秦子曰∶余观严用和眩晕论云，眩掉诸症，《内经》皆主肝风上攻致是，而《原病式》
释之
内伤七情之症，皆能致眩晕者，于是立外感风寒暑湿四条，又立内伤痰涎下虚两条，实为眩
晕指南。然余惜其六气未全，七情未备，且其用方主治，又难于下手，刘宗浓议其论症亲切
，集方欠明，深中其弊。今余改立外感三条，内该六气，内伤四条，内该七情，而其主治之
方，皆按经对症，不得以平淡无奇而忽之也。
【风寒眩晕之症】头痛额痛，骨节烦痛，身热多汗，上气喘逆，躁扰时眩，此风邪眩晕
之症也。若身热无汗，恶寒拘紧，头痛、身痛，时时冒眩，此寒邪眩晕之症也。
【风寒眩晕之因】或风木司政，风热大作；或体虚不谨，外受风邪。风主乎阳，风热为
患，则
入胃，激动痰涎，亦令人眩晕。
【风寒眩晕之脉】左脉浮数，太阳风热；左脉浮弦，少阳风热；右脉浮数，阳明风热；
右
【风寒眩晕之治】左脉浮数，太阳风邪者，羌活防风汤，加天麻、黄芩。左脉浮弦，少
阳风热
滑大，症兼痰涎者，导痰汤加天麻、防风。左脉浮紧，太阳寒邪者，羌独败毒汤，加天麻、
细辛。左脉弦紧，少阳寒邪者，柴胡羌活汤，加天麻、川芎。右脉浮紧，阳明寒邪者，干葛
羌活汤，加天麻、升麻。大凡眩晕之症，多有兼痰者，故天麻方书多用之，今申明首条，则
以下诸条，皆可参而用也。

秦子说：我观察严用和的《眩晕论》，其中提到眩掉（头晕目眩、肢体动摇）等症状，《内经》都主张是肝风上攻导致的，而《原病式》解释内伤七情（喜、怒、忧、思、悲、恐、惊）引起的病症，都能导致眩晕。于是严用和确立了外感风寒暑湿四条，又确立了内伤痰涎和下虚两条，这实在是眩晕病的指南。然而，我可惜他六气（风、寒、暑、湿、燥、火）不全，七情不备，而且他所用方剂的主治，又难以入手操作。刘宗浓议论他的论述症状亲切，但收集方剂不够明确，这深深切中了其弊端。现在我重新确立外感三条，内部涵盖六气；内伤四条，内部涵盖七情。而其主治的方剂，都按照经络对症状，不能因为平淡无奇而忽视它。
【风寒眩晕的症状】头痛、额痛，骨节烦痛，身体发热、多汗，上气喘逆，烦躁扰动、时常眩晕，这是风邪眩晕的症状。如果身体发热、无汗，怕冷且身体拘紧，头痛、身痛，时时感到头昏眼花，这是寒邪眩晕的症状。
【风寒眩晕的原因】或者是风木司政（风气主令），风热大作；或者是体质虚弱且不谨慎，外受风邪。风属于阳，风热为患，则进入胃中，激动痰涎，也令人眩晕。
【风寒眩晕的脉象】左脉浮数，属太阳风热；左脉浮弦，属少阳风热；右脉浮数，属阳明风热；右脉……（原文此处中断）
【风寒眩晕的治疗】左脉浮数，属太阳风邪者，用羌活防风汤，加天麻、黄芩。左脉浮弦，属少阳风热……滑大，症状兼有痰涎者，用导痰汤加天麻、防风。左脉浮紧，属太阳寒邪者，用羌独败毒汤，加天麻、细辛。左脉弦紧，属少阳寒邪者，用柴胡羌活汤，加天麻、川芎。右脉浮紧，属阳明寒邪者，用干葛羌活汤，加天麻、升麻。大凡眩晕的症状，多有兼夹痰浊的，所以天麻在方书中多用。现在申明第一条，那么以下各条，都可以参考使用。

Qin Zi said: I have observed Yan Yonghe's "Treatise on Vertigo and Tremor," which states that symptoms such as vertigo (dizziness) and tremor (shaking of limbs), as described in the *Neijing* (Classic of Internal Medicine), are all attributed to Liver Wind attacking upwards. Meanwhile, the *Yuanbing Shi* (Manual of Original Causes of Disease) explains that internal injuries caused by the Seven Emotions (Joy, Anger, Worry, Thought, Sorrow, Fear, Fright) can all lead to vertigo. Thus, he established four categories for external contraction of Wind, Cold, Summerheat, and Dampness, and two categories for internal injury due to Phlegm-Fluids and Lower Deficiency, which truly serves as a guide for vertigo. However, I regret that his coverage of the Six Qi (Wind, Cold, Summerheat, Dampness, Dryness, Fire) is incomplete, and his treatment of the Seven Emotions is insufficient. Furthermore, the indications for his prescribed formulas are difficult to apply. Liu Zongnong commented that while his description of symptoms was pertinent, his collection of formulas lacked clarity, which accurately hit upon their shortcomings. Now, I re-establish three categories for external contraction, encompassing the Six Qi internally; and four categories for internal injury, encompassing the Seven Emotions internally. The formulas for treating these conditions are matched precisely to the meridians and symptoms, and should not be neglected merely because they appear plain or unremarkable.
