营气与卫气运行滞涩、不能畅行，就会导致麻木。例如久坐时身体倚靠在某处，压迫住局部部位，导致该处发麻且无法抬起，其中的道理由此可见。发麻多归属于痰湿或气虚；发木则完全归属于湿痰和瘀血（死血），表现为某一块区域不知痛痒，如同木头一般。若脉象沉滑，且患者体型肥胖，多属痰湿所致，可用二术汤（苍术、白术）合二陈汤，先少量佐以羌活、独活、桂枝等风药一至两味，随后兼用人参、黄芪补气。若脉象微弱，或弦大但按之无力，且病程长久、身体消瘦者，属于气虚，可用补中益气汤加一片熟附子；夏季可配合生脉散，或使用清燥汤。若某一块区域不知痛痒，阴寒之气更甚，或者白天轻晚上重，脉象涩而芤（中空如葱管）或弦，属于痰湿夹杂瘀血，宜采用活血行气之法，用二陈汤加川芎、当归、桃仁泥、红花、牛膝、韭汁等药物。若大便呈黑色但不腹泻，可用小剂量的桃核承气汤轻微通下。十个手指麻木，属于胃中有湿痰和瘀血，用二陈汤加苍术、白术、桃仁、红花，并少量加入附子以通行经络。湿热下注导致双脚麻木，或者感觉如火烧燎一样，可用二妙散加牛膝制成丸剂；若无效，可少量加入肉桂。李东垣曾治疗一位闭眼时浑身麻木、睁眼时症状逐渐减轻直至停止的患者，其特点是白天减轻、夜间加重，这是阳气衰弱而湿邪潜伏在阴分所致，用三痹汤去掉乌头，加入苍术、黄柏。又有另一位患者，闭眼则麻木，睁眼即不麻木，靠近火源则头晕目眩，这是风气下陷于血分，不得升发越出所致，也用三痹汤去掉乌头，加入羌活、麻黄。凡是平素有抑郁情绪的妇女，应当疏解郁结，用逍遥散加入补气、行湿的药物。
薛立斋治疗刘孟春，此人素有痰疾，双臂发麻，双眼流泪。服用祛风化痰药后，痰症反而加重，手臂疼痛且不能伸展，手指全部拘挛。薛立斋说：麻木属于气虚，因为之前的药物再次损伤了肝脏，导致火盛而引起筋脉拘挛。况且风自火出，应当补益脾肺、滋补肾水，则风邪自然消退，痰浊自然清除。于是使用六味丸、补中益气汤，三个月后痊愈。
石顽治疗洋商巴慈明的妻子，产后出现眩晕、心悸，神魂离散，好像失去了脏腑支撑的状态。睁眼时遍体麻木，感觉如在云雾之中，必须紧闭双目，才觉得稍微舒适。白天烦躁不安，夜晚则安静。专门从事妇科的医生，使用四物汤等补血药物，患者却呕吐逆气、不能进食；换一位医生使用干姜、附子等热性药物，患者则躁动不安、难以宁静。其脉象虚大而数，重按则散乱无根，轻取应指。这是心火浮散的表现。因难产受惊，痰饮乘虚侵入心包络，留伏在膈上，有入无出，所以病情绵延不断。大概是因为眼睛睁开则全身孔窍皆开，痰火堵塞心窍，所以神识失去主宰；眼睛闭合则诸窍俱闭，痰火潜伏而不运行，所以得以稍安。这与李东垣所说的“闭眼则阳气不行”导致的麻木截然不同。况且此病白天重晚上轻，明显是上焦阳位发生的疾病。给予理痰清火的药剂，各种症状逐渐平息。然而有时因惊吓愤怒，或因饮食不当，不时发作，这是因为伏匿在膈上的痰浊，无法彻底搜刮涤除。趁发作之时，用独参汤送服紫雪丹开通膈膜，然后继续服用前药，调理滋补半年后康复。
When Ying Qi (Nutritive Qi) and Wei Qi (Defensive Qi) stagnate and fail to circulate, numbness and anesthesia occur. For instance, when sitting for a long time and leaning against something, compressing a specific area, one feels numbness in that spot and cannot lift it; the rationale is evident here. Numbness (Ma) generally belongs to Phlegm or Deficiency, whereas woodiness/anesthesia (Mu) entirely belongs to Damp-Phlegm and Dead Blood (stasis). It manifests as a localized area unaware of pain or itchiness, resembling a piece of wood. If the pulse is deep and slippery, and the patient has a robust physique, it indicates Phlegm and Dampness. Use Er Zhu Tang (Cangzhu and Baizhu Decoction) combined with Er Chen Tang, initially adding one or two wind-dispelling herbs such as Qiang Huo (Notopterygii Rhizoma), Du Huo (Angelicae Pubescentis Radix), or Gui Zhi (Cinnamomi Ramulus) in small doses, followed by supplementation with Ren Shen (Ginseng Radix) and Huang Qi (Astragali Radix) to tonify Qi. If the pulse is weak or string-taut and large but powerless upon pressure, and the disease has been prolonged with a emaciated body, it belongs to Qi Deficiency. Use Bu Zhong Yi Qi Tang (Tonify the Middle and Augment the Qi Decoction) with one slice of Shu Fu Zi (Prepared Aconiti Lateralis Radix); in summer, combine with Sheng Mai San (Generate the Pulse Powder) or Qing Zao Tang (Clear Dryness Decoction). If a specific block is unaware of pain and itchiness, with Yin-Cold being severe, or symptoms lighter during the day and heavier at night, and the pulse is choppy and Kou (cork-like/hollow) or string-taut, it indicates Phlegm complicated by Dead Blood. One should promote blood circulation and move Qi using Er Chen Tang added with Xiong Chuann (Chuanxiong Rhizome), Dang Gui (Angelicae Sinensis Radix), Tao Ren (Persicae Semen), Hong Hua (Carthami Flos), Niu Xi (Achyranthis Bidentatae Radix), and Jiu Zhi (Allii Tuberosi Juice). If black stools appear without diarrhea, use a small dose of Tao He Cheng Qi Tang (Peach Pit Decoctioin to Order the Qi) to mildly induce purgation. Numbness in all ten fingers belongs to Damp-Phlegm and Dead Blood in the Stomach. Use Er Chen Tang added with Er Zhu (Cangzhu and Baizhu), Tao Ren, and Hong Hua, with a small amount of Fu Zi (Aconiti Radix) to unblock the collaterals. Numbness in both legs due to Damp-Heat flowing downward, or feeling like burning, can be treated with Er Miao San (Two Marvels Powder) added with Niu Xi, made into pills. If ineffective, add a small amount of Rou Gui (Cinnamomi