人有终日举阳，绝不肯倒，然一与女合，又立时泄精，精泄之后，随又兴起，人以为
命门之火，谁知阴衰之极乎。夫阴阳原两相平者也。无阳则阴脱而精泄，无阴则阳孤而势举，
二者皆能杀人。彼此相较，阴脱之症骤而死，阳孤之病缓而死。似乎骤而死者难治，缓而
死者易医。而孰知阴脱之症，其阳不绝，补阳可以摄阴；阳孤之病，其阴已涸，补阴难以制
阳。盖阳生阴甚速，阴接阳甚迟，故脱阴留阳者，往往可援，孤阳无阴者，每每不救耳。虽
然阴根于阳，补阳而阴可生，安在阳不根阴，而补阴即不能生阳乎。使强阳不倒之人，尚
有一线之阴在，则阴必可续而可生，阴既生矣，则阳不为孤阳，阴日旺而阳日平，谁谓非
死里求生之妙法乎。方用平阳汤∶
玄参（三两） 山茱萸（一两） 沙参（二两） 地骨皮（一两） 丹皮（一两）水煎
服。连服二剂，而阳不甚举矣。又服四剂，阳又少衰矣。再服四剂，阳平如故。
此方纯是补阴之药，更能凉其骨中之髓。又恐过于纯阴，与阳有格格不入之意，
复加入山茱萸，阴中有阳也，使其引阴入阳，以制其太刚之气，真善于制刚也。倘见其火旺
之极，妄用黄柏、知母以寒凉折之，毋论水不可以灭火，反激动其龙雷之怒，阴不能入于阳
之中，阳反离夫阴之外，有不至于死亡而不可得也。
此症亦可用济阳汤治之。
熟地（二两） 玄参 麦冬 沙参（各一两）久服自安。
人有终日操心，勤于诵读，作文之时，刻苦搜索，及至入房，又复鼓勇酣战，遂至阳举
不倒，胸中烦躁，口中作渴，两目红肿，饮之以水不解，人以为阳旺之极，谁知心肾二火
之齐动乎。夫心肾无一刻不交，心交于肾，则肾火无飞腾之祸∶肾交于心，则心火无亢烈之
忧。若日劳其心，则心不交于肾；夜劳其肾，则肾亦不交于心。心肾不交，则水火无既济
之好，觉一身上下，无非火气，于是心君失权，肾水无力，而命门之火与心包之火反相合而
不相离，骨中髓动，髓海煎熬，肝中龙雷之火亦起而相应，三焦之火亦且附和，以助其炎上
之势，火尽上升，阳无所寄，势不得不仍归于下，下又难藏，因走于宗筋阴器之间，阳乃作
强而不可倒矣。此等之病，至危之症也，非迅解二火，阳何能倒。然解火又禁用寒凉以直
折其火，盖二火乃虚
火，而非实火。惟有引火归经，少用微寒之品，以退其浮游之火，则火自归源，而鲜决裂
之虞。方用引火两安汤∶
玄参（一两） 麦冬（二两） 丹皮（五钱） 沙参（一两） 黄连（一钱） 肉桂（
一钱）水煎服。一剂而火少衰，二剂而阳乃倒矣。连服四剂，而火乃定。减黄连、肉桂各
用三分，再服数剂，两火不再动矣。
此方补阴以退阳，补阴之中又无腻重之味，得黄连、肉桂同用，以交心肾，心肾合而水
气生，水气生而火自解。况玄参、麦冬、沙参又是退火之味，仍是补水之品，所以能退其浮游
之火，解其亢阳之祸也。
此症亦可用加减济心丹∶
人参炒枣仁（各五钱） 熟地 玄参 麦冬 丹皮（各一两） 莲子心 茯苓（各三钱）
水煎服。四剂即安。
有人整天阴茎勃起，绝不肯疲软，然而一旦与女子交合，便立即泄精，精液泄出之后，随即又兴起。人们认为是命门之火（肾阳）旺盛，却不知道这是阴气衰败到了极点。阴阳原本应当是平衡的。没有阳气，阴就会脱失而精液外泄；没有阴气，阳气就会孤立无援而持续勃起，这两种情况都能致人死亡。比较二者，阴气脱失的病证发作急骤而死，阳气孤立的病证发展缓慢而死。似乎急骤死亡的难治，缓慢死亡的易医。然而谁知道阴气脱失的病证，其阳气尚未断绝，补益阳气可以固摄阴气；而阳气孤立的病证，其阴气已经枯竭，补益阴气难以制约阳气。因为阳气生发迅速，阴气接续缓慢，所以阴脱而阳留的情况，往往可以挽救；而阳孤无阴的情况，每每无法救治。虽然阴根源于阳，补阳而生阴，但难道阳不根源于阴吗？如果补阴就不能生阳吗？假如强阳不倒的人，尚存一线阴气，那么阴气必然可以接续并生长，阴气既已生长，那么阳气就不再是孤阳，阴气日益旺盛而阳气日益平和，这难道不是死里求生的妙法吗？方用平阳汤：玄参（三两）、山茱萸（一两）、沙参（二两）、地骨皮（一两）、丹皮（一两），水煎服。连服两剂，阳气就不怎么勃起了。再服四剂，阳气又稍微衰退了。又服四剂，阳气恢复平和如常。
此方纯粹是补阴的药物，更能凉清骨髓中的热邪。又担心过于纯阴，与阳气有格格不入之意，所以加入山茱萸，它是阴中有阳的药，使其引导阴气进入阳气之中，以制约其过于刚强的气势，真是善于制约刚强啊。倘若见到火势极旺，妄用黄柏、知母等寒凉药物来直折其火，不用说水不能灭火，反而会激动龙雷之火（相火妄动），阴气不能入于阳气之中，阳气反而脱离阴气之外，以至于死亡都是不可避免的。
此症也可以用济阳汤治疗。熟地（二两）、玄参、麦冬、沙参（各一两），久服自然安宁。
有人整天操劳心神，勤于诵读，写文章时刻苦搜索思绪，等到进入房事时，又鼓足勇气酣战，导致阴茎勃起不倒，胸中烦躁，口中作渴，双眼红肿，喝水也不能解渴。人们认为是阳气旺盛到了极点，却不知道这是心火和肾火同时发动。心和肾没有一刻不相互交通的，心气下交于肾，则肾火就没有飞腾为祸的危险；肾气上交于心，则心火就没有亢烈为忧的隐患。如果白天劳损心神，则心气不交于肾；夜晚劳损肾精，则肾气也不交于心。心肾不交，则水火不能既济（心肾相交），感觉全身上下无非都是火气，于是心君失去权柄，肾水无力，而命门之火与心包之火反而相合而不分离，骨髓动摇，髓海被煎熬，肝中的龙雷之火也起来相应，三焦之火也附和助长其炎上的势头，火气全部上升，阳气无处寄托，势必要回归到下焦，下焦又难以藏纳，因此流注于宗筋（男性生殖器）之间，阳气于是表现为强盛而不能倒伏。这种病，是极其危险的症候，如果不迅速解除心肾二火，阳气怎么能倒伏呢？然而解火又禁止使用寒凉药物来直接折损其火，因为这两处火是虚火，而不是实火。只有采用引火归经的方法，少量使用微寒的药物，以退去浮游之火，则火自然回归本源，而很少有决裂的危险。方用引火两安汤：玄参（一两）、麦冬（二两）、丹皮（五钱）、沙参（一两）、黄连（一钱）、肉桂（一钱），水煎服。一剂后火势稍减，两剂后阳气就倒伏了。连服四剂，火势就安定下来。减少黄连、肉桂各用三分，再服几剂，两处火气就不再动了。
