人参 山药 地黄 当归 枸杞 枣皮 甘草 杜仲
血，有形之阴也，可行可敛。气，无形之阳也，可升可降。今症候危剧，精神失守，气血俱大坏矣。坏则与
升降行敛之剂，皆不相投。故以甘平之人参、山药、甘草，杜仲补其真阳。以滋润之地黄、枸杞、枣皮、当归，
补其真阴。阴阳平补，则无形、有形互为赞化。济屯履夷，大都此为先着。
诗曰∶草长山皆药，人归地正黄，醇醪煎枣杞，烂醉杜家庄。
地黄（八两） 山药 枸杞 枣皮 菟丝子（ 极熟） 当归 鹿茸膏（炙） 龟胶（各四两） 杜仲（炒去丝） 牛
漆（各三两） 附子 肉桂（各二两）
两肾，皆水也。由左右言之，乃有阴阳之分焉。故左虚则火不安其位而妄动，燔灼真阴，发为咳喘衄咯，腰
肢酸软，心跳不宁。右虚则水无制而洋溢，反克脾土，发为膨胀翻胃，泄泻不时，小水频作，虚淋寒疝，肢节痹
痛，跗肿面浮，神疲气怯，食减增寒。乃用地黄、枣皮、枸杞、当归、牛膝、龟胶味浓质润之品，以滋左肾元阴，
山药、菟丝、杜
仲、附子、肉桂、鹿茸甘平辛温之品，以培右肾元阳。阴阳足，则精血潜充，神气倍旺，是谓两肾在位。两肾在
位则水火有所归矣。故曰左右合归。
诗曰∶桂地伏菟龟，杜陵产牛鹿，杞子附谁归，山山药可 。
血，是有形的阴质，可以运行也可以收敛；气，是无形的阳质，可以上升也可以下降。如今病症危急严重，精神失守，气血都受到了极大的损伤。既然已经败坏，那么与升降、行散、收敛的药物都不相契合。因此，使用甘平性质的人参、山药、甘草、杜仲来补益真阳。使用滋润性质的地黄、枸杞、山茱萸、当归来补益真阴。阴阳得到平和的补益，那么无形的气和有形的血就能互相资助化生。度过艰难险阻，大多以此作为首要措施。
诗曰：草长山皆药，人归地正黄，醇醪煎枣杞，烂醉杜家庄。
地黄（八两）、山药、枸杞、山茱萸、菟丝子（极熟）、当归、鹿茸膏（炙）、龟胶（各四两）、杜仲（炒去丝）、牛膝（各三两）、附子、肉桂（各二两）。
两个肾脏，都属于水脏。从左右而言，则有阴阳的区别。所以左侧肾虚则火不能安守其位而妄动，焚烧灼伤真阴，引发咳嗽气喘、鼻衄咯血、腰部肢体酸软、心跳不宁。右侧肾虚则水失去制约而泛滥，反而克制脾土，引发腹胀水肿、翻胃、不时泄泻、小便频数、虚淋寒疝、肢节痹痛、足背浮肿面部浮肿、神疲气怯、食欲减退怕冷增加。于是使用地黄、山茱萸、枸杞、当归、牛膝、龟胶等味道浓厚质地滋润的药物，来滋补肾左元阴；使用山药、菟丝子、杜仲、附子、肉桂、鹿茸等甘平辛温的药物，来培补肾右元阳。阴阳充足，则精血暗中充盈，神气加倍旺盛，这叫做两肾在位。两肾在位，则水火有所归宿。所以称为“左右合归”。

Ren Shen (Ginseng Radix), Shan Yao (Dioscoreae Rhizoma), Di Huang (Rehmanniae Radix), Dang Gui (Angelicae Sinensis Radix), Gou Qi Zi (Lycii Fructus), Zao Pi (Corni Fructus), Gan Cao (Glycyrrhizae Radix et Rhizoma), Du Zhong (Eucommiae Cortex).
Blood is substantial yin; it can circulate and be astringed. Qi is insubstantial yang; it can ascend and descend. Currently, the symptoms are critical and severe, with the spirit losing its residence, and both qi and blood severely damaged. Once damaged, they do not respond to agents of ascending/descending, moving, or astringing. Therefore, Ren Shen, Shan Yao, Gan Cao, and Du Zhong, which are sweet and neutral, are used to tonify True Yang. Di Huang, Gou Qi Zi, Zao Pi, and Dang Gui, which are moistening and nourishing, are used to tonify True Yin. When yin and yang are balanced and tonified, the insubstantial and the substantial mutually assist in transformation and generation. To navigate through adversity, this is largely the primary step.
The poem states: "Grass grows, mountains become medicine; people return, earth turns yellow. Mellow wine decocts dates and goji; drunk at Du's manor."
Di Huang (8 liang), Shan Yao, Gou Qi Zi, Zao Pi, Tu Si Zi (very well cooked), Dang Gui, Lu Rong Gao (Cervum Cornu Gelatum, prepared), Gui Jiao (Testudinis et Chelonis Carapax et Plastrum, each 4 liang), Du Zhong (stir-fried to remove silk fibers), Niu Xi (Achyranthis Bidentatae Radix, each 3 liang), Fu Zi (Aconiti Lateralis Radix Praeparata), Rou Gui (Cinnamomi Cortex, each 2 liang).
Both kidneys belong to water. Speaking from left and right, there is a distinction between yin and yang. Thus, if the left kidney is deficient, fire fails to remain in its proper position and moves recklessly, scorching and burning True Yin, manifesting as cough and asthma, epistaxis and hemoptysis, soreness and weakness of the waist and limbs, and palpitations with restlessness. If the right kidney is deficient, water lacks control and overflows, counter-acting Spleen Earth, manifesting as distension and swelling, regurgitation, intermittent diarrhea, frequent urination, deficiency-type strangury, cold hernia, bi-syndrome pain in joints, edema of the dorsum of feet and face, mental fatigue and qi timidity, decreased appetite, and increased aversion to cold. Therefore, substances with strong flavors and moist textures such as Di Huang, Zao Pi, Gou Qi Zi, Dang Gui, Niu Xi, and Gui Jiao are used to nourish the Original Yin of the left kidney. Substances that are sweet, neutral, acrid, and warm such as Shan Yao, Tu Si Zi, Du Zhong, Fu Zi, Rou Gui, and Lu Rong are used to cultivate the Original Yang of the right kidney. When yin and yang are sufficient, essence and blood secretly fill up, and spirit and qi double in vigor; this is called "both kidneys in their proper positions." When both kidneys are in their proper positions, water and fire have their归宿 (return/home). Hence, it is called "Left and Right Return Together" (Zuo You He Gui).
The poem states: "Gui, Di, Fu, Tu, Gui; Du Ling produces Niu and Lu; Qi Zi, Fu, who returns? Shan Shan Yao can..."
