痧毒不尽，留滞肌肉腠理之间，即成肿毒。宜先放痧，用散痧解毒之药，以除其根。然后审其毒之所发，照十二经
络脏腑，分阴阳寒热处治。轻则消之，重则托之，虚则补之，实则泻之。若红肿甚者，属阳，用忍冬解毒汤，加引经
药以治之。白色不红，平肿不易起发者，属阴，用参归化毒汤，加引经药以托之。毒有半阴半阳，用活络透毒饮，加引
经药透之。穿破之后，皆用神仙太乙膏贴之。若肿毒无脓，止有毒水流出，或脓少血多，用飞龙夺命丹，研碎些须，填
太乙膏中，拔去毒水血脓后，单用太乙膏贴之。毒口难收，用红肉散掺之。肉黑者，用代刀散，以棉花絮微掺之，即变
红色，贴膏自愈。
治验∶
一姜云衢遍身疼痛，背发一毒，黑烂痛苦。求余视，诊之，脉沉微，指头黑色而恶热饮，此痧变恶毒，用冷围药而
成背疽也。令去其围药，放痧讫，俟痧气已绝，用参 姜桂熟附子温托之，外敷以代刀散，黑变红色，贴太乙膏而痊。
一苏成中长子，暑月吐泻，腹中绞痛，刮痧痛止，两臂红肿且痒。求余一方，用香薷饮一剂而痊。
一葛弘先内室痧痛，不吐不泻，盘肠绞绞，疼痛难忍，放痧后，头顶生毒，出脓而愈。
一赵公琰，寒热头眩，心胸烦闷，刮痧而愈。肛门边发
余毒出脓成漏，为终身之疾。
痧毒未能清除，滞留于肌肉与腠理之间，就会形成肿毒。应当先进行放痧治疗，使用具有散痧解毒功效的药物，以去除病根。然后审查毒邪发作的部位，依据十二经络和脏腑理论，分辨阴阳寒热性质进行治疗。病情轻的采用消散法，病情重的采用托毒外出法，正气虚的采用补益法，邪气实的采用泻法。如果红肿严重的，属于阳证，使用忍冬解毒汤，加入引经药来治疗。颜色发白且不红，肿胀平坦不易溃破的，属于阴证，使用参归化毒汤，加入引经药来托毒。毒邪性质介于半阴半阳之间的，使用活络透毒饮，加入引经药来透达毒邪。疮口穿破之后，均使用神仙太乙膏外贴。如果肿毒没有脓液，只有毒水流出，或者脓少血多，使用飞龙夺命丹，研磨少许，填入太乙膏中，拔出毒水和血脓后，单独使用太乙膏外贴。毒口难以愈合收敛的，使用红肉散掺敷。患处肌肉发黑的，使用代刀散，用棉花絮轻轻掺敷，即可变为红色，贴上膏药即可自愈。
医案验证：
有一位名叫姜云衢的患者，全身疼痛，背部生出一个毒疮，黑色腐烂，痛苦不堪。请求我诊治，诊察发现脉象沉微，指尖发黑且厌恶热饮，这是痧毒转化为恶毒，因使用冷性围药而导致的背疽。命令他去掉冷性围药，放痧结束后，待痧气完全消除，用人参、干姜、桂枝、熟附子温补托毒，外部敷上代刀散，黑色变为红色，贴上太乙膏后痊愈。
苏成的长子，在暑天出现呕吐腹泻，腹部绞痛，刮痧后疼痛停止，但双臂红肿且瘙痒。请求我开一方剂，服用一剂香薷饮后痊愈。
葛弘先的妻子患痧痛，不吐不泻，肠内绞痛，疼痛难忍，放痧后，头顶生出毒疮，出脓后痊愈。
赵公琰，忽冷忽热，头晕目眩，心胸烦闷，刮痧后痊愈。但肛门边残留余毒，出脓形成瘘管，成为终身疾病。
If the sha toxin is not completely cleared and remains stagnant between the muscles and couli (interstices), it will form a swelling and toxicity. One should first perform sha release therapy, using herbs that disperse sha and detoxify to eliminate the root cause. Then, examine where the toxin manifests, and according to the twelve meridians and zang-fu organs, differentiate yin and yang, cold and heat for treatment. For mild cases, use resolution; for severe cases, use expulsion/support; for deficiency, use tonification; for excess, use purgation. If redness and swelling are severe, it belongs to Yang syndrome; use Ren Dong Jie Du Tang (Honeysuckle Detoxification Decoction) with channel-directing herbs for treatment. If the color is white without redness, and the swelling is flat and difficult to erupt, it belongs to Yin syndrome; use Shen Gui Hua Du Tang (Ginseng and Angelica Toxin-Transforming Decoction) with channel-directing herbs to support expulsion. If the toxin is half-Yin and half-Yang, use Huo Luo Tou Du Yin (Collateral-Activating Toxin-Expelling Drink) with channel-directing herbs to penetrate and expel. After the abscess ruptures, apply Shen Xian Tai Yi Gao (Immortal Taiyi Plaster). If there is no pus but only toxic fluid oozing out, or if there is little pus and much blood, use Fei Long Duo Ming Dan (Flying Dragon Life-Seizing Pill), grind a small amount, mix into the Taiyi plaster, extract the toxic fluid and bloody pus, then apply the Taiyi plaster alone. If the wound is difficult to heal and close, sprinkle Hong Rou San (Red Flesh Powder). If the flesh is black, use Dai Dao San (Knife-Replacement Powder), lightly sprinkle with cotton wool, which will turn red, and apply the plaster for self-healing.
Clinical Cases:
Jiang Yunqu suffered from whole-body pain and developed a toxic sore on his back, which was black, ulcerated, and painful. Upon examination, his pulse was deep and faint, his fingertips were black, and he disliked hot drinks. This indicated that sha had transformed into malignant toxin, resulting in a carbuncle of the back due to the application of cold compresses. He was instructed to remove the cold compresses. After sha release was completed and the sha qi dissipated, he was treated internally with Ginseng, Zingiberis Rhizoma Recens (Dried Ginger), Cinnamomi Ramulus (Cinnamon Twig), and Aconiti Lateralis Radix Praeparata (Prepared Forked Root of Chinese Aconite) to warm and support the body. Externally, Dai Dao San was applied. The blackness turned red, and after applying Taiyi plaster, he recovered.
The eldest son of Su Cheng suffered from vomiting and diarrhea during the summer months, accompanied by colicky abdominal pain. After scraping therapy, the pain ceased, but his arms became red, swollen, and itchy. A prescription of Xiang Ru Yin (Elsholtzia Decoction) was administered for one dose, leading to recovery.
The wife of Ge Hongxian suffered from sha pain without vomiting or diarrhea, experiencing severe intestinal cramping and unbearable pain. After sha release, a toxic sore appeared on the top of her head, which healed after draining pus.
Zhao Gongyan experienced alternating chills and fever, dizziness, and mental restlessness. He recovered after scraping therapy. However, residual toxin manifested near the anus, forming a fistula with pus discharge, resulting in a lifelong ailment.
