产后血晕，因阴血暴虚，孤阳上冒，忽然头旋眼黑，昏闷不醒，急用清魂散，或以童便热服。然有血下
过多而晕者，有血下少而晕者，晕虽同，治法则异。如血下多而晕，神昏烦乱而已，治宜补血清心。如生地、
白芍、当归、茯苓、麦冬、阿胶、人参、龙齿、枣仁等。渴烦汗热，加乌梅、山栀、丹参、浮小麦等。烦热，
去当归，加童便。血下少而晕，乃恶露不下，上抢心，心下满急，神昏口噤，治宜行血破瘀，加生楂肉，桃仁、
牛膝、桂心、归尾、苏木，合失笑散。或用四味散、黑神散、鹿角散、郁金散。若痰火上壅，用导痰汤加朱砂
安神丸。清降治之。有一产妇暴死，但胸微热，陆 诊之曰∶血闷也。以红花煮沸入木桶，寝妇于上
熏之，汤冷加之，遂指动而苏。
一、禁卧。恐气未定，遽卧则恶血上升也。二、禁酒。恐助火升动其阳，致眩晕也。三、禁浴。恐水
湿沁窍，致喘满肿重也。四、禁寒。恐血气凝滞，腹痛吐泻诸变丛生也。五、禁汗。恐风药性升，开泄伤阳也。
六、禁下。恐肠腑津液伤也。七、禁利小便。恐伤肾气蛰藏也。八、禁寒凉药。恐伤胃，或滋瘀痛也。白芍、
地黄、黄芩等皆慎用。九、禁交合早。恐百脉开张，头眩少腹急满也。十、禁起早作劳，不避风寒，不谨食忌，
致滋疾也。
Postpartum blood syncope is caused by the sudden severe deficiency of Yin-blood, leading to the floating and rushing upward of isolated Yang. The patient suddenly experiences dizziness, blacking out, and unconsciousness with a sense of suffocation. Immediate treatment should involve Qinghun San (Clear Soul Powder) or hot administration of child's urine. However, some women faint due to excessive lochia discharge, while others faint due to insufficient lochia discharge. Although the symptom of syncope is the same, the treatment principles differ.
If the fainting is due to excessive lochia discharge, manifesting as coma and restlessness, the treatment should focus on nourishing blood and clearing the heart. Herbs such as Sheng Di Huang (Rehmanniae Radix), Bai Shao (Paeoniae Radix Alba), Dang Gui (Angelicae Sinensis Radix), Fu Ling (Poria), Mai Dong (Ophiopogonis Radix), E Jiao (Colla Corii Asini), Ren Shen (Ginseng Radix), Long Gu (Fossilia Ossis Mastodi), and Zao Ren (Ziziphi Spinosae Semen) may be used. If accompanied by thirst, irritability, sweating, and fever, Wu Mei (Mume Fructus), Shan Zhi (Gardeniae Fructus), Dan Shen (Salviae Miltiorrhizae Radix et Rhizoma), and Fu Xiao Mai (Tritici Levis Fructus) can be added. If only irritability and heat are present, remove Dang Gui and add child's urine.
If the fainting is due to insufficient lochia discharge, it is because lochia fails to descend and turbid blood rushes upward to affect the heart, causing fullness and urgency in the epigastrium, coma, and lockjaw. The treatment should focus on promoting blood circulation and breaking up stasis. Raw Hawthorn Fruit (Shan Zha Rou), Tao Ren (Persicae Semen), Niu Xi (Achyranthis Bidentatae Radix), Gui Xin (Cinnamomi Ramulus Cortex), Dang Gui Wei (Angelicae Sinensis Radix Cauda), and Su Mu (Sappan Lignum) can be added, combined with Shixiao San (Excellent Payment Powder). Alternatively, Siwei San, Heishen San, Lu Jiao San, or Yujin San may be used. If phlegm-fire obstructs upwards, Daotan Tang (Phlegm-Resolving Decoction) plus Zhusha Anshen Wan (Cinnabar Calming Spirit Pill) should be used for clearing and descending.
In one case, a puerpera suddenly died, but her chest was slightly warm. Dr. Lu diagnosed it as "blood obstruction." He boiled Hong Hua (Carthami Flos) in water inside a wooden tub and had the woman sit above it to inhale the steam, adding hot water as it cooled. She soon moved her fingers and regained consciousness.
1. Prohibition of lying down: To prevent rising of turbid blood due to premature recumbency before Qi and Blood have stabilized.
2. Prohibition of alcohol: To prevent alcohol from aiding fire and stirring up Yang, causing dizziness.
3. Prohibition of bathing: To prevent water-dampness from invading orifices, leading to asthma, distension, edema, and heaviness.
4. Prohibition of cold exposure: To prevent stagnation of Qi and Blood, which could generate various complications such as abdominal pain, vomiting, and diarrhea.
5. Prohibition of diaphoresis (sweating): To prevent wind-dispelling herbs from ascending and dispersing, thereby damaging Yang through excessive opening and leakage.
6. Prohibition of purgation: To prevent damage to the fluids of the intestines and bowels.
7. Prohibition of diuresis: To prevent damage to the storing function of Kidney Qi.
8. Prohibition of cold-natured medicines: To prevent damage to Stomach Qi or retention of stasis causing pain. Bai Shao, Di Huang, and Huang Qin should all be used with caution.
9. Prohibition of early sexual intercourse: To prevent the opening of all vessels, leading to dizziness and urgency/fullness in the lower abdomen.
10. Prohibition of early rising and labor: To prevent illness arising from failure to avoid wind-cold and negligence in dietary taboos.
