人身血气，昼行阳，夜行阴，自平旦寅时从中焦注手太阴肺经，卯时注手阳明
大肠经，辰时注足阳明胃经，巳时注足太阴脾经，午时注手少阴心经，未时注手太
阳小肠经，申时注足太阳膀胱经，酉时注足少阴肾经，戌时注手厥阴心胞经，亥时
注手少阳三焦经，子时注足少阳胆经，丑时注足厥阴肝经。血气循行，不可太过，不
可不及，候气失时，炎眚立见。且人之手足，各有三阴三阳，手之三阴，从脏走至
手，手之三阳，从手走至头；足之三阳，从头下走至足，足之三阴，从足上走入腹，共
合十二经络。更有曰∶凡子、午、卯、酉
日，阴交于阳，气不足，其痘多攻；寅、申、巳、亥日，阳会于阴，血不足，其痘多剥。
辰日阳气行下，血留不进，其痘补血，戌日阴气行上，气留不足，其痘补气；丑未
日气血均行，其痘多吉；此以阴阳立说也。然人身气血虚实，一览可知，且性禀阴阳
各异，岂可拘一定之时候，以概不一之性禀哉。
一日、二日，胎毒自肾而发，至骨髓之分。二日、三日，传心血脉之分。三日、
四日，传脾胃肌肉之分。四日、五日，传至肝筋之分。五日、六日、传肺皮毛之表。
七日、八日，脓浓渐干而愈，否则为倒靥，或成痈肿矣。
肝为水泡，其色青小，是即俗谓水痘也。肺为脓泡，稠浊色白而大，是即俗谓
痘子也。心为 而主血，其色赤而小次于水泡，是即俗谓 子也。脾为疹，其色浅黄而次于 ，是即俗谓麻子也。
人体的血气，白天运行于阳经，夜晚运行于阴经。从清晨寅时开始，血气从中焦注入手太阴肺经；卯时注入手阳明大肠经；辰时注入足阳明胃经；巳时注入足太阴脾经；午时注入手少阴心经；未时注入手太阳小肠经；申时注入足太阳膀胱经；酉时注入足少阴肾经；戌时注入手厥阴心包经；亥时注入手少阳三焦经；子时注入足少阳胆经；丑时注入足厥阴肝经。
血气的循行，不可太过分，也不可不及，如果候察气血运行的时机出现失误，炎症灾祸立刻就会显现。况且人的手足，各有三条阴经和三条阳经。手的三条阴经，从内脏走向手部；手的三条阳经，从手部走向头部；足的三条阳经，从头部向下走向足部；足的三条阴经，从足部向上走入腹部，合起来共十二条经络。
又有说法称：凡是逢子、午、卯、酉日，阴气交于阳气，气不足，痘疮多攻冲（指病情剧烈）；逢寅、申、巳、亥日，阳气会于阴气，血不足，痘疮多剥落（指结痂脱落）。逢辰日，阳气下行，血液停留而不进，治疗痘疮应补血；逢戌日，阴气上行，气停留而不足，治疗痘疮应补气；逢丑、未日，气血均匀运行，痘疮多吉利。这是以阴阳理论立说的。然而人身气血的虚实，一目了然，且人的禀赋阴阳各不相同，怎么能拘泥于固定的时辰，来概括不一的禀赋呢？
第一日、第二日，胎毒从肾脏发出，到达骨髓的部位。第二日、第三日，传变至心脏血脉的部位。第三日、第四日，传变至脾胃肌肉的部位。第四日、第五日，传变至肝脏筋脉的部位。第五日、第六日，传变至肺脏皮毛的表面。第七日、第八日，脓液逐渐干燥而痊愈，否则就会变成倒靥（痘疮内陷），或者形成痈肿。
肝脏对应水泡，颜色青小，这就是俗称的水痘。肺脏对应脓泡，稠浊色白且大，这就是俗称的痘子（天花）。心脏对应赤点（原文缺字，据上下文及中医常识补为“赤点”或类似描述，此处依原文留白处理但翻译需通顺，结合后文“俗谓...子”，通常指麻疹类或特定痘症，原文此处有脱漏，译为“心脏表现为红色斑点...”），主司血液，颜色赤红且小，次于水泡，这就是俗称的[缺失]子。脾脏对应疹，颜色浅黄且次于[缺失]，这就是俗称的麻子（麻疹）。
The blood and qi of the human body circulate in the Yang meridians during the day and in the Yin meridians at night. Starting from the Yin hour (3:00-5:00 AM) at dawn, the blood and qi flow from the Middle Jiao into the Lung Meridian of Hand-Taiyin; at the Mao hour (5:00-7:00 AM), they enter the Large Intestine Meridian of Hand-Yangming; at the Chen hour (7:00-9:00 AM), they enter the Stomach Meridian of Foot-Yangming; at the Si hour (9:00-11:00 AM), they enter the Spleen Meridian of Foot-Taiyin; at the Wu hour (11:00 AM-1:00 PM), they enter the Heart Meridian of Hand-Shaoyin; at the Wei hour (1:00-3:00 PM), they enter the Small Intestine Meridian of Hand-Taiyang; at the Shen hour (3:00-5:00 PM), they enter the Bladder Meridian of Foot-Taiyang; at the You hour (5:00-7:00 PM), they enter the Kidney Meridian of Foot-Shaoyin; at the Xu hour (7:00-9:00 PM), they enter the Pericardium Meridian of Hand-Jueyin; at the Hai hour (9:00-11:00 PM), they enter the Sanjiao Meridian of Hand-Shaoyang; at the Zi hour (11:00 PM-1:00 AM), they enter the Gallbladder Meridian of Foot-Shaoyang; and at the Chou hour (1:00-3:00 AM), they enter the Liver Meridian of Foot-Jueyin.
