麻木之症，有但麻而不木者，有麻木兼作者，麻为轻而木为重；木则不知痛痒寒热，即经所谓不

肌肉，脉理不通而致者，宜参治痹方治之。亦有因气虚，因血少，因气滞，因死血，因湿痰之不一，各
有的症可凭，详审投剂，庶不致误。
养阴清热润燥汤〔见燥。〕治血液苦涩，虚火作麻，甚则不仁。
原方宜加甘菊 首乌 秦艽之属，手臂麻木，宜桑枝煎汤代水，两足麻木加牛膝。
补中益气汤〔见泄泻。〕果属气虚麻木者，主此加减。
顺气开痰饮〔见中风。〕治肺气郁滞不行麻木者，加减用之。
犀角地黄汤〔见伤寒。〕果属瘀血停留中宫，气滞不行于四肢作麻木者用之。
原方宜加桃仁 红花 降香之属。

原方宜加苍术 天麻 胆星之属。
此五方审其所因而用之。按东垣言麻木是气不行所致，

一、有一位妇女患痹症，右手连同手臂和肩膀肿痛，无法活动。我使用治疗行痹的主方，经过加减治疗后没有痊愈。后来改用草乌来搜风胜湿祛寒，苍术、白术燥湿，当归养血荣身，乳香、没药活血散瘀，止痛消肿，各取一两研成粉末，每次服用五分，用陈年黄酒调服，每天服用两次。（如果感到麻木，喝米汤即可停止；若不麻木则逐渐增加剂量至一钱为止。）服药完毕而痊愈。
二、有一位男子胸中不适长达一年，无法准确描述其症状。朱丹溪（朱震亨）给他服用栝蒌薤白汤，一剂药后痊愈。
麻木的症状，有只麻不木的，也有麻木并发的，麻较轻而木较重；木则不知痛痒寒热，也就是《内经》所说的“不仁”。有的因风邪伤及卫气，气机凝滞不行而导致；有的因寒邪伤及营血，皮肤失去濡养（无血以调和）而导致；有的因湿邪伤及肌肉，脉理不通而导致，适宜参考治疗痹症的方剂进行治疗。也有因气虚、血少、气滞、死血（瘀血）、湿痰等原因不一而致的，各有具体的症状可以凭据，详细审察后投药，才不会导致误治。
养阴清热润燥汤（见燥证章节）治疗血液枯涩，虚火引起麻木，严重时出现不仁。
原方适宜加入甘菊、首乌、秦艽这类药物；若手臂麻木，宜用桑枝煎汤代替水煎药；若两足麻木，加牛膝。
补中益气汤（见泄泻章节）如果是确实属于气虚引起的麻木，以此方为主进行加减。
顺气开痰饮（见中风章节）治疗肺气郁滞不行导致的麻木，加减后使用。
犀角地黄汤（见伤寒章节）如果是确实属于瘀血停留于中焦（脾胃），气滞不行于四肢导致麻木者使用。
原方适宜加入桃仁、红花、降香这类药物。
二陈汤（见中风章节）如果是确实属于湿痰停留，气滞不行导致麻木者使用。
原方适宜加入苍术、天麻、胆南星这类药物。
这五个方子要审查病因后选用。按李东垣的说法，麻木是气机不行所致，适宜疏利肺气，开散郁滞。另外朱丹溪说：麻是气虚，木属于湿痰、死血。我认为瘦弱之人麻木，多因血液枯涩，虚火所致。
《内经》说：营气虚则不仁（不知痛痒）。卫气虚则不用（不能举动）。营卫俱虚则既不知痛痒又不能举动，但肌肉外形如故。人身与意志不相联系（身体不与五志相关联），称为死。
1. A female patient suffered from Bi syndrome (Obstruction Syndrome), with swelling and pain in her right hand, arm, and shoulder, rendering it immobile. I initially used the principal formula for Xing Bi (Wandering Bi Syndrome) with modifications, but it was ineffective. Subsequently, I switched to using Caowu (Aconitum kusnezoffii Rhizome) to search out wind, overcome dampness, and dispel cold; Cangzhu (Atractylodis Rhizoma) and Baizhu (Atractylodis Macrocephalae Rhizoma) to dry dampness; Danggui (Angelicae Sinensis Radix) to nourish the blood and promote nutrition; and Ruxiang (Olibanum) and Moyao (Myrrha) to invigorate blood, dissipate stasis, relieve pain, and reduce swelling. Each herb was processed into powder at a dosage of one liang. The patient took five fen per dose, mixed with aged yellow wine, twice daily. [If numbness is felt, drinking rice soup will stop it; if no numbness occurs, gradually increase the dose up to one qian.] After completing the course, she recovered.
2. A male patient had experienced chest discomfort for over a year and could not describe his condition accurately. Zhu Danxi (Zhu Zhenheng) prescribed Gualou Xiebai Tang (Trichosanthes and Macrostemon Decoction), and he recovered after one dose.
The symptom of numbness includes cases of only tingling without anesthesia, and cases where both occur together. Tingling is mild, whereas anesthesia is severe; anesthesia implies insensitivity to pain, itching, cold, and heat, which corresponds to the concept of "Bu Ren" (Insensibility) mentioned in the classics. Some cases are caused by wind damaging the Wei Qi (Defensive Qi), leading to stagnation and failure of circulation; some are caused by cold damaging the