猪膏 姜汁（各二升，熬取三升再入酒） 酒（五合）
和煎，分三服。
五劳之外，又称六极。筋极之状，令人数转筋，十指爪甲皆痛，苦倦不能久立，宜此方
主之。
筋极者，数劳四肢，筋液耗竭，名曰筋极。极者，甚于劳之名也。筋既竭其津液，则失
其润养，而作劲急，故令人数转筋也。爪甲，筋之余也，筋属木，木极则金承之，故令十指
爪甲皆痛，亦枝枯萌萎之象也。苦倦不能久立者，筋败不能束骨也。是疾也，若以草木之药
治之，卒难责效。师曰∶膏以养筋，故假猪膏以润养之。等以姜汁者。非辛不足以达四末故
也。复熬以酒者，以酒性善行，能浃洽气血，无所不之，故用之以为煎也。

脉极者，忽忽喜忘，少颜色，眉发堕落，此方主之。
脉者，血之府。脉极者，血脉空虚之极也，此由失血所致。心主血脉，脉极则无血以养
心，故令忽忽喜忘。荣血有余，则令人悦泽颜色，荣血不足，则令人色夭而颜色少也。眉发
者，血之所养，养血不足，故令眉发堕落。人参、黄 、白术、茯苓、甘草、陈皮，皆补气
药也，荣血不足而补气，此《大易》之教，阴生于阳之义也。阴者，五脏之所主，故用当归
泽脾，芍药调肝，熟地滋肾，五味益肺，远志宁心，五脏和而阴血自生矣。桂性辛热，热者
入心而益火，辛者入经而利血，又心为生脉之原，故假之引诸药入心而养荣血于脉耳。
猪膏、姜汁（各二升，熬煮浓缩至三升，再加入酒） 酒（五合）
混合煎煮，分三次服用。
除了五劳之外，又有所谓的六极。筋极的症状，表现为频繁发生转筋（肌肉痉挛），十个手指和脚趾的指甲都疼痛，极度疲倦无法长时间站立，适宜用此方主治。
所谓筋极，是因为四肢过度劳累，导致筋的津液耗竭，称为筋极。“极”是比“劳”更严重的名称。筋既然耗尽了津液，就失去了滋润和濡养，从而变得强劲急迫，所以会导致频繁转筋。爪甲是筋的余气所生，筋在五行中属木，木气过极则金气来克制它，所以十个手指和脚趾的指甲都会疼痛，这也是枝条干枯、萌芽萎谢的景象。极度疲倦无法长时间站立的，是因为筋衰败不能约束骨骼。这种疾病，如果用草木类的药物治疗，很难迅速见效。老师说：膏脂可以滋养筋，所以借用猪膏来润养它。加入姜汁的原因，是因为没有辛味不足以通达四肢末端。再用酒煎煮，是因为酒性善于运行，能使气血周流全身，无处不到，所以用它来作为煎药介质。

脉极的症状，表现为神情恍惚、容易遗忘，面色无华，眉毛头发脱落，此方主治。
脉是血液汇聚的府库。脉极，是血脉空虚到了极点，这通常由失血引起。心主血脉，脉极则没有血液来滋养心脏，所以导致神情恍惚、容易遗忘。营血充足，就会让人面色红润光泽；营血不足，就会让人面色枯槁、气色黯淡。眉毛和头发，是由血液滋养的，养血不足，所以导致眉毛头发脱落。人参、黄芪、白术、茯苓、甘草、陈皮，都是补气药。在营血不足时补益气，这是《易经》教导的，阴生于阳的道理。阴，由五脏所主宰，所以用当归润泽脾脏，芍药调理肝脏，熟地黄滋补肾脏，五味子补益肺脏，远志宁心安神，五脏调和而阴血自然生成。桂心性味辛热，热性入心而助益心火，辛味入经脉而利于血液运行，而且心是生成脉气的本源，所以借助它引导诸药进入心脏，从而在脉中滋养营血。
Pig fat (Su Gao) and Ginger juice (Jiang Zhi) (each two sheng, boiled down to three sheng, then add wine) Wine (Wu he)
Mix and decoct, divide into three doses.
Beyond the Five Exhaustions (Wu Lao), there is also the concept of the Six Extremities (Liu Ji). The manifestation of Sinew Extremity (Jin Ji) involves frequent muscle spasms (Zhuan Jin), pain in all ten fingernails and toenails, severe fatigue making it impossible to stand for long periods; this formula is indicated for such conditions.
Sinew Extremity refers to the depletion of sinew fluids due to excessive labor of the four limbs, termed "Sinew Extremity." "Extremity" denotes a condition more severe than "Exhaustion." Since the sinews have exhausted their fluids, they lose their moistening and nourishing properties, becoming stiff and tense, thus causing frequent spasms. Nails are considered the surplus of sinews. Sinews belong to Wood in the Five Elements; when Wood reaches its extremity, Metal acts upon it, resulting in pain in all fingernails and toenails, resembling withered branches and fading buds. Severe fatigue preventing prolonged standing occurs because the sinews are too debilitated to bind the bones. This disease, if treated with herbal medicines alone, is difficult to cure quickly. The Master said: Fatty substances nourish sinews, hence Pig fat is used to moisten and nourish them. Ginger juice is added because pungency is required to reach the extremities. Wine is used for decoction because wine has a nature that promotes circulation, allowing Qi and Blood to permeate throughout the body without restriction; thus, it is used as the medium for decoction.

The manifestations of Pulse Extremity (Mai Ji) include mental fogginess, forgetfulness, lackluster complexion, and falling eyebrows and hair; this formula is indicated.
The vessels (Mai) are the reservoirs of blood. Pulse Extremity represents the utmost emptiness of the blood vessels, often caused by blood loss. The Heart governs the blood vessels; when the vessels are at an extreme of emptiness, there is insufficient blood to nourish the Heart, leading to mental fogginess and forgetfulness. When Ying-Blood (Nutritive Blood) is sufficient, it gives a lustrous and healthy complexion; when Ying-Blood is deficient, it results in a sallow and dull complexion. Eyebrows and hair are nourished by blood; deficiency in nourishing blood leads to their loss. Ren Shen, Huang Qi, Bai Zhu, Fu Ling, Gan Cao, and Chen Pi are all Qi-tonifying herbs. Tonifying Qi when Ying-Blood is deficient follows the teaching of the *I Ching* (Book of Changes): Yin arises from Yang. Yin is governed by the Five Viscera; therefore, Dang Gui is used to moisten the Spleen, Bai Shao Yao to regulate the Liver, Shu Di Huang to nourish the Kidney, Wu Wei Zi to benefit the Lung, and Yuan Zhi to calm the Heart. When the Five Viscera are harmonized, Yin-Blood generates naturally. Gui Xin is acrid and hot; heat enters the Heart to augment Fire, and acridity enters the channels to promote blood flow. Moreover, the Heart is the origin of pulse generation; thus, Gui Xin is employed to guide the other herbs into the Heart to nourish Ying-Blood within the vessels.
