睡眠中出汗的，称为盗汗。又名“一寝汗”。无论坐着还是躺着都出汗的，称为自汗。因伤风、伤暑、伤寒、伤湿或痰嗽等引起的自汗，各自记载在本章相关门类中。那些没有疾病却经常自汗出，以及病后多汗的情况，都属于表虚证，是胃气不固、营血外泄所致。适宜使用黄耆建中汤，加入少许浮小麦煎服；或者煎服黄耆六一汤，或者服用玉屏风散。如果身体温度如常但出汗发冷，或者身体寒冷且汗也发冷，没有其他病症，均属于本证。
如果有痰证导致冷汗自出的，适宜使用七气汤。此方已记载在第二百四十九卷“肾逆散”之下。如果是气机不顺导致自汗不止，需要调理气机，使营卫调和。可用小建中汤加木香。
对于病后多汗，服用正元饮及其他重补药剂无效的情况，适宜使用八珍散。还有身体其他部位无汗，唯独心口（膻中穴区域）一片有汗的情况，思虑过多则汗也增多，病位在于用心过度，适宜滋养心血。用药只需单一方向，仍以艾叶汤调服茯苓末，名为“心汗”。用青桑第二片叶子焙干研成末，空腹时用米饮汤送服，最擅长治疗盗汗。
如果是阴部出汗，只用密陀僧和蛇床子研成末，扑撒患处即可立即停止。
如果服药后汗仍不止，用小建中汤加熟附子一钱（不去皮），或者使用正元饮，同时仍以温粉扑撒患处。大汗不止的，宜在诸药中加入一分牡蛎粉，并吞服朱砂丹，或者茸朱丹。
经常自汗出，经年累月的，多用黑锡丹。久病及大病刚痊愈后出汗的，也可以使用此药。如果不适宜热性补益，必须交通阴阳，自然痊愈，应当以灵砂丹为主治。以上这些方法，都是专门针对单纯止汗而设的，并非指伴有其他兼夹病症的情况。
如果服用各种药物，想要止汗并巩固表里，都没有效果，药性越热汗越收不住，可以只调理心血。因为汗是心的体液，心无所养，不能摄血，所以溢出成为汗。适宜使用大黄汤（注：此处原文可能有误，通常止汗不用大黄，或为特定方名，依原文直译），加炒酸枣仁半钱。有微热的，再加炒石斛半钱，同时服用灵砂丹。
出汗像胶一样粘稠，像珠子一样凝结，以及淋漓如雨，擦拭不及的，难以治疗。漏风症的多汗，出自《中风证》中的“中门”证候。
应该出汗多而导致虚热的，不应当拘泥于清热，适宜使用收敛的药剂。出汗并且伴有邪热的，其人如果不口渴，小柴胡汤加桂枝半钱是最好的。
治疗心虚多汗且不睡觉，取猪心一个，剖开带血，用人参二两、当归二两，装入猪心中煮熟，去掉这两味药，只吃猪心。不满三四天，其病即愈。
Those who sweat while sleeping soundly are said to have *Dao Han* (Gibbering Sweat / Night Sweats). It is also known as "Yi Qin Han" (Sweat during one sleep). Those who sweat regardless of whether they are sitting or lying down are said to have *Zi Han* (Spontaneous Sweat). Spontaneous sweats caused by wind-cold, summerheat, cold-dampness, or phlegm-cough are recorded in their respective sections. Cases where there is no disease but constant spontaneous sweating, or excessive sweating after an illness, all belong to *Biao Xu* (Deficiency of the Exterior), due to unstable Stomach Qi and leakage of Ying Blood (Nutritive Blood). Huangqi Jianzhong Tang (Astragalus Decoction for Building the Middle) with a little Fumai (Floating Wheat) added for decoction is suitable. Alternatively, Huangqi Liuyin San (Astragalus Six-to-One Powder) may be decocted, or Yupingfeng San (Jade Windscreen Powder) may be taken. If the body temperature is normal but the sweat feels cold, or if the body is cold and the sweat is also cold, with no other diseases, these all belong to this syndrome.
