产后腹痛，先问血块。如有血块，只服生化汤，甚则调失笑散，其块消而痛自止。若风冷乘虚
入腹，或内伤寒凉之物作痛，得人按摩略止。或热物熨之略止，宜加味生化汤。密斋用当归建中汤治
之。冯氏云∶产后恶露；或因外感六淫，内伤七情，致令斩然而止，瘀血壅滞，所下不尽，故令腹痛，
当审因治之。如产后数朝内，饮食如常，忽作腹痛，六脉沉伏，四肢厥冷，此恶血不尽，伤食裹血，
而脉不起也。不可误认气血两虚，而用大补，须兼消导、血行之药。但产后恶露不尽，留滞作痛，亦
常有之。然与虚痛不同，必其由渐而甚，或大小便不行，或小腹硬实，作胀痛极，不可近手，或自下
上冲心腹，或痛极，牙关紧急，有此实症，当速去之。近上者，宜失笑散；近下者，宜通瘀煎。未效，用
决津煎为善。又有腹痛定于一边及小腹者，此是侧卧，败血留滞所致，亦用决津煎为当也。《金
匮》云∶产后腹中 痛，当归生姜羊肉汤主之。盖 痛者，缓缓痛也，属客寒相阻。故以当归通血
分之滞，生姜行气分之寒。君以羊肉者，所谓“形不足，补之以味”，况羊肉又能补气， 痛属气
弱，故宜之。若妇人产当寒月，寒气入产门，脐下胀痛，手不可犯，此寒疝也，亦宜当归生姜羊肉
汤治之。又有产后脾虚，肾虚而为腹痛者，此不由产，而由脏气不足。若脾气虚寒，为呕吐，为食
少，而兼腹痛者，宜五君子煎及六君子汤。若肾气虚寒，为泻为痢，而兼腹痛者，宜胃关煎或理阴
煎主之。若胸膈饱闷，或恶食吞酸，腹痛手不可按，此饮食所伤，治法见伤食门。若食既消而仍
痛，按之不痛，更加头痛烦热、作渴、恶寒、欲呕等症，此是中气被伤，宜温补脾胃为主。若发热
腹痛，按之痛甚，不恶食吞酸，此是瘀血停滞，失笑散消之。若止发热、头痛、腹痛，按之却不
痛，此是血虚，初产生化汤，日久用四物加炮姜、参、术以补之。

Postpartum abdominal pain requires first inquiring about the presence of blood clots. If blood clots are present, only Shenghua Tang (Decoction for Generating New Blood) should be administered; if the condition is severe, Touxiao San (Powder to Make Pain Cease) should be used. Once the clots dissipate, the pain will naturally cease. If wind-cold pathogens invade the abdomen due to deficiency, or if internal injury from cold and raw foods causes pain, slight relief may be obtained through manual massage or application of hot compresses; Jiawei Shenghua Tang (Modified Decoction for Generating New Blood) is appropriate. Mi Zhai (a physician) treats this with Danggui Jianzhong Tang (Cinnamon Twig and Angelica Decoction to Build the Middle). Feng Shi states: Postpartum lochia may be abruptly stopped due to external contraction of the Six Excesses (Wind, Cold, Summerheat, Dampness, Dryness, Fire) or internal injury from the Seven Emotions (Joy, Anger, Worry, Pensive, Sorrow, Fear, Fright), leading to stagnation of retained blood and incomplete discharge, thus causing abdominal pain. The etiology must be investigated for treatment. For instance, within a few days postpartum, if diet remains normal but sudden abdominal pain occurs, with deep and hidden pulses in all six positions and cold extremities, this indicates that evil blood has not been fully expelled, and food stagnation is entangling the blood, preventing the pulse from rising. One must not mistakenly diagnose Qi and Blood deficiency and use heavy tonification; instead, herbs for resolving stagnation and promoting blood circulation must be combined. However, it is also common for lochia to remain unexpelled and cause pain due to stagnation. This differs from deficiency pain; the pain here gradually worsens, accompanied by constipation or urinary retention, hardness and fullness of the lower abdomen, severe distending pain intolerable to touch, or pain rushing upward to the heart and abdomen, or extreme pain causing lockjaw. When such excess symptoms appear, the pathogen must be rapidly eliminated. For pathology located superiorly, Touxiao San (Powder to Make Pain Cease) is suitable; for pathology located inferiorly, Tongyu Jian (Decoction for Unblocking Stasis) is suitable. If ineffective, Juejin Jian (Decoction for Breaking Through the Vessels) is preferable. Abdominal pain fixed on one side or in the lower abdomen is caused by lying on one side leading to stagnation of foul blood; Juejin Jian (Decoction for Breaking Through the Vessels) is also appropriate here. The *Jingui Yaolue* states: For postpartum abdominal cramping pain (*yuan tong*), Danggui Shengyang Roushou Tang (Angelica, Ginger, and Mutton Decoction) is the primary formula. "Cramping pain" refers to slow, lingering pain, attributed to exogenous cold obstruction. Therefore, Dang Gui (Angelica Sinensis Root) is used to unblock stagnation in the blood level, and Sheng Jiang (Fresh Ginger Rhizome) to circulate cold in the Qi level. Mutton is used as the sovereign herb, following the principle "for those deficient in form, nourish with flavor"; moreover, mutton can tonify Qi. Since cramping pain belongs to Qi weakness, this is suitable. If a woman gives birth in cold months, and cold qi enters the uterus (Zimen), causing distending pain below the umbilicus that is intolerable to touch, this is Han Shan (Cold Hernia), which is also treated with Danggui Shengyang Roushen Tang (Angelica, Ginger, and Mutton Decoction). There are also cases of postpartum abdominal pain due to Spleen deficiency and Kidney deficiency, which do not stem directly from childbirth but from insufficiency of Zang-Fu Qi. If Spleen Qi deficiency and cold manifest as vomiting, poor appetite, and concurrent abdominal pain, Wu Junzi Jian (Decoction of Five Gentlemen) and Liujunzi Tang (Six Gentlemen Decoction) are indicated. If Kidney Qi deficiency and cold manifest as diarrhea, dysentery, and concurrent abdominal pain, Weiguan Jian (Decoction for Guarding the Stomach) or Liyin Jian (Decoction for Nourishing Yin) are indicated. If chest and diaphragm fullness, aversion to food, acid regurgitation, and abdominal pain intolerable to pressure occur, this is injury from dietary excess; see the section on Dietary Injury for treatment methods. If food stagnation has resolved but pain persists, and pressing does not aggravate the pain, accompanied by headache, vexatious heat, thirst, aversion to cold, and nausea, this is damage to Middle Qi, requiring warming and tonification of the Spleen and Stomach as the main approach. If fever and abdominal pain occur, with increased pain upon pressure, but no aversion to food or acid regurgitation, this is stagnation of retained blood, treated with Touxiao San (Powder to Make Pain Cease) to resolve it. If there is only fever, headache, and abdominal pain, with no pain upon pressure, this is Blood deficiency. In early postpartum, Shenghua Tang (Decoction for Generating New Blood) is used; after a long duration, Siwu Tang (Four Substances Decoction) plus Pao Jiang (Prepared Ginger Rhizome), Ren Shen (Ginseng Root), and Bai Zhu (Atractylodes Macrocephala Rhizome) are used to tonify.
