肉，足阳明气发，禁不可灸，又不言得针，此要禁为第一部，故生痈疽者死也。）腓二，腓者
也；（腓音肥。承筋一名 肠，一名直肠，脉在 中央陷中，足阳明太阳气所发，禁不可刺，故
为要害之处，生痈疽者死也。平按∶《甲乙》腓作 ，无腓者 也四字。《灵枢》 也作 也。）
背三；（自要输以上二十一椎两箱称背，去脏腑甚近，皮肉至薄，若生痈疽，陷而必死也。）五
脏之输四；（五脏手足二十五输，当于输穴生痈疽者死也。）项五，（项之前曰颈，后曰项，三阳
督脉在项，故项生痈疽致死也。）五部有痈疽者死。（痈疽害甚，故生人之要处致死。）病始手
臂者，先取手阳明、太阴而汗出；（以下言疗热病取脉先后。热病等所起，起于四肢及头，故病
起两手者，可取手阳明井商阳，在手大指次指内侧，去爪甲角如韭叶，以手阳明谷气盛也；及手太
阴孔最，在腕上七寸也。）病始头首者，先取项太阳而汗出；（有热等病起于头者，可取于项
足太阳脉天柱之穴，天柱在挟项后发际大筋外陷也。）病始足 者，先取足阳明而汗出。（病起
足者，可取阳明合三里穴，三里在膝下三寸 外廉。平按∶《灵枢》、《甲乙》 作胫。）臂太
阴可出汗，（手太阴脉主气，故出汗取之也。平按∶出汗《灵枢》作汗出，下同。）足阳明可出
汗。（足阳明主水谷，多气血，故出汗取之。）取阴而汗出甚者，止之于阳；取阳而汗出甚者，
止之于阴。（取阴脉出汗不止，可取阳脉所主之穴止；若取阳脉出汗不止，可取阴脉所主之穴止
之也。平按∶《甲乙》无两于字。）凡刺之害，中而不去则精泄，不中而去则致气；精泄则病甚
而，致气则生为痈疡。（凡行针要害，无过二种∶一种者，刺中于病补泻不以时去针，则泄人
精气；刺之不中于病，即便去针，以伤良肉，故致气聚。精泄益虚，故病甚虚 。 ，怯也。气聚不散，为痈为疡也。）
肌肉部位，是足阳明经气发出的地方，禁止施灸，也不宜针刺，这是首要禁忌的第一条，因此如果在此处发生痈疽，患者就会死亡。）小腿肚腓肠肌部位，二是；（“腓”音同“肥”。承筋穴又名肠中穴，又名直肠穴，经脉位于穴位中央的凹陷处，是足阳明、足太阳经气所发之处，禁止针刺，所以这里是要害所在，若生痈疽则致死。平按：《甲乙经》中“腓”写作“”，没有“腓者 也”这四个字。《灵枢》中“ 也”写作“ 也”。）背部第三处；（从腰部的腧穴以上共二十一节脊椎，两侧称为背，此处距离脏腑非常近，皮肤肌肉极薄，如果发生痈疽，溃烂深陷必然导致死亡。）五脏的腧穴第四处；（手足三阴三阳经在五脏对应的二十五处腧穴，如果在这些腧穴上发生痈疽，患者就会死亡。）颈部第五处，（颈的前部叫“颈”，后部叫“项”，三阳经和督脉都在项部经过，所以在项部发生痈疽会导致死亡。）这五个部位如果有痈疽，患者都会死亡。（痈疽危害严重，发生在维持生命的关键部位就会导致死亡。）疾病起始于手臂的，先取手阳明经、手太阴经使汗出；（以下论述治疗热病时选取经脉的先后顺序。热病等病症，多起于四肢及头部，所以疾病起始于双手的，可以选取手阳明经的井穴商阳穴，该穴在手大指与次指之间内侧，距离爪甲角如韭菜叶宽度处，因为手阳明经谷气旺盛；以及手太阴经的郄穴孔最穴，位于腕横纹上七寸处。）疾病起始于头部的，先取项部的足太阳经使汗出；（有热病等起于头部的，可以选取项部足太阳经的天柱穴，天柱穴位于挟持项部后方发际线的大筋外侧凹陷处。）疾病起始于足部的，先取足阳明经使汗出。（疾病起于足部的，可以选取足阳明经的合穴足三里穴，足三里穴位于膝眼下三寸胫骨外侧。平按：《灵枢》、《甲乙经》中“ ”写作“胫”。）手太阴经可以使其出汗，（手太阴经主司气，所以通过取此经穴来发汗。平按：《灵枢》中“出汗”写作“汗出”，下同。）足阳明经可以使其出汗。（足阳明经主司水谷精微，气血充盛，所以通过取此经穴来发汗。）如果刺阴经而汗出过多的，就在阳经止之；如果刺阳经而汗出过多的，就在阴经止之。（如果刺阴脉导致出汗不止，可以选取阳脉所主的穴位来制止；如果刺阳脉导致出汗不止，可以选取阴脉所主的穴位来制止它。平按：《甲乙经》中没有两个“于”字。）凡是针刺的危害，如果刺中病所却未及时去针，就会耗泄精气；如果没有刺中病所就急于去针，就会导致邪气滞留；精气耗泄则病情加重并出现怯弱症状，邪气滞留则会形成痈疡。（凡施行针刺的要害，不过两种情况：一种情况是，针刺虽中病所但补泻不当且不及时去针，就会泄掉人的精气；另一种情况是，针刺未中病所就立即去针，从而损伤好肉，导致邪气聚集。精气耗泄更加虚弱，所以病情加重且身体怯弱。 ，意为怯弱。邪气聚集不散，就会形成痈或疡。）
The flesh area is where the Qi of the Foot-Yangming channel originates; moxibustion is strictly prohibited, and needling is also not advised. This constitutes the first primary prohibition; therefore, if a carbuncle or ulcer (Yongju) develops here, it is fatal.) The calf muscle area, secondly; ("Fei" sounds like "fei". Chengjin acupoint is also known as Changzhong or Zhichang. The vessel lies in the central depression of this point, where the Qi of the Foot-Yangming and Foot-Taiyang channels originate. Needling is prohibited here, making it a critical area; if a carbuncle or ulcer develops, it is fatal. Ping An: In *Jia Yi Jing*, "Fei" is written as " ", and the four characters "Fei zhe ye" are absent. In *Ling Shu*, " ye" is written as " ye".) The back, thirdly; (From the Shu points at the waist upwards, there are twenty-one vertebrae on both sides called the back. This area is very close to the Zang-Fu organs, with extremely thin skin and flesh. If a carbuncle or ulcer develops and becomes sunken, death is inevitable.) The Shu points of the Five Zang organs, fourthly; (There are twenty-five Shu points corresponding to the Five Zang organs across the Hand and Foot Yin and Yang channels. If a carbuncle or ulcer develops at these Shu points, it is fatal.) The neck region, fifthly; (The anterior part of the neck is called "Jing", and the posterior part is called "Xiang". The Three Yang channels and the