The treatment principles for postpartum diseases have been discussed extensively by predecessors, unlike warm diseases which are mixed into the *Treatise on Cold Damage* (*Shanghan Lun*) without clear standards. However, predecessors' views also occasionally contained biases, and they were scattered among various books. Modern readers fail to collect and select carefully from their studies, resulting in adhering to outdated practices and taking shortcuts, which has become a custom. Here, I specifically point out the correct path; learners who follow this guidance will progress and not deviate from the right way. This treatise does not record everything; it supplements missing ancient methods, discusses biased ones, rectifies chaotic folk practices, and highlights effective clinical experiences.

The theory of "postpartum convulsions" (Jingfeng) has existed for a long time. Mr. Fang Zhongxing refuted it most thoroughly, so I will not discuss it further here. The *Jin Gui Yao Lue* states that new mothers suffer from three diseases: one is Jing disease (Spasm), characterized by stiffness of the neck and back and opisthotonos; two is Yumao (Depressed Dizziness/Vertigo), characterized by dizziness and blurred consciousness; and three is difficulty in defecation. After childbirth, blood deficiency leads to excessive sweating and susceptibility to wind pathogens, thus causing Spasm; loss of blood followed by sweating leads to Depressed Dizziness; depletion of body fluids and dryness of the stomach lead to difficulty in defecation. When a postpartum woman suffers from Depressed Dizziness, her pulse is weak and faint, she vomits and cannot eat, her stool becomes hard, and only her head sweats. The reason for this is that blood deficiency causes Qi rebellion upward (Jue), and Qi rebellion necessarily causes dizziness. For a patient with Depressed Dizziness to recover, there must be profuse sweating throughout the body. Because blood deficiency causes Yin collapse at the lower jiao, solitary Yang floats upward and outward, hence only the head sweats. Therefore, it is said that postpartum women tend to sweat because Yin blood is depleted and deficient, while Yang qi is relatively excessive; thus, sweating should occur to restore the balance of Yin and Yang. If the stool is hard, vomiting prevents eating, Xiao Chai Hu Tang (Minor Bupleurum Decoction) is the primary formula. If the illness resolves and appetite returns, but fever recurs after seven or eight days, this indicates excess heat in the stomach, and Da Cheng Qi Tang (Major Order the Qi Decoction) is the primary formula. According to this discussion, the general trend of postpartum diseases is comprehensively covered, while the formulas mentioned are designed for the specific syndrome of wind-strike following sweating. Therefore, Shen Munan stated that Zhang Zhongjing's original intent was to clarify that although postpartum Qi and Blood are deficient, if excess syndromes exist, they should be treated as excess; one should not hesitate due to deficiency, lest the condition worsen.

However, there are cases where postpartum women do not contract wind but suffer from the three major syndromes of Depressed Dizziness, Spasm/Jue, and difficulty in defecation due to internal organ dysfunction. Generally, blood deficiency leads to Qi rebellion (Jue), isolated Yang leads to dizziness (Yumao), and shortness of body fluids leads to difficulty in defecation. In cases of Depressed Dizziness and sweating, the pulse is often surging and hollow (Kou pulse); in cases of Spasm and Jue, the pulse is wiry and rapid. Ye Tianshi referred to this as "internal stirring of Liver Wind" (Ganfeng Neidong). I frequently cure these conditions using Sanjia Fumai Tang (Three-Shells Pulse-Restoring Decoction), Da Ding Feng Zhu (Great Wind-Calming Pearl) and Xiao Ding Feng Zhu (Small Wind-Calming Pearl), as well as Zhuanxi Dasheng Gao (Special Absorption Life-Nourishing Paste) (specific methods and notes are recorded in the Lower Jiao Chapter). The depth and sequence of treatment are adjusted according to the situation.
