是胃绝，突然失声是肺绝，咬人是骨绝，眼睛半开半合是肾绝，口鼻干燥发黑是脾绝。惊风出现这七种绝症，这孩子怎么能存活呢？
Wind pathogen, when manifesting in adults, is termed Stroke (Zhong Feng); in children, it is termed Convulsion (Jing Feng). Adults are less prone to fright, hence the term "Stroke" (penetration); children are easily frightened and susceptible to this condition, presenting with all associated symptoms. The exterior-type slow convulsion shares symptoms with Zang-organ penetration (Zang Zang), classified as Yin Syndrome, where symptoms reside internally. If practitioners can distinguish between Yin/Yang and Exterior/Interior to treat accordingly, errors may be avoided.
The state of restlessness due to dryness and heat characterizes acute convulsion. Slow convulsion is characterized by: body temperature often not elevated, eyes often half-open, slight twitching of hands and feet, mental fatigue and lassitude, a dull physical appearance, and occasional diarrhea. There is also Slow Spleen Wind, marked by blue-purple or blackish lines on the Tiger's Mouth (Hukou) area, faintly mixed, appearing yet not fully emerging; immobility of hands and feet; coldness throughout the body; eyes often closed; inability to cry. When symptoms reach this stage, recovery is impossible. Although the root of slow convulsion varies in depth, treatment may still be attempted in rare cases. However, if slow convulsion arises from the transformation of acute convulsion, or from vomiting and diarrhea, it becomes difficult to treat. If slow spleen wind develops from slow convulsion, or results from vomiting and diarrhea, it is incurable.
Generally, Fright belongs to the Heart, and Wind belongs to the Liver. When Heart Fire agitates, tremors and jumping occur uncontrollably; when Liver Qi erupts, spasms and clonic movements happen without self-control. These two meridians assist each other, making the pathological force vigorous. Excess Heart Fire leads to blazing fire and intensified wind, meaning wind emerges from fire; excess Liver leads to wild wind and flourishing fire, meaning fire blazes from wind. With wind and fire erupting together, the condition is formidable. This description specifically applies to acute convulsion. In contrast, slow convulsion and slow spleen wind involve both Spleen deficiency and Cold; although the progression seems slower, the pathology penetrates deeper. Since the disease course can lead to life or death, detailed differentiation reveals specific organ involvement, indicating that the pathology is not confined solely to the Heart and Liver meridians but extends to others.
Therefore, frequent upward deviation of the eyes indicates Fright entering the Liver; grinding teeth in dreams indicates Fright entering the Kidney; night crying persisting until late evening indicates Fright entering the Small Intestine; a sawing sound in the throat indicates Fright entering the Large Intestine; a green face with white lower lip indicates Fright entering the Gallbladder; panting and sucking motions indicate Fright entering the Spleen; frequent dry retching indicates Fright entering the Stomach; startled crying during sleep indicates pathology in the Sanjiao (Triple Burner). These are all survivable conditions. Conversely, black fingernails indicate Liver Extinction; passage of black blood indicates Heart Extinction; chronic nocturnal sweating indicates Stomach Extinction; sudden loss of voice indicates Lung Extinction; biting indicates Bone Extinction; eyes half-open and half-closed indicate Kidney Extinction; dry and black mouth and nose indicate Spleen Extinction. If convulsion presents with these Seven Extinctions, how can the child survive?