此方通过补阴来消退阳气，在补阴之中又没有滋腻厚重的药味，得到黄连、肉桂同用，以交通心肾，心肾合一而水气产生，水气产生而火气自然解散。况且玄参、麦冬、沙参又是退火的药味，仍是补水的产品，所以能退去浮游之火，解除亢阳之祸。
此症也可以用加减济心丹治疗：人参、炒枣仁（各五钱）、熟地、玄参、麦冬、丹皮（各一两）、莲子心、茯苓（各三钱），水煎服。四剂即见安宁。
A person may have a penis that remains erect all day long, never willing to become flaccid. However, upon copulation with a woman, semen is ejaculated immediately. After ejaculation, the erection rises again. People attribute this to the fire of the Mingmen (Gate of Life), but little do they know it is actually extreme deficiency of Yin. Yin and Yang should originally be in balance. Without Yang, Yin will escape and semen will leak; without Yin, Yang will stand alone and remain erect. Both conditions can be fatal. Comparing the two, the syndrome of Yin escape leads to sudden death, while the disease of Yang isolation leads to slow death. It seems that sudden death is difficult to treat, while slow death is easier to cure. Yet who knows that in the syndrome of Yin escape, Yang is not yet exhausted, so tonifying Yang can secure Yin; whereas in the disease of Yang isolation, Yin has already dried up, so tonifying Yin cannot easily control Yang. Since Yang generates quickly and Yin connects slowly, cases of Yin escape leaving Yang often can be rescued, while cases of isolated Yang without Yin are frequently incurable. Although Yin roots in Yang, and tonifying Yang can generate Yin, how can it be said that Yang does not root in Yin? If tonifying Yin cannot generate Yang? If a person with persistent erection still has a thread of Yin remaining, then Yin can surely be continued and generated. Once Yin is generated, Yang will no longer be isolated. As Yin flourishes daily, Yang becomes peaceful daily. Who would say this is not a wonderful method for seeking life from death? The formula used is Pingyang Tang: Xuan Shen (3 liang), Shan Zhu Yu (1 liang), Sha Shen (2 liang), Di Gu Pi (1 liang), Dan Pi (1 liang). Decoct in water and take orally. After taking two doses consecutively, the erection was no longer very frequent. After taking four more doses, the erection decreased slightly. After another four doses, the erection returned to normal peace.
