产后腑脏劳伤，血虚不复，而风邪乘之，搏于血气，使气不宣泄，而痞涩生热，或肢节
烦愦，或唇干燥，但因虚生热，故谓之虚热也。
夫产损动腑脏，劳伤气血。轻者，节养将摄，盈月便得平复；重者，其日月虽满，气血
犹未调和，故虚羸也。然产后虚羸，将养失所，多沉滞劳瘠，乍起乍卧。风冷多则辟瘦，颜
色枯黑，食饮不消；风热多则 退、虚乏，颜色无异于常，食亦无味。甚伤损者，皆
着床，此劳瘠也。
产则血气劳伤，腑脏虚弱，而风冷客之，风冷搏血气，血气则不能自温于肌肤，使人虚
乏疲顿，致羸损不平复，谓之风冷虚劳。若久不瘥，风冷乘虚而入腹，搏于血则痞涩；入肠
则下痢不能养，或食不消；入子脏，并胞脏冷，亦使无子也。
夫汗，由阴气虚而阳气加之，里虚表实，阳气独发于外，故汗出也。血为阴，产则伤血
，是为阴气虚也；气为阳，其气实者，阳加于阴，故令汗。汗出而阴气虚弱不复者，则汗出
不止。凡产后皆血虚，故多汗，因之遇风，则变为痉。纵不成痉，则虚乏短气，身体柴瘦，
唇口干燥，久普通经水断绝，津液竭故也。
肝藏血，心主血脉。产则营损肝心，伤动血气。血为阴，阴虚面阳气乘之，即令汗血。
此为阴气大虚，血气伤动，故因汗血出，乃至毙人。
Blood and Qi are both injured during childbirth, leading to deficiency and exhaustion of the Zang-Fu organs. When Qi fails to circulate freely within, it causes vexation (restlessness).
After childbirth, the Zang-Fu organs are damaged by overwork, and blood deficiency prevents recovery. Wind pathogen takes advantage of this weakness to invade, clashing with Blood and Qi, preventing their free dissemination. This results in stagnation,涩滞 (obstruction), and generation of heat. Symptoms may include vexation and dizziness in the limbs and joints, or dryness of the lips. Since the heat arises from deficiency, it is termed Deficient Heat (Xu Re).
Childbirth damages the Zang-Fu organs and exhausts Blood and Qi. In mild cases, dietary regulation and rest allow recovery within a month. In severe cases, even after sufficient time has passed, Blood and Qi remain unharmonized, resulting in emaciation and weakness. However, if postpartum weakness and emaciation are managed improperly, one may suffer from chronic stagnation and wasting diseases (Lao Ji), alternating between rising and lying down. Excessive exposure to wind-cold leads to emaciation, dark and withered complexion, and indigestion; excessive exposure to wind-heat leads to feverish sensations and fatigue, normal complexion, and loss of appetite. Severe injuries result in being bedridden, which is classified as Wasting-Thirst/Wasting Disease (Lao Ji).
Childbirth injures Blood and Qi, weakening the Zang-Fu organs. If wind-cold invades and clashes with Blood and Qi, they fail to warm the skin and muscles, causing fatigue, debility, and failure to recover, known as Wind-Cold Deficiency Consumption (Feng Leng Xu Lao). If untreated for a long time, wind-cold enters the abdomen due to deficiency. Clashing with Blood, it causes obstruction; entering the intestines, it causes diarrhea and malabsorption or indigestion; entering the uterus and causing coldness in the Bao Palace (Uterus), it leads to infertility.
Sweat occurs when Yin Qi is deficient and Yang Qi becomes relatively excess, creating interior deficiency and exterior excess. Yang Qi alone radiates outward, causing sweating. Blood belongs to Yin; childbirth injures Blood, constituting Yin deficiency. Qi belongs to Yang; if Qi is substantial, Yang adds to Yin, causing sweat. If Yin Qi remains weak and does not recover after sweating, sweating continues incessantly. Postpartum women generally have Blood deficiency, making them prone to sweating. If exposed to wind in this state, it may transform into Spasm Disease (Jing Bing), characterized by stiffness and convulsions. Even if spasm does not occur, symptoms include debility, shortness of breath, emaciation, dry lips and mouth, and eventually amenorrhea due to depletion of body fluids (Jin Ye).
The Liver stores Blood, and the Heart governs the Blood vessels. Childbirth damages Ying (Nutrient) Qi and affects the Liver and Heart, disturbing Blood and Qi. Blood is Yin; when Yin is deficient, Yang attacks, leading to Hemorrhagic Sweat (Han Xue). This is caused by severe Yin deficiency and disturbance of Blood and Qi, causing blood to exit with sweat, which can be fatal.