[Symptoms of Vertigo due to Wind-Cold] Headache, frontal headache, painful and heavy joints, fever with profuse sweating, wheezing and counterflow qi, irritability with occasional vertigo—these are symptoms of vertigo caused by Wind Pathogen. If there is fever without sweating, aversion to cold with bodily stiffness, headache, body pain, and frequent sensations of dizziness and clouded vision—these are symptoms of vertigo caused by Cold Pathogen.
[Causes of Vertigo due to Wind-Cold] Either when Wind Wood governs the climate and Wind-Heat erupts violently; or when the constitution is deficient and one is careless, leading to external contraction of Wind Pathogen. Wind belongs to Yang. When Wind-Heat becomes a pathogenic factor, it enters the Stomach, agitates Phlegm-Fluids, and also causes vertigo in people.
[Pulse Signs of Vertigo due to Wind-Cold] A floating and rapid pulse on the left indicates Taiyang Wind-Heat; a floating and wiry pulse on the left indicates Shaoyang Wind-Heat; a floating and rapid pulse on the right indicates Yangming Wind-Heat; [the text breaks off here regarding the right pulse].
[Treatment of Vertigo due to Wind-Cold] For a floating and rapid pulse on the left, indicating Taiyang Wind Pathogen, use Qianghuo Fangfeng Tang (Notopterygium and Saposhnikovia Decoction), adding Tianma (Gastrodia Rhizome) and Huangqin (Scutellaria Root). For a floating and wiry pulse on the left, indicating Shaoyang Wind-Heat... [text gap]; if the pulse is slippery and large, and symptoms include Phlegm-Fluids, use Daotan Tang (Great Phlegm-Fluid Resolving Decoction) adding Tianma (Gastrodia Rhizome) and Fangfeng (Saposhnikovia Root). For a floating and tight pulse on the left, indicating Taiyang Cold Pathogen, use Qiangdu Baidu Tang (Notopterygium and Angelica Pubescens Detoxification Decoction), adding Tianma (Gastrodia Rhizome) and Xixin (Asarum Root). For a wiry and tight pulse on the left, indicating Shaoyang Cold Pathogen, use Chaihu Qianghuo Tang (Bupleurum and Notopterygium Decoction), adding Tianma (Gastrodia Rhizome) and Chuanxiong (Ligusticum Chuanxiong Rhizome). For a floating and tight pulse on the right, indicating Yangming Cold Pathogen, use Gange Qianghuo Tang (Pueraria and Notopterygium Decoction), adding Tianma (Gastrodia Rhizome) and Shengma (Cimicifugae Rhizome). Generally, vertigo symptoms often involve concurrent Phlegm-Dampness; therefore, Tianma (Gastrodia Rhizome) is frequently used in formularies. Having clarified the first category above, the subsequent categories can be referenced and applied accordingly.
