周身无汗，独头汗出者，乃阴虚阳气上越之象也。若头身俱大汗不止，则恐有亡阳之虑

Chills and fever alternating (alternating chills and fever) result from the mutual rejection of Yin and Yang Qi; treatment should employ Chaihu Siwu Tang Ge Ban Tang (Half-and-Half Decoction of Bupleurum and Four Substances). If alternating chills and fever arise from disharmony of Ying and Wei (Nutritive and Defensive levels), use Guishao Xiongshen Gancao Jiang Tang (Decoction of Angelica, White Peony, Ligusticum, Ginseng, Licorice, and Ginger); if chills and fever resemble malaria and are complicated by blood stasis and food retention, use Shenghua Tang (Life-restoring Decoction) added with Chaihu (Bupleuri Radix), Shanzha (Crataegi Fructus), and Shenqu (Massa Medicata Fermentata). If there is aversion to cold with high fever, use Gengsheng San (San for Revitalization), which consists of Danggui (Angelicae Sinensis Radix), Shudi (Rehmanniae Radix Preparata), Chuanxiong (Ligustici Chuanxiong Rhizoma), Renshen (Ginseng Radix et Rhizoma), Jingjie Sui (Schizonepetae Spica), and Ganjiang (Zingiberis Rhizoma).
[Note] Postpartum disharmony of Yin and Yang leading to alternating chills and fever is suitable for treatment with Chaihu Siwu Tang. If disharmony of Ying and Wei leads to intermittent chills and fever, use Zengsun Siwu Tang (Modified Four Substances Decoction), whose composition includes Danggui (Angelicae Sinensis Radix), Baishao (Paeoniae Radix Alba), Chuanxiong (Ligustici Chuanxiong Rhizoma), Renshen (Ginseng Radix et Rhizoma), Gancao (Glycyrrhizae Radix et Rhizoma), and Ganjiang (Zingiberis Rhizoma). If blood stasis stagnates accompanied by food retention, with chills and fever resembling malaria, use Shenghua Tang (Life-restoring Decoction) added with Chaihu (Bupleuri Radix), Shanzha (Crataegi Fructus), and Shenqu (Massa Medicata Fermentata). If affected by wind-cold pathogens, presenting with aversion to cold and high fever, Gengsheng San (San for Revitalization) is appropriate, composed of Danggui (Angelicae Sinensis Radix), Shudi (Rehmanniae Radix Preparata), Chuanxiong (Ligustici Chuanxiong Rhizoma), Renshen (Ginseng Radix et Rhizoma), Jingjie Sui (Schizonepetae Spica), and Ganjiang (Zingiberis Rhizoma).
Chaihu Siwu Tang (Formula seen in the first volume)
Postpartum Yin deficiency with flourishing Yang may cause slight spontaneous sweating (spontaneous sweating during daytime without exertion, heat, or medication), which is harmless. Head sweating (sweating only on the head) indicates Yin deficiency with Yang floating upward; profuse sweating over the entire body signifies collapse of Yang (exhaustion and escape of Yang Qi).
[Note] Excessive blood loss postpartum leads to Yin deficiency, causing relative Yang excess. Slight spontaneous sweating indicates harmony between Ying and Wei, thus posing no harm. If the body has no sweat but only the head sweats, this is a sign of Yin deficiency with Yang floating upward. If both head and body sweat profusely without stopping, there is a danger of Yang collapse.
Deficient heat steaming upward causes head sweating; treatment should employ Danggui Liu Huang Tang (Six Yellow Decoction of Angelica), where Huangqin (Scutellariae Radix) and Huanglian (Coptidis Rhizoma) are used charred, combined with Danggui (Angelicae Sinensis Radix), Shengdi (Rehmanniae Radix Recens), and Shudi (Rehmanniae Radix Preparata). For severe spontaneous sweating, use Huangqi Tang (Decoction of Astragalus) added with Muli (Ostreae Concha), containing Huangqi (Astragali Radix), Baizhu (Atractylodis Macrocephalae Rhizoma), Fuling (Poria), Gancao (Glycyrrhizae Radix et Rhizoma), Maidong (Ophiopogonis Tuber), Dihuang (Rehmanniae Radix), and Fangfeng (Saposhnikoviae Radix). If profuse sweating persists due to external escape of Yang, large doses of Renshen (Ginseng Radix et Rhizoma) and Fuzi (Aconiti Lateralis Radix Preparata) are required to restore Yang.
[Note] Blood loss postpartum leading to Yin deficiency, with Yang-heat steaming upward, causing sweating on the head up to the neck, is suitable for Danggui Liu Huang Tang (Six Yellow Decoction of Angelica), consisting of Huanglian (Coptidis Rhizoma), Huangqin (Scutellariae Radix), Huangbai (Phellodendri Cortex), Danggui (Angelicae Sinensis Radix), Huangqi (Astragali Radix), Shengdi (Rehmanniae Radix Recens), and Shudi (Rehmanniae Radix Preparata); Huangqin, Huanglian, and Huangbai must be used charred. If spontaneous sweating is excessive, Huangqi Tang (Decoction of Astragalus) is appropriate, composed of Muli Fen (Concha Ostreae Pulvis), Huangqi (Astragali Radix), Baizhu (Atractylodis Macrocephalae Rhizoma), Fuling (Poria), Gancao (Glycyrrhizae Radix et Rhizoma), Maidong (Ophiopogonis Tuber), Shudi (Rehmanniae Radix Preparata), and Fangfeng (Saposhnikoviae Radix). If massive loss of Yin-blood leads to solitary Yang escaping outward with unceasing profuse sweating, only large doses of Renshen (Ginseng Radix et Rhizoma) and Fuzi (Aconiti Lateralis Radix Preparata) can restore Yang.