The circulation of blood and qi should be neither excessive nor insufficient. If the timing of Qi is missed or mishandled, inflammatory disasters will appear immediately. Furthermore, each hand and foot has three Yin and three Yang meridians. The three Yin meridians of the hands run from the Zang organs to the hands; the three Yang meridians of the hands run from the hands to the head; the three Yang meridians of the feet run from the head down to the feet; and the three Yin meridians of the feet run from the feet up into the abdomen, totaling twelve meridians.
There is another theory stating: On days of Zi, Wu, Mao, and You, Yin intersects with Yang, resulting in Qi deficiency, where pox lesions tend to attack aggressively; on days of Yin, Shen, Si, and Hai, Yang meets Yin, resulting in Blood deficiency, where pox lesions tend to peel off. On Chen days, Yang Qi moves downward, and Blood stagnates without advancing, so treating pox requires nourishing Blood; on Xu days, Yin Qi moves upward, and Qi stagnates and becomes insufficient, so treating pox requires tonifying Qi; on Chou and Wei days, Qi and Blood circulate evenly, making the prognosis for pox generally auspicious. This theory is established based on Yin and Yang. However, the deficiency and excess of Qi and Blood in the human body can be known at a glance. Since individual constitutions vary in Yin and Yang, how can one rigidly adhere to fixed times to generalize over diverse constitutions?
On the first and second days, fetal toxin emerges from the Kidneys, reaching the level of the bone marrow. On the second and third days, it transmits to the level of the Heart and blood vessels. On the third and fourth days, it transmits to the level of the Spleen and Stomach muscles. On the fourth and fifth days, it transmits to the level of the Liver and sinews. On the fifth and sixth days, it transmits to the exterior of the Lungs and skin/hair. By the seventh and eighth days, the pus gradually dries up, leading to recovery; otherwise, it may become inverted pox (Dao Ye) or form carbuncles and swellings.
The Liver corresponds to water blisters, which are blue-green and small; this is commonly known as chickenpox (Shui Dou). The Lungs correspond to purulent blisters, which are thick, turbid, white, and large; this is commonly known as smallpox (Dou Zi). The Heart corresponds to red spots [text missing], governing Blood; these are red and small, smaller than water blisters; this is commonly known as [missing character] zi. The Spleen corresponds to macules/rashes, which are pale yellow and smaller than [missing text]; this is commonly known as measles (Ma Zi).
