Postpartum metrorrhagia (postpartum heavy bleeding) is caused by excessive vaginal discharge, leading to severe deficiency of blood and qi. If the body has not yet recovered its equilibrium, it may be triggered by overexertion or fright. Treatment should focus on tonifying the Heart and Spleen to control the blood. If there is persistent fullness and pain in the lower abdomen accompanied by a pulse that is excess, large, tight, and rapid, this indicates exhaustion of Liver Yin and collapse of Liver Qi, which is difficult to treat. If the lower abdomen is distended and painful upon palpation, this signifies the presence of intra-abdominal blood stasis; one must not hastily stop the bleeding, otherwise it will inevitably lead to prolonged dripping.

Postpartum difficulty in defecation arises from a lack of blood nourishing the intestines. The Large Intestine is the official responsible for conduction, where transformation and excretion occur. Postpartum consumption of fluids leads to dryness in the Stomach, preventing the downward transmission of essence and nutrients, causing accumulation of waste and resulting in difficult defecation. This is due to the excessive loss of blood and qi, leading to the depletion of internal fluids. However, the Large Intestine governs fluids (Jin), and the Small Intestine governs liquids (Ye). Both intestines rely on the Yang Qi of the Stomach to transport fluids to the Upper Jiao. Now, following postpartum extreme deficiency, the original Qi of the Stomach is already depleted, and the fluids of both intestines are damaged; thus, difficulty in defecation is inevitable. Treatment should only regulate the Middle Jiao and nourish blood; one must absolutely avoid using solely Semen Cannabis (Hemp Seed) and Fructus Aurantii (Bitter Orange), as this would merely consume the vital energy generating within the intestines and stomach.

Regarding postpartum strangury and urinary retention, *San Yin Fang* states: "During pregnancy, one should stabilize the fetus; after delivery, one should eliminate blood stasis." These two statements are most critical. If strangury occurs during pregnancy, it may be due to Qi deficiency failing to transform fluids; Ginseng Radix et Rhizoma (Ren Shen) should be used to tonify Qi and stabilize the fetus, avoiding excessive use of diuretic herbs. If strangury occurs postpartum, it may be due to obstruction by foul blood; Epilobii Herba (Epilobium) and Polygoni Multiflori Caulis (Qumai) along with Paeoniae Radix Rubra (Mudanpi) or more commonly here referring to Polygoni Multiflori Caulis? No, Qumai is Epilobii Herba, Puhuang is Spora Typhae (Pollen Typhae) should be used as key herbs. If there is Blood deficiency with heat stagnation, Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill) and Xiaoyao San (Free and Easy Wanderer Powder) should be used to tonify Yin and nourish Blood, nourishing the source of transformation, assisted by herbs that guide out blood stasis. Furthermore, some cases arise from careless midwifery causing damage to the uterus, leading to dripping strangury. Zhu Danxi stated: A Mrs. Xu suffered from this condition in her prime. He reasoned that if external muscle tears can be repaired, internal injuries might also be treatable. Upon palpating a very deficient pulse, he realized that those with difficult labor are mostly Qi deficient. After delivery, blood and Qi are even more deficient, requiring vigorous tonification. He prescribed Shen Shu Gao (Ginseng and Atractylodes Paste) decocted with Pig or Sheep Uterus Soup, to be drunk when extremely hungry. Within one month, the patient stabilized, allowing blood and Qi to grow rapidly so the uterus could repair itself; delaying treatment would make success difficult.