Cortex). Li Dongyuan treated a patient whose whole body became numb when closing eyes and gradually subsided upon opening them, stopping only after a while. Symptoms were lighter during the day and heavier at night, indicating Yang Qi deficiency with Dampness lurking in the Yin aspect. The prescription was San Bi Tang (Three Obstructions Decoction) with Wu Tou (Aconiti Radix) removed, added with Cang Zhu (Atractylodis Rhizoma) and Huang Bai (Phellodendri Cortex). In another case where numbness occurred upon closing eyes and ceased upon opening, accompanied by dizziness and vertigo near fire, this was caused by Wind Qi sinking into the Blood aspect, failing to ascend and emerge. The treatment was also San Bi Tang with Wu Tou removed, added with Qiang Huo (Notopterygii Rhizoma) and Ma Huang (Ephedrae Herba). Women who have a history of depression should soothe the Liver Qi; use Xiao Yao San (Free and Easy Wanderer Powder) added with Qi-tonifying and Damp-draining herbs.
Xue Lizhai treated Liu Mengchun, who had Phlegm, causing numbness in both arms and tearing from both eyes. After taking wind-dispelling and Phlegm-resolving medicines, the Phlegm worsened, the arms became painful and unable to extend, and the fingers contracted. Xue said: "Numbness belongs to Qi Deficiency. Due to previous medications, the Liver was further injured, leading to excessive Fire and tendon contraction. Moreover, Wind arises from Fire. One should tonify the Spleen and Lung and nourish Water (Kidney Yin), so that Wind will naturally recede and Phlegm clear." Thus, Liu Wei Wan (Six-Ingredient Pill with Rehmannia) and Bu Zhong Yi Qi Tang were used, resulting in recovery after three months.
Shi Wan treated the wife of a foreign merchant, Ba Ciming. Postpartum, she suffered from vertigo and palpitations, with her Spirit and Soul scattered, appearing as if her Zang-Fu organs had lost their support. Upon opening her eyes, her whole body felt numb, as if floating in clouds and mist; she had to keep her eyes tightly closed to feel slightly better. She was irritable during the day and quiet at night. A gynecologist prescribed Si Wu Tang (Four Substance Decoction) and other blood-nourishing medicines, causing vomiting, regurgitation, and loss of appetite. Another doctor prescribed hot medicines like Jiang (Zingiberis Rhizoma) and Fu Zi (Aconiti Radix), causing restlessness and agitation. Her pulse was deficient, large, and rapid; upon deep pressure, it was scattered and rootless, while upon light pressure, it responded to the finger. This indicated floating and dispersing Heart Fire. Due to difficult labor and fright, Phlegm-Fluid invaded the Pericardium Collateral vacuously and lingered above the Diaphragm, entering but not exiting, thus prolonging the illness. Generally, when eyes open, all orifices open; Phlegm-Fire blocks the Heart orifices, causing the Spirit to lose mastery. When eyes close, all orifices close; Phlegm-Fire lies dormant and does not move, allowing for slight relief. This is distinctly different from the numbness described by Li Dongyuan where Yang Qi fails to circulate upon closing eyes. Moreover, since symptoms are worse during the day and lighter at night, it is clearly a disease in the Upper Jiao (Yang position). Treatment involved Phlegm-regulating and Fire-clearing agents, which gradually calmed the symptoms. However, due to fright or anger, or improper diet, attacks occurred frequently because the Phlegm lurking above the Diaphragm could not be thoroughly searched out and eliminated. During an attack, Du Shen Tang (Single Ginseng Decoction) was used to administer Zi Xue Dan (Purple Snow Pellet) to open the Diaphragm membrane, followed by the previous medicines. After half a year of regulation and tonification, she recovered.
