额心颏肾鼻脾部，左颊肝位右肺方，周身分主面属胃，头背膀胱腰肾疆，心肺胸膈
肝胆胁，腹肢属脾大小肠，包络之络联脏腑，三焦之气应无方。
【注】小儿出痘，自头面以及周身，各有脏腑所属部位，治者须详察部位以定吉凶。如
额先见点者，是毒发于心也；颏先见点者，毒发于肾也；左颊先见点者，毒发于肝也；右
颊先见点者，毒发于肺也；鼻先见点者，毒发于脾也。面属胃经部位也，头背属膀胱经
部位也，腰属肾经部位也，胸膈属心、肺二经部位也，胁旁属肝、胆二经部位也，肚腹
四肢属脾、大小肠三经部位也。至于包络，乃周身脂膜之络，联属百骸脏腑者也。三焦为
周身水精之气，充满躯壳脏腑者也。凡周身发痘，俱从此出，故无一定部位也。
痘形见点喜尖圆，恶隐蚊迹痱粟蚕，起胀渐绽充肥顺，顶平不突板实难。生浆敛束
形完固，软嫩皮薄痒塌缠，结痂如螺先后落，
最忌麸薄溃烂粘。
【注】痘形，气之为也。气胜毒，则毒为气驭，其毒解矣，故顺也；毒胜气，则气为
毒蚀，其气竭矣，故逆也。气毒相平，则势界于险，惟在医者调治得宜，使险变顺也。如
始出之形，顶尖而根圆，此气胜毒，为顺也；若隐如蚊咬，或如热痱，寒粟蚕种，此毒胜
气，为逆也。起胀之形，渐绽充肥，此气胜毒，为顺也；若顶平不突，板实不绽，此毒
胜气，为逆也。成浆之形，根红敛束，痘壳完固，此气胜毒，为顺也；若壳软皮薄，则
必痒塌，此毒胜气，为逆也。结痂之形，痂如螺壳，先结先落，后结后落，此气胜毒，为
顺也；若痂薄如麸，溃烂粘聚，此毒胜气，为逆也。此痘形顺逆之大略也。
额头、心部、下巴、肾脏、鼻子、脾脏所属的部位，左脸颊是肝脏的位置，右脸颊是肺脏的区域。全身分布主要归属于面部的是胃经，头部和背部属于膀胱经的疆域，腰部属于肾脏的范围。心脏和肺部位于胸部和膈肌区域，肝脏和胆腑位于胁肋部，腹部和四肢归属于脾脏以及大肠和小肠。心包络的络脉联系着脏腑，三焦之气遍布周身没有固定的方位。
【注】小儿出痘疹，从头部面部一直到全身，各有脏腑所属的部位，治疗者必须详细观察部位来判断吉凶。比如额头先出现痘点，这是毒气发于心脏；下巴先出现痘点，这是毒气发于肾脏；左脸颊先出现痘点，这是毒气发于肝脏；右脸颊先出现痘点，这是毒气发于肺脏；鼻子先出现痘点，这是毒气发于脾脏。面部属于胃经的部位，头部和背部属于膀胱经的部位，腰部属于肾经的部位，胸膈属于心和肺两经的部位，胁肋旁侧属于肝和胆两经的部位，肚腹和四肢属于脾、大肠、小肠三经的部位。至于心包络，它是周身脂膜的络脉，连接百骸和脏腑。三焦是周身水谷精微之气，充满躯壳和脏腑。凡是全身发出痘疹，都从此处发出，所以没有一定的固定部位。
痘形出现痘点时，喜欢尖圆形状，厌恶像蚊子叮咬的痕迹、热痱子、寒栗或蚕种那样的形态。痘疹起胀时，逐渐绽开、充盈肥满为顺证；如果顶部平坦不突起、板结坚实则难治。痘疹生浆时，收敛束紧、外形完固为顺证；如果质地软嫩、皮薄、瘙痒塌陷则为逆证。痘疹结痂时，如螺壳般先后脱落为顺证，最忌讳痂皮薄如麦麸、溃烂粘连。
【注】痘形的形成，是“气”的作用。如果气胜过毒，那么毒就被气驾驭，毒气得以解除，所以为顺证；如果毒胜过气，那么气被毒侵蚀，气力衰竭，所以为逆证。如果气和毒势均力敌，那么局势处于危险状态，只在于医生调理治疗得当，使危险转变为顺证。比如刚开始出来的痘形，顶尖而根部圆润，这是气胜毒，属于顺证；如果隐没如同蚊子叮咬，或者像热痱子、寒栗、蚕种，这是毒胜气，属于逆证。起胀时的痘形，逐渐绽开、充盈肥满，这是气胜毒，属于顺证；如果顶部平坦不突起，板结坚实不绽开，这是毒胜气，属于逆证。成浆时的痘形，根部红润、收敛束紧，痘壳完固，这是气胜毒，属于顺证；如果壳软皮薄，则必然瘙痒塌陷，这是毒胜气，属于逆证。结痂时的痘形，痂皮如螺壳，先结的先落，后结的后落，这是气胜毒，属于顺证；如果痂皮薄如麦麸，溃烂粘连聚集，这是毒胜气，属于逆证。这是痘形顺逆的大致情况。
The forehead, heart region, chin, kidney area, nose, and spleen zone correspond to specific locations. The left cheek is the position of the Liver (Gan), and the right cheek is the region of the Lung (Fei). The distribution across the body primarily associates the face with the Stomach (Wei) meridian; the head and back belong to the Bladder (Pangguang) meridian's domain, while the waist belongs to the Kidney (Shen) scope. The Heart (Xin) and Lungs reside in the chest and diaphragm areas; the Liver and Gallbladder (Dan) are located in the hypochondriac regions; the abdomen and limbs belong to the Spleen (Pi) as well as the Large Intestine (Dachang) and Small Intestine (Xiaochang). The collateral vessels of the Pericardium (Baoluo) connect the Zang-Fu organs, while the Qi of the Sanjiao (Triple Burner) permeates the entire body without fixed boundaries.
