轻清圆健者为天，故首象天；重浊方浓者为地，故足象地；飘腾往来者为云，故气象云
；过流循环者为水，故血象水。天降地升，云胜水流，各宜其性。故万物生而无穷，阳平阴
秘，气行血随，各得其调。故百骸理而有余。反此，则天地不降升，云水不胜流，各不宜其
性矣。反此，则阴阳不平秘，气血不行随，各不得其调矣。故曰∶人身者，小天地也。《难
经》曰∶血为荣，气为卫，荣行脉中，卫行脉外。此血气分而不混，行而不阻也明矣。故如
云腾水流之不相杂也。大抵血气如此，不欲相混，混则为阻，阻则成结，结则无所去还，故
隐起于皮肤之中，遂为疣病。然各随经络而见，疣病自上眼睫而起者，乃手少阴心脉、足厥
阴肝脉，血气混结而成也。初起时，但如豆许。血气衰者，遂止不复长，亦有久止而复长者
。盛者则渐长，长而不已，如杯如盏，如碗如斗，皆自豆许致也。凡治在初，须择人神不犯
之日，大要令病者食饱不饥，先汲冷井水洗眼如冰，勿使气血得行，然后以左手持铜箸，按
眼睫上，右手翻眼皮令转，转则疣肉已突，换以左手大指按之，弗令得动移，复以右手持小
眉刀尖，略破病处，更以两手大指甲捻之令出，则所出者，如豆许小黄脂也。恐出而根不能
断，宜更以眉刀尖断之。以井水再洗，洗后则无恙。要在手疾为巧。事毕须投以防风散结汤
，数服即愈。此病非手法则不能去。何则？为血气初混时，药自可及，病者则不知其为血气
混也。比结，则药不能及矣，故必用手法去。去毕，必又以升发之药散之，药手皆至，庶几
了事。
轻清圆健的是天，所以头部象征天；重浊方正浓厚的是地，所以足部象征地；飘动往来的是云，所以神态象征云；流动循环的是水，所以血液象征水。天之气下降，地之气上升，云气旺盛，水流顺畅，各自顺应其本性。因此万物生长而无穷尽，阳气平和，阴气秘固，气行则血随，各得其调和。因此全身骨骼肢体得以理顺而有余裕。反之，则天地之气不降不升，云水不胜流，各自不能顺应其本性了。反之，则阴阳不平秘，气血不行随，各自不得其调和了。所以说：人身，就是小天地。《难经》说：血为营（营养），气为卫（保卫），营气行于脉中，卫气行于脉外。这血气分开而不混杂，运行而不阻滞是显而易见的。所以就像云腾水流那样不相混杂。大抵血气如此，不希望相互混杂，混杂就会阻滞，阻滞就会结成，结聚则无处去还，所以在皮肤之中隐起，于是成为疣病。然而各随经络显现，疣病从眼睑睫毛处开始的，乃是手少阴心脉、足厥阴肝脉，血气混结而成的。初起时，仅仅像豆子大小。血气衰弱的，就停止不再生长，也有久停之后又生长的。旺盛的则逐渐长大，长个不停，像杯像盏，像碗像斗，都是从豆子大小发展而来的。凡是治疗要在初期，必须选择人神不犯的日子，大体要领是让患者吃饱不饿，先用冷井水洗眼如冰，不要让气血运行，然后用左手持铜筷，按住眼睑睫毛上，右手翻眼皮令翻转，翻转后疣肉已经突出，换用左手大拇指按住它，不让它移动，再用右手持小眉刀尖，略微刺破患处，再用两手的大指甲捻之令其脱出，那么脱出的东西，像豆子大小的黄色脂肪一样。担心脱出而根部不能断除，适宜再用眉刀尖将其切断。用井水再洗，洗后就没有事了。关键在于手法敏捷才算巧妙。事毕必须服用防风散结汤，服几剂即痊愈。此病非手法则不能去除。为什么呢？因为血气初混时，药物自然可以到达，患者却不知道这是血气混杂。等到结聚，药物就不能到达了，所以必须用手法治去。去除完毕后，必然又要用升发之药来疏散，药物和手法都到位，差不多就能了事。
Light, clear, round, and vigorous constitutes Heaven; thus the head corresponds to Heaven. Heavy, turbid, square, and dense constitutes Earth; thus the feet correspond to Earth. Drifting and coming and going constitutes Clouds; thus the spirit/manner corresponds to Clouds. Flowing and circulating constitutes Water; thus the blood corresponds to Water. Heaven's Qi descends, Earth's Qi ascends; Clouds prevail, Water flows; each follows its nature. Therefore, all things grow endlessly, Yang is balanced, Yin is secure, Qi moves and Blood follows, each attaining harmony. Thus, the hundred bones are regulated and there is surplus. Conversely, Heaven and Earth do not descend or ascend, Clouds and Water do not flow effectively, each failing to follow its nature. Conversely, Yin and Yang are neither balanced nor secure, Qi and Blood do not move and follow, each failing to attain harmony. Hence it is said: The human body is a small Heaven and Earth. The *Nan Jing* (Classic of Difficult Issues) states: Blood is Ying (Nutritive Qi), Qi is Wei (Defensive Qi); Ying circulates within the vessels, Wei circulates outside the vessels. This clearly shows that Blood and Qi are separate and not mixed, moving without obstruction. Thus, they are like Clouds rising and Water flowing, not mixing. Generally, Blood and Qi are such that they should not mix; if mixed, they become obstructed; if obstructed, they form knots; if knotted, they have nowhere to go or return, thus emerging hidden within the skin, becoming warts. However, they appear according to the meridians. Warts starting from the eyelashes are formed by the mixing and knotting of Blood and Qi in the Hand-Shaoyin Heart Meridian and Foot-Jueyin Liver Meridian. At the initial stage, they are merely bean-sized. In cases of deficient Blood and Qi, they stop growing; in some cases, after stopping for a long time, they grow again. In robust cases, they gradually enlarge, continuing to grow until they resemble cups, bowls, or buckets, all originating from bean-sized beginnings. Treatment must be initiated early, selecting days when the patient's Shen (Spirit) is not violated. The general principle is to ensure the patient is full and not hungry, then wash the eyes with cold well water as if ice, preventing the movement of Qi and Blood. Then, hold copper chopsticks with the left hand to press on the eyelashes, use the right hand to turn the eyelid inside out so the wart protrudes. Switch to using the left thumb to press it firmly to prevent displacement. Use the tip of a small eyebrow knife held in the right hand to slightly pierce the lesion. Then, use the thumbnails of both hands to pinch and extract it. What is extracted resembles a small yellow fat particle the size of a bean. To fear that the root may not be severed upon extraction, it is advisable to cut it off with the tip of the eyebrow knife. Wash again with well water; after washing, there will be no harm. The key lies in dexterous manual technique. After the procedure, administer Fangfeng Sanjie Tang (Saposhnikovia Decoction for Dissipating Knots). Several doses will lead to recovery. This disease cannot be removed without manual technique. Why? Because when Blood and Qi first mix, medicine can naturally reach the site, but the patient is unaware of this mixing. Once knotted, medicine cannot reach it; thus, manual removal is necessary. After removal, ascending and dispersing medicines must be used. When both medicine and manual technique are applied, the matter can be resolved.
