产后出现食物未经消化即排出（完谷不化）的情况，是因为分娩时的劳累和疲倦损伤了脾气，导致脾胃的运化和转输功能迟缓。水谷进入胃中，必须依赖脾气的运化，才能散布到肺脏，进而通调水道，将气布散至五脏六腑以滋养人体。如今因产程劳累疲倦导致脾伤，所以失去了转输的功能，致使冲和之气不能正常运化，冷物便原样排出，这种病名为飧泄（大便稀溏且含有未消化食物）。另外，如果饮食过量，损伤了脾胃，也会导致完谷不化，俗称水谷痢。然而，在产后三天内，恶露血块尚未消散，此时若患此脾败胃弱的病症，不可立即加入白术、苍术等燥湿健脾之品，适宜服用生化汤，加入益智仁、砂仁，以轻微温养胃气，等到血块消散后，可以加入人参、白术、苍术来补气，加入肉豆蔻、木香、砂仁、益智仁来温胃，加入柴胡、升麻来引胃中清气上升，加入泽泻、陈皮、茯苓以利水渗湿，这是上策。

Postpartum indigestion with undigested food in stool (Wangu Buhua) occurs due to spleen injury caused by labor fatigue, resulting in delayed transportation and transformation. When water and grain enter the stomach, they must be processed by the Spleen to disperse to the Lung, thereby regulating the water passages, so that Qi can be distributed to the five Zang organs to nourish the body. Now, due to postpartum fatigue injuring the Spleen, the function of transportation is lost, causing the harmonious Qi to fail in transformation, leading to cold substances being excreted intact. This condition is named Sun Xie (diarrhea with undigested food). Additionally, excessive diet damaging the Spleen and Stomach can also lead to indigestion with undigested food, commonly known as Shuigu Li (water-grain dysentery). However, within three days postpartum, when blood stasis has not yet dissipated, if this syndrome of Spleen failure and Stomach weakness occurs, one should not abruptly add Atractylodis Rhizoma (Baizhu) or Atractylodis Macrocephalae Rhizoma (Canshu). It is appropriate to administer Shenghua Tang (Life-Restoring Decoction) added with Alpiniae Oxyphyllae Fructus (Yizhi) and Amomi Fructus Rotundus (Xiangsha) to slightly warm the Stomach Qi. Wait until the blood stasis dissipates before adding Ginseng Radix (Renshen), Atractylodis Rhizoma (Baizhu), and Atractylodis Macrocephalae Rhizoma (Canshu) to tonify Qi; Mu Dou Kou (Nutmeg), Aucklandiae Radix (Muxiang), Amomi Fructus Rotundus (Sharen), and Alpiniae Oxyphyllae Fructus (Yizhi) to warm the Stomach; Bupleuri Radix (Chaihu) and Cimicifugae Rhizoma (Shengma) to guide clear Yang from the Stomach upward; and Alismatis Rhizoma (Zexie), Citri Reticulatae Pericarpium (Chenpi), and Poria (Fuling) to promote diuresis. This is the superior strategy.
Jiawei Shenghua Tang (Modified Life-Restoring Decoction): Treats postpartum indigestion with undigested food within three days, used for patients who were constitutionally weak before delivery and suffer from this syndrome.

If there is a need to drain water, add Alismatis Rhizoma (Zexie) 8 fen and Akebia Stem (Mutong) 8 fen.
Modifications: For abdominal pain, add Amomi Fructus Rotundus (Sharen) 8 fen. For thirst, add Ophiopogonis Radix (Maidong) 2 qian and Schisandrae Fructus (Wuweizi) 10 grains. For watery diarrhea with cold signs, add Dried Ginger (Ganjiang) 1 qian and Aucklandiae Radix (Muxiang) 4 fen. For food stagnation presenting with yellow complexion, add Medicated Leaven (Shenqu) 2 qian and Hordeum Vulgare Sprout (Maiya) 2 qian to digest wheat-based foods; add Amomi Fructus Rotundus (Sharen) 2 qian and Crataegi Fructus (Shanzha) 5 grains to digest meat-based foods. If diarrhea and dysentery persist for a long time, with weak Stomach Qi and indigestion with undigested food, it is advisable to warm and assist Stomach Qi using Liujunzi Tang (Six Gentlemen Decoction) added with Aucklandiae Radix (Muxiang) 5 fen and processed Nutmeg (Zhi Rougu) 1 piece.
