一忽又一忽，终日睡着沉沉不醒，惟狐惑二证有之，乃因下利后，内热乘虚
生虫，杀人甚急，宜桃仁汤，黄连犀角汤。
终日终夜常眠不寤，惟少阴下后，心肾虚寒，宜四逆温之。
有欲幽静而但不能眠熟，惟百合、风温二症有之。百合因汗下后，内外俱
虚，气无以守，心神不宁，汗后成者，百合知母汤；下后成者，滑石代赭汤。吐
后成者，鸡子汤。不曾汗吐下，自成者，百合地黄汤。
热也，津液结搏为膜在舌上。
白滑者，邪气初传入里，客于胸中，栀子豉汤主之。
又阳明误下，白胎者，同治。
半表半里者，小柴胡汤主之。
不滑而涩，是结热在里，表里俱热，口大干，舌上干燥，白虎汤加参主之。
黄者热邪入里，可下之。
黑者热极也死。
衄，头汗出，身无汗，死。及汗出不至足者死。
发衄家汗，则额上陷，脉紧急，直视不得 ，不得眠。
少阴病，但厥无汗，强汗之，因致衄者，难治，名曰下厥上竭。
KT 者，但胸喉间气塞不得下通然，而无声也。
哕者，吃吃然有声也。二者皆胃受疾也，趺阳浮为KT ，滑为哕。KT 者，胃虚
水寒相搏，宜小青龙去麻黄加附子；哕者，因大吐大下，胃虚之极也，此妄下之过，多不治。
又有热气拥，郁气不得通而成轻者，有和解之证，重者有攻下之候，非比大下后。
Every so often, the patient hiccups or belches, sleeping heavily and unroused throughout the day. This occurs only in *Huo Huo* (Foxes Disease, characterized by ulcers of the mouth, throat, and genitals) and *Gan Huo Luan* (Dry Cholera, an acute condition with abdominal pain, inability to vomit or defecate). It arises from intestinal worms generated by internal heat taking advantage of deficiency after diarrhea; it is fatal if not treated promptly. The appropriate formulas are *Taoren Tang* (Peach Kernel Decoction) or *Huanglian Xijiao Tang* (Coptis and Rhinoceros Horn Decoction).
Sleeping constantly throughout the day and night without waking occurs only in *Shaoyin* disease after improper purgation, where heart and kidney yang are deficient and cold. The appropriate treatment is to warm with *Sini Tang* (Frigid Extremities Decoction).
Desiring quietness but unable to sleep soundly occurs only in *Baihe Bing* (Lily Disease, a psychosomatic disorder characterized by mental restlessness and sensory disturbances) and *Fengwen* (Wind-Warmth, an exogenous febrile disease caused by wind-heat pathogens). *Baihe Bing* results from excessive sweating or purgation leading to deficiency in both interior and exterior, causing qi to fail in anchoring and the mind-spirit to become unsettled. If formed after sweating, treat with *Baihe Zhimu Tang* (Lily and Anemarrhena Decoction); if formed after purgation, treat with *Huashi Daizhe Tang* (Talcum and Hematite Decoction); if formed after vomiting, treat with *Jizi Huang Tang* (Egg Yolk Decoction); if formed naturally without prior sweating, vomiting, or purgation, treat with *Baihe Dihuang Tang* (Lily and Rehmannia Decoction).
A white coating that is dry indicates heat condensing body fluids into a membrane on the tongue.
A white and slippery coating indicates pathogenic factors just entering the interior and lodging in the chest; treat primarily with *Zhizi Chi Tang* (Gardenia and Fermented Soybean Decoction).
Additionally, if a white coating appears after improper purgation in *Yangming* disease, the same treatment applies.
For conditions located at the half-exterior and half-interior, treat primarily with *Xiao Chaihu Tang* (Minor Bupleurum Decoction).
If the coating is not slippery but rough/astringent, it indicates heat binding in the interior with fever in both exterior and interior, severe thirst, and a dry tongue; treat primarily with *Baihu Tang* (White Tiger Decoction) added with Ginseng (*Renshen*).
A yellow coating indicates heat pathogens entering the interior; purgation may be used.
A black coating indicates extreme heat and is often fatal.
In *Zang Jie* (Organ Binding), a white and slippery coating indicates death. The presentation resembles *Jie Xiong* (Binding Chest syndrome), with normal appetite but frequent diarrhea.
Heat in the exterior indicates excessive heat in the meridians and collaterals, with yang qi congestion forcing blood to move recklessly. Epistaxis (nosebleed) allows for self-resolution; sweating methods are contraindicated.
Epistaxis accompanied by sweating only on the head and no sweating on the body indicates death. Similarly, sweating that does not reach the feet indicates death.
Inducing sweating in patients prone to epistaxis leads to sunken temples, urgent pulse, fixed gaze, and insomnia.
In *Shaoyin* disease, if there are only cold extremities without sweat, and forced sweating induces epistaxis, the condition is difficult to treat and is named *Xia Jue Shang Jie* (Lower Cold and Upper Exhaustion).
*Yi Qi* (belching) is characterized by a sensation of qi blockage in the chest and throat without sound. *Yue* (hiccup/hiccough) is characterized by audible "chi chi" sounds. Both are diseases of the stomach. A floating pulse at the *Duyang* position indicates *Yi Qi*; a slippery pulse indicates *Yue*. *Yi Qi* is caused by stomach deficiency with water-cold binding; treat with *Xiao Qinglong Tang* (Minor Green Dragon Decoction) minus *Mahuang* (Ephedrae Herba) plus *Fuzi* (Aconiti Lateralis Radix Praeparata). *Yue* results from extreme stomach deficiency due to severe vomiting and purgation, often caused by erroneous purgation, and is mostly incurable.
There are also mild cases caused by heat qi congestion and stagnant qi failing to circulate, presenting as harmonization syndromes; severe cases present with signs requiring purgation. These differ from conditions following major purgation.
