偏风者，或左肢不遂，或右肢不遂。在左者为瘫，血虚也。右者为痪，气虚也。左瘫右痪者，气血两虚也。总宜先
灸百会，次灸合谷。如一偏疼痛，手臂不仁，拘挛难伸，灸手之里，兼灸腕骨。倘痛甚不能提物，灸肩 。两手挛痛，
臂细无力，灸曲池。半身不遂，灸环跳。按穴灸之，自然却病。
百会穴（见中风。）
合谷（大指次指歧骨间陷中，即虎口，两叉骨缝中。）
手三里（曲池下二寸锐骨端，按之肉起。）
腕骨（手外侧腕前起骨下陷中，即小指直上处。）
肩 （肩端两骨间。）
曲池（屈手按胸，肘弯横纹尖尽处）
环跳（见中风。）
眩，目花也。晕，头昏也。其病之因有五∶一曰无痰不眩，一曰无火不晕，一曰木动生风，一曰水不涵木，一曰土
虚木摇是也。医者莫分，药多罔效，灸神庭穴，自获安全。若未中机，再灸肝俞必验。
神庭（从鼻上直入发际五分，即眉心上三寸五分。）
肝俞（八节下，各开二寸。）
经曰∶肺热叶焦发为痿 ，痿 者，足软而不能步也。其症有五，不可不明。盖痿 属肺，脉痿属心，筋痿属肝，
肉
痿属脾，骨痿属肾也。总当先灸足三里，甚则灸三阴。灸法得宜，较汤散为胜也。
足三里（膝下三寸， 外廉，以手掌按膝头中指到处，股外旁也。膝盖骨下三寸，在 骨外廉两筋肉分宛宛中，平
坐垂足，取之在背，《金鉴》作大筋肉。）
三阴（足内踝上三寸，大骨下陷中。）
偏风，表现为左侧肢体活动不利，或右侧肢体活动不利。病位在左侧的称为“瘫”，属于血虚；病位在右侧的称为“痪”，属于气虚。若出现左瘫右痪的情况，则是气血两虚所致。治疗时总应先灸百会穴，再灸合谷穴。如果一侧肢体疼痛，手臂麻木不仁，拘挛难以伸展，应灸手三里穴，并兼灸腕骨穴。倘若疼痛剧烈到无法提举物品，应灸肩髃穴。若双手拘挛疼痛，手臂消瘦无力，应灸曲池穴。半身不遂者，应灸环跳穴。按照穴位进行艾灸，自然能够祛除疾病。
眩，是指视物昏花。晕，是指头部昏沉。导致眩晕病症的原因有五种：一是无痰则不眩，二是无火则不晕，三是肝木动摇而生内风，四是肾水不足不能涵养肝木，五是脾土虚弱导致肝木摇动。医生若不加以区分，用药往往无效。此时应灸神庭穴，自可获得安全疗效。如果尚未切中病机，再灸肝俞穴必定见效。
医经记载：肺热导致肺叶焦枯，从而引发痿证。痿证，是指足部软弱无法行走的症状。其症状表现主要有五种，不可不明确。大致而言，痿证归属于肺，脉痿归属于心，筋痿归属于肝，肉痿归属于脾，骨痿归属于肾。治疗时总应当先灸足三里穴，病情严重者则加灸三阴交穴。只要艾灸方法得当，效果胜过汤剂和散剂。
Pian Feng (Hemiplegia) manifests as motor impairment of the left limbs or the right limbs. When located on the left, it is termed "Tan" (flaccid paralysis), which is due to Blood Deficiency. When located on the right, it is termed "Huan" (spastic paralysis), which is due to Qi Deficiency. The condition of having Tan on the left and Huan on the right indicates a deficiency of both Qi and Blood. Generally, one should first moxa Baihui (DU20), followed by Hegu (LI4). If there is pain in one side, with numbness of the arm and hand, and spasms making extension difficult, moxibustion should be applied to Shousanli (LI10), combined with Mangu (SI4). If the pain is severe such that lifting objects is impossible, moxibustion should be applied to Jianyu (LI15). For spasmodic pain in both hands and arms that are thin and weak, moxibustion should be applied to Quchi (LI11). For hemiplegia, moxibustion should be applied to Huantiao (GB30). Applying moxibustion according to these acupoints will naturally dispel the disease.
Xuan (Vertigo/Dizziness) refers to blurred vision. Yun (Dizziness/Lightheadedness) refers to a sensation of head heaviness or spinning. There are five causes for this pathology: First, without Phlegm, there is no Xuan; Second, without Fire, there is no Yun; Third, Liver Wood stirring generates internal Wind; Fourth, Kidney Water fails to nourish Liver Wood; Fifth, Spleen Earth deficiency causes Liver Wood to shake. If physicians do not differentiate among these, medications often prove ineffective. In such cases, moxibustion on Shenting (DU24) will ensure safety and efficacy. If the treatment has not yet hit the mark, moxibustion on Ganshu (BL18) will certainly yield results.
The Classics state: Lung Heat causing the lung leaves to become scorched and dry leads to Wei Syndrome (Flaccidity Syndrome). Wei Syndrome refers to weakness of the feet preventing walking. Its symptoms fall into five categories, which must be clearly understood. Generally, Wei Syndrome belongs to the Lung, Mai Wei (Vessel Flaccidity) belongs to the Heart, Jin Wei (Tendon Flaccidity) belongs to the Liver, Rou Wei (Muscle Flaccidity) belongs to the Spleen, and Gu Wei (Bone Flaccidity) belongs to the Kidney. Treatment should always begin with moxibustion on Zusanli (ST36); in severe cases, Sanyinjiao (SP6) should also be moxa-ed. When the moxibustion method is appropriate, its efficacy surpasses that of decoctions and powders.
