（附：头汗、心汗、汗斑）
经典记载：汗是心的津液，阳气作用于阴气便形成汗。自汗是指没有特定时间而自然出汗，活动后更加严重，属于阳气虚弱。阳实证则无汗。人体依靠卫气来固护体表，卫气虚弱则导致自汗淋漓、时时渗出，应当补益阳气以助卫气，腠理（皮肤纹理及毛孔）才能致密。也有因心火上炎，脾湿不降，如同湿热蒸腾化为雨水，所以汗出较多，适宜采用清热利湿的方法治疗。脉象微涩而濡，主虚汗。

(Attached: Head Sweat, Heart Sweat, Sweat Spots)
The Classics state: Sweat is the fluid of the Heart; when Yang acts upon Yin, it is called sweat. Spontaneous sweating refers to sweating without a specific time, which worsens with movement, and belongs to deficiency of Yang Qi. Excess of Yang results in no sweat. The human body relies on Wei Qi (Defensive Qi) to secure the exterior. When Wei Qi is weak, spontaneous sweating occurs with continuous leakage, requiring supplementation of Yang to assist Wei Qi, so that the Cou Li (skin texture and pores) may become solid. There are also cases where Heart Fire flares upward and Spleen Dampness fails to descend, similar to heat and dampness steaming into rain, thus causing profuse sweating; this should be treated with clearing and draining methods. A pulse that is faint, choppy, and soggy indicates deficiency sweating.
Main Formula: Ren Shen (Ginseng Radix), Huang Qi (Astragali Radix, honey-fried), Bai Zhu (Atractylodis Rhizoma), Fu Ling (Poria), Dang Gui (Angelicae Sinensis Radix), Huang Lian (Coptidis Rhizoma), Bai Shao (Paeoniae Radix Alba), Zao Ren (Ziziphi Spinosae Semen, fried and crushed), Mu Li (Ostreae Concha, calcined). Each 1 qian; Gui Zhi (Cinnamomi Ramulus), 7 fen; Gan Cao (Glycyrrhizae Radix et Rhizoma, honey-fried), 5 fen. To the above formula, add Fu Xiao Mai (Tritici Levis Fructus) a pinch, Wu Mei (Mume Fructus) one piece, Da Zao (Jujubae Fructus) two pieces. Decoct in water and take orally.
If sweating does not stop, add Wu Wei Zi (Schisandrae Chinensis Fructus), Rou Gui (Cinnamomi Cortex), Ma Huang Gen (Ephedrae Radix et Rhizoma); after decoction, mix in Long Gu (Fossilia Ossis Mastodi) powder. For deficient persons, add Shan Zhu Yu (Corni Fructus) and Rong Rui (Cynomorii Herba). For excessive dampness, add Ze Xie (Alismatis Rhizoma), Fu Ling (Poria), Fang Feng (Saposhnikoviae Radix), and Bai Zhi (Angelicae Dahuricae Radix). For Yang deficiency, add Zhi Fu Zi (Aconiti Lateralis Radix Praeparata). For excess fire, double the amount of Huang Lian (Coptidis Rhizoma). For extreme heat, decoct Liang Ge San separately (see Formula under Fire section). If sweating is extremely severe and unceasing, use Ban Sheng of Fu Xiao Mai (Tritici Levis Fructus), decoct to obtain juice, discard the grain, and use this juice to decoct the medicine. For concurrent phlegm abundance or Qi stagnation, modify according to symptoms.
