凡汗出不治之证有六∶一、汗出而喘甚者,不治。二、汗出而脉脱者,不治。三、汗出
而身痛甚者,不治。四、汗出发润至颠者,不治。五、汗出如油者,不治。六、汗出如珠者
,不治。凡见此类,不得妄为用药。
一、阳证自汗或盗汗者,但察其脉证有火,或夜热烦渴,或便热喜冷之类,皆阳盛阴虚
也,宜当归六黄汤为第一,保阴煎亦妙。其或阴分虽有微火而不甚者,宜一阴煎、或加减一
阴煎之类主之。其有心火不宁,烦躁出汗者,宜朱砂安神丸、天王补心丹、生脉散之类主之
。又有本非阴虚,止因内火熏蒸,血热而多汗者,宜正气汤,或黄芩芍药汤、清化饮之类主
之。
一、阴证自汗或盗汗者,但察其内无火邪,又无火脉,便是气虚阴证,皆不可妄用凉药
以败阳气。若止因气虚而火未衰者,宜三阴煎、参归汤、人参建中汤之类主之。若睡中盗汗
而无火者,宜参苓散、独参汤主之。若阳气俱虚者,宜参附汤、大建中汤之类主之。若气虚
火衰之甚者,宜大补元煎、六味回阳饮之类主之。
一、卫气不固,腠理不密而易汗者,是亦阴证之属,宜黄 六一汤、玉屏风散、 附汤
之类主之。
一、诸病误治,有不当汗而妄汗,或虽当汗而汗之太过者,皆汗多亡阳之证,是亦阴证
之属,当察其虚之微甚。微虚者,宜三阴煎、五阴煎、独参汤之类主之;大虚者,非大补元
煎、六味回阳饮之类不可。
一、湿气乘脾者,亦能作汗。凡证有身重困倦,而脉见缓大,声音如从瓮中出者,多属
湿证。若热湿胜者,但去其火而湿自清,宜用前阳证之法。寒湿胜者,但助其火而湿自退,
宜用前阴证之法。或用玉屏风散、四君子汤、五君子煎之类以健脾土之气,则湿去而汗自收
。
一、收汗止汗之剂,如麻黄根、浮小麦、乌梅、北五味、小黑豆、龙骨、牡蛎之属,皆
可随宜择用。一曰∶黄 得防风而力愈大。一曰∶官桂最能实表。一、凡汗出太多不能收者
,速宜用五倍子为末,以唾津调填脐中,外用帕帛缚定,过宿即止;或用何首乌为末,填脐
缚之,亦止。
一、小儿盗汗,虽是常事,在东垣诸公,皆曰不必治之。盖由血气未足也。然汗之太多
者,终属气分之虚。余于儿辈见汗之甚者,每以人参一钱许,煎汤与服,当夜即止。正恐他
日之强弱未必不由乎此,所以培补之功原不可少。
一、病后多汗,若伤寒,若疟疾。凡系外感寒邪,汗出热退而有汗不即止者,此以表邪
初解,必由腠理卫气开泄,其汗宜然,即数日旬日亦自无妨,俟卫气渐实,汗必自止,无足
虑也。若其他杂证,本非外感之解,而有自汗盗汗者,乃非所宜,不容不治。
There are six types of sweating conditions that are considered untreatable: First, sweating accompanied by severe asthma (wheezing/shortness of breath) is untreatable. Second, sweating accompanied by pulse disappearance (pulselessness) is untreatable. Third, sweating accompanied by severe body pain is untreatable. Fourth, sweating so profuse that the hair becomes moist up to the vertex is untreatable. Fifth, sweating resembling oil is untreatable. Sixth, sweating resembling pearls (bead-like droplets) is untreatable. In any case where these signs appear, medication should not be administered recklessly.
First type: Spontaneous sweating or night sweats in Yang syndromes. If the pulse and symptoms indicate the presence of Fire pathogen, or if there is nocturnal fever with irritability and thirst, or hot stools with a preference for cold drinks, these all indicate Excess of Yang and Deficiency of Yin. The first choice is Danggui Liuhuang Tang (Angelica Hexapartite Decoction), and Baoyin Jian (Preserve Yin Decoction) is also excellent. If there is slight Fire in the Yin aspect but not severe, Yiyin Jian (One Yin Decoction) or Jiajian Yiyin Jian (Modified One Yin Decoction) should be used. If the cause is unsettled Heart Fire leading to irritability and sweating, Zhusha Anshen Wan (Cinnabar Calming the Spirit Pill), Tianwang Buxin Dan (Emperor of Heaven Tonifying the Heart Pill), or Shengmai San (Generate Pulse Powder) should be used. For cases not originally due to Yin Deficiency, but rather due to internal Fire steaming causing Blood Heat and excessive sweating, Zhengqi Tang (Righteous Qi Decoction), Huangqin Shaoyao Tang (Scutellaria and Peony Decoction), or Qinghua Yin (Clearing Transformation Decoction) should be used.
