烂孔有恶肉凸起，名曰毒根，往往有用降药烂去者，此乃殴之速毙也。独不知弱体岂可
增痛
，况烂去仍又长出，安可再烂？余所制平安饼，专贴毒根，外以阳和解凝膏贴掩，一日一易
，轻者二三日，重者六七日，不痒不痛，毒根自落。贴饼时，日服托毒散，俟毒根落后，当
服保元、四物二汤收功。
马曰∶此症乃疮中有火所致，不若用铜绿 研极细，陈去火毒掺之，上用膏盖，可以平
也。
溃久不敛，必至翻花起肛坚硬，取老蟾破腹连肚杂，以蟾身刺数孔，贴患口上，轻者日
易一
次，重者日易两次。贴蟾之日，日服醒消丸三钱，陈酒送服，止其疼痛，三日后毒尽，再服
醒消丸，消其翻花，软其硬肛。如大患初溃者，亦如前法，毒从蟾孔而出。倘肛口硬、患孔
深，取活牛蒡草根、枝、叶，或取紫花地丁草软者，捣烂涂入肛内，拔毒平肛，功效不凡。
马曰∶此症用蟾破贴颇效。
凡受降药之毒，定致神昏呕吐，此系毒瓦斯攻心，急用护心散，以生甘草一两，煎浓汁稠
调，令病者时刻呷咽，咽至大半，自然止呕，神气清爽，接服醒消，以平其势。
马曰∶疮毒攻心，亦令神昏呕吐，至于降药之毒，须用人中黄、贯众、绿豆解之最佳。
阴毒之症，皮色皆同，然有肿有不肿，有痛有不痛，有坚硬难移，有柔软如绵，不可不
为之
辨。夫肿而不坚，痛而难忍，流注也。肿而坚硬微痛，贴骨、鹤膝、横 、骨槽等类是也。
不肿而痛，骨骱麻木，手足不仁，风湿也。坚硬如核，初起不痛，乳岩瘰 也。不痛而坚，
形大如拳，恶核失荣也。不痛不坚，软而渐大，瘿瘤也。不痛而坚如金石，形如升斗，石疽
也。此等症候，尽属阴虚，无论平塌大小，毒发五脏，皆曰阴疽。如其初起疼痛者易消，重
按不痛而坚者，毒根深固，消之难速，治之之法，方有一定，学人览之了然。
马曰∶柔软如绵，乃气与痰滞，治宜流气，气行痰即行。流注一名气毒，又名串痰。
又曰∶乳岩、失荣、马刀，乃七情致伤之症，治宜解郁疏肝，不可照阴疽例治。
溃烂的孔洞中有恶性的肉芽凸起，称为“毒根”，往往有人使用腐蚀性药物将其腐蚀去除，这等于逼迫患者迅速死亡。殊不知体质虚弱的人怎能增加痛苦？况且腐蚀去除后仍然会长出来，怎么可以再次腐蚀？我所制作的平安饼，专门贴在毒根上，外部再用阳和解凝膏覆盖贴敷，每天更换一次，轻症两三天，重症六七天，不痒不痛，毒根自然脱落。贴平安饼时，每日服用托毒散，等到毒根脱落后，应当服用保元汤和四物汤两个方剂来收功。
马先生说道：这种病症是疮疡中有火邪所致，不如用铜绿研磨成极细粉末，陈久以去除火毒，撒在患处，上面用膏药覆盖，可以使疮面平复。
溃疡日久不愈合，必然导致疮口翻花、肛部坚硬，取老蟾蜍剖开腹部连同内脏一起捣碎，用蟾蜍身体刺几个孔，贴在患口上，轻症每天更换一次，重症每天更换两次。贴蟾蜍的那天，每日服用三钱醒消丸，用陈年黄酒送服，以制止疼痛，三天后毒气尽除，再服用醒消丸，以消除翻花，软化坚硬的肛部。如果是大疮初溃的情况，也按照前面的方法，毒气从蟾蜍身上的孔洞排出。如果肛口硬、患孔深，取活的牛蒡草根、枝、叶，或者取紫花地丁草中较软的部位，捣烂涂入肛内，拔毒平肛，功效非凡。
马先生说道：此症用剖开的蟾蜍外贴颇为有效。
凡是受到降药（腐蚀性药物）毒害的，必定导致神志昏迷、呕吐，这是毒瓦斯攻心，急用护心散，用生甘草一两，煎煮成浓稠汁液，让病人时刻小口吞咽，咽下大半后，呕吐自然停止，神气清爽，接着服用醒消丸，以平息病势。
马先生说道：疮毒攻心，也会导致神志昏迷、呕吐，至于降药的毒性，必须用人中黄、贯众、绿豆来解毒最佳。
阴毒的病症，皮肤颜色都相同，但有肿有不肿，有痛有不痛，有坚硬难移，有柔软如棉，不可不加以辨别。肿胀但不坚硬，疼痛难以忍受，是流注病。肿胀且坚硬微痛，是贴骨疽、鹤膝风、横痃、骨槽风等类疾病。不肿而痛，骨节麻木，手足无知觉，是风湿病。坚硬如核，初起不痛，是乳岩、瘰疬。不痛而坚硬，形状大如拳头，是恶核、失荣。不痛不坚硬，柔软而逐渐增大，是瘿瘤。不痛而坚硬如金石，形状如升斗，是石疽。这些证候，都属于阴虚，无论平塌还是大小，毒发于五脏，都称为阴疽。如果初起时有疼痛的容易消散，重按不痛而坚硬的，毒根深固，消散难以快速见效，治疗的方法，方剂有一定之规，学习者阅读后便了然于心。
马先生说道：柔软如棉，是气与痰停滞所致，治疗宜行气，气行则痰即行。流注又名气毒，又名串痰。
又说：乳岩、失荣、马刀，是由于七情致病损伤的病症，治疗宜解郁疏肝，不可以照阴疽的例子治疗。
Ulcerated sores with protruding malignant flesh are named "toxic root" (Du Gen, toxic root). Often, corrosive medicines are used to rot them away, which is equivalent to forcing the patient to die quickly. One fails to realize how a weak constitution can endure increased pain? Moreover, if they grow back after being rotted away, how can one rot them again? The Ping'an Bing (Peaceful Cake) I formulated is specifically applied to the toxic root, covered externally with Yanghe Jiebing Gao (Yanghe Resolving Paste), changed once a day. For mild cases, two to three days; for severe cases, six to seven days. Without itching or pain, the toxic root falls off naturally. While applying the cake, Tuodu San (Toxin-Expelling Powder) is taken orally daily. Once the toxic root has fallen off, Baoyuan Tang (Protect the Origin Decoction) and Siwu Tang (Four Substances Decoction) should be taken to conclude the treatment.
