心为诸脏主，其正经不可伤，伤之而痛者，则朝发夕死，夕发朝死，不暇展治。其久心
痛者，是心之支别络脉，为风邪冷热所乘痛也，故成疹不死，发作有时，经久不瘥也。
心与小肠，合为表里，俱象于火，而火为阳气也。心为诸脏主，故正经不受邪。若为邪
所伤而痛，即死。若支别络脉为风邪所乘而痛，则经久成疹。其痛悬急懊者，是邪迫于阳，
气不得宣畅，壅瘀生热，故心如悬而急，烦懊痛也。
心痛而多唾者，停饮乘心之络故也。停饮者，水液之所为也。心气通于舌，心与小肠合
，俱象火；小肠，心之腑也，其水气下行于小肠，为溲便，则心络无有停饮也。膀胱与肾俱
象水，膀胱为肾之腑，主藏津液；肾之液上为唾，肾气下通于阴，若腑脏和平，则水液下流
宣利；若冷热相乘，致腑脏不调，津液水饮停积，上迫于心，令心气不宣畅，故痛而多唾也
。
心痛而不能饮食者，积冷在内，客于脾而乘心络故也。心，阳气也；冷，阴气也。冷乘
于心，阴阳相乘，冷热相击，故令痛也。脾主消水谷，冷气客之，则脾气冷弱，不胜于水谷
也。心为火，脾为土，是母子也，俱为邪所乘，故痛，复不能饮食也。
腹痛者，由腑脏虚，寒冷之气，客于肠胃、募原之间，结聚不散，正气与邪气交争相击
，故痛。其有阴气搏于阴经者，则腹痛而肠鸣，谓之寒中。是阳气不足，阴气有余者也。
诊其寸口脉沉而紧，则腹痛。尺脉紧，脐下痛。脉沉迟，腹痛。脉来触触者，少腹痛。
脉阴弦，则腹痛。凡腹急痛，此里之有病，其脉当沉。若细而反浮大，故当愈矣。其人不即
愈者，必当死，以其病与脉相反故也。其汤熨针石，别有正方，补养宣导，今附于后。
《养生方·导引法》云∶治股、胫、手臂痛法∶屈一胫、臂中所痛者，正偃卧，口鼻闭
气，腹痛，以意推之，想气往至痛上，俱热即愈。
又云∶偃卧，展两胫、两手，仰足指，以鼻纳气，自极七息。除腹中弦急切痛。
又云∶正偃卧，以口徐徐纳气，以鼻出之。除里急。饱食后咽气数十，令温中；若气寒
者，使人干呕腹痛。口纳气七十所，大振腹；咽气数十，两手相摩，令热，以摩腹，令气下
又云∶偃卧，仰两足、两手，鼻纳气七息。除腹中弦切痛。
心脏是五脏的主宰，其正经（手少阴心经）不可受邪，如果正经受邪而疼痛，则早晨发病晚上就会死亡，晚上发病早晨就会死亡，来不及进行救治。所谓的久心痛，是因为心的分支络脉受到风、寒、热等邪气侵袭而产生的疼痛，所以虽然形成病症但不会致死，发作有定时，经久不愈。
心和小肠互为表里，都象征火，而火属于阳气。因为心是五脏的主宰，所以正经不受邪气侵犯。如果被邪气伤害而疼痛，就会导致死亡。如果是分支络脉被风邪侵袭而疼痛，则会经久形成病症。那种心中悬吊急迫、烦闷懊恼的疼痛，是因为邪气逼迫阳气，导致气机不能宣通畅达，壅滞瘀结而生热，所以心中像悬挂一样急迫，感到烦闷懊恼且疼痛。
心痛且多唾沫的，是因为水饮停聚侵袭了心的络脉。所谓停饮，是由水液代谢异常引起的。心气通达于舌，心与小肠相合，都象征火；小肠是心的腑，心之水气下行进入小肠，化为小便排出，那么心的络脉就不会有水饮停聚。膀胱与肾都象征水，膀胱是肾的腑，主要贮藏津液；肾的液上行表现为唾，肾气向下通达于前阴，如果脏腑功能平和，那么水液就能向下流动并通畅排泄；如果寒热邪气相互侵袭，导致脏腑不调，津液和水饮停积，向上逼迫心脏，使心气不能宣通畅达，所以出现疼痛且多唾的症状。
心痛且不能进食的，是因为积寒在内，客居于脾并侵袭心络所致。心属阳气；寒属阴气。寒气侵袭心脏，阴阳相互交争，冷热相互搏击，所以导致疼痛。脾主消化水谷，冷气客居其中，则脾气寒冷虚弱，无法胜任对水谷的运化。心属火，脾属土，这是母子关系，两者都被邪气侵袭，所以既疼痛又不能进食。
腹痛，是由于脏腑虚弱，寒冷之气客居于肠胃和募原之间，凝结聚集不散，正气与邪气相互交争搏击，所以产生疼痛。如果有阴气搏结于阴经，就会出现腹痛伴有肠鸣，这称为“寒中”。这是阳气不足、阴气有余的表现。诊察寸口脉象沉而紧，则是腹痛。尺脉紧，则是脐下疼痛。脉象沉迟，也是腹痛。脉象来势触触有力，则是少腹疼痛。脉象阴部弦紧，则是腹痛。凡是腹部紧急疼痛，这是里有病，脉象应当沉。如果脉象细弱却反而浮大，说明病情应当好转。如果病人没有立即好转，必定会死亡，因为病情与脉象相反的缘故。关于汤药、熨法、针刺、砭石的治疗，另有专门的方剂，补养和导引的方法，现在附在后面。
