Postpartum diseases caused by the six qi (Six Excesses: wind, cold, summer-heat, dampness, dryness, fire), except for Taiyang Cold Damage (Taiyang Cold Damage) which follows Master Zhang Zhongjing's methods (for pregnant women with Taiyang Cold Damage, later generations have the Liuhe Tang method), should be sought in the first three chapters of the Sanjiao (Triple Burner) section. Weighing the severity, one should either rapidly eliminate the pathogenic factor, as a troop without provisions values swift battle; or simultaneously protect against deficiency, supporting the righteous qi while driving out the pathogen. Generally, at the onset, rapid clearing is essential, and even in severe cases, purgative methods must be used. I once treated Huang's warm-heat disease during the seventh month of pregnancy, where the fetus was about to move, presenting with excessive excess and excessive heat, protruding eyes, and ulcerated tongue, caused by the previous physician's excessive hesitation. Using Da Chengqi Tang (Major Order the Qi Decoction) once resulted in the subsidence of heat and stabilization of the fetus; the child born from this pregnancy is now twenty-one years old. If the causes of spasm and convulsions due to the six qi are clear as the sun in one's mind, the folk saying of "postpartum convulsive disease" can be dismissed.

Zhu Danxi stated that Baishao (Radix Paeoniae Alba) should not be used postpartum, fearing it would attack the vital energy of life, which is greatly erroneous; it depends on whether it is deficiency-cold or deficiency-heat. If it is deficiency-cold, even if not postpartum, it should not be used; for example, Zhang Zhongjing has the method of removing Baishao from Guizhi Tang (Cinnamon Twig Decoction) and Xiao Qinglong Tang (Minor Blue Dragon Decoction). If it is deficiency-heat, it must be used to gather and nourish Yin. Later generations who are not good at reading books do not know to adhere to the beneficial methods of the ancients but instead memorize these biased errors, causing great harm, which is worth a sigh. Note: Baishao blooms in late spring and early summer, inheriting the complete nature of Jueyin Wind-Wood, and obtaining the qi transformation of Shaoyin Ministerial Fire, rising upward to produce bitterness, thus its flavor is bitter and neutral (Shennong Bencao Jing does not mention sour for Shaoyao, only stating bitter, neutral, and non-toxic; the sour character was added erroneously by later generations). It treats abdominal pain caused by pathogens, removes blood obstruction, breaks firm accumulations, treats cold-hot hernia and masses, stops pain, promotes urination, and benefits qi. How could it be said to attack the vital energy of life? If it attacks shengqi (vital energy), how could Zhang Zhongjing use it as the sovereign herb in Xiaojianzhong Tang (Minor Construct the Middle Decoction) to supplement various deficiencies and insufficiencies? Zhang Yinan discusses this most detailedly in Bencao Chongyuan (Revered Source of Materia Medica).

Danggui (Radix Angelicae Sinensis) and Chuanxiong (Rhizoma Chuanxiong) are important herbs for postpartum conditions, but they are suitable only for blood-cold with stagnation. For blood-deficiency with heat, they must absolutely not be used. Danggui begins to bloom after the Autumnal Equinox, inheriting the pungent and fierce qi of Dry Metal, with an aroma that penetrates exceptionally, surpassing Mahuang (Ephedrae Herba) and Xixin (Asari Radix et Rhizoma); it is just that Mahuang and Xixin lack juice and have thin flavors, whereas Danggui is juicy and rich in flavor. Used appropriately, its efficacy is fastest; used inappropriately, the harm is also profound. In cases of blood loss and deficiency, or floating of lone Yang upwards, hoping for it to tonify blood is foolish! Danggui can only circulate blood, reducing excess and benefiting scarcity, moving quickly and penetrating well, but cannot remain static. Misuse leads to convulsions (spasms/convulsions), and severe convulsions lead to collapse (deviation/collapse). Chuanxiong has wheel-like patterns, and its nature is more urgent than Danggui. Generally, substances whose nature favors unblocking do not favor retaining. People dare not change to using Baishao but recklessly use Danggui and Chuanxiong; how inverted this is!
