*Baojian* records: Song Dynasty physician Chu Cheng formulated special prescriptions for nuns, Buddhist nuns, and widows, which was purposeful. These two groups live in seclusion, possessing Yin without Yang; their desires arise but are often unfulfilled, leading to a conflict between Yin and Yang. This manifests as alternating chills and fever, closely resembling warm malaria (Wen Nue). If prolonged, it evolves into consumptive disease (Lao). The *Records of the Grand Historian* (*Shiji*), in the biography of Cang Gong, records that Han Nu, a maid-servant of King Jibei, suffered from lower back pain and alternating chills and fever. Many physicians attributed this to pathogenic cold-heat. Cang Gong said, "This illness arises from desiring a man but being unable to obtain one." How did he know? Upon pulse diagnosis, he found the Liver pulse (Gan Mai) was wiry (Xian) and emerged at the Cun Kou position. Thus, he deduced this. Generally speaking, men are governed by Essence (Jing), while women are governed by Blood (Xue). When men's Essence is abundant, they desire sexual intercourse; when women's Blood is abundant, they conceive. If the Jueyin pulse is wiry and emerges at the Cun Kou, extending even to the Yu Ji area, it indicates an excess of Yin. Therefore, it can be understood that Chu's statements were well-founded.

*Bingji Yaojiao* states: In treating diseases related to pregnancy and childbirth, one should discuss them according to the Jueyin Meridian (Jueyin Jing), without violating Stomach Qi (Wei Qi) or the Upper, Middle, and Lower Jiao (San Jiao). This constitutes the "Three Prohibitions" (San Jin): no sweating (Han), no purgation (Xia), and no diuresis (Li Di Xiao Bian). Sweating induces conditions similar to premature purgation in Cold Damage (Shang Han); purging affects the Spleen (Pi) causing rapid pulse; diuresis depletes internal fluids, leading to dryness in the Stomach. If herbal preparation avoids these three prohibitions, Ying and Wei (Nutritive and Defensive Qi) will harmonize naturally, and chills and fever will cease. For thirst, Bai Hu Tang (White Tiger Decoction) may be used; if Qi is weak, Huang Qi (Astragali Radix) is added; for stabbing blood pain, Dang Gui (Angelicae Sinensis Radix) is used; for abdominal pain, Shao Yao (Paeoniae Radix Alba) is added. Generally, postpartum diseases complicated by epidemic pathogens are treated by modifying Chai Hu Tang (Bupleurum Decoction); miscellaneous disorders are treated by modifying Si Wu Tang (Four Substance Decoction). One must carefully observe pulses and symptoms before application.

Respectfully noted: The aforementioned prohibitions for pregnancy and childbirth primarily emphasize the importance of the root Qi (Yuan Qi) and underlying pathology. Since etiologies vary, practitioners must employ flexibility. Although *Liangfang* covers prenatal conditions comprehensively, specific treatment protocols for each syndrome are scarce. For instance, formulas for fetal leakage (Tai Lou), fetal pain (Tai Tong), maternal irritability (Zi Fan), and edema (Zi Zhong) generally treat the primary pathology. However, if etiologies differ or complications exist—such as fetal bleeding caused by Qi deficiency or Blood heat, or abdominal pain due to damp-heat—or if physical and mental distress leads to varied medication, where emotional disturbances cause Qi stagnation and Blood chaos, damaging Fetal Qi—even though treatment protocols cannot cover every variation—the hope is that practitioners will deduce and adapt based on clinical presentation. Herein, not all conditions are exhaustively listed; only a few examples of syndrome differentiation and treatment are appended below.
