一人不病，忽一日满面黑色，自想气色黑者死，求医诊视。一医为诊脉无病，似为秽
气蓄于面部不散，故致黑色，曾有是否？患者曰∶果登厕被臭气隐忍良久，下厕遂有此。医
曰∶去恶臭无过至香，可用沉檀焚炉中，安帐内，患人以被围坐，勿令香气散出，瞑目端
坐，候香气尽，方可揭帐。根据其法行之，面色渐变，旬日如故。
一人年六十，身瘦弱，病头面不耐寒，气弱不敢当风行坐，诸药不效。医为诊脉皆弦
细而微，且其人年高，素食茶果，而阳明之经本虚。经云∶气不足，则身以前皆寒栗。此由
胃气虚，不上荣于头面，故恶风寒，先以附子理中汤温其中气，次以升麻加附子主之。

六节藏象论篇曰∶肾者，主蛰，封藏之本，精之处也，其华在发。
五脏生成篇曰∶肾之合骨也，其荣发也。多食甘，则骨痛而发落。（注云∶甘益脾，胜
于肾，肾不胜，故骨痛而发脱落。）
上古天真论曰∶女子一七岁肾气实，齿更发长。五七阳明脉衰，面始焦，发始堕。丈夫
八岁肾气实，发长齿更。五八肾气衰，发堕齿槁。
《巢氏病源》云∶足少阳胆之经，其荣在须。足少阴肾之精，其华在发。冲任之脉，为
十二经之海，谓之血海。其别络上唇口。若血盛，则荣于头发，故须发美。若血气衰弱，经脉
虚竭，不能荣润，故须发秃落。
《灵枢经》帝曰∶妇人无须者，无气血乎？岐伯曰∶冲脉、任脉，皆起于胞中，上循背
里，为经络之海。其浮而外者，循腹上行，会于咽喉，别络唇口。今妇人之生，有余于气，
不足于血，以其数脱血也。（女人月月而经通，故云数肿血。）冲任之脉，不荣口唇，故
须不生焉。又曰∶人有伤于阴，阴气绝而不起，阴不用，然其须不去。宦者独去，其故何也？
岐伯曰∶宦者去其宗筋，伤其冲脉，血泻不覆，皮肤内结，唇口不荣，故须不生。有人未
尝被伤，不脱于血，其须不生，何也？曰∶此天之所不足也，禀冲任不盛，宗筋不成，有
气无血，唇口不荣，故须不生。
有一位身体健康的人，忽然有一天满脸呈现黑色，他自己认为气色发黑是死亡的征兆，便求医生诊治。一位医生为他诊脉，发现并无疾病，推测可能是污秽之气积聚在面部未能消散，导致面色变黑，询问患者是否有过这种情况。患者回答说：确实有一次上厕所时，因忍受恶臭气味良久，从厕所出来后便出现了这种状况。医生说：去除恶臭没有比用极香的香料更好的方法了，可以使用沉香和檀香在炉中焚烧，安置在床帐内，让患者用被子围坐其中，不要让香气散失，闭目静坐，等到香气燃尽后，才可以揭开帐子。按照这个方法施行，患者的面色逐渐改变，十天后恢复了正常。
另一位六十岁的老人，身体瘦弱，病症表现为头面部不耐受寒冷，气息虚弱不敢迎着风坐着或行走，服用各种药物均无效。医生为他诊脉，脉象皆弦细而微弱，且此人年事已高，平时素食、喝茶吃水果，导致阳明经（足阳明胃经）原本就虚弱。医经中说：气不足，则身体前部都会感到寒冷战栗。这是由于胃气虚弱，不能向上滋养头面，所以厌恶风寒。先用附子理中汤温补中焦之气，再用升麻加附子方主治。

《素问·六节藏象论篇》说：肾，主蛰伏，是封藏的根本，是精气的所在，其荣华表现在头发上。
《素问·五脏生成篇》说：肾与骨相合，其荣华表现在头发上。多吃甘味食物，会导致骨头疼痛而头发脱落。（注释说：甘味益脾，克制肾，肾不胜克，所以骨头疼痛而头发脱落。）
《素问·上古天真论》说：女子七岁，肾气充实，换牙头发生长。三十五岁（五七），阳明脉衰退，面部开始憔悴，头发开始脱落。男子八岁，肾气充实，头发生长换牙。四十岁（五八），肾气衰退，头发脱落牙齿枯槁。
《诸病源候论》说：足少阳胆经，其荣华表现在胡须上。足少阴肾的精气，其荣华表现在头发上。冲脉和任脉，是十二经脉的海，称为血海。它们的别络上行至唇口。如果血液旺盛，就能滋养头发，所以胡须和头发美观。如果气血衰弱，经脉虚竭，不能滋养润泽，所以胡须和头发秃落。
《灵枢经》黄帝问：妇女没有胡须，是因为没有气血吗？岐伯回答：冲脉、任脉，都起于胞宫，向上沿着背部里面行走，成为经络的海。其中浮行于体表的，沿着腹部上行，会合于咽喉，别出的络脉联系唇口。现在妇女的生理特点，气有余而血不足，因为经常失血。（女人每月月经通畅，所以说经常失血。）冲任二脉，不能滋养口唇，所以胡须不生。又说：有人损伤了阴器，阴气断绝而不能勃起，阴器失去功能，但是胡须并不脱落。宦官只有胡须脱去，这是什么原因呢？岐伯说：宦官割去了宗筋，损伤了冲脉，血液泻出不能恢复，皮肤内部结聚，唇口得不到滋养，所以胡须不生。有人未曾被伤害，也没有失血，为什么胡须不生呢？回答说：这是先天禀赋不足，冲任二脉不旺盛，宗筋不成形，有气无血，唇口得不到滋养，所以胡须不生。
A person who was previously healthy suddenly developed a black complexion on his entire face. Believing that a black facial color indicated death, he sought medical attention. A physician palpated his pulse and found no disease, speculating that foul qi might have accumulated in the face and failed to dissipate, causing the blackness, and asked if such an event had occurred. The patient replied: Indeed, while using the toilet, I endured a foul odor for a long time, and this condition appeared after leaving the latrine. The physician said: To eliminate foul odors, nothing is superior to highly fragrant substances. One may burn agarwood (Chenxiang) and sandalwood (Tantan) in a censer, place it inside a bed canopy, and have the patient sit surrounded by quilts within the canopy, ensuring the fragrance does not escape. The patient should close his eyes and sit quietly until the fragrance burns out, then remove the canopy. Following this method, the patient's complexion gradually improved, and after ten days, it returned to normal.
