翻唇鱼口误针时。不日黄泉实可悲。此症亦名为恶症。卢医遇着也难医。
凡属喉风之症。预先必作寒发热。甚则大便秘结。小便涩赤头痛烦渴。时医不识。妄以羌活药味投之。不知羌

《黄帝内经》记载：“痈疮生于六腑，疽疮出于五脏。”这些病症都是由于阴阳之气相互阻滞而形成的。气属于阳，血属于阴。血液运行在脉管之中，气运行在脉管之外。气血相互伴随、周流全身。若受到寒湿之邪搏结，则气血凝滞而运行迟缓，这属于“不及”（功能低下）；若受到火热之邪搏结，则气血沸腾而运行加速，这属于“太过”（功能亢进）。气机郁结导致邪气侵入血中，称为“阳滞于阴”；血行郁滞导致邪气侵入气中，称为“阴滞于阳”。从而导致产生各种恶毒症状。然而，百病的发生皆由此机理所致。
凡是头痛不止的，属于外感病证，适宜用发散法治疗；时痛时止的，属于内伤病证，应当补益虚损。又有偏侧头痛者，（需仔细辨别是否属于偏头风证）。左侧头痛多属风邪与血虚，右侧头痛多属痰热与气虚。
面色发青的，病位属肝，宜用散血法；面色发黄的，病位属脾且运化停滞，宜用消食法；面色发红的，病位属心，宜用散血清火法；面色发白的，病位属肺，宜用顺气法；面色发黑的，病位属肾虚，应当滋补。以上所论述的五色变化，是针对各类风症痊愈后的调理而言，用以识别如何调理本经脏腑。
喉部内生风邪不可拖延，胸中气急预示病情危重。若再加上心胁部位如刀刺般疼痛，患者恐怕将与亲人永别。大小便出现秘结不通，病患魂魄似将飞离躯体。这是医家的真妙诀，预先告知你生死之兆。
当病患双眼直视、口张不开时，气息外泄无法收敛，手部松软下垂。若见到这种形态，医生应迅速停止治疗，不要贪恋名利而心存疑虑。
若出现翻唇、鱼口样改变，误施针刺，不久后患者将死亡，实在可悲。此症也称为恶症，即使是名医卢医（扁鹊）遇到也难以医治。
凡是属于喉风类的病症，发作前必定伴有怕冷发热，严重时会出现大便秘结、小便涩痛色赤、头痛、烦躁口渴等症状。当时的医生不认识此病，胡乱投用羌活等药物。不知道羌活是散发寒邪、通达肌表发表的药物，并不适合喉科使用。因此本书制定的紫正地黄散，专门治疗一切诸风病症，无不神效，确实是奇妙的秘方。
The *Huangdi Neijing* (Yellow Emperor's Inner Canon) states: "Carbuncles (Yong, 痈) arise from the six fu organs, and deep abscesses (Ju, 疽) emerge from the five zang organs." These conditions are all formed by the mutual stagnation of Yin and Yang. Qi belongs to Yang, and Blood belongs to Yin. Blood circulates within the vessels, while Qi circulates outside the vessels. They accompany each other and flow throughout the body. If constrained by Cold-Dampness, they coagulate and move slowly, which is termed "insufficiency" (Bu Ji, 不及). If constrained by Fire-Heat, they boil and move rapidly, which is termed "excess" (Tai Guo, 太过). When Qi stagnates and pathogens enter the Blood, it is called "Yang stagnating in Yin"; when Blood stagnates and pathogens enter the Qi, it is called "Yin stagnating in Yang." This leads to the generation of various malignant toxins. However, all diseases originate from this mechanism.
For those with continuous headache, it belongs to external contraction, and dispersing methods should be used. For those with intermittent headache, it belongs to internal injury, and deficiency should be tonified. Regarding unilateral headache, (one must carefully distinguish whether it is Bian Tou Feng, 偏头风). Left-sided headache often relates to Wind and Blood deficiency; right-sided headache often relates to Phlegm-Heat and Qi deficiency.
A bluish complexion indicates the disease involves the Liver; blood-dispersing methods are suitable. A yellowish complexion indicates Spleen stagnation; digestive-dissolving methods are suitable. A reddish complexion indicates the disease involves the Heart; blood-dispersing and fire-clearing methods are suitable. A whitish complexion indicates the disease involves the Lung; Qi-smoothing methods are suitable. A blackish complexion indicates Kidney deficiency; nourishing and tonifying methods are appropriate. The discussion of the Five Colors above refers to the post-recovery regulation of various Wind syndromes, serving to identify how to regulate the respective meridians.
When Wind generates internally in the throat, do not delay. Chest Qi urgency signals impending danger. If accompanied by stabbing pain in the heart and hypochondrium, separation from wife, children, relatives, and friends is certain. Constipation and difficult urination appear. The patient's soul seems to fly away. This is the true secret of physicians, informing you of life and death in advance.
When the patient's eyes are fixed open and mouth agape, Qi escapes without return, and hands hang limp. Upon seeing this form, one should quickly retire from treatment, abandoning greed for fame and wealth, and dispelling doubt.
If lips evert or the mouth resembles a fish's mouth, and acupuncture is mistakenly applied, death on the Yellow Springs (Huang Quan, 黄泉) will occur soon, which is truly sorrowful. This syndrome is also named an Evil Syndrome (E Zheng, 恶症); even Lu Yi (Lu Bi, 卢医 - referring to Bian Que) would find it difficult to treat.
For all syndromes belonging to Hou Feng (Throat Wind, 喉风), there must initially be aversion to cold and fever. In severe cases, there is constipation, scanty dark urine, headache, restlessness, and thirst. Contemporary physicians fail to recognize this and recklessly administer herbs like Qiang Huo (Notopterygii Rhizoma et Radix, 羌活). They do not know that Qiang Huo is a herb that disperses Cold pathogens and releases the exterior through the muscle layer, which is not suitable for throat treatments. Therefore, the Zi Zheng Di Huang San (Purple Correct Rehmannia Powder, 紫正地黄散) prescribed in this book specifically treats all kinds of Wind syndromes with miraculous efficacy. It is indeed a wonderful secret formula.
