初生婴儿诊察虎口脉纹，男孩看左手，女孩看右手。食指分为三节，分别称为风关、气关和命关，正常的脉纹颜色与形态应当是隐隐约约且安定的。如果脉纹显现且颜色发生变化，就知道生病了：紫色属于内热，红色属于伤寒，黄色主脾病，黑色主中恶，青色主惊风，白色主疳积。脉纹出现在风关表示病情轻，出现在气关表示病情重，如果出现在命关则性命多难保全。脉纹的大小、弯曲及紫色代表伤食滞热；弯曲且青色代表被人或走兽惊吓；赤色代表被水火或飞禽扑吓；黄色代表雷惊；黑色代表阴痫。脉纹形状如长珠代表伤食，如流珠代表热证，如去蛇代表吐泻，如来蛇代表疳积；弓形在里侧代表感冒，在外侧代表痰热；向左斜代表伤风，向右斜代表寒邪；针形和枪形代表主痰热；透关射指和透关射甲代表性命难全；脉纹呈现乙字形代表抽搐；两个弯曲如钩代表受冷传变；三个弯曲如虫代表误食硬物；水字形代表咳嗽吐泻；环形代表积滞；曲虫形代表惊风；鱼骨形代表形如乱虫有蛔虫缠绕。诊察时需将脉纹的形态与颜色相互参合，医生必须留心仔细观察。
【注】凡是初生婴儿患有疾病的，必须观察虎口叉手处脉纹的颜色和形态，以判断疾病的生死轻重。男孩先看左手食指的次指内侧，女孩先看右手食指的次指内侧。手指的三节，第一节叫风关，第二节叫气关，第三节叫命关。其纹路颜色红黄相间，隐隐不见，就是平安无病；如果纹路颜色紫属内热，红属伤寒，黄为伤脾，黑为中恶，青主惊风，白主疳证。纹路在风关主病轻，气关主病重，如果过命关主病危难治。
Diagnosis of newborn infants involves examining the pulse pattern on the tiger's mouth (the web between the thumb and index finger). For males, the left hand is examined first; for females, the right hand. The index finger is divided into three segments: the Feng Guan (Wind Gate), Qi Guan (Qi Gate), and Ming Guan (Life Gate). A normal pulse pattern appears faint and stable. If the pattern becomes visible and changes in color, illness is present: purple indicates internal heat, red indicates cold damage (Shanghan), yellow indicates spleen disease, black indicates sudden evil attack (Zhong'e), green indicates convulsive wind (Jingfeng), and white indicates malnutrition syndrome (Ganji). A pattern appearing at the Feng Guan indicates mild illness; at the Qi Guan, severe illness; and if it reaches the Ming Guan, the prognosis is critical with high mortality.
Variations in size, curvature, and color correlate with specific etiologies: large or curved purple patterns indicate food stagnation and heat; curved green patterns suggest fright from humans or beasts; red patterns suggest fright from water, fire, or birds; yellow patterns suggest fright from thunder; and black patterns indicate yin epilepsy. Specific shapes correspond to conditions: a shape like a long bead indicates food injury; a flowing bead indicates heat; a "departing snake" shape indicates vomiting and diarrhea; an "arriving snake" shape indicates gan syndrome; an arch shape on the inner side indicates exogenous cold; on the outer side, phlegm-heat; a slant to the left indicates wind invasion; to the right, cold pathogen; needle-like or spear-like shapes indicate phlegm-heat; patterns penetrating to the finger tip or nail bed indicate critical condition; an "Yi" character shape indicates convulsions; two hooks indicate transmission of cold; three worm-like curves indicate ingestion of hard objects; a water-character shape indicates cough and diarrhea; a ring shape indicates food stagnation; a curved-worm shape indicates fright; and fish-bone or chaotic-worm shapes indicate roundworm infestation. Physicians must integrate morphology and color for careful observation.
[Note] For any newborn with illness, one must observe the color and form of the pulse pattern at the tiger's mouth to determine severity and prognosis. Males are examined on the medial aspect of the index finger of the left hand; females on the right. The three segments are named Feng Guan (first segment), Qi Guan (second segment), and Ming Guan (third segment). Reddish-yellow hues that are faint and invisible denote health. Purple denotes internal heat, red denotes cold damage, yellow denotes spleen injury, black denotes sudden evil, green denotes convulsive wind, and white denotes gan syndrome. Patterns at the Feng Guan indicate mild disease; at the Qi Guan, severe disease; and extending beyond the Ming Guan indicates critical, difficult-to-treat disease.
