凡阴疽及鬼邪着人，或两眼内障，此三法皆出《内经》。其疮疽本于肾虚，为阴所着，寒邪滞经，根据附于
骨，故烂人筋，害人性命。其法必大补肾气，壮阳消阴，土得阳气，自生肌肉，则元气周流不侵骨髓矣。今则
附入外科，庸医不知，反用败毒凉药，致元气虚惫而死者，多矣。（亲见一妇人患伏免阴疽，形扁色白，大如
覆盂，延一艮山门疡医，连用清火败毒药四剂，不待脓溃，一泻而死。）
鬼邪着人者，皆由阴盛阳虚，鬼能根据附阴气，故易而成病，若阳光盛者焉敢近之。治法大补元气 加以育
神，则鬼邪自然离体。病家不知，专求符 ，此等外道决无灵验。或假手庸医，认为燥火，投以凉药，或清热
化痰，致人枉死，良可悲哉。（世俗于轻浅小疾皆事巫祝，况鬼祟为殃，肯舍巫 乎！加之医用寒凉，故尔愈者不易。）
眼生内障由于脾肾两虚，阳光不振耳。故光之短主于脾，视物不明主乎肾。法当温补脾肾，壮阳光以消
阴翳，则目明矣。今则另立眼科以成一家之技，只用凉剂，冰损元阳，致脾肾虚衰而死，殊不知一切病证皆有
《内经》正法。后人分立十三科妄名，是以识见小者，专习一科，成一偏之见，譬之大海中认一浮沤，综理未
贯，动即伤生，悲哉！（予目睹京中来一太医院官陈某，自炫能开瞽目，专以冷水冰伏，又以寒膏内陷。其人
本领，实而火重者见效亦捷；若本弱元亏者，无不阴受其害。斜桥一盐贩之妻服膏半盏，腹即 痛，其夫强之
服尽，大吐而毙。其夫一时惶急，从楼窗跃出街心。哭叫∶陈太医药杀我妇！百种辱骂累及祖先，闻者无不寒
心。笔此以见寒凉误人，并信耳不信目之戒。）
凡是阴疽（一种发于阴分的疮疡，漫肿无头，皮色不变）以及鬼邪（指外感邪气或精神因素导致的怪病）侵袭人体，或者两眼出现内障（晶状体混浊等内部眼疾），这三种病症的治疗方法都出自《黄帝内经》。那些疮疽本源于肾气虚弱，被阴寒之邪所侵，寒邪停滞在经络中，依附于骨骼，因此会腐蚀人的筋脉，危害性命。治疗这类疾病必须大补肾气，壮阳以消除阴寒，就像大地得到阳气后自然能生长肌肉一样，这样元气就能周流全身而不被骨髓侵蚀。如今这些疗法却被归入外科范畴，庸医不懂此理，反而使用败毒和寒凉的药物，导致患者元气虚极衰竭而死的情况非常多。（我亲眼见到一位妇人患伏兔穴部位的阴疽，患处平坦、颜色苍白，大小如倒扣的盂，她去找艮山门的一位外科医生诊治，连续用了四剂清火败毒的药，还没等到化脓，就因腹泻而死亡。）
所谓鬼邪侵袭人体，都是由于阴气过盛、阳气虚弱所致，鬼邪能够依附于阴气，所以容易致病，如果是阳气旺盛的人，鬼邪怎敢靠近。治疗方法应当大补元气，并加以安神定志，那么鬼邪自然会离开身体。病人家属不懂这个道理，专门寻求符咒驱邪，这种旁门左道绝对没有灵验。或者假手庸医，误认为是燥火，投用寒凉药物，或者清热化痰，导致人无辜丧命，实在令人悲哀。（世俗之人对于轻微的小病都去求助于巫祝，何况是鬼祟作怪，怎么会舍弃巫祝呢！加上医生多用寒凉药物，所以治愈者不容易。）
眼睛生内障是由于脾肾两虚，阳光（指阳气）不振所致。所以视物短促主要与脾有关，视物不明主要与肾有关。治法应当温补脾肾，壮大阳气以消除阴翳（眼中的遮蔽物），眼睛就能明亮了。如今却另立眼科以形成一家之技，只用寒凉药剂，冰伏损伤元阳，导致脾肾虚衰而死，殊不知所有的病证都有《黄帝内经》的正法。后人分立十三科妄加名称，因此见识浅薄的人，专门研习一科，形成偏颇的见解，这好比在大海中只认识一个水泡，综合管理未能贯通，动不动就伤害生命，可悲啊！（我目睹从京城来了一位太医院官员陈某，自夸能治好盲人，专门用冷水冰伏，又用寒膏使病情内陷。这个人对于体质实热、火气重的人见效也快；但如果原本体弱元气亏损的人，无不受到阴寒的伤害。斜桥一位盐贩的妻子服用了半盏药膏，腹部立刻疼痛，她的丈夫强迫她服完，结果剧烈呕吐而死。她的丈夫一时惊慌焦急，从楼窗跳到了街心，哭喊着：“陈太医药杀了我的妻子！”各种辱骂牵连到祖先，听到的人无不感到寒心。记录此事是为了说明寒凉药物误人，以及警示人们要相信亲眼所见而非仅信耳闻。）
Whenever Yin abscesses (a type of ulcer originating from the Yin aspect, characterized by diffuse swelling without a head and unchanged skin color) or "ghost pathogens" (pathogenic factors or mental influences causing strange diseases) invade the human body, or when internal cataracts (internal eye diseases such as lens opacity) appear in both eyes, the treatment methods for these three conditions all originate from the *Huangdi Neijing* (Yellow Emperor's Inner Canon). These ulcers are fundamentally caused by Kidney deficiency, invaded by Yin-cold pathogens. The cold pathogens stagnate in the meridians and adhere to the bones, thereby rotting the tendons and endangering life. The treatment must strongly tonify Kidney Qi, strengthen Yang to eliminate Yin-cold. Just as the earth naturally generates muscle tissue upon receiving Yang Qi, the Yuan Qi (Original Qi) will circulate throughout the body without being invaded by the bone marrow. Nowadays, these methods have been incorrectly categorized under Surgery. Quack doctors, unaware of this principle, instead use detoxifying and cooling medicines, leading to many deaths due to extreme depletion of Yuan Qi. (I personally witnessed a woman suffering from a Yin abscess at the Futu point [ST32]. The lesion was flat, pale in color, and as large as an inverted bowl. She consulted a surgical doctor at Genshan Gate who administered four doses of fire-clearing and detoxifying drugs. Before suppuration could occur, she died from diarrhea.)
