凡患耳中策策痛者，皆是风入于肾之经也。不治，流入肾，则卒然变脊强背直成痉也。
若因痛而肿，生痈疖，脓溃邪气歇，则不成痉。所以然者，足少阴为肾之经，宗脉之所聚，
其气通于耳。上焦有风邪，入于头脑，流至耳内，与气相击，故耳中痛。耳为肾候，其气相
通，肾候腰脊，主骨髓，故邪流入肾，脊强背直。
耳耵聍者，耳里津液结聚所成。人耳皆有之，轻者不能为患；若加以风热乘之，则结硬
成丸核塞耳，亦令耳暴聋。
足少阴为肾之经，其气通于耳。其经虚，风热乘之，随脉入于耳，与血气相搏，故耳生
牙齿痛者，是牙齿相引痛。牙齿是骨之所终，髓之所养。手阳明之支脉，入于齿。若髓
气不足，阳明脉虚，不能荣于牙齿，为风冷所伤，故疼痛也。又有虫食于牙齿，则齿根有孔
，虫居其间，又传受余齿，亦绵疼痛。此则针灸不瘥，敷药虫死，乃痛止。
牙齿皆是骨之所终，髓气所养，而手阳明支脉入于齿。脉虚髓气不足，风冷伤之，故疼
痛也。又虫食于齿，则根有孔，虫于其间，又传受余齿，亦痛掣难忍。若虫痛，非针灸可瘥
，敷药虫死，乃痛止。
手阳明之支脉入于齿，齿是骨所终，髓之所养。若风冷客于经络，伤髓冷气入
齿根，则齿痛。若虫食齿而痛者，齿根有孔，虫在其间，此则针灸不瘥，敷药虫死，痛乃止
。其汤熨针石，别有正方。补养宣导，今附于后。
《养生方》云∶常向本命日，栉发之始，叩齿九通，阴咒曰∶太帝散灵，五老反
真；泥丸玄华，保精长存；左拘隐月，右引根；六合清练，百神受恩。咒毕，咽唾
三过。常数行这，使齿不痛，发牢不白，头脑不痛。
《养生方·导引法》云∶东向坐，不息四通，琢齿二七。治齿痛病。大张口，琢齿二七
，一通二七。又解，四通中间，其二七大势，以意消息，瘥病而已，不复疼痛。解病，鲜白
不梨，亦不疏离。久行不已，能破金刚。
又云∶东向坐，不息四通，上下琢齿三十六下。治齿痛。
凡是患耳中像针刺一样疼痛的，都是风邪侵入足少阴肾经所致。如果不治疗，病邪流入肾脏，就会突然变成脊柱僵硬、背部挺直而发展为痉病（以项背强直、角弓反张为特征的病证）。
如果因为疼痛而导致肿胀，生出痈疖，脓液溃破后邪气消散，就不会形成痉病。之所以这样，是因为足少阴经是肾的经脉，是众多经脉汇聚的地方，其气与耳相通。上焦有风邪，侵入头脑，流至耳内，与正气相搏击，所以耳中疼痛。耳是肾的外候，二者气机相通，肾主腰脊和骨髓，所以邪气流入肾脏，会导致脊柱僵硬、背部挺直。
耳垢（耵聍），是由耳内的津液凝结而成的。人的耳朵里都有，轻微的不会造成危害；如果再加上风热之邪侵袭，就会凝结变硬，形成丸状核堵塞耳道，也会导致突发性耳聋。
足少阴经是肾的经脉，其气与耳相通。如果这条经脉虚弱，风热之邪乘虚而入，随着脉道进入耳内，与血气相互搏结，所以耳部生病。
牙齿疼痛，是指牙齿之间相互牵引产生的疼痛。牙齿是骨骼的末端，由髓气滋养。手阳明大肠经的支脉，进入牙齿。如果髓气不足，阳明脉虚弱，不能濡养牙齿，被风冷之邪所伤，所以产生疼痛。又有因虫蛀蚀牙齿，导致齿根出现孔洞，虫子居住在孔洞中，又传染给其他牙齿，也会引起连绵不断的疼痛。这种情况针灸无法治愈，只有敷药使虫子死亡，疼痛才会停止。
牙齿都是骨骼的末端，由髓气滋养，手阳明大肠经的支脉进入牙齿。如果脉象虚弱、髓气不足，被风冷之邪伤害，所以产生疼痛。又有因虫蛀蚀牙齿，导致齿根出现孔洞，虫子在孔洞中，又传染给其他牙齿，也会引起剧烈难忍的牵拉性疼痛。如果是虫牙疼痛，针灸无法治愈，只有敷药使虫子死亡，疼痛才会停止。
手阳明大肠经的支脉进入牙齿，牙齿是骨骼的末端，由髓气滋养。如果风冷之邪客居于经络，寒气损伤髓气并进入齿根，就会导致牙齿疼痛。如果是虫蛀导致的牙齿疼痛，齿根会有孔洞，虫子在其中，这种情况针灸无法治愈，只有敷药使虫子死亡，疼痛才会停止。至于汤药外熨、针刺砭石等疗法，另有专门的方剂。补益调养和导引宣通的方法，现在附在后面。
《养生方》说：经常在属自己本命的日子，开始梳头时，叩击牙齿九次，心中默念咒语说：“太帝散灵，五老返真；泥丸玄华，保精长存；左拘隐月，右引根；六合清练，百神受恩。”咒语念完后，吞咽唾液三次。经常这样做，可以使牙齿不痛，头发牢固不白，头脑不痛。
《养生方·导引法》说：面向东方坐定，闭息四次，咀嚼牙齿十四次（二七）。用于治疗牙齿疼痛。张大嘴巴，咀嚼牙齿十四次，算作一次，共做两次。另一种解释是，在闭息的四个阶段中间，进行十四次的动作，用意念来调节呼吸和动作，疾病就会痊愈，不再疼痛。病愈后，牙齿新鲜洁白不脱落，也不稀疏松动。长期练习不停止，能破除金刚般的坚固（指身体强健或意志坚定）。
又说：面向东方坐定，闭息四次，上下咀嚼牙齿三十六次。用于治疗牙齿疼痛。
Whenever one suffers from a stabbing pain in the ear, it is all due to Wind pathogen invading the Foot-Shaoyin Kidney Meridian (Kidney Channel of Foot-Shaoyin). If left untreated, the pathogen flows into the Kidney, suddenly causing stiffness of the spine and straightening of the back, developing into Jing Disease (spasm disease characterized by neck and back rigidity and opisthotonos).
