According to *Chanbao Baiwen* (Comprehensive Questions on Postpartum Care): Persistent spontaneous sweating after childbirth is caused by deficiency of Yin Qi, while Yang Qi becomes relatively excessive. This results in interior deficiency and exterior excess, with Yang Qi independently dispersing to the exterior, thus causing sweating. Blood belongs to Yin; childbirth injures the blood, which constitutes a deficiency of Yin Qi. Qi belongs to Yang; if Qi is substantial, Yang adds to Yin, causing sweating. If Yin Qi is weak and fails to recover, sweating will persist indefinitely. Generally, both Qi and Blood are deficient after childbirth, leading to profuse sweating. Consequently, exposure to wind may transform into Jing disease (spasm). Even if spasm does not develop, the patient may become weak and fatigued, suffer from shortness of breath, emaciation, dry lips and mouth, and eventually amenorrhea due to the exhaustion of body fluids. (Sweat is the manifestation of Yang Qi. When Yin Qi fails to recover, Yang has no basis to enter Yin, so deficient Yang floats upward to the exterior and transforms into sweat. The world often states that excessive sweating leads to spasm, but overlooks the principle that it is the encounter with wind that triggers the transformation into spasm. Furthermore, cases presenting with shortness of breath and emaciation without spasm indicate the transformation into heat; this must be carefully examined.)

Xue Ji stated: Regarding the aforementioned syndrome, it belongs to dual deficiency of Blood and Qi. One should urgently use Shiquan Dabu Tang (Complete Great Tonifying Decoction). If ineffective, use Shenfu Tang (Ginseng and Aconite Decoction) or similar formulas. If profuse sweating leads to Yang collapse and induces spasm, the aforementioned medicines are even more indicated.

Wang Haicang stated: Head sweating that stops at the neck, with excessive sweating on the forehead, occurs because the forehead is the convergence point of the six Yang meridians. This is caused by steaming from deficient heat. I believe the aforementioned syndrome should be differentiated by location: the left forehead corresponds to the Liver, the right forehead to the Lung, the nose to the Spleen, the chin to the Kidney, and the center of the forehead to the Heart. Practitioners should examine this carefully. (For Yang collapse inducing spasm, using Shiquan Dabu Tang or Shenfu Tang requires careful examination of the etiology before application; one should not blindly adhere to these as standard treatments. Differentiating head sweating by location may seem pedantic, but in clinical practice, detailed investigation is essential because kidney fluids entering the heart transform into sweat; theoretically, this mechanism must be explored.)

A postpartum patient sweated profusely like rain and became unconscious upon hearing slight noises, vomiting any medicine taken orally. I diagnosed this as failure of Spleen Qi. I prepared fine pills from Ginseng powder and Prepared Aconite Root powder, instructing the patient to hold three to five pills in the mouth at a time and swallow them with saliva. The dose was gradually increased to approximately one qian (3 grams), followed by administration of Shenfu Tang, resulting in recovery. (Initially, the brilliance lay in making small pills for low-dose oral absorption; subsequently, large doses of decoction were appropriate.)

Another postpartum patient suffered from persistent night sweats, leading to neglect of sleep and food, extreme mental fatigue, and thirst with desire to drink. I diagnosed this as Blood deficiency with internal heat. I prescribed Danggui Buxue Tang (Angelica Sinensis and Astragalus Decoction) to be taken as tea, and Danggui Liuhuang Tang (Angelica Sinensis and Six Huang Decoction) modified with stir-fried black Scutellariae Radix (Huangqin), Coptidis Rhizoma (Huanglian), and Phellodendri Cortex (Huangbai). (The rationale for stir-frying black for tea substitution is worthy of emulation.) With doubled doses of Ginseng and Schisandrae Fructus (Wuweizi), the condition resolved in two doses.

*Chanbao Baiwen* states: For sudden postpartum fainting, sweating, and loss of recognition, treatment can utilize egg white and Bamboo Sap (Zhuli). (See previous section on Blood Stasis Fainting/Xueyun.)

