（附脱阳）
人皆以麻木为一病而不知麻与木固自有不同也。所谓麻者。非痒非痛。肌肉之内。如千
万小
虫乱行杂沸。按之不止。搔之愈甚者是也。所谓木者。非痒非痛。自己之肌肉。如他人之肌
肉。按之不知。搔之不觉者是也。麻如木之乱。故名曰麻木。如木之浓。故名曰木。麻犹知
痛痒。而木则全无觉矣。然求其痛之所属将何以断之。盖麻有久暂。木有久暂。临时之麻者
。或因坐卧不得其所四体相压阻节。荣卫血行既迟。而气亦未至故也。然麻或太甚。亦有似
于木焉。临时之木者。亦因坐卧不得其所。四体重压又着寒气一时不曾护持。而荣卫不相联
属。血已不行。而气久不至。故也。然木或还醒。亦有似于麻焉。此其临时之麻木。虽因气
血不足。而有未足为病惟久麻久木者。斯为病耳。
盖经年累月无一日而不麻者。麻之久者也。麻之久者。非坐卧不稳所致。必其内气虚甚。风
痰辏为患。不能作麻。以其挟于风邪。痰为风之所嘘。如
风吹波浪。自腾沸而去。肌肉之中已为风痰所处。阴阳二气失其营运之柄。安得而不麻乎。
经年累月无一日而不木者。木之久者也。亦非坐卧不稳所致。乃是死血凝滞于内。外挟风寒
又因阳气虚败。不能运动而肉已死。若与我不相干。此其所以木也。人之一身。皆气血所养
。气血行迟。即能成病。况其不行乎。此久麻久木所以可畏也。然麻木之处。小犹可治之。
若半体一肢。甚难救疗。医者知此。则人之死生。病之轻重。了然于胸中。而用药之妙。尤在
善处。其可以执法乎。使暂麻暂木而用重剂。则损其真元。久麻久木而用轻剂。则不能取效
。审而治之可也。

人们都以为麻木是一种病，却不知道“麻”与“木”本来就有不同。所谓“麻”，不是痒也不是痛，而是肌肉内部，像有千万只小虫乱跑、杂乱沸腾一样，按压它不能停止，搔抓它反而更厉害，这就是麻。所谓“木”，不是痒也不是痛，而是自己的肌肉，感觉像别人的肌肉一样，按压它不知道，搔抓它没感觉，这就是木。“麻”就像“木”那样混乱，所以叫作麻木；如果像“木”那样浓厚（迟钝），所以叫作木。“麻”还知道痛痒，而“木”则完全没有知觉了。然而要探究这种痛觉缺失属于什么性质，该如何判断呢？大概“麻”有暂时和长久的区别，“木”也有暂时和长久的区别。暂时的“麻”，可能是因为坐卧姿势不当，四肢相互压迫阻碍了关节，导致营卫之气和血液运行迟缓，而气也没有到达的缘故。但是“麻”如果太严重，也有类似“木”的情况。暂时的“木”，也是因为坐卧姿势不当，四肢受到重压，又遭受寒气侵袭，一时没有保护好，导致营卫之气不相连接，血液已经不行，而气长时间不到达的缘故。但是“木”如果恢复知觉，也有类似“麻”的情况。这些暂时的麻木，虽然是因为气血不足引起的，但不足以成为疾病，只有长久的“麻”和长久的“木”，这才是病。
常年累月没有一天不感到“麻”的，就是长久的“麻”。长久的“麻”，不是由坐卧不稳引起的，一定是体内正气非常虚弱，风邪和痰浊聚集为患。之所以不能表现为普通的“麻”，是因为它夹杂了风邪，痰被风所吹动，就像风吹波浪，自己翻腾涌起而去。肌肉之中已经被风痰占据，阴阳二气失去了运行的主导权，怎么能不感到“麻”呢？常年累月没有一天不感到“木”的，就是长久的“木”。这也不是由坐卧不稳引起的，而是死血（瘀血）在体内凝滞，外部又挟带风寒，再加上阳气虚败，不能运动，导致肌肉已经坏死，好像与自己无关一样，这就是“木”的原因。人的全身，都是由气血来滋养的，气血运行迟缓，就能形成疾病，何况是不运行呢？这就是长久的“麻”和长久的“木”令人畏惧的原因。然而，麻木的部位如果只是局部的，还可以治疗；如果是半身或整个肢体，就很难救治了。医生知道了这一点，那么人的生死、病的轻重，心中就了然于胸，而用药的精妙之处，尤其在于善于处理病情。怎么可以拘泥于固定的法则呢？如果让暂时的“麻”和“木”使用重剂，就会损伤人体的真元；长久的“麻”和“木”使用轻剂，就不能取得疗效。审察清楚后进行治疗就可以了。
(Attached: Syndrome of Yang Collapse)
People generally consider numbness (Mumu, a sensation of loss of feeling and tingling) as a single disease, unaware that "Ma" (tingling/numbness with residual sensation) and "Mu" (complete anesthesia/wood-like insensitivity) are inherently distinct. What is termed "Ma" is neither itching nor pain; rather, within the muscles, it feels as if thousands of tiny insects are running chaotically and boiling restlessly. Pressing upon it does not alleviate it, and scratching it exacerbates it. This is what is meant by "Ma." What is termed "Mu" is also neither itching nor pain; the muscles feel as though they belong to someone else. One cannot perceive pressure when pressing, nor sensation when scratching. This is what is meant by "Mu." "Ma" resembles the chaos of "Mu," hence the term "Mumu"; if the insensitivity is profound like "Mu," it is called "Mu." In "Ma," one still perceives pain and itch, whereas in "Mu," all sensation is completely absent. However, to