禀阳气之肥，得金气之浓，故味辛、甘，气平，微温，无毒。入足少阴兼入足厥
阴经，功专肝肾，故所主治皆筋骨之病，专用补肾，淡盐酒拌炒。若同调补筋骨药用，
则生用，或酒炒；若同祛湿除痹药用，以姜酒拌炒。同滋补药则益筋骨之气血，同祛风
药则去筋骨之风湿，总所主不离筋骨也。
杜仲，益肾添精，治腰脊疼痛难伸，补中强志，止梦遗，小便余沥，助肝肾，坚筋
骨，除阴痒，去囊湿，痿痹瘫软必需，脚痛不能践地立效，补肾气，润肝燥。牛膝主下
部血分，杜仲主下部气分，故每相须为用，东垣云∶杜仲能使筋骨相着。
按∶杜仲性温而不助火，可以久服，功专肾肝二经，直走下部，筋骨气分，牛膝直
走下部经络血分，熟地滋补肾肝筋骨精髓之内，续断调补筋骨曲节气血之间，故数味每
相须为用，以为筋骨气血之需，互相佐使成功也。
柏感秋令，最深得金气独浓，固凌冬不凋，其质坚而气极芬芳，故其实味甘，平，
无毒。入足厥阴少阴，亦入手少阴经，专治心肾两虚，且芬芳则脾胃所喜，润泽则肝肾
俱宜，五脏皆安，气血自益，湿痹除而颜色美，自可轻身延年矣。叶味苦微温无毒，宜
春采东，夏采南，秋采西，冬采北，补益用九蒸九晒，止血用宜炒黑，以苦温之性，则
祛湿痰痹，除热止血之功、独擅其长矣。
柏实，入心养神，入肝定志养气血。去恍惚虚损。敛汗聪耳，却风寒湿痹止痛，治
肾冷腰冷，并膀胱冷脓宿水，润肾燥体燥，及面颜燥涩不光，历节腰中重痛，兴阳道，
辟百邪，止惊悸，安五脏，头风眩痛，亦可煎调，久服润泽肌肤，不饥不老，延年轻
身，惟肠胃滑利者勿用。侧柏叶须照令采方，止吐衄崩痢，系补阴要药，兼燥湿仙
丹，若合黄连煎服，小儿虫痢立痊，肢节酿酒，主历节风痹，并人畜疥癞。
按∶柏叶生而向西，禀兑金之正气，能制肝木，木主升，金主降，升降相配，夫妇
之道和，则血得以归肝，故仲景治吐血不止。然气味与血分无情，不过仗金气以制
木，借炒黑以止红耳，岂可用以调补气血，长养精神矣！
杜仲禀受阳气之充沛，得金气之浓厚，因此味道辛、甘，气性平，微温，无毒。它入足少阴肾经，兼入足厥阴肝经，功效专于肝肾，所以主治的都是筋骨方面的疾病，专门用于补肾，通常用淡盐水拌炒。如果与调理补益筋骨的药物同用，则生用，或用酒炒；如果与祛湿除痹的药物同用，则用姜酒拌炒。与滋补药同用，则能增益筋骨的气血；与祛风药同用，则能去除筋骨的风湿，总之其主治范围不离筋骨。
杜仲，能益肾添精，治疗腰脊疼痛难以伸展，补益中气、强固意志，止梦遗、小便余沥不尽，助益肝肾，坚固筋骨，消除阴部瘙痒，去除阴囊湿气，痿证、痹证、瘫痪软弱必需此药，脚痛不能站立行走有立竿见影之效，补肾气，润肝燥。牛膝主要作用于下部血分，杜仲主要作用于下部气分，所以二者常相须为用。李东垣说：杜仲能使筋骨紧密结合。
按语：杜仲性温而不助火，可以长期服用，功效专入肾、肝二经，直走下部，作用于筋骨气分；牛膝直走下部经络血分；熟地黄滋补肾肝筋骨精髓之内；续断调补筋骨关节气血之间，所以这几味药常常相须为用，作为筋骨气血的需求，互相佐使以取得成功。
柏树感应秋令，最深地得到金气且最为浓厚，所以凌冬不凋谢，其质地坚硬而气味极芬芳，因此它的果实（柏实）味甘，性平，无毒。入足厥阴肝经、足少阴肾经，也入手少阴心经，专门治疗心肾两虚。因为气味芬芳是脾胃所喜好的，润泽则是肝肾都适宜的，五脏都能安宁，气血自然受益，湿痹除去而面色美好，自然可以轻身延年。柏树叶味苦，微温，无毒，适宜春季采东边的，夏季采南边的，秋季采西边的，冬季采北边的。用于补益需经过九蒸九晒，用于止血宜炒黑，凭借苦温的性质，在祛湿痰痹阻、清热止血方面独擅其长。
柏实，入心养神，入肝定志、养气血。去除恍惚、虚损。收敛汗液、聪耳，驱除风寒湿痹止痛，治疗肾冷、腰冷，以及膀胱冷积脓、宿水，润肾燥、身体燥，以及面部干燥涩滞无光泽，历节病腰中沉重疼痛，兴阳道，辟除百邪，止惊悸，安五脏，头风眩晕疼痛，也可以煎汤调服。长期服用润泽肌肤，不饥饿不衰老，延年轻身，只有肠胃滑利者不宜使用。侧柏叶必须按照季节采集才能见效，止吐血、衄血、崩漏、痢疾，是补阴的要药，兼作燥湿的仙丹。如果配合黄连煎服，小儿虫痢立即痊愈；肢节部位酿酒，主治历节风痹，以及人畜疥癞。
按语：柏叶生长时向西，禀受兑金之正气，能制约肝木。木主升，金主降，升降相互配合，夫妇之道和谐，则血液得以归藏于肝，所以张仲景治疗吐血不止。然而柏叶的气味与血分没有直接关系，不过是仗着金气来制约肝木，借助炒黑来止血罢了，怎么可以用来调补气血、长养精神呢！
Du Zhong (Eucommiae Cortex) absorbs abundant Yang Qi and dense Metal Qi, thus possessing a pungent and sweet taste, neutral nature, slightly warm property, and non-toxicity. It enters the Foot Shaoyin Kidney Meridian and concurrently the Foot Jueyin Liver Meridian. Its efficacy is specialized in the Liver and Kidney; therefore, its indications are all diseases of the sinews and bones, specifically used for tonifying the Kidney. It is typically stir-fried with light salt water. When combined with herbs that regulate and tonify sinews and bones, it is used raw or stir-fried with wine; when combined with herbs that dispel dampness and remove bi-syndrome, it is stir-fried with ginger and wine. Combined with tonifying herbs, it benefits the Qi and Blood of sinews and bones; combined with wind-dispelling herbs, it removes wind-dampness from sinews and bones. In summary, its indications never depart from sinews and bones.
