心虚盗汗睡多惊，酸枣仁汤服即宁，心火伤阴必烦热，当归六黄汤奏功。
[注]
盗汗有二，虚实两分，
心虚者阴气不敛也，睡则多惊，以酸枣仁汤主之，
心热者，火伤于阴也，身多烦热，以当归六黄汤主之。
(酸枣仁汤) 当归 白芍炒 生地 茯苓 酸枣仁炒 知母炒 黄蘖炒

阴乘阳热血妄行，血犯气分不归经，血病及腑渗浊道，伤于藏者溢出清，
热犯阳络上吐衄，热侵阴络下失红，又有努劳成血病，血止仍嗽势多凶。
[注]
凡失血之证，阳盛乘阴，则血为热迫，不能安于脉中，
犯于气分，妄行不能归入经脉也，
若血病伤及于腑者，则血渗入肠胃之浊道上行于咽，出而为吐为衄，
下从二便而出，为便为溺也，
若血病伤及于藏者，则溢出于胸中之清道，上从喉出而兼咳嗽，
下从精窍而出，为溺血也，
失血藏于脏内，行于脉中，流于躯壳之内，
不可得而见也，非损伤不能为病，
而损之因有三，
一曰热伤阳络，腑病也，热伤阴络，藏病也，宜以清热为主，
一曰努伤，宜以破逐为主，
一曰劳伤，宜以理损为主，
若日久血止，而咳嗽不休者，主必死之证，故势多凶也。

失血门
Sweat during sleep (Dao Han) caused by Heart Qi deficiency, accompanied by frequent startles in sleep, is calmed immediately by taking Suanzaoren Tang (Sour Jujube Decoction); if Heart Fire injures Yin and inevitably causes irritability and fever, Danggui Liu Huang Tang (Angelica Hexapartite Decoction) achieves efficacy.
[Note]
Sweat during sleep (Dao Han) is divided into deficiency and excess patterns.
Heart deficiency implies that Yin Qi fails to consolidate; with frequent startles during sleep, Suanzaoren Tang (Sour Jujube Decoction) is the primary formula.
Heart heat implies that Fire injures Yin; with bodily irritability and heat, Danggui Liu Huang Tang (Angelica Hexapartite Decoction) is the primary formula.
(Composition of Suanzaoren Tang [Sour Jujube Decoction]): Danggui (Angelicae Sinensis Radix), Chao Baishao (Fried White Peony Root), Shengdihuang (Rehmanniae Radix), Fuling (Poria), Chao Suanzaoren (Fried Semen Ziziphi Spinosae), Chao Zhimu (Fried Rhizoma Anemarrhenae), Chao Huangbo (Fried Cortex Phellodendri), Wuweizi (Schisandrae Fructus), Renshen (Ginseng Radix), Chao Huangqi (Fried Astragali Membranacei Radix). Decoct in water and take orally.
(Verse for Formula)
Suanzaoren Tang (Sour Jujube Decoction) treats sweat during sleep; Yang fails to store due to fundamental Yin deficiency. It contains Danggui, Baishao, Shengdihuang, Fuling, and Suanzaoren; Zhimu, Huangbo, Wuweizi, Renshen, and Huangqi are combined.
(Composition of Danggui Liu Huang Tang [Angelica Hexapartite Decoction])
Danggui (Angelicae Sinensis Radix), Shengdihuang (Rehmanniae Radix), Shudihuang (Prepared Rehmanniae Radix), Huangqin (Scutellariae Radix), Huangbo (Phellodendri Cortex), Huanglian (Coptidis Rhizoma), Zhi Huangqi (Honey-fried Astragali Membranacei Radix). Decoct with Fu Mai (Tritici Levigati Fructus) in water and take orally.
(Verse for Formula)
Danggui Liu Huang Tang (Angelica Hexapartite Decoction) treats sweat during sleep; Excess Yang injures Yin causing fluids to flow freely. Shengdihuang, Shudihuang, Huangqin, Huanglian, and Huangbo are used; Danggui, Huangqi, and Fu Mai can stop sweating.

Yin encroaching on Yang leads to reckless movement of hot blood; when Blood pathology invades the Qi level, it fails to return to the meridians. If Blood pathology affects the Fu organs, it seeps into the turbid pathways (excretory channels); if it injures the Zang organs, it overflows from the clear pathways (respiratory and reproductive channels).
Heat invading the Yang collaterals causes upper hematemesis or epistaxis; Heat invading the Yin collaterals causes lower hematochezia or hematuria. There is also blood disease resulting from strenuous labor; even if bleeding stops, persistent coughing indicates a generally ominous prognosis.
[Note]
In all cases of blood loss, Excess Yang encroaches on Yin, forcing blood with heat so that it cannot remain safely within the vessels.
It invades the Qi level, moving recklessly and failing to return to the meridians.
If blood pathology injures the Fu organs, blood seeps into the turbid pathways of the intestines and stomach, ascending to the pharynx, manifesting as vomiting or epistaxis.
Descending through the two excretions, it manifests as hematochezia or hematuria.
If blood pathology injures the Zang organs, it overflows from the clear pathways in the chest, ascending through the throat accompanied by coughing,
and descending through the essence orifice, manifesting as hematuria.
Blood is stored within the Zang, circulates within the vessels, and flows within the body shell;
it is invisible under normal conditions and only becomes pathological upon injury.
There are three causes of such injury:
First, Heat injuring the Yang collaterals constitutes a Fu organ disease; Heat injuring the Yin collaterals constitutes a Zang organ disease. The treatment should primarily focus on clearing heat.
Second, Injury from strain (Nu Shang) requires treatment primarily focused on breaking stasis and expelling blood.
Third, Injury from fatigue (Lao Shang) requires treatment primarily focused on regulating deficiency and damage.
If, after a long duration, bleeding has stopped but coughing persists without relief, it indicates a fatal condition, hence the prognosis is generally ominous.