[Note] When children develop smallpox or chickenpox (Douzhen), from the head and face down to the whole body, each part corresponds to specific Zang-Fu organ regions. Practitioners must carefully observe these locations to determine auspiciousness or ominous signs. For instance, if spots first appear on the forehead, the toxin originates from the Heart; if on the chin, from the Kidneys; if on the left cheek, from the Liver; if on the right cheek, from the Lungs; if on the nose, from the Spleen. The face belongs to the Stomach meridian; the head and back belong to the Bladder meridian; the waist belongs to the Kidney meridian; the chest and diaphragm belong to the Heart and Lung meridians; the hypochondriac sides belong to the Liver and Gallbladder meridians; the abdomen and limbs belong to the Spleen, Large Intestine, and Small Intestine meridians. As for the Pericardium, it consists of the collateral vessels of the subcutaneous fat membranes throughout the body, connecting the bones and Zang-Fu organs. The Sanjiao contains the essence-Qi of water and grain throughout the body, filling the shell and organs. Since all rashes erupt from here, there is no single fixed location.
Regarding the shape of the rash, when spots appear, a pointed and round form is favorable, whereas forms resembling mosquito bites, heat pruritus (Maire), cold chills, or silkworm seeds are unfavorable. During the swelling stage, gradual expansion and plumpness indicate a favorable course (Shun); a flat, non-protruding, hard, and solid texture indicates difficulty in treatment. During the pustule formation stage, tight contraction and intact appearance indicate favorability; soft, thin-skinned, itchy, and collapsed textures indicate an unfavorable course. During the scabbing stage, scabs falling off sequentially like snail shells indicate favorability; the most undesirable outcome is thin scabs like bran that ulcerate and stick together.
[Note] The formation of rash shapes is driven by "Qi" (Vital Energy). If Qi overcomes the toxin, the toxin is controlled and resolved, indicating a favorable course; if the toxin overcomes Qi, Qi is eroded and exhausted, indicating an unfavorable course. If Qi and toxin are balanced, the situation is precarious, depending on the physician's appropriate regulation to transform danger into safety. For example, initially emerging spots that are pointed at the apex and round at the base indicate Qi overcoming the toxin, which is favorable; hidden spots resembling mosquito bites, heat pruritus, cold chills, or silkworm seeds indicate toxin overcoming Qi, which is unfavorable. In the swelling stage, gradual expansion and plumpness indicate Qi overcoming the toxin (favorable); flat, non-protruding, hard, and unexpanded textures indicate toxin overcoming Qi (unfavorable). In the pustule stage, red bases with tight contraction and intact shells indicate Qi overcoming the toxin (favorable); soft shells and thin skin leading to itching and collapse indicate toxin overcoming Qi (unfavorable). In the scabbing stage, scabs like snail shells falling off in sequence indicate Qi overcoming the toxin (favorable); thin scabs like bran with ulceration and adhesion indicate toxin overcoming Qi (unfavorable). This summarizes the general principles of favorable and unfavorable rash shapes.