Xue Ji stated: The aforementioned syndrome belongs to severe deficiency. The primary approach should be to consolidate Yuan Qi (Original Qi). If sweating persists, it will inevitably transform into Rou Jing (soft spasm). (The previous discussion regarding wind-induced spasm from sweating is predominant; otherwise, this would be termed Yang collapse, which necessitates major tonification methods.)

Li Dongyuan stated: In women undergoing delivery or miscarriage with continuous bleeding, symptoms of fainting and closed eyes occur because blood is suddenly lost, causing fire to blaze fiercely. By replenishing the blood, the Spirit (Shen) naturally flourishes. If there is chronic vaginal bleeding, one should tonify and raise Qi. When Yang receives nourishment from Blood, the Shen is peaceful, and vision is restored. I have now established a formula to tonify the Blood of the Hand and Foot Jueyin meridians and simultaneously benefit Yang Qi, named Quansheng Huoxue Tang (Life-Sustaining Blood-Invigorating Decoction).

**Huangqi Tang (Astragalus Decoction)**: Treats persistent postpartum spontaneous sweating.
Ingredients: Huangqi (Astragali Radix, 2 qian), Baizhu (Atractylodis Macrocephalae Rhizoma), Fangfeng (Saposhnikoviae Radix), Shudihuang (Prepared Rehmanniae Radix), Muli (Ostreae Concha, powdered), Baifuling (Poria), Maidong (Ophiopogonis Radix, heart removed), Gancao (Licorice Root, honey-fried, each 0.5 qian).
Preparation: Cut into pieces for two doses. Add one Jujube (Ziziphi Jujubae Fructus). Decoct in water and take orally. (When Huangqi is combined with Fangfeng, its efficacy increases significantly as it facilitates consolidating the Exterior. The ratio of 2 qian Huangqi to 0.5 qian Fangfeng is generally sufficient. Muli is a herb for the Kidney; since kidney fluids enter the heart to form sweat, stopping sweat also requires consolidating the Kidney. Other principles can be understood intuitively.)

**Mahuanggen San (Ephedra Root Powder)**: Treats persistent postpartum spontaneous sweating.
Ingredients: Danggui (Angelicae Sinensis Radix), Huangqi (Astragali Radix, stir-fried), Mahuanggen (Ephedrae Radix et Rhizoma), Muli Fen (Ostreae Concha powder), Renshen (Ginseng Radix et Rhizoma), Gancao (Licorice Root, honey-fried, equal parts).
Preparation: Coarsely crush. Take 4 qian per dose, decoct in water, and take orally. (Mahuang has a potent and light nature, belonging to Yang herbs. Using its root utilizes its "Yin within Yang" property, reflecting the intent of guiding Yang back to its root. One must know that herbal application possesses profound logic.)

**Zhihan San (Stop Sweating Powder)**: Treats persistent postpartum night sweats; applicable to all conditions of excessive sweating.
Ingredients: Muli (Ostreae Concha, powdered), Xiaomai Fu (Triticum aestivum bran, stir-fried until yellow and powdered, equal parts).
Preparation: Mix evenly. Take 2 qian mixed with juice from raw pork, at any time. (Wheat grows during peak Yang and matures during peak Yin, possessing internal Yang and external Yin. Using its bran utilizes its "Yin within Yang." Sweat is the fluid of the Heart, and wheat nourishes the Heart; the bran astringes Heart fluids. Additionally, kidney fluids entering the heart form sweat; pigs are aquatic animals, so using pork juice directs the remedy back to the Kidney. Taking it at any time is because this medicine acts slowly and requires frequent, prolonged administration.)

