干姜 茯苓（各四钱） 炙甘草 白术（炒，各二钱）
肾着于湿，腰冷如冰，若有物者，此方主之。
肾主水，脾主湿，湿胜则流，必归于坎者势也，故曰肾着。腰为肾之府，湿为阴之气，
故令腰冷如冰；若有物者，实邪着之也。干姜，辛热之物，辛得金之燥，热得阳之令，燥能
胜湿，阳能暴湿，故象而用之。白术、甘草，甘温之品也，甘得土之味，温得土之气，土胜
可以制湿，故用以佐之。白茯苓，甘淡之品也，甘则益土以防水，淡则开其窍而利之，此围
师必缺之义也。
猪腰（一具） 青盐（三钱） 杜仲（末，五钱）
先将猪腰剖开，后入青盐、杜仲于内，湿纸包裹煨熟，空心服之。
小小腰痛，此方主之。
《易》曰∶方以类取，物以群分。故猪腰可以补腰。经曰∶五味入口，咸先入肾。故青
盐可以就下。杜仲辛甘，益肾之物也。君以猪腰，佐以青盐，则直走肾而补之矣。
叙曰∶疝，隐疾也。证有七，七者皆有虚实。今考七方，志七疝耳。若虚实之辨，则在
夫人之变通也。
吴茱萸 生姜（各三钱） 人参（一钱） 大枣（二枚） 附子（二钱）
水煎凉服。
寒疝腰痛，牵引睾丸，屈而不伸，尺内脉来沉迟者，此方主之。
故称七疝，寒、水、筋、血、气、狐、 也。寒疝之由，必是寒客下体，如坐于卑冷，
涉于寒渊之所致也。寒气自外入内，束其少火，郁其肝气，故令腰痛；痛而牵引睾丸者，肝
之经络环阴器故也。寒主收引，故令屈而不伸。尺内主腰，脉来沉迟，皆阴脉也，寒亦明矣。
故用吴茱萸、附子之辛热者以温其寒，用生姜、大枣之辛温者以和其气。邪伤之后，其正必
虚，人参之补，可以去其虚矣。
Dried Ginger (Shengjiang), Poria (Fuling) (each 4 qian); Roasted Licorice Root (Zhigancao), Atractylodes Macrocephala Rhizome (Baizhu) (stir-fried, each 2 qian).
Shenzhuo disease (a condition where cold-dampness lingers in the region of the Kidney) is caused by dampness. The waist feels cold as ice, and there is a sensation of an object attached to it; this formula is indicated for such cases.
The Kidney governs water, and the Spleen governs dampness. When dampness prevails, it flows and inevitably returns to the Kan (Water) trigram/organ, which is its natural tendency; hence it is called "Shenzhuo" (Lingering in the Kidney). The waist is the mansion of the Kidney, and dampness is a Yin pathogen.
Therefore, it causes the waist to feel cold as ice; the sensation of an object attached is due to the lingering of excess pathogens. Dried Ginger is a pungent and hot substance. Its pungency corresponds to the dryness of Metal, and its heat corresponds to the command of Yang. Dryness can overcome dampness, and Yang heat can rapidly dispel dampness; thus, it is used based on the principle of taking images (Xiang). Atractylodes Macrocephala Rhizome and Licorice Root are sweet and warm substances. Their sweetness corresponds to the flavor of Earth, and their warmth corresponds to the Qi of Earth. When Earth Qi is strong, it can control dampness; therefore, they are used to assist in treatment. White Poria is a sweet and bland substance. Sweetness tonifies Earth to prevent Water overflow, and blandness opens orifices to promote diuresis; this reflects the strategy of leaving a gap when besieging an enemy.
Pig Kidney (one piece), Green Salt (Qingyan) (3 qian), Eucommia Bark (Duzhong) (powdered, 5 qian).
First, split the pig kidney open, then insert the Green Salt and Eucommia powder inside. Wrap it in wet paper and bake/cook until done. Take on an empty stomach.
This formula is indicated for mild lower back pain.
The *I Ching* states: "Things are selected by category, and objects are grouped by kind." Therefore, pig kidney can tonify the waist. The medical classics state: "When the five flavors enter the mouth, salty flavor enters the Kidney first." Therefore, Green Salt can guide the medicine downward. Eucommia is pungent and sweet, a substance that benefits the Kidney. Using pig kidney as the sovereign herb and Green Salt as the assistant/herb, the medicinal power goes directly to the Kidney to tonify it.
Preface: Hernia (Shan) is a hidden ailment. There are seven types of syndromes, and all seven have deficiency and excess patterns. Here, we examine the Seven Forms to record the seven types of hernias. As for distinguishing between deficiency and excess, it depends on the physician's flexibility and adaptation.
Evodia Fruit (Wuzhuyu), Fresh Ginger (Shengjiang) (each 3 qian), Ginseng Root (Renshen) (1 qian), Jujube (Dazao) (two pieces), Prepared Aconite Root (Fuzi) (2 qian).
Decoct in water and take cool.
Cold hernia accompanied by lower back pain, radiating to the testicles, with the legs bent and unable to extend, and a deep and slow pulse at the Chi position; this formula is indicated.
Hence the term "Seven Hernias," referring to Cold Hernia, Water Hernia, Sinew Hernia, Blood Hernia, Qi Hernia, Fox Hernia, and Scrotal Hernia. The cause of Cold Hernia must be cold pathogens lodging in the lower body, akin to sitting in a low, cold place or wading into a cold abyss. Cold Qi enters from the exterior into the interior, binding the Lesser Fire and stagnating Liver Qi, thus causing lower back pain. The pain radiating to the testicles occurs because the Liver meridian circles the genitalia. Cold governs contraction and pulling, thus causing the legs to bend and not extend. The Chi position governs the waist; a deep and slow pulse are both Yin pulses, clearly indicating Cold.
Therefore, the pungent and hot properties of Evodia Fruit and Prepared Aconite Root are used to warm and dispel cold. The pungent and warm properties of Fresh Ginger and Jujube are used to harmonize Qi. After injury by pathogens, the healthy Qi must be deficient; the tonifying action of Ginseng Root can remove this deficiency.