Du vessel traverse the Xiang. Therefore, if a carbuncle or ulcer develops in the Xiang, it leads to death.) If a carbuncle or ulcer develops in any of these five areas, it is fatal. (Carbuncles and ulcers cause severe harm; developing in vital areas for sustaining life leads to death.) When the disease begins in the arm, first select the Hand-Yangming and Hand-Taiyin channels to induce sweating; (The following discusses the sequence of selecting vessels for treating febrile diseases. Febrile diseases typically originate in the limbs and head. Thus, when the disease starts in both hands, one may select Shangyang (Jing-Well point of Hand-Yangming), located medially between the thumb and index finger, about the width of a leek leaf from the nail corner, because the Gu Qi of the Hand-Yangming channel is abundant; and Kongzui (Xi-Cleft point of Hand-Taiyin), located seven cun above the wrist crease.) When the disease begins in the head, first select the Foot-Taiyang channel at the neck to induce sweating; (For febrile diseases originating in the head, one may select Tianzhu (Foot-Taiyang) at the neck. Tianzhu is located in the depression lateral to the large tendons behind the hairline at the nape.) When the disease begins in the foot, first select the Foot-Yangming channel to induce sweating. (When the disease starts in the foot, one may select Zusanli (He-Sea point of Foot-Yangming), located three cun below the knee on the lateral aspect of the tibia. Ping An: In *Ling Shu* and *Jia Yi Jing*, " " is written as "Ting".) The Hand-Taiyin channel can be used to induce sweating, (The Hand-Taiyin channel governs Qi, so selecting its points induces sweating. Ping An: In *Ling Shu*, "Chu Han" is written as "Han Chu", same below.) The Foot-Yangming channel can be used to induce sweating. (The Foot-Yangming channel governs water and grain, possessing abundant Qi and Blood, so selecting its points induces sweating.) If excessive sweating occurs after needling Yin channels, stop it by selecting Yang channels; if excessive sweating occurs after needling Yang channels, stop it by selecting Yin channels. (If needling Yin vessels causes unceasing sweating, select points governed by Yang vessels to stop it; if needling Yang vessels causes unceasing sweating, select points governed by Yin vessels to stop it. Ping An: In *Jia Yi Jing*, the two instances of "Yu" are absent.) The harm of needling lies in two aspects: if the needle hits the target but is retained too long, essence and Qi will be depleted; if the needle misses the target and is withdrawn quickly, pathogenic Qi will accumulate. Depletion of essence leads to worsening disease and timidity; accumulation of Qi leads to the formation of carbuncles and ulcers. (The critical dangers of acupuncture are limited to two types: First, if the needle strikes the disease site but manipulation (tonification/reduction) is inappropriate and the needle is not removed promptly, human essence and Qi are drained. Second, if the needle does not strike the disease site and is immediately withdrawn, healthy flesh is injured, causing pathogenic Qi to gather. Depleted essence increases deficiency, leading to severe illness and timidity. , means timidity. Accumulated Qi that does not disperse forms carbuncles or ulcers.)