《养生方·导引法》说：治疗大腿、小腿、手臂疼痛的方法：弯曲一条腿和一只手臂中疼痛的部位，身体正面向上仰卧，闭住口鼻的气，如果是腹痛，用意念引导气息推向疼痛处，感到发热就好了。
又说：仰卧，伸展两条小腿和两只手，翘起脚趾，用鼻子吸气，尽力做到七次呼吸。可以消除腹中拘急切痛。
又说：正面向上仰卧，用口慢慢吸气，用鼻子呼气。可以消除里急后重。饱食之后吞咽气息数十次，可以使中焦温暖；如果吸入寒气，会导致干呕和腹痛。用口纳气七十次，可以振奋腹部；吞咽气息数十次，两手互相摩擦使其发热，然后用热手按摩腹部，使气下行。
又说：仰卧，两脚和两手向上仰，用鼻子吸气七次呼吸。可以消除腹中拘急切痛。
The Heart is the master of the five Zang organs. Its regular channel (Shou-Shao-Yin Xin-Jing, the Hand Shaoyin Heart Meridian) must not be injured. If injured and causing pain, death will occur in the morning if onset was in the evening, or in the evening if onset was in the morning, leaving no time for treatment. The so-called chronic heart pain (Jiu Xin Tong) arises when the branch collateral vessels of the Heart are invaded by Wind, Cold, or Heat pathogens, resulting in pain. Thus, although a condition forms, it is not fatal; it occurs at specific times and persists without healing.
The Heart and Small Intestine form an interior-exterior relationship, both symbolizing Fire, and Fire belongs to Yang Qi. Since the Heart is the master of the five Zang organs, its regular channel does not accept pathogenic invasion. If injured by pathogens and causing pain, death ensues. If the branch collateral vessels are invaded by Wind pathogens causing pain, it becomes a chronic condition. Pain characterized by a hanging, urgent sensation and vexation/irritability (Ao Nu) occurs because pathogens force upon Yang Qi, preventing the smooth flow and dissemination of Qi, leading to stagnation, stasis, and heat generation. Consequently, the Heart feels suspended and urgent, accompanied by vexation, irritability, and pain.