The invasion of "ghost pathogens" into the human body is always due to excessive Yin and deficient Yang. Ghosts can adhere to Yin Qi, making illness easy to develop; however, if the Sunlight (Yang Qi) is abundant, how would they dare approach? The treatment method involves strongly tonifying Yuan Qi and adding spirit-nourishing techniques, after which the ghost pathogens will naturally leave the body. Families ignorant of this principle specifically seek talismans and spells; such heterodox practices are absolutely ineffective. Or, they entrust quack doctors who misdiagnose the condition as dryness-fire, administering cooling medicines, or clearing heat and resolving phlegm, resulting in unjustified death, which is truly lamentable. (In secular society, people resort to shamans and diviners even for minor ailments; how much more so for disasters caused by ghosts! Furthermore, since doctors often use cold and cooling remedies, it is not easy for patients to be cured.)
Internal cataracts arise from the deficiency of both Spleen and Kidney, resulting in the failure of Sunlight (Yang Qi) to flourish. Therefore, short-sightedness is primarily governed by the Spleen, while blurred vision is primarily governed by the Kidney. The method should be to warm and tonify the Spleen and Kidney, strengthen Yang Qi to eliminate Yin shadows (obscurations in the eye), and thus restore clear vision. Nowadays, Ophthalmology has been established separately to form a specialized skill, using only cooling prescriptions. This freezes and damages Yuan Yang, leading to death from Spleen and Kidney deficiency. They fail to realize that all disease patterns have orthodox methods in the *Huangdi Neijing*. Later generations arbitrarily divided medicine into thirteen departments with false names. Consequently, those with limited knowledge specialize in one department, forming biased views. This is like recognizing only a single bubble in the vast ocean; lacking comprehensive management, such actions easily cause harm to life. How sad! (I witnessed a certain Official Chen from the Imperial Medical Bureau coming from the capital, boasting of his ability to restore sight to the blind. He specifically used cold water to freeze the condition and applied cold ointments to drive the pathology inward. For individuals with strong constitutions and heavy fire, his effects were rapid; however, for those with weak constitutions and depleted Yuan Qi, none escaped the harm of Yin-cold. A salt vendor's wife in Xieqiao took half a cup of the ointment and immediately suffered abdominal pain. Her husband forced her to finish it, resulting in severe vomiting and death. In a panic, her husband jumped from a window onto the street, crying out: "Official Chen's medicine killed my wife!" He cursed extensively, implicating ancestors, causing all who heard it to shudder. I record this to demonstrate how cooling medicines harm people and to warn against trusting hearsay over direct observation.)
