呕吐而利名霍乱。（仲景云。病有霍乱者。何也。答曰呕吐而利。此名霍乱。）四肢逆冷诚斯患。寒多不饮理中丸。
热多而渴五苓散。（仲景云。霍乱而头痛发热。身体疼痛。热多。欲饮水。五苓散。寒多不饮水者。理中丸主之。又云。

手足若厥者。其人头必痛。若不呕不饮。手足不厥者。其头不痛。）少阳受病脉弦细。小柴胡证自分明。（仲景云。伤寒。
其脉弦细。头痛发热。此为属少阳。少阳不可发汗。则谵语为属胃。胃和则愈。不和则烦而悸。）三阴太少无头痛。为是

Vomiting accompanied by diarrhea is named Huoluan (Huo Luan, Cholera-like syndrome). (Zhang Zhongjing said: Regarding the disease of Huoluan, what is it? The answer is: vomiting and diarrhea, this is named Huoluan.) Cold reversal in the four limbs is indeed a calamity of this condition. For cases with excess cold and no desire to drink, Lizhong Wan (Regulate the Middle Pill) is indicated.
For cases with excess heat and thirst, Wuling San (Five-Ingredient Powder with Poria) is indicated. (Zhang Zhongjing said: In Huoluan with headache, fever, body pain, and excess heat, with a desire to drink water, Wuling San is used; for those with excess cold and no desire to drink, Lizhong Wan is the primary treatment. He also stated: In cases of vomiting and diarrhea with sweating, fever, aversion to cold, tetanic contraction of the four limbs, and cold hands and feet, Sini Tang (Frigid Extremities Decoction) is used.) In the summer months, sudden pinching pain in the heart region, spasms in both legs with profuse cold sweat, upper vomiting and lower diarrhea accompanied by restlessness, should be treated by decocting Chensiang (Aquilaria Wood) and Yishu (Mosla Herb) and drinking several cups. (In summer, yin and yang are disharmonious, clear and turbid qi interfere with each other. Overeating damages the spleen and stomach, and seeking coolness exposes one to cold. Yin and yang become intermixed, resulting in vomiting and diarrhea, chaos in the Triple Burner, pinching abdominal pain, extreme thirst and vexation, and leg spasms. Xiangru San (Elsholtzia Powder) should be used.)
The Three Yang meridians often suffer from headaches; treating according to symptoms (Ping Sheng, level tone) varies and must be distinct to be effective. (The Three Yang meridians ascend to the head, while the Three Yin meridians ascend only to the chest and return. Therefore, pathogenic factors in the Three Yang meridians reaching the head inevitably cause headaches.) Taiyang (Greater Yang) presentation with body heat is the indication for Mahuang Tang (Ephedra Decoction). (Zhang Zhongjing said: In Taiyang disease with headache, fever, body pain, absence of sweating, and wheezing, Mahuang Tang is indicated.) Yangming (Yang Brightness) presentation without fever indicates steaming of Stomach Qi. (Zhang Zhongjing said: In Yangming disease, if the hands and feet are cold, the head must hurt; if there is no vomiting, no thirst, and the hands and feet are not cold, the head does not hurt.) Shaoyang (Lesser Yang) disease presents with wiry and fine pulses, and the Xiao Chaihu Tang (Minor Bupleurum Decoction) pattern is clearly defined. (Zhang Zhongjing said: In Shanghan (Cold Damage), a wiry and fine pulse with headache and fever indicates involvement of Shaoyang. Shaoyang should not be induced to sweat; if mistakenly sweated, delirium indicates involvement of the Stomach. If the Stomach harmonizes, recovery occurs; if not, vexation and palpitations ensue.) The Three Yin meridians, specifically Taiyin and Shaoyin, do not typically present with headaches; only Jueyin (Terminal Yin) has this manifestation. (Among the Three Yin meridians, Taiyin and Shaoyin do not have headaches; only Jueyin does.) Sudden onset of headache at an inappropriate time. ("Xiao" sound, from Rites of Zhou.) It must be due to retained phlegm and dampness. (Retained phlegm and dampness can also cause headaches.)