**Danggui Erhuang Tang (Angelica and Two Huang Decoction)**: Treats postpartum spontaneous and night sweats, weak Stomach Qi, and vomiting preventing intake of other medicines.
Ingredients: Danggui (Angelicae Sinensis Radix), Huangqi (Astragali Radix, each 1 liang), Mahuanggen (Ephedrae Radix et Rhizoma, 0.5 liang).
Preparation: Cut into pieces. Take 3 qian per dose, decoct in water, and take orally. (Mahuanggen guides Yang back to Yin, following its nature; Baishao (Paeoniae Radix Alba) suppresses Liver Qi and astringes Yin, utilizing its sour taste. Danggui and Huangqi are variants of the Blood-Tonifying Decoction. In my opinion, establishing this formula with Huangqi as the Sovereign herb aligns with orthodoxy. "Yang adding to Yin is called sweat." Using herbs that add Yin to Yang to treat this reverses the pathology, stopping the sweat. This is the general idea of the prescription, known as treating reversal with orthodox methods.)

An alternative formula replaces Mahuanggen with Baishao.

**Danggui Liuhuang Tang (Angelica and Six Huang Decoction)**: Treats Blood and Qi deficiency with heat, and persistent night sweats.
Ingredients: Danggui (Angelicae Sinensis Radix), Huangqi (Astragali Radix, stir-fried), Shudihuang (Prepared Rehmanniae Radix, each 2 qian), Shengdihuang (Rehmanniae Radix), Huangbai (Phellodendri Cortex, stir-fried black), Huangqin (Scutellariae Radix, stir-fried black), Huanglian (Coptidis Rhizoma, stir-fried black, each 1 qian).
Preparation: Decoct in water. If ineffective, add Renshen (Ginseng Radix et Rhizoma) and Baizhu (Atractylodis Macrocephalae Rhizoma). For insufficient Heart Blood, add Suanzaoren (Ziziphi Spinosae Semen).

**Renshen Tang (Ginseng Decoction)**: Treats various postpartum deficiencies, fever, and night sweats.
Ingredients: Renshen (Ginseng Radix et Rhizoma), Danggui (Angelicae Sinensis Radix, equal parts).
Preparation: Powder the ingredients. Take one pig kidney, remove the fascia, and slice thinly. Decoct with 3 sheng of water, Banmi (Glutinosa Oryzae Semen, half he), and two stalks of Congbai (Allii Fistulosi Bulbus) until the rice is cooked. Strain to obtain one zhan of clear liquid. Add 2 qian of the powder, decoct until 0.8 zhan remains, and take warm at any time. (This formula focuses on Qi and Blood, with the meridian-guiding妙处 (wonder) lying in the pig kidney. However, Banmi nourishes Yin, and Congbai disperses. Why use them? Sweat is not counted by odd numbers, and downward-moving drugs are paired. Thus, Congbai is not used alone but cooked with rice, suggesting an intent to guide Yin. Ah, this contains deep thought.)

**Shenfu Tang (Ginseng and Aconite Decoction)**: Treats Yang Qi deficiency and cold, spontaneous sweating, aversion to cold, cold limbs, loose stools, umbilical/abdominal pain, hiccups/anorexia, or profuse sweating inducing spasm.
Ingredients: Renshen (Ginseng Radix et Rhizoma, 1 liang), Fuzi (Prepared Aconiti Lateralis Radix, processed, 5 qian).
Preparation: Prepare as one dose. Add Ginger (Shengjiang) and Jujube, decoct in water, and take slowly. (This is an supreme emergency rescue formula, the method of returning Yang and restoring the root. It is suitable only for cases of cold limbs and sweating like rain.)

**Qifu Tang (Astragalus and Aconite Decoction)**: Treats Yang Qi collapse, aversion to cold, spontaneous sweating, locked jaw with phlegm surging, cold limbs, vomiting/diarrhea with abdominal pain, inability to eat, and all deficiency-cold syndromes.
Ingredients: Huangqi (Astragali Radix, 1 liang), Fuzi (Prepared Aconiti Lateralis Radix, processed, 5 qian).
Preparation: Prepare as one dose. Add Ginger and Jujube, decoct in water, and take orally. If ineffective, double the dose of Fuzai to ensure complete relief. (One formula uses Renshen, the other Huangqi; one consolidates Exterior Qi, the other tonifies Interior Qi. They are distinct. Practitioners must examine the interior and exterior to determine the appropriate application, approaching the Dao of medicine. As the saying goes, "Seek what exists, seek what does not exist," which is a profound statement.)