Du Zhong (Eucommiae Cortex) benefits the Kidney and replenishes Essence, treats severe lower back and spinal pain with difficulty in extension, tonifies the Middle Jiao and strengthens willpower, stops nocturnal emission and dribbling urine, assists the Liver and Kidney, strengthens sinews and bones, eliminates genital itching, removes scrotal dampness, is essential for flaccidity, bi-syndrome, and paralysis/weakness, is effective for foot pain preventing standing/walking, tonifies Kidney Qi, and moistens Liver dryness. Huai Niu Xi (Achyranthis Bidentatae Radix) primarily governs the lower body's Blood aspect, while Du Zhong (Eucommiae Cortex) primarily governs the lower body's Qi aspect; thus, they are often used together as complementary agents. Li Dongyuan stated: "Du Zhong (Eucommiae Cortex) can cause sinews and bones to adhere closely."
Note: Du Zhong (Eucommiae Cortex) is warm but does not aid fire, allowing for long-term use. Its efficacy specializes in the Kidney and Liver meridians, acting directly on the lower body, specifically the Qi aspect of sinews and bones. Huai Niu Xi (Achyranthis Bidentatae Radix) acts directly on the lower body's meridian Blood aspect. Shu Di Huang (Rehmanniae Radix Preparata) nourishes the internal Essence and Marrow of the Liver and Kidney sinews and bones. Xu Duan (Dipsaci Radix) regulates and tonifies the Qi and Blood between the joints of sinews and bones. Therefore, these herbs are often used together as complementary agents to meet the needs of sinew and bone Qi and Blood, assisting each other to achieve success.
Cypress (Bai Zi) responds to the Autumn season, deeply receiving the most concentrated Metal Qi, remaining evergreen through winter. Its texture is hard and its aroma extremely fragrant; thus, its fruit (Bai Zi Ren) has a sweet taste, neutral nature, and is non-toxic. It enters the Foot Jueyin Liver Meridian, Foot Shaoyin Kidney Meridian, and also the Hand Shaoyin Heart Meridian. It specifically treats deficiency of both Heart and Kidney. Because its fragrance is pleasing to the Spleen and Stomach, and its moisture is suitable for both Liver and Kidney, the Five Zang Organs are pacified, and Qi and Blood naturally benefit. With damp-bi removed and complexion improved, one can naturally become lighter and prolong life. Cypress Leaf (Ce Bai Ye) tastes bitter, is slightly warm, and non-toxic. It is best harvested from the East in Spring, South in Summer, West in Autumn, and North in Winter. For tonification, it undergoes nine steaming and nine sun-drying processes; for stopping bleeding, it should be charred. Relying on its bitter-warm nature, it excels in dispelling damp-phlegm and bi-syndrome, clearing heat, and stopping bleeding.
Bai Zi Ren (Platycladi Semen) enters the Heart to nourish the Spirit, enters the Liver to stabilize will and nourish Qi and Blood. It eliminates mental confusion and deficiency wasting. It consolidates sweat and sharpens hearing, expels wind-cold-damp bi-syndrome and relieves pain, treats cold Kidney and cold lower back, as well as cold accumulation/pus and retained water in the Bladder, moistens Kidney dryness and bodily dryness, including dry, rough, and lusterless facial skin, heaviness and pain in the lumbar region associated with Bi syndrome affecting multiple joints (Li Jie), promotes sexual function, wards off various pathogens, stops palpitations/fright, and stabilizes the Five Zang Organs. For headache due to wind and vertigo/pain, it can also be decocted and taken. Long-term use moistens the skin, prevents hunger and aging, prolongs life, and lightens the body. However, it should not be used by those with loose bowels. Ce Bai Ye (Cupressi Cacumen) must be harvested according to the season to be effective. It stops hematemesis, epistaxis, metrorrhagia, and dysentery. It is an essential herb for tonifying Yin and a miraculous pill for drying dampness. If decocted with Huang Lian (Coptidis Rhizoma), pediatric worm-dysentery is cured immediately. Wine made from its branches/joints treats Li Jie wind-bi syndrome and scabies in humans and animals.
Note: Cypress leaves grow facing west, inheriting the righteous Qi of Dui Metal, which can restrain Liver Wood. Wood governs ascending, Metal governs descending. The coordination of ascending and descending harmonizes the relationship between husband and wife, allowing blood to return to the Liver. Therefore, Zhang Zhongjing used it for persistent hematemesis. However, its flavor and qi have no direct affinity with the Blood aspect; it merely relies on Metal Qi to restrain Wood and uses charring to stop red discharge (bleeding). How can it be used to regulate and tonify Qi and Blood, or to nurture spirit?
