阳血妄动，则牙龈中的血色黄如败酱；胃热极盛，则牙齿干燥如石头且有光泽。肾阴血妄动，则牙龈中的血瓣紫如黑漆；肾液耗干，则牙齿枯槁如骨头且无神采。甚至牙齿突然脱落，或者出现穿腮牙疳，均为极其危险的病症。此时亟需使用下夺（泻下攻积）的方剂，以潜降龙雷之火，不使肾液被煎熬枯竭，从而避免阴气从下部衰竭。随后再用育阴的药剂，希望能在赤地（阴虚火旺之象）中流出膏脂（滋养阴液），不要令胃液消亡，致使阳气从上部厥逆。
时行疫气并非由风邪传播，所以列子说“风是大地的噎气”。这种气息虽然像阴霾不开之气，但一旦遇到风的鼓荡，就会随之变化而成为阳邪。因此，疫病属于阳邪，是阳热淫溢的热疾。初感在表，虽然表现为恶寒，但邪气的来源本于火热，这是双解法中凉散兼施的原因一。至于恶寒的缘故，是因为风伤卫分，热伤气分，导致卫气不敌而退缩，邪气即胜之而寒作。阳邪鼓动最快，既侵入卫分，随即随着卫气出入，又从卫分化而为热。病源在于卫分，对原本的阴营并无损伤，但如果久留卫分而不祛除，将会导致风胜则动、热胜则肿，于是阳亢阴消，阴也被灼耗而营分受伤。所以疏达（疏散透邪）与养阴不能偏废，这是双解法应当施用的原因二。另外，如果初起时神情呆滞，痧点隐约，燥热烂喉，来势猛烈，在此之际，如果辨证不清而以小剂量尝试，简直是优柔寡断、养奸为患，必定酿成巨大祸患。这就好比用一杯水去救一车柴的火，只会增加火势罢了。
When Yang blood moves recklessly, the color of the blood in the gums is yellow like spoiled sauce; when Stomach heat is extremely abundant, the teeth are dry like stone and have a luster. When Kidney Yin blood moves recklessly, the blood lobes in the gums are purple like black lacquer; when Kidney fluid is exhausted, the teeth are withered like bone and lack luster. Even if the teeth suddenly fall out, or if one suffers from "chuan sai ya gan" (cheek-penetrating gum disease), these are all extremely dangerous conditions. At this time, it is urgent to use purgative formulas (Xia Duo Fang) to subdue the fire of Dragon and Lei (Long Men Huo), so as not to let the Kidney fluid be boiled dry, thereby avoiding the exhaustion of Yin from below. Subsequently, use nourishing Yin agents to hope for the flow of essence (Gao) on barren land (Chi Di), preventing the consumption of Stomach fluids which would cause Yang to rebel upwards.
Seasonal epidemic qi does not spread via wind, hence Liezi stated that "wind is the stagnation of the earth." Although this qi resembles stagnant gloomy air, once stirred by wind, it transforms into Yang. Therefore, epidemics belong to Yang pathogens and are hot diseases caused by excessive Yang. Initially affecting the exterior, although chills are present, the origin of the pathogen lies in fire and heat; this is the first reason for applying the Double Resolution method (Shuang Jie Fa), which combines cooling and dispersing properties. As for the cause of chills, it is because wind injures the Wei (Defensive) level and heat injures Qi, causing Wei Qi to be unable to resist and retreat, allowing the pathogen to prevail and generate cold. Yang pathogens move fastest; once invading the Wei level, they follow the movement of Wei Qi and transform into heat within the Wei level. The source of the disease is at the Wei level, initially causing no damage to the original Yin and Ying (Nutritive) levels. However, if it lingers in the Wei level without being expelled, wind dominance leads to tremors/movement, and heat dominance leads to swelling. Thus, Yang hyperactivity consumes Yin, burning and damaging the Ying level. Therefore, dispersing (Shu Da) and nourishing Yin cannot be neglected; this is the second reason why the Double Resolution method should be applied. Furthermore, if at the onset there is mental dullness, faint sand points (Sha Dian), dry heat, and rotting throat, with a fierce onset, failing to clearly identify the syndrome and attempting treatment with small doses is tantamount to indecision and nurturing evil, inevitably leading to major disasters. This is like using a cup of water to extinguish a cartload of firewood—it only increases the flames.
