Zhu Danxi stated: The pulse must be deep (Chen) and wiry (Xian). A deep pulse indicates stagnation, while a wiry pulse indicates deficiency. A choppy pulse (Se) signifies blood stasis; a slow pulse (Huan) signifies dampness; a slippery pulse (Hua) that is hidden (Fu) signifies phlegm; and a large pulse (Da) signifies Kidney deficiency.
The waist is the mansion of the Kidneys. If movement is difficult, it indicates that the Kidneys are on the verge of exhaustion. This results from unregulated desires and labor injuring the Kidney meridian, often compounded by emotional factors such as anger, joy, worry, and thought, as well as external pathogens like wind, cold, dampness, and toxins invading the body. Consequently, lower back pain occurs, radiating to the spine and back, extending to the hypochondrium on both sides, making flexion and extension impossible. This is caused by the weakness of Kidney Qi. It is appropriate to nourish the Kidneys and regulate Qi, after which the disease can be eliminated.
First discussion: Frequent lower back pain indicates Kidney deficiency. This formula is indicated.
Bushen Tang (Kidney-Nourishing Decoction)
Danggui (Angelicae Sinensis Radix, washed with wine), Baishao (Paeoniae Radix Alba, stir-fried with wine), Shengdihuang (Rehmanniae Radix), Shudihuang (Rehmanniae Radix Preparata), Chenpi (Citri Reticulatae Pericarpium), Xiaohuixiang (Foeniculi Fructus, stir-fried with salt and wine), Poguozhi (Psoraleae Fructus, stir-fried with wine), Niuxi (Achyranthis Bidentatae Radix, remove radicle, washed with wine), Duzhong (Eucommiae Cortex, remove rough bark, stir-fried with wine), Baifuling (Poria, remove skin, each 1 qian), Renshen (Ginseng Radix et Rhizoma, 5 fen), Huangbai (Phellodendri Cortex, remove bark, washed with wine), Zhimu (Anemarrhenae Rhizoma, stir-fried with wine, each 7 fen), Gancao (Licorice Root, honey-fried, 3 fen).

For daily maintenance, process into pills: grind all ingredients into fine powder, mix with refined honey to form pills the size of paulownia seeds.

Crush these ingredients, add three slices of fresh ginger, decoct in water, and take orally. For severe pain, add Xurong (Boswelliae Resina) and Moyao (Myrrhae Resina), each ground to 5 fen powder. If water-dampness fails to descend, add Heiqiu (Pharbitidis Semen) and Binglang (Arecae Semen), each 5 fen. For blood-related pain, add Guiwei (Angelicae Sinensis Radix), Taoren (Persicae Semen, remove skin and tip), each 1 qian, and Honghua (Carthami Flos, washed with wine), 5 fen. For pain caused by cold wind, add Shufuzi (Aconiti Lateralis Radix Preparata), 1 qian, and Hu Jinggu Mo (Tiger Tibia Bone Powder), 5 fen; remove Huangbai and Zexie, each 3 fen. For fatigue and a sensation of heaviness in the legs as if falling, add Cangzhu (Atractylodis Rhizoma), Fangji (Stephaniae Tetrandrae Radix), Yiyiren (Coicis Semen), and Baizhu (Atractylodis Macrocephalae Rhizoma), each 5 fen.

Stir-fry fish bladder until it turns into charcoal beads. Quench it in one bowl of good liquor. When warm, consume the liquid along with the residue in one go.
Fifth discussion: This formula specifically nourishes Kidney Water, strengthens Original Yang, benefits sinews and bones, darkens hair, and is highly effective for Kidney-deficiency lower back pain and knee/foot pain.
Qing'e Wan (Green Wall Pill)

Grind into fine powder, mix with refined honey to form pills the size of paulownia seeds. Take 80 pills per dose, on an empty stomach, downed with wine.
Sixth discussion: Weakness of Kidney Qi allows Liver and Spleen Qi to invade, causing pain in the waist and knees, difficulty in flexion and extension, cold bi-syndrome, and weakness. The Kidney is a Water organ; when deficient, Liver and Spleen Qi converge there, causing fullness and pain in the waist and knees. Difficulty in flexion and extension indicates pathology in both sinews and bones. The Classics state: "Ability to flex but not extend indicates pathology in sinews; ability to extend but not flex indicates pathology in bones." Thus, difficulty in flexion and extension is a disease of sinews and bones. Cold bi-syndrome indicates excess Yin pathogenic factors; weakness indicates deficiency of Qi and Blood. Use Duhuo Jisheng Tang (See "Zhong Shi" chapter).
Seventh discussion: Weakness of Original Qi, lower back pain with white turbid urine. Use Buzhong Yiqi Tang (See "Nei Shang" chapter), modified by adding Huangbai (Phellodendri Cortex), Zhimu (Anemarrhenae Rhizoma), and Baishao (Paeoniae Radix Alba), all stir-fried with wine. Niuxi (Achyranthis Bidentatae Radix) should have its radicle removed and be washed with wine. Duzhong (Eucommiae Cortex) should be stir-fried with ginger and wine.

Grind into powder. Take 2 qian per dose. Cut open a pig kidney, insert the powder inside, wrap in paper, roast over fire until cooked. Chew thoroughly and swallow with wine.
Ninth discussion: Regarding lower back pain, people often treat it as Kidney deficiency, but if various medicines fail, this is pain due to blood stasis. Use Banliang (half tael) of Dahuang (Rhei Radix et Rhizoma), plus Banliang of Shengjiang (Zingiberis Rhizoma Recens). Chop them together into pieces the size of small beans. Stir-fry in a pot until yellow. Add two bowls of water, decoct, and take in one dose at dawn (Wugeng). By morning, expel the blood stasis from the waist using a basin.
