目者，心之所使，神所寓焉。凡初热而目倦不开者，是将放标也。目中汪汪，若水
者，麻疹也。赤色者，热甚也。连 之肝风也。直视者，肝热也。发搐目窜者，风火
相搏也。痘未成脓而肿消目开者，毒反内攻也。收靥已后而目闭不开者，毒滞心肾也。
收靥不齐而跟生翳障者，毒流于目也。靥后而直视不转者，肾绝也。上窜者，心绝也。
非泣而泪自出者，肝绝也。微瞑者，气脱也。血贯瞳子者，火胜水竭也。及诸病闭目
摇头者，此阳脉不治，谓之心绝，并为不治。
颈项者，生气之本也。《经》曰∶天气通于肺，地气通于嗌，天食人以五气，喉
者，气之所由也，故喉主天气。更地食人以五味，咽者，味之所由也。故咽主地气。是
以颈项者，乃肝之俞，又咽喉之管束，阴阳之道路也。三阳之脉，自颈而上，三阴之
脉，自颈而远，故痘疮之候，颈项欲疏。若缠项而稠密太甚者，谓之锁项，则废其管
束，阻其道路，上不得降，下不得升，内者不出，外者不入。《经》曰∶出入废，则神
机化灭，升降息，则气立孤危。并病深而项软者，骨败也，并死不治。
《经》曰∶刺胸腹者，必避五脏，胸腹者，脏腑之郭也。又曰∶膈盲之上，中有父
母，盖指心肺也，即所谓称三仓之部位，故痘疮轻者，则胸前全无。若胸腹太重者，必
凶也。并病深而噪急，胸骨扇动者，是肺焦胀也。其左乳下动脉突出者，是宗脉绝也。
并为不治。
眼睛，是心神所驱使的，也是神气寄居的地方。凡是刚开始发热而眼睛疲倦睁不开的，这是痘疹将要发出的征兆。眼中水汪汪的，像有水一样，这是麻疹的表现。眼睛发红，说明热邪很盛。眼睛连眨（或斜视），是肝风内动的表现。眼睛直视不动，是肝热的表现。发生抽搐且眼球上窜，是风火相互搏结的表现。痘疹尚未化脓但肿胀消退、眼睛睁开，这是毒邪反而向内攻陷的表现。痘疹收靥之后却眼睛紧闭睁不开，这是毒邪滞留于心肾的表现。痘疹收靥不齐且眼尾生出翳障，这是毒邪流注于眼睛的表现。收靥之后如果眼睛直视不转动，这是肾气绝的表现。眼球向上窜动，这是心气绝的表现。不是哭泣却眼泪自行流出，这是肝气绝的表现。眼睛微微闭合，这是气虚外脱的表现。血液布满瞳孔，这是火邪亢盛而肾水枯竭的表现。以及各种疾病中闭目摇头的，这是阳脉无法治理，称为心绝，都属于不治之症。
颈项，是生气根本所在。《黄帝内经》说：天气通于肺，地气通于咽喉，天通过五气供养人，喉是气出入的通道，所以喉主管天气。又通过五味供养人，咽是味出入的通道，所以咽主管地气。因此，颈项是肝脏的俞穴所在，又是咽喉的管束之处，是阴阳之气运行的道路。三阳经脉，从颈部向上行；三阴经脉，从颈部向远处行。所以痘疹的征候中，颈项部的皮疹应当稀疏。如果颈项部皮疹缠绕且稠密太甚的，叫做“锁项”，这会废弛其管束功能，阻碍其道路，导致气机上面不能下降，下面不能上升，内部的邪气出不来，外部的正气进不去。《黄帝内经》说：出入的功能废弃，那么神机的变化就会灭息；升降的功能停止，那么气立的根基就会孤立危险。并且病情深重而颈项软弱的，是骨骼败坏的表现，并且属于死证，无法治疗。
《黄帝内经》说：针刺胸腹时，必须避开五脏，胸腹是脏腑的外郭。又说：膈肓之上，中有父母，这里指的是心和肺，也就是所谓的“三仓”部位。所以痘疹轻症的，胸前完全没有皮疹。如果胸腹部皮疹太重，必定是凶险之兆。并且病情深重而躁扰急促，胸骨扇动的，这是肺焦胀的表现。左侧乳下动脉突出的，这是宗脉绝断的表现。都属于不治之症。
The eyes are the instruments of the Heart-Shen (Spirit) and the abode where Shen resides. When fever first appears and the eyes are weary and unable to open, this indicates that the rash is about to erupt. If the eyes appear watery, as if filled with water, it signifies measles (Ma Zhen). Redness of the eyes indicates excessive heat. Frequent blinking or squinting indicates Liver Wind stirring internally. Fixed staring indicates Liver Heat. Convulsions accompanied by upward deviation of the eyes indicate a struggle between Wind and Fire. If the pustules have not yet formed pus but the swelling subsides and the eyes open, it indicates that the toxin has turned inward to attack the interior. If the eyes remain closed and cannot open after the scabs have fallen off, it indicates that the toxin is stagnant in the Heart and Kidney. If the scabs fall off unevenly and opacities form at the corners of the eyes, it indicates that the toxin has flowed into the eyes. If the eyes stare fixedly without rotation after the scabs have fallen off, it indicates the exhaustion of Kidney Qi. Upward deviation of the eyes indicates the exhaustion of Heart Qi. Tears flowing spontaneously without crying indicate the exhaustion of Liver Qi. Slight closing of the eyes indicates the depletion of Qi. Blood vessels filling the pupil indicates that Fire is excessive while Water (Kidney Yin) is exhausted. In various diseases, if the patient closes their eyes and shakes their head, this indicates that the Yang meridians cannot be regulated, termed "Heart Exhaustion," and all such cases are untreatable.
The neck and nape are the root of vital energy (Sheng Qi). The Classic states: "Heavenly Qi connects with the Lungs; Earthly Qi connects with the throat." Heaven nourishes humans with the Five Qi; the larynx (Hou) is the passage for Qi, thus the larynx governs Heavenly Qi. Earth nourishes humans with the Five Flavors; the pharynx (Yan) is the passage for flavors, thus the pharynx governs Earthly Qi. Therefore, the neck and nape are the Shu points of the Liver, the constriction of the throat, and the pathway for Yin and Yang. The Three Yang meridians ascend from the neck; the Three Yin meridians descend away from the neck. Thus, in the manifestations of smallpox/rash diseases, the rash on the neck should be sparse. If the rash on the neck is entangled and excessively dense, it is called "Locking the Neck" (Suo Xiang). This disables its constricting function and blocks its pathway, preventing Qi from descending above and ascending below, trapping internal pathogens and excluding external healthy Qi. The Classic states: "If entry and exit cease, the Spirit mechanism perishes; if ascent and descent stop, the Qi foundation stands alone in danger." Furthermore, if the disease is deep-seated and the neck becomes flaccid, it indicates bone failure, which is a death sentence and untreatable.
The Classic states: "When needling the chest and abdomen, one must avoid the five Zang organs. The chest and abdomen are the outer walls of the Zang organs." It also states: "Above the diaphragm and blind area, there are Father and Mother," referring here to the Heart and Lung, which correspond to the location known as the "Three Granaries." Therefore, in mild cases of rash diseases, there are no rashes on the chest. If the rashes on the chest and abdomen are too heavy, it is definitely a ominous sign. Furthermore, if the disease is deep-seated with restlessness and urgency, and the sternum moves like a fan, this indicates scorched and distended Lungs. If the arterial pulse under the left breast protrudes, this indicates the exhaustion of the Zong Mai (Gathering Vessel). Both conditions are untreatable.