For cases of spontaneous cold sweat accompanied by phlegm syndromes, Qi Qi Tang (Seven-Qi Decoction) is suitable. This formula is already recorded under Shen Ni San (Kidney Rebellious Qi Powder) on page 249. For spontaneous sweat that does not stop due to stagnant Qi, it is necessary to regulate Qi to harmonize Ying and Wei (Defensive) energies. Xiao Jianzhong Tang (Minor Decoction for Building the Middle) with Muxiang (Aucklandia Root) added is appropriate.
For excessive sweating after an illness, if Zhengyuan Yin (Upright Origin Decoction) and other heavy tonifying agents fail, Bazhen San (Eight-Treasure Powder) is suitable. In cases where there is no sweat elsewhere on the body, but only a patch of sweat at the Xin Kong (Heart Orifice / Sternum area), and sweating increases with excessive mental exertion, the pathology lies in overuse of the mind. It is suitable to nourish Heart Blood. Medication should follow a single principle, using Aitang (Mugwort Decoction) to mix and administer Fuling Mo (Poria Powder), named "Xin Han" (Heart Sweat). Qing Sang Di Er Ye (the second leaf of Green Mulberry) dried by roasting and ground into powder, taken with Mi Yin Tang (Rice Drink) on an empty stomach, is most effective for treating night sweats.
For Yin Han (sweating in the genital area), mixing Mituoseng (Lead Monoxide) and Shechuangzi (Cnidium Fruit) into a powder and dusting it on the area will stop it immediately.
If sweating persists despite medication, add Shu Fuzi (Prepared Aconite Lateral Root, skin left on) to Xiao Jianzhong Tang. Alternatively, use Zhengyuan Yin, and simultaneously apply Wen Fen (Warm Powder) to the body. For profuse sweating that does not stop, add one part Musli Fen (Oyster Shell Powder) to various medicines, and swallow Zhusha Dan (Cinnabar Pill) or Rongzhu Dan (Velvet Cinnabar Pill).
For chronic spontaneous sweating lasting years, Heixi Dan (Black Tin Pill) is frequently used. It can also be used for sweating after prolonged illness or shortly after recovery from severe illness. If hot tonification is unsuitable, Yin and Yang must be made to interact and support each other, leading to natural recovery; Lingsha Dan (Alchemical Mercury Pill) should be the primary treatment. All the above methods are designed specifically to stop sweating without addressing other diseases, and do not apply to cases with concurrent pathologies.
If taking various medicines to stop sweating and consolidate the exterior and interior yields no effect, and hotter medicines cause even more uncontrolled sweating, one should only regulate Heart Blood. Since sweat is the fluid of the Heart, if the Heart lacks nourishment and cannot control blood, it overflows as sweat. Dahuang Tang (Rhubarb Decoction) with Chao Suanzaoren (Stir-fried Sour Jujube Seed) added is suitable. For those with slight heat, add Chao Shihu (Stir-fried Dendrobium Stem), and concurrently administer Lingsha Dan.
Sweat that is sticky like glue, coagulating like beads, or pouring down like rain, too fast to wipe away, is difficult to treat. Profuse sweating in Lou Feng (Leaking Wind) comes from the Zhong Men (Central Gate) syndrome in Stroke Syndromes.
For cases where excessive sweating leads to deficient heat, one should not stick strictly to clearing heat; instead, astringent formulas are suitable. For sweating accompanied by pathogenic heat, if the patient is not thirsty, Xiaochaihu Tang (Minor Bupleurum Decoction) with Ban Qian (Half a Qian) of Guizhi (Cinnamon Twig) added is best.
To treat Heart deficiency causing excessive sweating and insomnia: Take one pig heart, cut open keeping the blood, insert Ren Shen (Ginseng Root) two liang and Dang Gui (Angelica Sinensis Root) two liang into the heart, boil until cooked. Remove the herbs, and eat only the pig heart. Within three to four days, the illness will heal.
