补中益气汤 （见类中风章节）。
腰痛，有风邪所致，有寒邪所致，有湿邪所致，有热邪所致，有瘀血所致，有气滞所致，有痰饮所致，这些都属于标证，肾虚才是其根本原因。
腰部疼痛且拘急，牵引腿足，脉象浮弦的，是风邪；腰部冷如冰，喜欢用热手熨烫，脉象沉迟，或紧的，是寒邪，均用独活汤主治。
腰部疼痛如同坐在水中，身体沉重，腰间感觉像带着重物，脉象濡细的，是湿邪，用苍白二陈汤加独活主治。
如果腰部沉重疼痛，腰间发热，肢体痿软无力，脉象弦数的，是湿热，恐怕会发展成痿症，前方加黄柏主治。
如果是因闪挫跌扑导致，瘀血积于体内，转身侧卧时痛如刀锥刺入，大便黑色，脉象涩，或芤的，是瘀血，用泽兰汤主治。
疼痛走窜刺痛，忽聚忽散，脉象弦急的，是气滞，用橘核丸主治。
腰部肿胀，按压柔软不痛，脉象滑的，是痰，用二陈汤加白术、萆薢、白芥子、竹沥、姜汁主治。
腰痛感觉要脱出，重按稍止，脉象细弱无力的，是虚证，用六君子汤加杜仲、续断主治。
如果兼有阴冷症状，再辅以八味丸。
大抵腰痛都归属于肾虚，既然夹杂了邪气，必须祛除邪气，如果没有外邪，则只需补肾而已。
然而肾虚之中，又必须分辨寒热两证，如脉象虚软无力，小便清长，大便溏薄，腰间冷痛，这是阳虚，必须补命门之火，则用八味丸。
如果脉象细数无力，大便干结，小便赤黄，虚火时时炎上，这是肾气热，髓减骨枯，恐怕会发展成骨痿，此为阴虚，必须补先天之水，则用六味丸，合补阴丸之类，不可误用热药以灼伤阴液，治疗者务必审慎。

Decoct in water and take orally.
If accompanied by cold pathogen, add Aconiti Lateralis Radix Praeparata (Fu Zi) and Cinnamomi Ramulus (Gui Zhi).
Buzhong Yiqi Tang (See under Stroke-like Syndromes).
Loin pain may be caused by wind, cold, dampness, heat, blood stasis, qi stagnation, or phlegm-fluid retention; these are all branch manifestations (biao), while kidney deficiency is the root (ben).
Loin pain with stiffness and spasm, radiating to the legs and feet, with a floating and wiry pulse indicates wind; loins feeling cold as ice, preferring hot hand compressions, with a deep, slow, or tight pulse indicates cold. Both are primarily treated with Duhuo Tang.
Loin pain as if sitting in water, heavy body sensation, feeling of a heavy weight around the waist, with a soggy and fine pulse indicates dampness. This is primarily treated with Cangbai Erchen Tang added with Duhuo.
If there is heaviness and pain in the loins, heat sensation in the waist, flaccidity and weakness, with a wiry and rapid pulse, it indicates damp-heat. There is a risk of developing Wei Syndrome (flaccidity syndrome); add Phellodendri Cortex (Huang Bo) to the previous formula for treatment.
If caused by sprains, falls, or trauma, with blood stasis accumulating internally, turning movements causing stabbing pain like knife or awl pricks, black stools, and a choppy or hollow pulse, it indicates blood stasis. This is primarily treated with Zelan Tang.
Stabbing pain that migrates, appearing and disappearing suddenly, with a wiry and urgent pulse indicates qi stagnation. This is primarily treated with Juhe Wan.
Swelling in the loins, soft upon pressure without pain, with a slippery pulse indicates phlegm. This is treated with Erchen Tang added with Atractylodis Macrocephalae Rhizoma (Baizhu), Dioscoreae Hypoglaucae Rhizoma (Bixie), Brassicae Semen (Baijiezi), Bamboo Juice (Zhuli), and Ginger Juice (Jiangzhi).
Loin pain feeling as if dislocated, relieved slightly by firm pressure, with a fine, weak, and forceless pulse indicates deficiency. This is primarily treated with Liujunzi Tang added with Eucommiae Cortex (Duzhong) and Dipsaci Radix (Xuduan).
If accompanied by yin-cold symptoms, supplement with Bawei Wan.
Generally, loins pain is attributed to kidney deficiency. If accompanied by pathogenic factors, they must be expelled; if no external pathogens exist, only tonification of the kidney is required.
However, within kidney deficiency, one must distinguish between cold and heat syndromes. If the pulse is deficient and soft, urine is clear, stool is loose, and loins are cold and painful, this is Yang deficiency. One must tonify the Fire of Mingmen, using Bawei Wan.
If the pulse is fine, rapid, and forceless, stool is dry, urine is red, and defervescence fire flares up intermittently, this is Kidney Qi Heat leading to marrow depletion and bone withering, risking Gu Wei Syndrome (bone flaccidity). This is Yin deficiency. One must tonify the Primordial Water, using Liuwei Wan combined with Buyin Wan, etc. Do not mistakenly use hot medicines to scorch the Yin. Practitioners must exercise caution.
