Various chronic sores that have persisted for a long time often present with continuous discharge of pus and fluid. The pus is not foul-smelling, and there is no necrotic tissue inside. In such cases, one must first administer a large dose of a formula containing Ren Shen (Ginseng), Dang Gui (Angelica Sinensis), and Bai Zhu (Atractylodes Macrocephala) to primarily support the interior and expel toxins, or take it in pill form. It is particularly suitable to use Fu Zi (Aconite Lateralis Radix Praeparata) that has been thoroughly soaked, sliced into pieces approximately 2-3 fen thick, placed on the sore, and moxibusted. Continue taking the aforementioned interior-supporting medicine. Moxibustion should be performed every three days; after five to seven sessions, the muscle tissue will naturally grow to fill the wound.

In cases where pus and foul matter gradually ulcerate with a deep root, mix flour, Liu Huang (Sulfur), and Da Suan (Garlic Bulb) together until mashed. Shape the mixture into a cake approximately 3 fen thick, according to the size of the sore, place it on the lesion, and apply moxa cones for twenty-one burns (zhuang), replacing the cake after each burn. After four to five days, insert Cuixia Dingzi (Emerald Cloud Pill) and Xinxiao Dingzi (Trustworthy Effect Pill) into the sore. Once all necrotic tissue is removed and healthy flesh grows flat, apply astringent medicines externally and administer internal remedies tailored to the disease, regulating the patient until recovery.

Luo Qianfu stated: A patient suffered from redness and swelling of the head and eyes, severe heat in front of the ears, unbearable pain, fever, aversion to cold, trismus (lockjaw), thick and sticky sputum and nasal discharge, difficulty swallowing, and inability to sleep peacefully. A surgeon used Bian Shi (Bian Stone) to puncture the hardened area, inserting several hundred needles, yet the redness and swelling did not decrease, and the pain intensified. The cause was unknown. Upon palpation, the pulse was floating and tight, but forceful pressure revealed a surging and slow quality. This indicates cold covering the skin and hair, stagnating and blocking the meridians, preventing heat from ascending, leading to accumulation and resulting in redness and swelling. The Classic states: When heaven is cold and earth frozen, water turns to ice; human qi resides within, the skin is dense, pores are closed, sweat does not emerge, blood and qi are strong, and the interior is firm and full. At this time, even those skilled in managing water cannot flow it, those skilled in digging cannot pierce the frozen ground, and those skilled in acupuncture cannot treat tetraplegia (Si Jue). One must wait for warm weather, when ice melts and frost dissolves, allowing water to flow and earth to be dug; similarly, human meridians follow this principle. It is also said: In winter, storage is closed, water freezes, and earth cracks; therefore, when using medicine, needle and stone therapies are frequently employed. One should use bitter-warm agents to warm the meridians and scatter cold, establishing the winning qi (healthy qi), slightly using bitter herbs to vent, and slightly using acrid herbs to disperse. Ma Huang (Ephedrae Herba) is a bitter-warm herb for venting; Fang Feng (Saposhnikoviae Radix) is an acrid-warm herb for dispersing; Sheng Ma (Cimicifugae Rhizoma) is bitter and acrid; Ge Gen (Puerariae Lobatae Radix) and Gan Cao (Glycyrrhizae Radix et Rhizoma) resolve the muscle layer and induce sweating, specifically treating pathogens in the Yangming Meridian, thus serving as Deputy Ministers. When blood flows but does not circulate smoothly, pain occurs; therefore, add small amounts of Bai Zhi (Angelicae Dahuricae Radix), which is acrid and warm, and Dang Gui (Angelicae Sinensis Radix) to harmonize blood and dissipate stasis. Damp-heat causes swelling; Cang Zhu (Atractylodis Rhizoma), being bitter and sweet, can drain damp-heat from the skin and pores. Ren Shen (Ginseng Radix) and Gan Cao (Glycyrrhizae Radix et Rhizoma) are sweet and warm; Bai Shao Yao (Paeoniae Radix Alba) is sour and cold; together they harmonize the middle, boost qi, and tonify the interior, thus serving as Assistants. Decoct and administer according to method: cover the head with thin clothing and the body with thick blankets. If the sleeping environment is warm, the meridian blood becomes warm, pores open, cold scatters, yang qi ascends, and the swelling reduces by eight or nine tenths. For the second administration, remove Ma Huang (Ephedrae Herba) and Fang Feng (Saposhnikoviae Radix), add Lian Qiao (Forsythiae Fructus) and Niu Bang Zi (Arctii Fructus), and the pain will completely cease. The Classic states: "Inducing sweating cures sores," which is indeed true.