Heart pain accompanied by excessive salivation is caused by retained fluid (Ting Yin) invading the collaterals of the Heart. Retained fluid results from abnormalities in fluid metabolism. Heart Qi connects to the tongue; the Heart and Small Intestine are harmonized, both symbolizing Fire; the Small Intestine is the Fu organ of the Heart. Water-Qi from the Heart descends into the Small Intestine and transforms into urine, ensuring that no fluid remains stagnant in the Heart's collaterals. The Bladder and Kidney both symbolize Water; the Bladder is the Fu organ of the Kidney, primarily storing body fluids; the fluid of the Kidney ascends as saliva, and Kidney Qi descends to the genitalia. If the Fu and Zang organs are in harmony, fluids flow downward and discharge smoothly. If Cold and Heat pathogens invade each other, causing disharmony among the Fu and Zang organs, body fluids and water-drinkings accumulate and stagnate, pressing upward against the Heart, obstructing the smooth flow of Heart Qi, thus causing pain and excessive salivation.
Heart pain accompanied by inability to eat is caused by accumulated Cold residing internally, lodging in the Spleen and invading the Heart collaterals. The Heart represents Yang Qi; Cold represents Yin Qi. When Cold invades the Heart, Yin and Yang contend, and Cold and Heat clash, causing pain. The Spleen governs the digestion of food and fluids; when Cold lodges within, Spleen Qi becomes cold and weak, unable to handle food and fluids. The Heart is Fire, and the Spleen is Earth; they share a mother-son relationship. Both being invaded by pathogens causes pain and an inability to eat.
Abdominal pain (Fu Tong) arises from deficiency of the Fu and Zang organs, allowing Cold Qi to lodge between the intestines, stomach, and Mu Yuan (epigastric region/membranes), where it condenses and accumulates without dispersing. Righteous Qi and Pathogenic Qi contend and strike each other, causing pain. If Yin Qi contending with Yin meridians, abdominal pain accompanied by borborygmus (intestinal rumbling) occurs, termed "Cold Center" (Han Zhong). This indicates insufficient Yang Qi and excess Yin Qi. Palpating the Cun Kou pulse: if deep and tight, it indicates abdominal pain. If the Chi pulse is tight, there is pain below the umbilicus. A deep and slow pulse indicates abdominal pain. A pulse that feels "Chu Chu" (vibrant/tactile) indicates lower abdominal pain. A string-taut pulse in the Yin position indicates abdominal pain. Generally, acute abdominal pain indicates internal disease, and the pulse should be Deep (Chen). If the pulse is Fine (Xi) yet floating and large, recovery is expected. If the patient does not recover immediately, death is certain, because the disease presentation contradicts the pulse. Regarding decoctions, moxibustion/warming applications, acupuncture, and stone therapy, there are separate specific formulas. Nourishing and guiding exercises are attached hereafter.
The *Yang Sheng Fang* (Prescriptions for Health Preservation) · *Dao Yin Fa* (Guiding and Pulling Methods) states: To treat pain in the thighs, calves, arms, and hands: Flex one leg and arm where the pain is located. Lie supine on your back. Close the mouth and nose to hold the breath. For abdominal pain, use intention to push Qi towards the painful area; once heat is felt, it heals.
It also states: Lie supine, extend both legs and arms, point the toes upward, inhale through the nose, striving for seven breath cycles. This eliminates stringy and cutting pain in the abdomen.
It also states: Lie supine on your back, inhale slowly through the mouth, exhale through the nose. This eliminates internal urgency. After a full meal, swallow Qi dozens of times to warm the Middle Jiao; if Cold Qi is inhaled, it causes dry heaving and abdominal pain. Inhale Qi seventy times to vigorously stimulate the abdomen; swallow Qi dozens of times, rub hands together until hot, then massage the abdomen to guide Qi downward.
It also states: Lie supine, raise both feet and hands, inhale through the nose for seven breath cycles. This eliminates stringy and cutting pain in the abdomen.