Another patient, aged sixty, was emaciated and weak. His symptoms included intolerance of cold in the head and face, and weak qi preventing him from sitting or walking facing the wind. Various medicines proved ineffective. The physician palpated his pulse, finding them wiry, thin, and faint. Given his advanced age and habit of consuming a vegetarian diet with tea and fruits, the Yangming channel (Stomach Channel of Foot-Yangming) was inherently deficient. The classics state: "When qi is insufficient, the anterior part of the body feels cold and shivering." This resulted from deficiency of Stomach qi, which failed to ascend and nourish the head and face, leading to aversion to wind and cold. Initially, Fuzi Lizhong Tang (Aconite Decoction to Regulate the Middle) was used to warm the middle jiao qi, followed by Shengma Jia Fuzi Fang (Cimicifuga Formula with Aconite).
Xian Gu (ST43): Treats facial swelling and eye abscesses; acupuncture with bleeding leads to immediate cure.
Jia Che (ST6): Treats cheek swelling, oral tightness, pain at Jia Che, and inability to chew; both acupuncture and moxibustion are applicable.
He Gu (LI4), Lie Que (LU7), Di Cang (ST4): Treats facial and mandibular swelling and sores.
Select the Stomach Channel: First, the Foot-Yangming Stomach Channel, when disturbed, causes aversion to cold and darkening of the face.
Select the Kidney Channel: Second, the Foot-Shaoyin Kidney Channel, when disturbed, causes hunger without desire to eat, and a face as black as lacquered wood; select points based on excess/deficiency and cold/heat patterns.
Shaoyin Collateral: Treats black complexion, teeth appearing long with dirt, abdominal distension, and constipation.
Taiyang Collateral.
Taiyin Collateral: Treats abdominal distension, constipation, and dyspnea; frequent belching and vomiting lead to a red face, while absence of vomiting leads to a black face.
The *Suwen: Liujie Zangxiang Lun* states: The Kidney governs hibernation, is the root of sealing and storing, the residence of essence, and its luster manifests in the hair.
The *Suwen: Wuzang Shengcheng Lun* states: The Kidney corresponds to bone, and its luster manifests in the hair. Excessive consumption of sweet flavors causes bone pain and hair loss. (Note: Sweet flavor benefits the Spleen and overcomes the Kidney; when the Kidney cannot withstand this overcoming, bone pain and hair loss occur.)
The *Suwen: Shanggu Tianzhen Lun* states: At seven years old, a girl's Kidney qi becomes substantial, her teeth change, and her hair grows. At thirty-five (five sevens), the Yangming pulse declines, her face begins to wither, and her hair starts to fall. At eight years old, a boy's Kidney qi becomes substantial, his hair grows, and his teeth change. At forty (five eights), his Kidney qi declines, his hair falls, and his teeth become brittle.
The *Chushi Bingyuan* states: The Foot-Shaoyang Gallbladder Channel has its luster in the beard. The essence of the Foot-Shaoyin Kidney has its luster in the hair. The Chong and Ren vessels are the seas of the twelve channels, known as the Sea of Blood. Their collateral branches ascend to the lips and mouth. If blood is abundant, it nourishes the hair, resulting in beautiful beard and hair. If qi and blood are weak, and the channels are empty and exhausted, they fail to nourish and moisten, resulting in baldness and hair loss.
In the *Lingjing*, the Emperor asked: Do women without beards lack qi and blood? Qibo answered: The Chong and Ren vessels both originate in the uterus, ascend along the interior of the back, and serve as the sea of the collaterals. Those floating externally ascend along the abdomen, meet at the throat, and their collateral branches connect to the lips and mouth. In women, there is surplus qi but deficient blood due to frequent blood loss. (Women menstruate monthly, hence the term "frequent blood loss.") Since the Chong and Ren vessels do not nourish the lips and mouth, beards do not grow. He further stated: Some individuals injure their yin organs, causing yin qi to cease rising and function, yet their beards do not fall off. Eunuchs lose only their beards; why is this? Qibo said: Eunuchs have their Zongjin (genitals) removed, injuring the Chong vessel; blood is lost and not restored, internal skin binding occurs, and the lips and mouth are not nourished, so beards do not grow. What about those who have never been injured nor lost blood, yet do not grow beards? The answer is: This is a congenital insufficiency; the Chong and Ren vessels are not vigorous, the Zongjin does not form properly, there is qi but no blood, the lips and mouth are not nourished, so beards do not grow.
