睡则汗出，寤则自收也。钱氏曰∶小儿睡而自汗出者，肌肉虚也，止汗散主之。
遍身汗出者，香瓜丸主之，上至胃下至脐，此胃虚也，当补脾，益黄散主之。〔薛〕
自汗属阳虚，盗汗属阴虚，盖阳为卫气，阴为荣血，血之所主心也，所脏肝也，热
搏于心，故液不能内敛而外泄于皮肤，人卧则静而为阴，觉则动而为阳，故曰自汗
属阳，盗汗属阴也，多因心肾不交，水火不能既济，肾虚则闭藏之令失守，故有是
证，宜用六味丸、十全大补汤。血虚内热者，当归六黄汤。心经有热者，导赤散。
肝经虚热者，六味地黄丸。血脱盗汗者，当归补血汤。肝胆风热者，柴胡清肝散。
食积内热者，二陈、枳实、山栀。胃气虚热者，六君子汤及浮麦散。血气俱虚者，
人参养荣汤。余证见自汗，当参览之。〔曾〕有夜睡中而汗自出者，名盗汗。此因

Sweating during sleep, with spontaneous cessation upon waking. Qian Yi stated: When children sweat spontaneously during sleep, it is due to deficiency in the muscles; Zhihan San (Stop Sweat Powder) should be used.
For sweating over the entire body, Xianggua Wan (Melon Pill) is indicated. For sweating extending from the stomach region down to the umbilicus, this indicates Stomach deficiency; the Spleen should be tonified, and Yihuang San (Benefit Yellow Powder) is indicated. [Xue Ji]
Spontaneous sweating belongs to Yang deficiency, while night sweats belong to Yin deficiency. Yang constitutes Wei Qi (Defensive Qi), and Yin constitutes Ying Blood (Nutritive Blood). The Heart governs blood, and the Liver stores blood. Heat pathogen clashing with the Heart causes fluids to fail to remain internalized, leaking externally onto the skin. When lying down to sleep, the body is still and belongs to Yin; upon waking and moving, it belongs to Yang. Thus, spontaneous sweating is attributed to Yang, and night sweats to Yin. This often results from the failure of communication between the Heart and Kidney, where Water and Fire fail to interact harmoniously. Kidney deficiency leads to a loss of the closing and storing function, resulting in these symptoms. Liuwei Wan (Six-Ingredient Rehmannia Pill) and Shiquan Dabu Tang (Ten-Tonifying Decoction) are suitable. For blood deficiency with internal heat, Danggui Liuhuang Tang (Angelica and Honey-Fried Astragalus Decoction) is used. For heat in the Heart Meridian, Daochi San (Guide Out Redness Powder) is indicated. For deficiency heat in the Liver Meridian, Liuwei Dihuang Wan (Six-Ingredient Rehmannia Pill) is used. For night sweats due to blood depletion, Danggui Buxue Tang (Angelica Tonify Blood Decoction) is indicated. For Wind-Heat in the Liver and Gallbladder, Chaihu Qinggan San (Bupleurum Clearing Liver Powder) is used. For internal heat due to food stagnation, Erchen Tang (Two-Aged Decoction), Zhishi (Immature Bitter Orange), and Shanzhi (Gardenia Fruit) are used. For deficiency heat of Stomach Qi, Liujunzi Tang (Six-Gentleman Decoction) and Fumai San (Floating Wheat Powder) are used. For combined Qi and Blood deficiency, Renshen Yangrong Tang (Ginseng Nourishing Grace Decoction) is indicated. For other syndromes, refer to the section on spontaneous sweating for consultation. [Zeng Shirong] Night sweats refer to sweating that occurs spontaneously during sleep. This is caused by Yang deficiency. If prolonged, it leads to emaciation and wasting. It results from insufficient Heart Qi and reckless discharge of body fluids. Fushen Tang (Poria Cocos Decoction) added with Huangqi (Astragalus Root) should be used, taken with a decoction of water, ginger, jujube, and burnt salt.

Huzhang San (Persicaria Polymorpha Powder) treats night sweats due to excess heat. Huzhang (Persicaria Polymorpha Root) decocted in water and administered according to severity, at any time.
[Wang Hai] The son of a Jin Dynasty Langzhong suffered from night sweats for seven years from infancy to childhood, unresponsive to various medicines. I prescribed Liangge San (Cooling Chest Powder) and Sanhuang Wan (Three-Yellow Pill), and the illness resolved in three days. The Kidney corresponds to the five fluids, transforming into five dampnesses. Ministerial Fire forces Kidney Water upward, exploiting Heart deficiency to enter the Hand-Shaoyin Heart Meridian. Heart Fire flares upward into the Lung, bullying the Lung Metal which cannot withstand it. Consequently, the skin pores open, and the Couli (interstices) and Xuanfu (pores) fail to close, leading to sweating. Sweating during sleep is called night sweats because it ceases upon waking. Hence, the classic states: "Night sweats cause aversion to wind." First, use Liangge San to drain the Ministerial Fire in the chest. Once the Ministerial Fire recedes, use Sanhuang Wan to drain Heart Fire to assist Yin, allowing Kidney Water to return to its home organ. The Xuanfu closes, and sweating stops naturally.
[Zeng Shirong] A child had no other disease but sweated profusely like water all over the body during sleep, remaining wet long after waking. This is called accumulation-syndrome night sweats, caused by Cold Spleen. Sanleng San (Sparganium Powder) was used, decocted with water-wrapped ginger, followed by Yihuang San (Benefit Yellow Powder) and Shenling Baizhu San (Ginseng, Poria, and Atractylodes Macrocephala Powder).
Sanleng San (for Pi Accumulation)
Occasional slight cold sweating, hair roots resembling beads, and visible discoloration or pain on the forehead indicate Liver Shock Syndrome. Zhenjing Wan (Settle Shock Pill) or Hubao Longwan (Amber Embracing Dragon Pill) should be used, along with Fushen Tang (Poria Cocos Decoction) added with Mahuanggen (Ephedra Root), decocted in water and taken orally for efficacy.
