Postpartum wind-stroke arises from the injury to Qi and Blood during childbirth, damaging the Zang-Fu organs. If the body has not yet recovered and one rises early to engage in labor, Qi deficiency allows Wind pathogen to take advantage of this weakness. Cold Qi lodges in the skin and meridians, causing pain, bi-syndrome (obstruction), emaciation, and fatigue, making the patient unable to tolerate even slight shortness of breath. When tendons and vessels are affected by Cold, they become spasmodic and deviated; when affected by Warmth (Heat), they become lax and weak. If the pathogen enters the Zang-Fu organs, it causes mental confusion, palpitations, and fright, producing diseases corresponding to the specific damaged Zang-Fu or meridians. However, *Da Quan* states: Women rely primarily on Ying Blood. Due to excessive blood loss during childbirth, Qi loses its master anchor, leading to cyanosis of the lips, cold flesh, sweating, dizziness, and coma, with life hanging in the balance. This is internal wind generated by extreme deficiency. Treating this with Wind-dispelling herbs would be a mistake. Regardless of the specific symptoms, major warming and tonification should be administered immediately. Use Shiquan Dabu Tang (Complete and Great Tonifying Decoction) with added Fuzi (Aconite Lateral Root). Have someone straighten the patient's body, another person stabilizes the face, opens the mouth, and administers the decoction. If the liquid does not go down, turn the patient to the side to let it drain out, then administer again. If the decoction is hot, administering it cold may facilitate swallowing; after several times, it can be taken, and shortly after, the patient will regain consciousness. This is the method of Xue Lizhai.

Postpartum blood deficiency leading to opisthotonos (rigid arching of the back like a bow) is named Jing syndrome (Spasm). "Jing" means stiffness or rigidity. Sudden severe deficiency of Yin leads to internal heat due to Yin deficiency; extreme heat generates internal wind. Thus, external manifestations resemble wind-pathogen symptoms, but the root cause is actually insufficient Yin and Blood failing to nourish the tendons. This is a sign of extreme deficiency of the Jueyin channel. The treatment should focus on nourishing Yin and tonifying Blood; once Blood is replenished, the deficient wind will naturally extinguish itself.

Postpartum wind-stroke presenting with trismus (lockjaw) occurs because Qi and Blood are deficient, allowing Wind to invade the tendons of the mandible, cheeks, and mouth. The tendons of the Three Yang channels converge at the mandible. Prior to childbirth, damage to the Zang-Fu organs injures the tendons and vessels. When Wind takes advantage of this, the tendons and vessels of the Three Yang channels become relatively weak. Upon exposure to Wind-Cold, they contract severely, resulting in lockjaw. In other cases, extreme deficiency of Heart Qi prevents speech and causes lockjaw. In such instances, within the context of vigorous tonification, herbs that also regulate and unblock Heart Qi should be included.

Postpartum opisthotonos results from the depletion of Qi and Blood, loose interstices (couli), excessive sweating, loss of Shen (Spirit) mastery, and malnourishment of the bones and sinews, presenting as a deficiency pattern. This indicates extreme deficiency of Qi and Blood. Large doses of Ginseng, Cinnamon Twig, [missing character], Atractylodes, Angelica Sinensis, and Rehmannia should be used for warming and nourishing. If there is no response, add Fuzi (Aconite Lateral Root) and double the amount of Ginseng, creating Shenfu Tang (Ginseng and Aconite Decoction). If there is still no response, it is because the medicinal force has not yet reached the target; continue to administer larger doses.
