When delivery occurs before the gestational months are complete and the fetal qi (vital energy) is not fully formed, it is called Ban Chan (Half Delivery). This is generally due to the deficiency of Qi in the Chong and Ren meridians in the pregnant woman, which fails to nourish the fetus, leading to unstable fetal qi. Alternatively, it may result from external trauma such as bumps, sprains, or falls, causing damage and agitation to the Qi and Blood. It can also be caused by febrile diseases or warm malaria. Zhang Zhongjing stated: "Cold pathogen and deficiency interact," which is named Ban Chan. He further said that Ban Chan is commonly referred to as Xiao Chan (Small Delivery) in folk terms; whether it occurs at three or four months or five or six months, it is all considered Ban Chan because the male or female fetus has already taken shape. Additionally, it may be caused by worry, fear, sudden rage, excessive grief, overexertion, physical injury from blows, or exposure to summer heat. One must strictly avoid using Hei Shen San (Black Divine Powder), as it contains hot-natured herbs, which might induce other illnesses. Instead, formulas such as Yu Zhu San (Jade Candle Powder) and He Jing Tang (Harmonizing Meridian Decoction) should be used. *Bian Chan Xu Zhi* (Necessary Knowledge for Childbirth) states: "Small delivery must not be underestimated; convalescence should be ten times more intensive than normal delivery." It further states: "After half delivery, muscle tissue may rot; one must tonify the deficiency, promote muscle growth, replenish Qi and Blood, dispel wind pathogens, and nourish the Zang organs. Convalescence exceeding that of normal delivery by tenfold will ensure recovery without exception. This point requires careful consideration."

Quansheng Huoxue Tang (Complete Life Blood-Invigorating Decoction) (from *Lanshi Micang*): Treats women experiencing fainting, loss of consciousness, closed eyes, and lack of sensation after delivery or half delivery with spotting.
This occurs because blood suddenly drains away; when tangible blood leaves, the Shen (Spirit) loses nourishment. The Heart and Bao Luo (Uterine Collaterals) belong to Ministerial Fire and Sovereign Fire; they are peaceful with blood and endangered without it. Excessive fire causes fainting. If fire attacks the Lung, it leads to closed eyes and unconsciousness. This is sudden loss of Yin Blood failing to anchor Yang, resulting in blood deficiency. Often, physicians use Shi (Talcum), Gancao (Licorice), and Shigao (Gypsum), which are acrid-sweet and overly cold herbs that drain Qi-heat. This constitutes draining Qi alongside Blood deficiency, i.e., draining Yang alongside Yin deficiency, injuring both and creating deficiency-wasting disease. Fainting is due to Heat in the Upper Jiao (Heart and Lungs). This is formless Heat. Using cold herbs to force it downward ignores that Upper Jiao diseases belong to the Exterior and are Yin patterns, cured by sweating. Purging instead risks death from sudden Qi-Blood depletion. As stated in *Neijing*: When pathogenic Qi is deficient, tonification is preferred over purgation. Closed-eye diseases belong to Yin, favoring sweating over purgation. In Shanghan (Cold Damage) Yu Mao (Depression and Vertigo), sweating brings cure. Thus, cold herbs are prohibited. Delivery and half delivery do not inherently damage Yuan Qi; only sudden blood loss occurs. Lost blood must be replenished. Tonifying blood restores Shen. Normally, blood descends and is lost; here, it must be tonified and lifted. The Heart receives blood to nourish Shen, preventing dullness. Sudden blood descent mimics Autumn/Winter dominance; lifting it assists Yang, opening eyes and clearing Shen. This formula tonifies, nourishes, generates blood, and benefits Yang to address insufficiency in the Hand and Foot Jueyin meridians.
