目者肝、脾、肺、肾所属。红丝缠绕，此脾火传肺，肺传肾，肾传肝。治宜重清脾热，兼治三经，而
红目退。误以眼科治之，为害不浅。
头为一身之元首，最轻清而邪不易干。通身焦燥独头汗涌出，此烈毒鼎沸于内，热气上腾，故汗出如
涌。
齿者骨之余。有以切牙为血虚，谓杂证则然耳。疫疹切牙，是肝经热极。肝为血海，被火煎熬，牙失
其养，故频频而作。
杂症鼻衄，迫于肺经浮游之火，而疫乃阳明郁热上冲于脑。鼻通于脑，热血上溢，故从鼻出如泉。
舌上白点如珠，乃水化之象，较之紫赤黄黑，古人谓之芒刺者更重。
（此三十六舌未有者）
疫症初起，苔如腻粉，此火极水化。医者误认为寒，妄投温表，其病反剧，其苔愈浓，加以重剂，以
致精液愈耗，水不上升，二火煎熬，变白为黑，其坚
如铁，其浓如甲，敲之戛戛有声，言语不清，非舌卷也。治之得法，其甲整脱。（经验）
（亦三十六舌未有）
发于舌上，或红或紫，大如马乳，小如樱桃，三五不等，流脓出血。重清心火，舌上成坑，愈后自
平。（经验）
热病愈后，舌出寸余，累日不收，名曰阳强。因犯房劳而得。长数寸者不救。
牙床属胃，齿统十二经。此阳明热传少阴，二经相并，故血出牙缝。
The eyes are associated with the Liver, Spleen, Lung, and Kidney. The entanglement of red filaments indicates that Fire from the Spleen transmits to the Lung, then to the Kidney, and finally to the Liver. Treatment should focus on heavily clearing Spleen Heat while simultaneously addressing these three meridians, after which the redness of the eyes will recede. Treating this mistakenly as an ophthalmological disorder causes significant harm.
The head is the chief of the body, possessing the lightest and clearest Qi, making it difficult for pathogenic factors to invade. Generalized dryness and agitation accompanied by profuse sweating only on the head indicate that intense toxicity is boiling within, causing rising Heat, thus resulting in sweat gushing forth.
Teeth are the surplus of bone. Some attribute teeth grinding to Blood deficiency, which may be true for miscellaneous diseases. However, teeth grinding in epidemic macules is due to extreme Heat in the Liver meridian. The Liver is the Sea of Blood; when subjected to Fire simmering, the teeth lose their nourishment, leading to frequent episodes.
In miscellaneous diseases, epistaxis (nosebleed) is forced by floating Fire in the Lung meridian. In epidemics, however, it is Stagnant Heat in the Yangming channel rushing upward to the brain. Since the nose connects to the brain, hot Blood overflows, causing blood to flow from the nose like a spring.
White spots on the tongue resembling pearls represent the transformation into Water. This condition is more severe than the purple, crimson, yellow, or black colors, and even more so than the "thorns" described by ancient physicians.
(This is a tongue manifestation not recorded in the traditional Thirty-Six Tongue Diagnoses.)
At the onset of epidemic disease, the coating resembles greasy powder, indicating that extreme Fire transforms into Water. If physicians mistakenly diagnose this as Cold and recklessly administer warming and releasing formulas, the condition worsens, and the coating becomes thicker. Administering heavy doses further depletes Essence and Fluids, preventing Water from ascending. Simmered by dual Fires, the coating turns white to black, becoming hard as iron and thick as armor, producing a clattering sound when struck. Speech becomes unclear, but this is not tongue rolling. With correct treatment, the armor-like coating will detach completely. (Empirical experience)
(Also not found in the traditional Thirty-Six Tongue Diagnoses.)
Manifesting on the tongue, varying in color from red to purple, ranging in size from horse milk to cherry, in numbers of three to five or more, discharging pus and bleeding. One must heavily clear Heart Fire. Pits will form on the tongue surface, which will level out naturally upon recovery. (Empirical experience)
After the resolution of febrile disease, if the tongue protrudes more than one cun and cannot retract for days, it is named Yang Excess (Yang Qiang). This results from sexual indiscretion. If the tongue extends several inches, it is incurable.
When Liver Heat is excessively strong, Blood has nowhere to store itself and overflows upward through the Heart's opening (the tongue) and exits.
The gums belong to the Stomach, while the teeth are governed by the twelve meridians. This occurs when Heat from the Yangming channel transmits to the Shaoyin channel; the two channels combine, causing blood to bleed from between the teeth.
