自汗属阳有虚实，或因胃热或表虚，睡中盗汗为阴弱，心虚血热随证医。
【注】汗乃人之津液，存于阳者为津，存于阴者为液，发泄于外者为汗。若汗无故而
出者，乃因阴阳偏胜也。如小儿无因而汗自出者，谓之自汗。自汗属阳，有虚实之别。虚
者汗出翕翕，发热恶寒，乃表虚也；汗出蒸蒸，发热不恶寒，乃里热也，表虚者，法当
固表；里实者，法当攻热。又有睡则汗出，觉则汗止，谓之盗汗。盗汗主阴虚，然当分心
虚不固，心火伤阴也。心虚当补心，心热当凉血。治者宜详辨之，庶无差谬。
表虚自汗玉屏风，甚者桂枝加附从，里实自汗用白虎，便秘调胃承气攻。
【注】表虚 自汗，玉屏风散主之。若恶寒冷，阳气虚也，桂枝汤加附子固之。阳
明里实，蒸蒸自汗，用白虎汤清之。便秘者，以调胃承气汤攻之。

Self-sweating belongs to Yang syndromes and is divided into deficiency (Xu) and excess (Shi) types. It may be caused by stomach heat or exterior deficiency (Wei Qi deficiency). Night sweating during sleep is attributed to Yin deficiency, often resulting from Heart Qi deficiency and Heat in the Blood level; treatment should be based on syndrome differentiation.
[Note] Sweat is a part of body fluids. Those existing at the exterior Yang level are called "Jin" (thin fluid), those existing at the interior Yin level are called "Ye" (thick fluid), and those excreted to the outside are called "Han" (sweat). If sweat flows out without cause, it is due to an imbalance and excess of Yin or Yang. For example, when children sweat spontaneously without obvious cause, it is called self-sweating. Self-sweating belongs to Yang syndromes and has deficiency and excess distinctions. Deficiency type presents with mild warmth upon sweating (Xi Xi fever), accompanied by fever and aversion to cold, indicating exterior deficiency; Excess type presents with steaming heat upon sweating (Zheng Zheng fever), with fever but no aversion to cold, indicating interior heat. For exterior deficiency, the treatment method is to consolidate the exterior; for interior excess-heat, the treatment method is to purge interior heat. Another condition is sweating during sleep that stops upon waking, known as night sweating (Dao Han). Night sweating primarily indicates Yin deficiency, but one must distinguish between Heart Qi deficiency failing to secure the exterior and Heart Fire injuring Yin. Heart Qi deficiency requires tonifying the Heart, while Heart Fire requires cooling the blood and clearing heat. Practitioners should differentiate carefully to avoid errors.
For self-sweating due to exterior deficiency, use Yu Ping Feng San (Jade Windscreen Powder); if severe, add Fu Zi (Prepared Aconite Root) to Gui Zhi Tang (Cinnamon Twig Decoction). For self-sweating due to interior excess-heat, use Bai Hu Tang (White Tiger Decoction); if accompanied by constipation, use Tiao Wei Cheng Qi Tang (Regulate the Stomach and Direct Downward Decoction) to purge.
[Note] Self-sweating due to exterior deficiency is primarily treated with Yu Ping Feng San. If there is severe aversion to cold, it indicates Yang Qi deficiency, and Gui Zhi Tang (Cinnamon Twig Decoction) with added Fu Zi (Prepared Aconite Root) can be used to secure Yang Qi. Yangming interior excess-heat presents with steaming self-sweating, treated with Bai Hu Tang (White Tiger Decoction) to clear heat. If accompanied by constipation, Tiao Wei Cheng Qi Tang (Regulate the Stomach and Direct Downward Decoction) is used to purge.

Heart Qi deficiency leading to night sweating often involves frequent dreaming and fright; taking Suan Zao Ren Tang (Ziziphus Seed Decoction) brings calmness. Heart Fire injuring Yin inevitably causes irritability and heat; taking Dang Gui Liu Huang Tang (Angelica Hexa-Huang Decoction) achieves efficacy.
[Note] Night sweating has two types, divided into deficiency and excess. Heart Qi deficiency means Yin Qi fails to gather; sleeping involves much fright, primarily treated with Suan Zao Ren Tang (Ziziphus Seed Decoction). Heart heat means fire injures Yin; the body experiences much irritability and heat, primarily treated with Dang Gui Liu Huang Tang (Angelica Hexa-Huang Decoction).
