入房太甚，宗筋纵驰，发为阴痿者，此方主之。
肾，坎象也。一阳居于二阴为坎，故肾中有命门之火焉。凡人入房甚而阴事作强不已者，
水衰而火独治也。阴事柔痿不举者，水衰而火亦败也。丹溪曰∶天非此火不足以生万物，人
非此火不能以有生，奈之何而可以无火乎？是方也，附子、肉桂，味浓而辛热，味浓则能入
阴，辛热则能益火，故能入少阴而益命门之火。熟地黄、山茱萸，味浓而质润，味浓则能养
阴，质润则能壮水，故能滋少阴而壮坎中之水。水欲实，则泽泻、丹皮之咸酸，可以引而泻
之。水欲实，则山药、茯苓之甘淡，可以渗而制之。水火得其养，则肾官不弱，命门不败，
而作强之官得其职矣。
痿证大都主热，痹证大都主寒。然痿证亦有寒者，痹证亦有热者，此不可泥也。《内经》
曰∶淫气喘息，痹聚在肺。淫气忧思，痹聚在心。淫气遗溺，痹聚在肾。淫气之竭，痹聚在
肝。淫气肌绝，痹聚在脾。此五证者，非温药不足以疗之也，宜于天雄、附子、川乌、硫黄、
蜀椒、蛇床子、韭子、小茴香辈消息之。

肾，对应坎卦的象意。一阳爻居于两个阴爻之间构成坎卦，因此肾中蕴藏着命门之火。凡是房事过度且性功能亢进不止的人，是肾水亏虚而相火独旺所致。若是性功能减退、阴茎萎软不举，则是肾水亏虚且命门之火也衰败了。朱丹溪说：“天没有这火不足以化生万物，人没有这火不能维持生命，怎么能说可以没有火呢？”这个方子中，附子、肉桂，气味浓厚且性质辛热，气味浓厚就能进入阴分，辛热就能补益命火，所以能入少阴经而补益命门之火。熟地黄、山茱萸，气味浓厚且质地滋润，气味浓厚就能滋养阴液，质地滋润就能壮旺肾水，所以能滋补肾阴而壮旺坎宫中的真水。想要使肾水充实，就可以用泽泻、牡丹皮的咸味和酸味，来引导并泄去其中的邪气（或理解为通过利湿清热以存真阴）。想要使肾水充实，就可以用山药、茯苓的甘味和淡味，来渗湿并制约其偏胜。水火得到调养，那么肾脏的功能就不会衰弱，命门之火不会败坏，主管作强功能的器官就能各司其职了。
痿证大多以热证为主，痹证大多以寒证为主。然而痿证也有寒证，痹证也有热证，这是不可拘泥固定的。《黄帝内经》说：“淫邪之气导致喘息，痹邪聚集在肺。淫邪之气导致忧思，痹邪聚集在心。淫邪之气导致遗尿，痹邪聚集在肾。淫邪之气导致精气竭绝，痹邪聚集在肝。淫邪之气导致肌肉萎缩，痹邪聚集在脾。”这五种证候，不用温性药物不足以治疗，适宜在天雄、附子、川乌、硫黄、蜀椒、蛇床子、韭子、小茴香这类药物中斟酌选用。
序言说：六经都有厥证，大率都是火邪所致。现在列举杂病中的厥证数条，以展示其大体情况。如果是伤寒引起的阴厥、阳厥，应当在《伤寒方考》中寻求答案。
Prepared Rehmannia Root (Shu Di Huang, *Rehmanniae Radix Praeparata*) (8 liang)
Cornus Fruit (Shan Zhu Yu, *Corni Fructus*) (pitted)
Chinese Yam (Shan Yao, *Dioscoreae Rhizoma*) (4 liang each)
Moutan Bark (Mu Dan Pi, *Moutan Cortex*) (woody parts removed)
Poria (Bai Fu Ling, *Poria*)
Alisma Rhizome (Ze Xie, *Alismatis Rhizoma*) (3 liang each)
This formula is indicated for cases of impotence (Yin Wei, 阴痿) caused by excessive sexual intercourse leading to flaccidity of the sinews of the genitalia.
The Kidney corresponds to the Kan trigram (Kan Xiang, 坎象). Kan is formed by one Yang line situated between two Yin lines; thus, the Fire of the Gate of Life (Ming Men Huo, 命门之火) resides within the Kidney. In individuals who engage in excessive sexual activity and experience persistent hypersexuality or forced erection, this indicates a deficiency of Kidney Water allowing the Ministerial Fire to dominate alone. Conversely, if there is flaccidity and inability to erect, it signifies that both Kidney Water is deficient and the Fire of the Gate of Life is also failing. Zhu Danxi stated: "Without this Fire, Heaven cannot generate all things; without this Fire, humans cannot sustain life. How can one claim that Fire is unnecessary?" In this formula, Aconite Root (Fu Zi, *Aconiti Lateralis Radix Praeparata*) and Cinnamon Bark (Rou Gui, *Cinnamomi Cortex*), being pungent, hot, and possessing strong flavors, penetrate into the Yin aspect. Their pungency and heat tonify the Fire; therefore, they enter the Shaoyin channel and augment the Fire of the Gate of Life. Prepared Rehmannia Root and Cornus Fruit, being rich in flavor and moist in nature, nourish Yin and strengthen Water; thus, they tonify the Shaoyin and reinforce the True Water within the Kan palace. To solidify the Water, the salty and sour properties of Alisma Rhizome and Moutan Bark can guide and drain excesses (or clear damp-heat to preserve true Yin). To consolidate the Water, the sweet and bland properties of Chinese Yam and Poria can leach out dampness and restrain imbalance. When Water and Fire are properly nurtured, the function of the Kidney organ remains robust, the Fire of the Gate of Life does not fail, and the official responsible for strength and vigor fulfills its duties.
Wei syndrome (Atrophy Syndrome, 痿证) is predominantly characterized by Heat, while Bi syndrome (Obstruction Syndrome, 痹证) is predominantly characterized by Cold. However, Wei syndrome may also present with Cold, and Bi syndrome may present with Heat; one must not adhere rigidly to these generalizations. The *Neijing* states: "When pathogenic factors cause panting, the Bi pathogen gathers in the Lung. When they cause worry and rumination, the Bi pathogen gathers in the Heart. When they cause enuresis, the Bi pathogen gathers in the Kidney. When they cause exhaustion of essence, the Bi pathogen gathers in the Liver. When they cause muscle atrophy, the Bi pathogen gathers in the Spleen." These five patterns require warming herbs for treatment; one should judiciously select from herbs such as Tianxiong (*Aconiti Kusnezoffii Radix*), Aconite Root (Fu Zi), Chuanwu (*Aconiti Radix*), Sulfur, Shuzhuo (*Zanthoxyli Pericarpium*), Shechuangzi (*Cnidii Fructus*), Jiuzi (*Allii Tuberosi Semen*), and Xiaohuixiang (*Foeniculi Fructus*).
Preface: Jue syndrome (Jue Zheng, 厥证) exists in all six channels, generally arising from Fire. Here, several cases of Jue syndrome from miscellaneous diseases are presented to illustrate the major principles. For Yin Jue and Yang Jue resulting from Cold Damage (Shanghan, 伤寒), please refer to *Yi Fang Kao* on Shanghan formulas.
