治青腿牙疳。
用青白马乳，早午晚随挤随服甚效。如无青白马，杂色马亦可。若马乳自他处取来，可将碗置于开水盆中温之。
此方出于《医宗金鉴》，其原注云∶此证自古方书罕载其名，仅传于雍正年间。陶起麟谓∶凡病腿肿色青
者，其上必发牙疳，凡病牙疳腐血者，其下必发青腿，二者相因而至。推其病原，皆因上为阳火炎炽，下为阴
寒闭郁，以至阴阳上下不交，各自为寒为热，凝结而生此证也。相近内地亦间有之，边外虽亦有，而不甚多，
惟内地人初居边外，得此证者十居七八。盖内地之人，本不耐边外严寒，更不免坐卧湿地，故寒湿之痰生于下，
致腿青肿。其病形如云片，色似茄黑，肉体顽硬，所以步履艰难也。又缘边外缺少五谷，多食牛羊等肉，其热
与湿合蒸，瘀于胃中，毒火上熏，致生牙疳。牙龈浮肿出血，若穿腮破唇，腐烂色黑，即为危候。惟相传有服
马乳之法，用之颇有效验云云。
按∶此证愚未见过，友人毛××曾遇此证治愈。其方愚犹记其大概，爰列于下，以备采用。
金银花（五钱） 连翘（三钱） 菊花（三钱） 明乳香（四钱） 明没药（四钱） 怀牛膝（五钱）
山楂片（三钱） 真鹿角胶（四钱，捣为细末分两次用头煎二煎汤药送服）
按此方若服之出汗，即可见愈。然方中连翘、菊花发汗之力甚微，恐服之不能出汗，当于服药之后，再服
西药阿斯匹林一瓦，则无不出汗矣。至汗后服第二剂时，宜将菊花减半。
治疗青腿牙疳。
使用青色或白色的马奶，早晚午三次随挤随喝，效果很好。如果没有青白马，杂色马也可以。如果马奶是从别处取来的，可以将碗放在开水盆中温热后服用。
此方出自《医宗金鉴》，其原注说：这种病症自古以来在医书中很少记载其名，仅在雍正年间流传。陶起麟说：凡是腿部肿胀发青的病，其上必然发生牙疳；凡是患牙疳且伴有腐血病的，其下必然发生青腿，这两种病是相互关联而发生的。推究其病因，都是因为上部阳火炽盛，下部阴寒闭郁，导致阴阳上下不能交通，各自形成寒热，凝结而产生此证。靠近内地的地方偶尔也有，边远地区虽然也有，但不太多，只有内地人刚搬到边远地区居住，得此病的占十分之七八。大概是因为内地的人本来就不适应边远地区的严寒，再加上难免坐卧湿地，所以寒湿之痰生于下部，导致腿部发青肿胀。其病形像云片，颜色像茄子黑，肌肉坚硬，所以行走困难。又因为边远地区缺少五谷，多吃牛羊等肉类，热气与湿气结合蒸腾，瘀滞在胃中，毒火上熏，导致产生牙疳。牙龈浮肿出血，如果穿腮破唇，腐烂发黑，就是危重的征候。只有相传有服用马奶的方法，使用它颇有疗效。
按语：这种病症我未曾见过，朋友毛××曾遇到并治愈了此证。这个方子我还记得大概，于是列在下面，以备采用。
金银花（五钱） 连翘（三钱） 菊花（三钱） 明乳香（四钱） 明没药（四钱） 怀牛膝（五钱）
山楂片（三钱） 真鹿角胶（四钱，捣成细末分两次用头煎和二煎的药汤送服）
按：此方如果服用后出汗，就可以见到痊愈。然而方中的连翘、菊花发汗的力量很微弱，恐怕服用后不能出汗，应当在服药之后，再服用西药阿斯匹林一瓦，这样就没有不出汗的了。至于出汗后服用第二剂时，应该将菊花减半。
Treating Qing Tui Ya Gan (Green Leg and Gum Rot).
Use mare's milk from a green or white horse, drinking it fresh as soon as it is milked three times a day (morning, noon, and evening); this is very effective. If no green or white horses are available, horses of mixed colors may also be used. If the mare's milk is obtained from elsewhere, the bowl can be warmed by placing it in a basin of hot water before consumption.
This prescription originates from *Yi Zong Jin Jian* (Golden Mirror of Medicine), whose original annotation states: "The name of this condition is rarely recorded in ancient medical texts; it was only transmitted during the Yongzheng reign period." Tao Qilin stated: "For any case where the legs swell and turn blue/green, gum rot (Ya Gan) must necessarily develop above; for any case of gum rot accompanied by putrid blood, green leg (Qing Tui) must necessarily develop below. These two conditions arise sequentially from one another." Inferring the etiology, both result from excessive blazing of Yang Fire in the upper body and closure/depression of Yin Cold in the lower body, leading to a failure of communication between Upper and Lower Yin and Yang. They independently generate cold and heat, condensing to produce this condition. It occasionally occurs in areas near the interior regions, and although it exists in border regions, it is not very common. However, among people from the interior who have just moved to live in border regions, seven or eight out of ten suffer from this condition. This is likely because people from the interior are inherently intolerant to the severe cold of the border regions, and furthermore, they inevitably sit or lie on damp ground. Consequently, phlegm generated from Cold-Dampness arises in the lower part, causing the legs to turn blue/green and swell. The appearance of the disease resembles cloud patches, the color is like dark eggplant black, the flesh is hard and stiff, making walking difficult. Additionally, due to the scarcity of grains in border regions, people consume large amounts of mutton and beef. The heat combines with dampness and steams upward, stagnating in the Stomach. Toxic fire flares up, causing gum rot. The gums become swollen and bleed; if the cheeks perforate or lips break, and the tissue rots and turns black, it indicates a critical prognosis. Only through tradition is there knowledge of the method of consuming mare's milk, which proves quite effective.
Note: I have never personally encountered this condition. My friend Mao XX once treated and cured a patient with this condition. I still recall the general outline of this prescription, so I list it below for reference.
Jinyinhua (Honeysuckle Flower) [5 qian], Lianqiao (Forsythia Fruit) [3 qian], Juhua (Chrysanthemum Flower) [3 qian], Ming Ruxiang (Frankincense) [4 qian], Ming Moyao (Myrrh) [4 qian], Huai Niuxi (Achyranthes Root) [5 qian], Shanzha Pian (Hawthorn Slice) [3 qian], Zhen Lu Jiao Jiao (Deer Antler Glue) [4 qian, pounded into fine powder, taken in two doses, washed down with the decoction from the first and second brews].
Note: If this prescription induces sweating upon administration, recovery will be evident. However, the diaphoretic power of Lianqiao and Juhua in this formula is very weak, so it is feared that sweating may not occur. After taking the medicine, one should take one grain of Aspirin (Western medicine), then sweating will certainly occur. When taking the second dose after sweating has occurred, the dosage of Juhua should be halved.