Mr. Ma said: This condition is caused by fire pathogen within the sore. It is better to use Tonglü (Malachite Green) ground into an extremely fine powder, aged to remove its fire toxicity, sprinkled on the lesion, and covered with a plaster to flatten the surface.
If an ulcer remains unhealed for a long time, it will inevitably lead to everted flower-like tissue and hardness at the anal region. Take an old toad, cut open its abdomen including the viscera, pierce several holes in the toad's body, and apply it to the affected opening. For mild cases, change once a day; for severe cases, change twice a day. On the day of applying the toad, take Xingxiao Wan (Xingxiao Pill) 3 qian, delivered with aged yellow wine to stop pain. After three days, when the toxin is exhausted, continue taking Xingxiao Wan to eliminate the everted tissue and soften the hardness. If a major sore has just ulcerated, follow the previous method, allowing the toxin to exit through the holes in the toad. If the anal opening is hard and the sore is deep, take fresh roots, branches, and leaves of Arctii Fructus Radix (Niubangzi, burdock root), or soft parts of Violae Herba (Zihua Diding, violet herb), pound them into a paste, and apply inside the anal canal to extract toxin and flatten the area, with extraordinary efficacy.
Mr. Ma said: Applying a cut toad to this condition is quite effective.
Those who have suffered from the toxicity of Jiang Yao (corrosive medicine) will definitely experience delirium and vomiting. This is due to toxic vapors attacking the heart. Urgently use Huxin San (Heart-Protecting Powder): decoct Sheng Gancao (Raw Licorice Root) 1 liang into a thick concentrated juice, let the patient sip it continuously. After swallowing more than half, vomiting will naturally cease, spirit will become clear, and then take Xingxiao Wan to calm the condition.
Mr. Ma said: Sore toxins attacking the heart also cause delirium and vomiting. As for the toxicity of corrosive medicine, it is best to resolve it using Renzhonghuang (Human Excrement Charcoal), Guanzhong (Cyrtomium Rhizome), and Lüdou (Mung Bean).
Yin Du conditions present with similar skin colors, but some are swollen and some are not, some painful and some not, some hard and immovable, some soft like cotton. Differentiation is essential. Swollen but not hard, painfully unbearable, is Liuzhu (Flowing Abscess). Swollen, hard, and slightly painful, includes Tiegu Ju (Bone-Clinging Carbuncle), Hexi Feng (Crane-Knee Wind), Heng Xuan (Transverse Bubo), and Gucao Feng (Bone-Trough Wind). Not swollen but painful, with numbness in joints and insensitivity in limbs, is Fengshi (Wind-Dampness). Hard like a nut, initially painless, is Ruyan (Breast Cancer) and Luoli (Scrofula). Painless but hard, large as a fist, is Ehe (Malignant Nodule) and Shirong (Loss of Glory). Painless, not hard, soft and gradually enlarging, is Yingliu (Goiter). Painless but hard as metal/stone, shaped like a sheng or dou measure, is Shiju (Stone Carbuncle). These syndromes all belong to Yin Deficiency. Regardless of whether flat or large, when toxin erupts from the five zang organs, it is called Yin Ju (Yin Carbuncle). If painful at onset, it is easy to dissipate; if painless upon heavy pressure but hard, the toxic root is deep and solid, making rapid dissipation difficult. The treatment methods and formulas are fixed; students reading this will understand clearly.
Mr. Ma said: Soft like cotton indicates stagnation of Qi and Phlegm. Treatment should focus on moving Qi; when Qi moves, Phlegm moves. Liuzhu is also known as Qi Du (Qi Toxin) or Chuantan (Stringing Phlegm).
Furthermore: Ruyan, Shirong, and Madao (Horse Knife - a type of scrofula) are conditions injured by Seven Emotions. Treatment should focus on resolving depression and soothing the Liver; they cannot be treated according to the Yin Ju example.