If swelling occurs due to the pain, leading to the formation of carbuncles or furuncles, and the pus breaks out with the dissipation of the pathogenic factor, Jing Disease will not develop. The reason for this is that the Foot-Shaoyin Meridian is the channel of the Kidney, where numerous vessels converge, and its Qi connects with the ear. When Wind-Evil resides in the Upper Jiao, it enters the head and brain, flows into the ear, and clashes with the body's Qi, causing pain in the ear. Since the ear is the external manifestation of the Kidney, their Qi is interconnected; as the Kidney governs the waist and spine and dominates bone marrow, when the pathogen flows into the Kidney, it results in spinal stiffness and back straightening.
Earwax (Cerumen) is formed by the condensation of fluids in the ear. Everyone has it; mild cases do not cause harm. However, if invaded by Wind-Heat, it hardens into nodules that block the ear canal, also causing sudden deafness.
The Foot-Shaoyin Meridian is the channel of the Kidney, and its Qi connects with the ear. If this meridian is deficient, Wind-Heat takes advantage of the deficiency, entering the ear along the vessels and clashing with Blood and Qi, thus causing ear diseases.
Toothache refers to pain radiating between the teeth. Teeth are the extremities of bones, nourished by Marrow-Qi. The branch of the Hand-Yangming Large Intestine Meridian enters the teeth. If Marrow-Qi is insufficient and the Yangming pulse is weak, failing to nourish the teeth, they become injured by Cold-Wind, resulting in pain. Additionally, if worms eat away at the teeth, holes form at the tooth roots where the worms reside, spreading to other teeth and causing continuous pain. In such cases, acupuncture and moxibustion are ineffective; only applying topical medication to kill the worms will stop the pain.
Teeth are the extremities of bones, nourished by Marrow-Qi, and the branch of the Hand-Yangming Large Intestine Meridian enters them. If the pulse is weak and Marrow-Qi is insufficient, injury by Cold-Wind causes pain. Furthermore, if worms erode the teeth, holes form at the roots where the worms reside, spreading to other teeth and causing unbearable pulling pain. For worm-induced toothache, acupuncture and moxibustion cannot cure it; only applying topical medication to kill the worms stops the pain.
The branch of the Hand-Yangming Large Intestine Meridian enters the teeth, which are the extremities of bones nourished by Marrow-Qi. If Cold-Wind lodges in the meridians, damaging the Marrow and allowing Cold Qi to enter the tooth roots, toothache occurs. If the pain is caused by worms, holes appear at the roots where the worms reside; acupuncture and moxibustion are ineffective here, and only killing the worms with topical medication stops the pain. Regarding decoctions, hot compresses, acupuncture, and stone needles, there are separate specific formulas. Methods of tonification, nourishment, and guidance are attached below.
The *Yangsheng Fang* (Prescriptions for Nourishing Life) states: On days corresponding to one's birth year branch, at the beginning of combing hair, tap the teeth nine times while silently reciting the incantation: "Tai Di scatters spiritual energy, Wu Lao returns to truth; Niwan Xuan Hua preserves essence for long life; Left Ju hides the moon, Right Yin draws the root; Liu He is pure and refined, Bai Shen receives grace." After the incantation, swallow saliva three times. Practicing this regularly prevents toothache, keeps hair firm and white-free, and prevents headache.
The *Yangsheng Fang · Daoyin Fa* (Guidance and Pulling Method) states: Sit facing East, hold breath four times, and grind the teeth fourteen times (two sevens). This treats toothache. Open the mouth wide, grind the teeth fourteen times, counting this as one cycle, repeated twice. Another interpretation suggests that during the four breath-holding intervals, perform the fourteen grinding movements, regulating intent and respiration, so that the illness heals and pain ceases. Upon recovery, teeth remain fresh, white, intact, and not loose. Long-term practice without cessation can break through diamond-like hardness (symbolizing extreme resilience or strength).
It also states: Sit facing East, hold breath four times, and grind the teeth up and down thirty-six times. This treats toothache.
