夫阳喉者，阳气发显于外也。其色红，其气滚热，其舌强硬，其胸紧气急，大便坚硬，
小便
涩数，其面必红，其内外红肿之处必大热，其口气必滚热而臭，其眼内必红，其喉镜内必起
红丝线经络，其口唇必红而粗浓，其阳分发热潮热必甚，其痰涎壅甚，其言语雄壮，其声怒
，则其症实乃阳喉也。可用清心平肝泻脾寒凉之药治之。
夫阴喉者，阴气伏藏于内也。其色青白黄，其气温凉，其舌软必卷缩，其胸宽，其大小
便自
通利，其面色青黄，其内外肿处青，亦复温凉本色，其眼黄，其喉镜内色淡，其舌色白黄，
其阴分潮热，或微寒微热，其痰涎少，其声温和，其症则虚，是乃阴喉也。不可太用寒凉之
药，宜重用元参泻虚火为主。
五脏者，心肝脾肺肾也，各载五形，各形五色。五形者，金、木、水、火、土也。五色
者，
红、青、黄、白、黑、也。相生者其病轻，相克者其病重。假如其色红，则属心；其色青，
则属肝；其色黄，则属脾；其色白，则属肺；其色黑，则属肾；此乃五脏中形见于五色也。
开其口一观喉中形色，即知其由何脏中发来，相生者易治，相克者难医。此是传授真口诀，
切勿视为等闲语。
毒攻心必狂言乱语，毒攻肝其眼怒直视，毒攻肺其声嘶而咳嗽气响，毒攻肾其声沉缓而
哑，
毒攻脾颈上浮肿必结核，此乃余毒发来，外用冲和散敷之则散，不散则熟，用针刺出脓血即
愈。以上系毒攻脏腑之症。谚云∶毒攻脏腑为死症，古人不治，命由天。
阳喉，是阳气显露于体外的表现。其咽喉颜色红赤，气息滚烫灼热，舌头僵硬强硬，胸部紧缩且呼吸急促，大便干结坚硬，小便涩滞且频数，面色必定发红，内外红肿的部位必定非常烫手发热，口中气息必定滚烫且伴有臭味，眼睛内部必定发红，喉镜（观察咽喉的器具）内必定出现红色的丝状经络纹理，口唇必定红而肿胀粗厚，阳分出现的发热或潮热必定严重，痰涎壅盛阻塞，言语声音雄壮有力，发声如怒斥般响亮，那么这种病症确实就是阳喉。可以使用清心、平肝、泻脾的寒凉药物进行治疗。
阴喉，是阴气潜伏藏匿于体内的表现。其咽喉颜色呈青、白、黄三色，气息温度温凉，舌头柔软且必然卷缩，胸部宽舒，大小便自然通畅，面色青黄，内外肿胀之处呈现青色，也保持温凉的本来色泽，眼睛发黄，喉镜内颜色淡白，舌色白黄，阴分出现潮热，或者微有恶寒微有发热，痰涎稀少，声音温和，这种病症属于虚证，这就是阴喉。不可以过多使用寒凉药物，适宜重用玄参以清泻虚火为主治原则。
五脏，指的是心、肝、脾、肺、肾，各自承载五种形态，每种形态对应一种颜色。五形，指的是金、木、水、火、土五行。五色，指的是红、青、黄、白、黑五种颜色。相生关系的病变较轻，相克关系的病变较重。假如颜色发红，则归属于心；颜色发青，则归属于肝；颜色发黄，则归属于脾；颜色发白，则归属于肺；颜色发黑，则归属于肾；这是五脏中的形态显现于五色之中的道理。张开嘴巴观察咽喉中的形色，就能知道疾病是由哪一脏发起的，相生关系的容易治疗，相克关系的难以医治。这是传承下来的真正口诀，千万不要把它当作平常的话来看待。
毒邪攻心必定导致胡言乱语，毒邪攻肝导致眼睛怒视直视，毒邪攻肺导致声音嘶哑且咳嗽气喘有声，毒邪攻肾导致声音低沉缓慢且喑哑，毒邪攻脾导致颈部上方浮肿并必然形成结核肿块，这是余毒发作的表现，外用冲和散敷贴即可消散，如果不消散则会化脓，用针刺破排出脓血即可痊愈。以上这些是毒邪攻犯脏腑的症状。谚语说：毒邪攻犯脏腑属于死症，古人不予治疗，听凭命运安排。
Yang throat (Yang Hou) refers to the manifestation of Yang Qi on the exterior. The color is red, the breath is scalding hot, the tongue is stiff and rigid, the chest feels tight with rapid breathing, the stool is dry and hard, the urine is scanty, difficult to pass, and frequent, the facial complexion must be red, the swollen areas inside and outside must be extremely hot to the touch, the breath from the mouth must be scalding and foul, the interior of the eyes must be red, the laryngoscope (throat mirror) reveals red thread-like meridians, the lips are red and swollen/thick, the fever or tidal fever in the Yang aspect is severe, there is excessive phlegm and saliva obstruction, speech is vigorous and loud, and the voice sounds angry; thus, this condition is indeed Yang throat. It can be treated with cold-natured herbs that clear the Heart, calm the Liver, and drain the Spleen.
Yin throat (Yin Hou) refers to the concealment of Yin Qi within. The color is cyan, white, or yellow, the breath temperature is warm and cool, the tongue is soft and inevitably curled/shrunken, the chest is wide/relaxed, urination and defecation are naturally smooth, the facial complexion is cyan and yellow, the swollen areas inside and outside are cyan, retaining their natural warm-cool state, the eyes are yellow, the interior of the laryngoscope appears pale, the tongue coating is white and yellow, there is tidal fever in the Yin aspect, or slight chills and slight fever, phlegm and saliva are scanty, the voice is mild and gentle, and the condition is deficient; thus, this is Yin throat. One should not use cold-natured drugs excessively; instead, one should heavily use Xuanshen (Scrophulariae Radix) as the main treatment to clear deficiency fire.
The Five Zang Organs refer to the Heart, Liver, Spleen, Lung, and Kidney. Each carries five forms, and each form corresponds to a color. The Five Forms refer to Metal, Wood, Water, Fire, and Earth. The Five Colors refer to Red, Cyan, Yellow, White, and Black. Diseases arising from generating relationships are mild, while those arising from overcoming relationships are severe. If the color is red, it belongs to the Heart; if cyan, to the Liver; if yellow, to the Spleen; if white, to the Lung; if black, to the Kidney. This is how the forms of the Five Zang manifest in the five colors. By opening the mouth to observe the color and shape in the throat, one can know which Zang organ initiated the disease. Generating relationships are easy to treat; overcoming relationships are difficult to cure. This is the authentic secret formula passed down; do not regard it as trivial words.
When pathogenic toxin attacks the Heart, it causes delirious and confused speech. When attacking the Liver, it causes the eyes to glare and stare straight ahead. When attacking the Lung, it causes hoarseness, coughing, and noisy breathing. When attacking the Kidney, it causes a deep, slow, and aphonic voice. When attacking the Spleen, it causes swelling above the neck and the formation of tubercles/lumps. This is the manifestation of residual toxin. Applying Chonghe San externally will cause it to dissipate; if it does not dissipate, it will suppurate, and pricking it with a needle to drain pus and blood will lead to recovery. The above are the symptoms of toxin attacking the Zang-Fu organs. As the proverb says: Toxin attacking the Zang-Fu organs is a fatal condition; ancient physicians did not treat it, leaving life to Heaven's will.