This formula consists purely of Yin-tonifying herbs, which can also cool the marrow in the bones. Fearing that pure Yin might clash with Yang, Shan Zhu Yu is added because it contains Yang within Yin, guiding Yin into Yang to restrain its excessive rigidity. This is truly skillful in controlling rigidity. If one sees extreme fire prosperity and recklessly uses Huang Bo or Zhi Mu to extinguish the fire with cold-natured herbs, not only will water fail to extinguish fire, but it will also agitate the Dragon-Lei Fire (hyperactive ministerial fire). Yin will fail to enter Yang, and Yang will separate from Yin, leading inevitably to death.
This condition can also be treated with Jiyang Tang: Shu Di (2 liang), Xuan Shen, Mai Dong, Sha Shen (each 1 liang). Long-term use will bring natural peace.
A person who worries constantly, studies diligently, and searches hard for ideas when writing essays, then engages vigorously in sexual intercourse, may suffer from persistent erection, chest irritability, thirst, red and swollen eyes, and drinking water provides no relief. People think this is extreme Yang prosperity, but little do they know it is simultaneous movement of Heart Fire and Kidney Fire. The Heart and Kidney interact at all times. When Heart Qi descends to the Kidney, Kidney Fire has no danger of soaring; when Kidney Qi ascends to the Heart, Heart Fire has no worry of hyperactivity. If the Heart is labored during the day, Heart Qi does not descend to the Kidney; if the Kidney is labored at night, Kidney Qi does not ascend to the Heart. When Heart and Kidney do not interact, Water and Fire cannot achieve Ji Ji (mutual interaction). One feels nothing but fire throughout the body. Thus, the Heart Monarch loses authority, Kidney Water lacks strength, and the Mingmen Fire and Pericardium Fire merge and do not separate. The marrow moves, the Sea of Marrow is scorched, the Dragon-Lei Fire in the Liver rises in response, and the Sanjiao Fire joins in to assist its upward-burning momentum. All fire qi rises, leaving Yang nowhere to lodge. Forced to return downward, it finds the lower Jiao unable to store it, so it flows between the Zongjin (genitals). Yang thus becomes strong and cannot fall. This is a critically dangerous condition. Unless the two fires are rapidly resolved, how can Yang fall? However, resolving fire prohibits using cold-natured herbs to directly suppress it, because these two fires are Deficient Fire, not Excess Fire. Only by guiding fire back to its meridian and using a small amount of mildly cold herbs to retreat floating fire can the fire return to its source, avoiding rupture risks. The formula used is Yinghuo Liang'an Tang: Xuan Shen (1 liang), Mai Dong (2 liang), Dan Pi (5 qian), Sha Shen (1 liang), Huang Lian (1 qian), Rou Gui (1 qian). Decoct in water and take orally. After one dose, fire decreases slightly; after two doses, Yang falls. After four consecutive doses, fire stabilizes. Reduce Huang Lian and Rou Gui to 3 fen each, and take several more doses until the two fires no longer move.
This formula tonifies Yin to retreat Yang, without heavy or cloying substances in the Yin-tonification. With Huang Lian and Rou Gui used together, they facilitate Heart-Kidney interaction. When Heart and Kidney unite, Water Qi generates; when Water Qi generates, Fire naturally resolves. Moreover, Xuan Shen, Mai Dong, and Sha Shen are herbs that reduce fire and nourish water, enabling them to retreat floating fire and resolve the disaster of hyperactive Yang.
This condition can also be treated with Jiajian Jixin Dan: Ren Shen, Chao Suan Zao Ren (each 5 qian), Shu Di, Xuan Shen, Mai Dong, Dan Pi (each 1 liang), Lian Zi Xin, Fu Ling (each 3 qian). Decoct in water and take orally. Peace is achieved in four doses.
