Li stated: Postpartum exterior contraction of wind-cold occurs due to getting out of bed too early, or being exposed to wind when changing clothes, allowing cold to enter the lower part. This causes chills and fever resembling malaria, and unremitting headache (The symptoms of chills and fever resembling malaria and unremitting headache cover several of the aforementioned conditions; formulas should be selected with discretion). For blood deficiency, use Xionggui Tang (Cnidium and Angelica Decoction) added with Renshen (Ginseng), Zisu (Perilla Leaf), and Gange (Kudzu Root); for qi and blood deficiency, use Buxu Tang (Deficiency-Supplementing Decoction) added with Chenpi (Tangerine Peel) and Ganjiang (Dried Ginger); for severe chills and fever, use Shuliao Wuji San (Five Accumulations Powder with Cooked Ingredients); for persistent fever, Huanglong Tang (Yellow Dragon Decoction) is the primary treatment. If the constitution is robust, presenting with fever, aversion to cold, as well as malaria or dysentery, use Xiaochaihu Tang (Minor Bupleurum Decoction) combined with Sijunzi Tang (Four Gentlemen Decoction) and Siwu Tang (Four Substance Decoction), added with Huangqin (Scutellaria Root), named Sanfen San (Three-Parts Powder). It is crucial not to treat this using methods for Shanghan (Cold Damage). If too many hot-natured medicines are mistakenly taken, leading to prominent heat syndromes and subsequent constipation after a long time, Chaihu Poyu Tang (Bupleurum Stasis-Breaking Decoction) may be used, or Siwu Tang added with Dahuang (Rhubarb Root) and Mangxiao (Mirabilite) for temporary use, followed by regulation and supplementation.

Liangfang states: Postpartum exterior contraction of wind-cold presents with fever, headache, and body pain. Although it resembles Shanghan or seasonal epidemics, even if Mahuang (Ephedra Herb) is needed for sweating, it must not be used lightly (This is a critical point). If injury from cold occurs due to early rising and labor, one will feel chilly aversion to cold, mild fever, and pain in the head, neck, shoulders, back, and joints, which resolves after seven to eight days. If the stool is hard, vomiting occurs, and eating is impossible, use Xiaochaihu Tang added with Shengjiang (Fresh Ginger) and Dihuang (Rehmannia Root). (Adding Dihuang for vomiting should be used with discretion).

Wu stated: In the immediate postpartum period, contracting Shanghan should not lead to hasty sweating therapy. Fever can result from exertion during childbirth, excessive blood loss, retention of lochia, milk engorgement on the third day, or early labor and food stagnation. All these cause fever resembling Shanghan. The key lies in careful and detailed differentiation; one must not rashly induce sweating. Generally, postpartum blood is empty (a major deficiency leading to variations). If sweating is induced, it may cause twitching of sinews and muscles, or depression and dizziness with coma and loss of consciousness, or convulsive movements that are unstable, or constipation and difficulty defecating. The harm is not slight; thorough examination is essential. For any fever, initially administer Siwu Tang (Four Substance Decoction), with Chuanxiong (Szechwan Lovage Rhizome) and Danggui (Angelica Sinensis) as the sovereign herbs in the largest doses. Baishao (White Peony Root) must be stir-fried, and Jiuhuang (Wine-processed Rehmannia Root) serves as an assistant herb. If fever persists, adding Ruanmiao Chaihu (Soft-stemmed Bupleurum Root), Renshen (Ginseng), and Paoganjiang (Stir-fried Dried Ginger) is most effective. The pungent and hot nature of Ganjiang guides blood-invigorating herbs into the blood level and qi-regulating herbs into the qi level. Moreover, it eliminates lochia and nourishes new blood, following the principle of "yang generates yin." Treating heat with heat aligns deeply with the principles of Neijing (Inner Canon). I have used it with miraculous efficacy, so I record it to encourage others. If lochia is not fully expelled, Yimu Wan (Motherwort Pill) and Heishen San (Black Divine Powder) must be used concurrently. If there is stomach deficiency and poor appetite, Baizhu (Atractylodes Macrocephala Rhizome) and Fuling (Poria) must be added. If there is phlegm, vomiting, and counterflow, Chenpi (Tangerine Peel) and Banxia (Pinellia Tuber) must be added. The treatment examples for the other six meridians remain the same, but Siwu Tang must be included as the main component in all prescriptions, as this is the essential method for nourishing blood and securing the root.

Daquan states: Whenever postpartum fever, headache, and body pain occur, do not immediately treat them as a common cold. These cases are mostly due to blood deficiency or obstruction by stagnant blood. Mild and harmonizing formulas should be administered, which will surely be effective, such as Yulu San (Jade Dew Powder) or Siwu Tang added with Beichaihu (Northern Bupleurum Root) in equal parts (Equal-part dosage is a prudent adherence to rules). Many cases fail to respond if Xiaochaihu Tang or Zhuyegao Tang (Bamboo Leaf and Ophiopogon Decoction) are used directly.

Postpartum wind-stroke lasting dozens of days without resolution, with mild headache, aversion to cold, intermittent fever, chest oppression, dry retching, and profuse sweating, is merely the Yangdan syndrome. Yangdan Tang (Yangdan Decoction) may be given. (This is Guizhi Tang (Cinnamon Twig Decoction), see Shanghan Lun. Zhang Zhongjing's term "wind-stroke" refers to what modern people call "wind-cold"; Yangdan Tang follows Zhang Zhongjing's formula.)

Jiawei Xionggui Tang (Modified Cnidium and Angelica Decoction): Treats postpartum qi and blood deficiency with exterior contraction of wind-cold, headache, aversion to cold, and high fever.
Danggui (Angelica Sinensis Root), Chuanxiong (Szechwan Lovage Rhizome) (each 2 qian), Renshen (Ginseng), Zisu (Perilla Leaf), Gange (Kudzu Root) (each 1 qian).
Crush the herbs, add three slices of Shengjiang (Fresh Ginger), decoct in water, and take orally.

Zhuye Tang (Bamboo Leaf Decoction): Treats postpartum wind-stroke with fever, flushed face, wheezing, and headache.
Zhuye (Bamboo Leaf) (one handful), Gegen (Kudzu Root) (3 liang), Fangfeng (Saposhnikovia Root), Jiegeng (Platycodon Root), Guizhi (Cinnamon Twig), Renshen (Ginseng), Gancao (Licorice Root, honey-fried) (each 1 liang).
Chop the herbs. Take 5 qian per dose, with one jujube and five slices of ginger. Decoct in 1.5 sheng of water until 1 sheng remains, strain, and take warm. Cover warmly to induce sweating. If there is stiffness in the head and neck, use Dafuzi (Aconite Lateral Root) 5 fen; decoct the medicine, skim off the foam, and add Banxia (Pinellia Tuber) 1 qian if vomiting occurs. (Using Zhuye and Gegen as sovereign herbs addresses the flushed face and wheezing. However, avoiding blood-invigorating herbs and using Renshen and Guizhi targets wind-stroke. While this is the general principle, application requires discretion. Dafuzi must also be used skillfully.)