Ying Blood (Nutritive Blood), resulting in skin malnutrition [due to lack of blood to harmonize]; some are caused by dampness damaging the muscles, leading to blocked meridians and tissues. These should be treated with reference to formulas for Bi syndrome. Other causes include Qi deficiency, Blood deficiency, Qi stagnation, fixed blood stasis, and damp-phlegm. Each has specific symptoms for reference. Careful examination before prescribing ensures no errors.
Yangyin Qingre Runzao Tang (Nourishing Yin, Clearing Heat, and Moistening Dryness Decoction) [see section on Dryness] treats numbness caused by bitter-dry blood and deficient fire, progressing to insensibility.
It is advisable to add Ganju (Chrysanthemi Flos), Shouwu (Polygoni Multiflori Radix), and Qinjiao (Gentianae Macrophyllae Radix) to the original formula. For arm numbness, use Sangzhi (Toosendan Fructus or Mulberry Twig) decoction as water for brewing herbs. For leg numbness, add Niuxi (Achyranthis Bidentatae Radix).
Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) [see section on Diarrhea] is the principal formula with modifications for numbness caused by Qi deficiency.
Shunqi Kaitan Yin (Regulating Qi and Opening Phlegm Infusion) [see section on Stroke] is used with modifications for numbness caused by stagnation and failure of Lung Qi circulation.
Xijiao Dihuang Tang (Rhinoceros Horn and Rehmannia Decoction) [see section on Cold Damage] is used for numbness in the limbs caused by blood stasis lingering in the Middle Jiao (Spleen and Stomach) and Qi stagnation failing to circulate to the extremities.
It is advisable to add Taoren (Persicae Semen), Honghua (Carthami Flos), and Jiangxiang (Dalbergiae Odoriferae Lignum) to the original formula.
Erchen Tang (Two-Aged Decoction) [see section on Stroke] is used for numbness caused by damp-phlegm lingering and Qi stagnation failing to circulate.
It is advisable to add Cangzhu (Atractylodis Rhizoma), Tianma (Gastrodiae Rhizoma), and Danning (Arisaematis Cum Bile) to the original formula.
These five formulas should be selected based on the etiology. According to Li Dongyuan, numbness is caused by the failure of Qi circulation; thus, it is appropriate to regulate Lung Qi and disperse stagnation. Furthermore, Zhu Danxi stated: Tingling is due to Qi deficiency, while anesthesia belongs to damp-phlegm and fixed blood stasis. I believe that in emaciated individuals, numbness is mostly caused by dry-bitter blood and deficient fire.
The Classics state: Ying Qi deficiency leads to Bu Ren (insensibility) [inability to feel pain or itch]. Wei Qi deficiency leads to Bu Yong (inability to move) [inability to actuate]. When both are deficient, there is insensibility and inability to move, yet the flesh remains normal in appearance. When the body and the mind/will are disconnected [the body does not respond to the Five Emotions], it is termed death.
