秦子曰∶泄泻之症，或泻白，或泻黄，或泻清水，或泻水谷，不杂脓血，名曰泄泻。
若带稠粘之积，则是痢疾，而非泄泻之症矣。今列外感五条，内伤五条，又五更泄泻五条。
【风泻之症】自汗头汗，恶风发热，头痛额疼，泻下水谷，或下清水，此伤风飧泄之症
【风泻之因】风邪入于肠胃之间，则有泄泻之患。经云∶春伤于风，夏必飧泄。此
【风泻之脉】多浮而弦，左关浮弦，风木之邪。大肠脉浮，乃是肠风。右关脉浮，胃风
【风泻之治】左关浮弦，柴胡防风汤，调五苓散。大肠脉弦，风入阳明，干葛防风汤，
下六一散。右关脉弦，风邪入胃，防葛汤，调胃苓散。总之，有表当散表，表既散，当分利

【寒泻之症】恶寒身痛，不发热，口不渴，小便清白，腹中疼痛，泄泻水谷，此寒邪直
中三阴经之寒泻症也。若恶寒身痛，身反发热，口反渴，此寒伤三阳经之热泻症也。

Qin Zi said: The symptoms of Xie Xie (diarrhea) include discharging white stool, yellow stool, clear water, or undigested food mixed with water, without pus and blood. This is called Xie Xie (diarrhea).
If the stool contains sticky accumulation, it is Li Ji (dysentery), not a symptom of Xie Xie (diarrhea). Now, five categories of exogenous causes, five categories of endogenous injuries, and five categories of Wugeng Xie Xie (predawn diarrhea) are listed.
[Symptoms of Wind-induced Diarrhea] Spontaneous sweating, sweating on the head, aversion to wind, fever, headache, and frontal pain, with discharge of undigested food and water, or clear water. This is the symptom of Sun Fen (diarrhea with undigested food) caused by wind injury.
[Etiology of Wind-induced Diarrhea] When wind pathogen enters between the stomach and intestines, diarrhea occurs. The Classics state: "Injury by wind in spring leads to Sun Fen (diarrhea with undigested food) in summer." This...
[Pulse of Wind-induced Diarrhea] The pulse is mostly floating and wiry. Left Guan (Cun-Guan-Chi at the radial artery) floating and wiry indicates wind-liver wood pathogen. Large intestine pulse floating indicates Chang Feng (intestinal wind). Right Guan pulse floating indicates Wei Feng (stomach wind)...
[Treatment of Wind-induced Diarrhea] If the Left Guan pulse is floating and wiry, use Chai Hu Fang Feng Tang (Bupleurum and Saposhnikovia Decoction), combined with Wu Ling San (Five-Ingredient Powder with Poria). If the large intestine pulse is wiry, wind has entered the Yangming channel; use Gan Ge Fang Feng Tang (Kudzu Root and Saposhnikovia Decoction), combined with Liu Yi San (Six-to-One Powder). If the Right Guan pulse is wiry, wind pathogen has entered the stomach; use Fang Ge Tang (Saposhnikovia and Kudzu Root Decoction), combined with Wei Ling San (Stomach-Poria Powder). In general, if there is an exterior syndrome, resolve the exterior first. Once the exterior is resolved, separate and drain dampness.

[Symptoms of Cold-induced Diarrhea] Aversion to cold, body ache, no fever, no thirst, clear and copious urine, abdominal pain, and discharge of undigested food and water. This is the Cold Diarrhea syndrome where cold pathogen directly invades the Three Yin channels. If there is aversion to cold, body ache, but the body is conversely feverish, and the mouth is conversely thirsty, this is the Heat Diarrhea syndrome where cold pathogen injures the Three Yang channels.
[Etiology of Cold-induced Diarrhea] If True Yang (Zhen Yang) is inherently deficient, and one encounters seasonal cold, which directly invades the Three Yin channels, then the body will not be feverish, nor will there be thirst, urine will be profuse, and abdominal pain will occur, leading to the manifestation of Zhong Han Xia Li (cold invasion causing lower purging). If there is heat in the stomach and intestines, external cold binds the skin and hair, preventing internal heat from venting, then cold transforms into...
[Pulse of Cold-induced Diarrhea] Right Guan pulse deep and slow indicates cold invading Taiyin channel. Left Chi pulse deep and slow indicates cold invading Shaoyin channel; Left Guan pulse deep and slow indicates cold invading Jueyin channel. If the body is feverish and the pulse is floating and tight, cold has injured Taiyang channel. If the body is feverish and the pulse is floating and wiry, cold has injured Shaoyang channel. If the body is feverish and the pulse is long, with only the Right Cun and Guan pulses being particularly large, cold has injured Yangming channel.
[Treatment of Cold-induced Diarrhea] For Three Yin cold diarrhea, Li Zhong Tang (Regulate the Middle Decoction), Si Ni Tang (Reverse the Collapse Decoction), and Zhen Wu Tang (True Warrior Decoction) are primarily used. For heat diarrhea caused by cold injuring the Three Yang channels, one should resolve the exterior: Taiyang channel uses Qiang Huo Tang (Notopterygium Decoction); Yangming channel uses Ge Gen Tang (Kudzu Root Decoction); Shaoyang channel uses Xiao Chai Hu Tang (Minor Bupleurum Decoction). For those requiring clearing of heat, Ge Gen Huang Qin Huang Lian Tang (Kudzu Root, Scutellaria, and Coptis Decoction) and Huang Qin Tang (Scutellaria Decoction) are primarily used.