**Qianjin Fang (Prescription from the Thousand Gold Formulas)**: Treats postpartum wind-deficiency sweating, scanty urination, limb contracture, and difficulty in flexion and extension.
Ingredients: Gancao (Licorice Root, honey-fried, 1 liang), Fuzi (Prepared Aconiti Lateralis Radix, processed), Guixin (Cinnamomi Cortex), Shaoyao (Paeoniae Radix, stir-fried, each 1.5 liang).
Preparation: Coarsely crush. Take 3 qian per dose. Add four slices of Ginger and one Jujube. Decoct in water. Avoid pork, cold water, and raw scallions. (Using Guizhi Tang to treat wind and adding Fuzi to treat deficiency creates Guizhi Jia Fuzi Tang (Guizhi Decoction plus Aconite), a method of Zhang Zhongjing. Because of limb contracture, this formula is used; otherwise, why would it be chosen?)

**Quansheng Huoxue Tang (Life-Sustaining Blood-Invigorating Decoction)**: Treats postpartum fainting, fever, spontaneous and night sweats, blurred vision, limb weakness, dry mouth, dizziness, and unsteady gait.
Ingredients: Shengma (Cimicifugae Rhizoma), Shaoyao (Paeoniae Radix, stir-fried, each 3 qian), Danggui (Angelicae Sinensis Radix), Chaihu (Bupleuri Radix), Fangfeng (Saposhnikoviae Radix), Qianghuo (Notopterygii Rhizoma et Radix), Duhuo (Angelicae Pubescentis Radix), Gegen (Puerariae Lobatae Radix), Gancao (Licorice Root, stir-fried, each 1 qian), Chuanxiong (Ligustici Chuanxiong Rhizoma), Gaoben (Ligustici Wallichii Rhizoma, each 1.5 qian), Shengdihuang (Rehmanniae Radix), Shudihuang (Prepared Rehmanniae Radix, each 1 qian), Xixin (Asari Radix et Rhizoma), Manjingzi (Viticis Semen, each 0.5 qian), Honghua (Carthami Flos, 0.3 qian).
Preparation: Coarsely crush. Take 5 qian per dose, decoct in water, and take hot. (Who would believe using ascending wind-dispelling herbs to treat spontaneous and night sweats? However, Li Dongyuan advocates this decoction to benefit Yang. The *Suwen* states: "Yin rises rapidly following Yang." If Yin does not follow Yang, Yang disperses externally, causing excessive sweating. Shengma and Gegen ascend Yangming Qi; Chaihu and Fangfeng ascend Jueyin Qi; Qianghuo and Gaoben ascend Taiyang Qi on the back; Xixin and Duhuo ascend Shaoyin Qi at the front; Manjingzi cools blood in various meridians; Gancao harmonizes Yang Qi; Siwu Tang nourishes Blood in Yin meridians; Honghua invigorates Blood in Yang collaterals. Since it ascends without astringing, it cannot store Yin, hence Baishao is used as Sovereign. Ascending too much fails to benefit Qi, hence Gancao is used as Assistant. Although stated thus, who dares to use it? Observing the symptoms of fainting, fever, dry mouth, dizziness, and unsteady gait, these are pathogens lodging in the meridians. Due to pathogenic lodging and disharmony between Yin and Yang, spontaneous and night sweats occur. This formula harmonizes, allowing external pathogens to enter and internal pathogens to exit, unblocking meridians, scattering pathogens, harmonizing Yin and Yang, and enabling the function of sinews and bones. Would the aforementioned symptoms remain?)