determine the nature of this loss of sensation, how should one differentiate it? Generally, there are transient and chronic forms of both "Ma" and "Mu." Transient "Ma" may occur due to improper sitting or lying postures where limbs compress each other, obstructing joints. This causes the circulation of Ying-Wei Qi (Defensive and Nutritive Qi) and blood to slow down, and Qi fails to reach the area. However, if "Ma" is severe, it may resemble "Mu." Transient "Mu" also results from improper postures, heavy compression of limbs, exposure to cold pathogenic factors without adequate protection, leading to a disconnection between Ying-Wei Qi. Blood flow ceases, and Qi fails to arrive for an extended period. Conversely, if "Mu" recovers sensation, it may resemble "Ma." These transient forms of numbness, although caused by insufficient Qi and Blood, are not diseases in themselves; only chronic "Ma" and chronic "Mu" constitute pathological conditions.
Chronic "Ma," persisting year after month without a single day free from it, is long-standing. Chronic "Ma" is not caused by unstable postures but by severe deficiency of internal Qi, where Wind and Phlegm accumulate to cause pathology. It manifests differently because it is compounded by Wind Pathogen; Phlegm is stirred by Wind, akin to wind blowing waves that churn and rise. The muscles are occupied by Wind-Phlegm, causing Yin and Yang Qi to lose their regulatory control, inevitably resulting in "Ma." Chronic "Mu," persisting year after month without relief, is long-standing. It is not caused by unstable postures but by stagnant dead blood (Blood Stasis) internally, externally compounded by Wind-Cold, and further exacerbated by failure of Yang Qi due to deficiency and collapse. Unable to move, the muscles become necrotic, feeling as if disconnected from the self; this is the essence of "Mu." The entire body is nourished by Qi and Blood. If Qi and Blood circulation slows, disease arises; how much more so if circulation stops entirely? This is why chronic "Ma" and "Mu" are feared. Nevertheless, localized numbness is treatable, whereas hemibody or limb-wide numbness is difficult to cure. A physician who understands this will clearly grasp the prognosis of life and death and the severity of illness in mind. The subtlety of prescription lies particularly in appropriate management. One must not rigidly adhere to fixed rules. Using heavy tonics or purgatives for transient numbness damages True Yuan (Original Qi); using light agents for chronic numbness yields no effect. Treatment must be based on careful examination and differentiation.
