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。

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.