Second type: Spontaneous sweating or night sweats in Yin syndromes. If observation shows no Fire pathogen internally and no Fire pulse, it is a Qi Deficiency Yin syndrome. Cold medicines must not be used recklessly to damage Yang Qi. If it is merely Qi Deficiency without significant decline of Fire, Sanyin Jian (Three Yin Decoction), Shen Gui Tang (Ginseng and Angelica Decoction), or Renshen Jianzhong Tang (Ginsense Replenishing the Middle Decoction) should be used. For night sweats during sleep without Fire, Shenling San (Ginseng and Poria Powder) or Dushen Tang (Single Ginseng Decoction) should be used. If both Qi and Yang are deficient, Shenfu Tang (Ginseng and Aconite Decoction) or Da Jianzhong Tang (Great Replenishing the Middle Decoction) should be used. For severe Qi Deficiency and declining Fire, Dabu Yuan Jian (Great Tonifying the Origin Decoction) or Liuwei Huiyang Yin (Six-Ingredient Restoring Yang Infusion) should be used.
Third type: Unsecured Wei Qi (Defensive Qi) and loose Couli (pores/skin texture) leading to easy sweating belong to the category of Yin syndromes. Huangqi Liuyi Tang (Astragalus Six-One Decoction), Yupingfeng San (Jade Windscreen Powder), or Fuzi Tang (Aconite Decoction) should be used.
Fourth type: Various diseases treated incorrectly, such as inducing sweating when not indicated, or sweating excessively when indicated, result in sweating-induced loss of Yang Qi. This also belongs to Yin syndromes. One must assess the degree of deficiency. For mild deficiency, Sanyin Jian, Wuyin Jian (Five Yin Decoction), or Dushen Tang should be used; for severe deficiency, only Dabu Yuan Jian or Liuwei Huiyang Yin will suffice.
Fifth type: Dampness invading the Spleen can also cause sweating. Symptoms include heavy and fatigued body, slow and large pulse, and a voice sounding as if coming from an urn, which mostly indicates Dampness syndrome. If Heat-Dampness is predominant, removing the Fire will naturally clear the Dampness, using the methods for Yang syndromes mentioned above. If Cold-Dampness is predominant, assisting the Fire (Yang) will naturally recede the Dampness, using the methods for Yin syndromes mentioned above. Alternatively, Yupingfeng San, Sijunzi Tang (Four Gentlemen Decoction), or Wujunzi Jian (Five Gentlemen Decoction) can be used to strengthen Spleen Earth Qi; once Dampness is removed, sweating will cease.
Sixth type: Herbs for stopping sweating, such as Mahuang Gen (Ephedrae Radix), Fuxiaomai (Floating Wheat), Wumei (Mume Fructus), Bei Wuwei Zi (Schisandrae Chinensis Fructus), Xiaoheidou (Black Soybean), Longgu (Os Draconis), and Muli (Concha Ostreae), can be selected as appropriate. It is said that Huangqi (Astragali Radix) increases its efficacy when combined with Fangfeng (Saposhnikoviae Radix). It is also said that Guigui (Cinnamomi Cortex) is best at consolidating the exterior. Additionally, for excessive sweating that cannot be controlled, quickly grind Wubeizi (Galla Chinensis) into powder, mix with saliva, fill into the umbilicus, and bind tightly with a cloth; it will stop overnight. Alternatively, use Hemashouwu (Polygoni Multiflori Radix Praeparata) powder filled into the umbilicus and bound, which also stops sweating.
Seventh type: Night sweats in children are common. Physicians like Dongyuan (Li Gao) stated they need not be treated because the child's Blood and Qi are not yet sufficient. However, excessive sweating ultimately indicates Qi aspect deficiency. When I see children with severe sweating, I administer approximately one qian of Renshen (Ginseng Radix) decocted in water, which stops the sweating that very night. I fear that future physical strength may depend on this, so tonification is indispensable.
Eighth type: Post-illness excessive sweating, whether from Shanghan (Cold Damage) or Nueji (Malaria). For external Cold pathogens, if heat subsides after sweating but sweating does not stop immediately, this is because the exterior pathogen has just resolved, and the Couli and Wei Qi are still open and leaking. This sweating is normal; even if it lasts several days or ten days, it is harmless. Once Wei Qi gradually solidifies, sweating will stop naturally, requiring no worry. For other miscellaneous diseases, where sweating is not due to the resolution of an external pathogen, spontaneous or night sweats are inappropriate and must be treated.
