〔手足之痛者，人以为脾经之热，不知非脾热也，乃肝木之郁结也。散其郁气，则手足之痛自去矣。〕方用
逍遥散加∶
栀子（三钱） 半夏（二钱） 白芥子（二钱）
水煎服。
二剂其痛如失。盖肝木作祟，脾气不敢当其锋，气散于四肢，结而不伸，所以作楚。今一旦平其肝气，则脾气
自舒矣。〔脾气舒而痛在手足，有不尽除者乎？〕
足弱
此病不能步履，人以为肾水之虚，谁知由于气虚而不能运动乎？方用补中益气汤加∶
牛膝（三钱） 石斛（五钱） 黄 （一两） 人参（三钱）
水煎服。
〔三剂即足生力，四剂可以步履矣。盖人参、 术，皆补气之圣药，而牛膝、石斛，亦健足之神剂，所以用之
而历成也。〕
筋缩
凡人一身之筋脉，不可有病，病则筋缩而身痛，脉涩而体重矣。然筋之舒在于血和，而脉之平则于气足。故
治筋必须先治血，而治脉必须先补气。人若筋急拳缩，伛偻而不能立，俯仰而不能直者，皆筋病也。方用∶
当归（一两） 白芍（五钱） 薏仁（五钱） 生地（五钱） 元参（五钱） 柴胡（一钱）
水煎服。
此方奇在用柴胡一味，入于补血药中，盖血亏则筋病，用补血药以治筋宜矣，何以又用柴胡以散之？不知肝
为筋之主，筋乃肝之余，肝气不顺，筋自缩急，〔甚而伛偻〕，今用柴胡以舒散之，郁气既除，而又济之大剂补
血之品，则筋自得其养〔而宽，筋宽则诸症悉愈矣。〕
手足疼痛，人们通常认为是脾经有热，却不知并非脾热所致，而是肝气郁结造成的。只要疏散了郁滞的气机，手足的疼痛自然就会消除。方剂选用逍遥散，并加入以下药物：栀子（三钱）、半夏（二钱）、白芥子（二钱）。用水煎煮后服用。服用两剂后，疼痛便如消失一般。这是因为肝木之气作祟，脾气不敢承受其锋芒，导致气机散乱于四肢，凝结而不能舒展，所以产生疼痛。如今一旦平抑了肝气，脾气自然就能舒畅。[脾气舒畅了，而疼痛表现在手足，难道还有不能彻底消除的吗？]
足部软弱无力
这种病症表现为无法行走，人们通常认为是肾水亏虚，谁知其实是由于气虚导致无法运动呢？方剂选用补中益气汤，并加入以下药物：牛膝（三钱）、石斛（五钱）、黄芪（一两）、人参（三钱）。用水煎煮后服用。[服用三剂后脚上就会产生力量，四剂之后就可以行走了。因为人参、白术，都是补气的神圣药物，而牛膝、石斛，也是强健足部的神奇药剂，所以使用它们能够屡次取得成效。]
筋脉拘挛
一个人全身的筋脉，不能有疾病，一旦生病就会导致筋脉拘挛收缩而身体疼痛，脉象涩滞且身体沉重。然而，筋脉的舒展在于血液调和，而脉道的平和则依赖于气的充足。因此，治疗筋病必须先调理血液，而治疗脉病必须先补益元气。如果人出现筋脉紧急、手握拳收缩、弯腰曲背无法站立、前俯后仰无法挺直的情况，这些都是筋的病证。方剂选用：当归（一两）、白芍（五钱）、薏苡仁（五钱）、生地黄（五钱）、玄参（五钱）、柴胡（一钱）。用水煎煮后服用。
这个方子的奇妙之处在于单独使用柴胡一味药，将其放入补血药物之中。大概是因为血虚会导致筋病，使用补血药来治疗筋病是适宜的，为什么又要用柴胡来疏散呢？殊不知肝是筋的主宰，筋是肝之余气所化，肝气不顺，筋自然会收缩紧急，[甚至导致弯腰曲背]，如今使用柴胡来舒散它，郁滞的气机既然已经去除，又辅以大剂量的补血药物，那么筋脉自然得到滋养[而变得宽松，筋脉宽松了，各种症状就全部痊愈了。]
Pain in the Hands and Feet
When there is pain in the hands and feet, people generally attribute it to Heat in the Spleen Meridian (Spleen Channel), not realizing that it is not due to Spleen Heat, but rather to the stagnation and knotting of Liver Wood (Liver Qi Stagnation). Once the stagnant Qi is dispersed, the pain in the hands and feet will naturally disappear. The prescription used is Xiaoyao San (Free and Easy Wanderer Powder) with additions: Gardenia (Zhi Zi, 3 qian), Pinellia Rhizome (Ban Xia, 2 qian), White Mustard Seed (Bai Jie Zi, 2 qian). Decoct in water and take orally. After two doses, the pain disappears as if it had never existed. This is because the mischievous influence of Liver Wood prevents the Spleen Qi from bearing its full force; the Qi scatters into the four limbs, knots up, and fails to extend, thus causing pain. Now that the Liver Qi has been pacified, the Spleen Qi naturally becomes comfortable. [If the Spleen Qi is comfortable, and the pain is located in the hands and feet, how could it fail to be completely eliminated?]
Weakness of the Feet
This condition, characterized by the inability to walk, is usually attributed to Deficiency of Kidney Water (Kidney Yin/Essence). Who would know that it actually stems from Qi Deficiency leading to an inability to move? The prescription used is Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) with additions: Achyranthes Root (Niu Xi, 3 qian), Dendrobium Stem (Shi Hu, 5 qian), Astragalus Root (Huang Qi, 1 liang), Ginseng Root (Ren Shen, 3 qian). Decoct in water and take orally. [After three doses, strength returns to the feet; after four doses, walking becomes possible. This is because Ren Shen and Bai Zhu are supreme herbs for tonifying Qi, while Niu Xi and Shi Hu are miraculous agents for strengthening the feet; hence, their use leads to repeated success.]
Tendon Contraction
The tendons and vessels of the entire body must not suffer from disease. If they do, the tendons contract, causing body pain, a choppy pulse, and a sensation of heaviness in the body. However, the relaxation of tendons depends on the harmony of Blood, while the smoothness of vessels relies on sufficient Qi. Therefore, treating tendon disorders requires first regulating Blood, and treating vessel disorders requires first tonifying Qi. If a person exhibits tight tendons, clenched fists, kyphosis (stooped posture) preventing standing, and an inability to straighten the body when bending forward or backward, these are all disorders of the tendons. The prescription used is: Angelica Sinensis Root (Dang Gui, 1 liang), White Peony Root (Bai Shao, 5 qian), Coix Seed (Yi Yi Ren, 5 qian), Rehmannia Root Preparata (Sheng Di Huang, 5 qian), Scrophularia Root (Xuan Shen, 5 qian), Bupleurum Root (Chai Hu, 1 qian). Decoct in water and take orally.
The ingenuity of this formula lies in the single addition of Chai Hu within blood-nourishing herbs. Generally, Blood Deficiency leads to tendon disorders, so using blood-tonifying herbs to treat them is appropriate. Why add Chai Hu to disperse? It is unknown that the Liver is the master of tendons, and tendons are the surplus of the Liver. When Liver Qi is unsmooth, the tendons naturally contract and tighten, [even leading to kyphosis]. Now, by using Chai Hu to soothe and disperse, the stagnant Qi is removed, and this is supplemented with large doses of blood-nourishing substances. Consequently, the tendons receive nourishment [and become relaxed; once the tendons are relaxed, all symptoms are cured.]
