《原病式》曰∶凡人初觉发背，背欲结未结，赤热肿痛，先用湿纸复其上，立候之，其
纸先干处，即是结，痈头也。取大蒜切成片，如三铜钱浓，安于头上，用大艾炷灸三壮，即
换一蒜片，痛者灸至不痛，不痛灸至痛时，方住。最要早觉早灸，若一日二日，十灸七活；
三日四日，六七活；五日六日，三四活。过七日，则不可灸。若有十数头作一处生者，即用
大蒜研成膏，作薄饼铺其上，聚艾于蒜饼上烧之，亦能活也。若背上初发赤肿一片，中间有

而止，谓先及其 ，所以不痛，次及良肉，所以痛也。此痈疽初发之治也。
若诸疮患久成漏者，常有脓水不绝，其脓不臭，内无歹肉，尤宜用附子浸透，切作大片

作饼子，浓约三分，于疮上用艾灸二十一壮，一灸一易饼子，后四五日，方用翠霞锭子，并
信效锭子，互相用之， 入疮内，歹肉尽去，好肉长平，然后外贴收敛之药，内服应病之剂

《原病式》中说：凡是人刚开始觉得背部发背痈，背部肿块将要形成但尚未完全结聚时，出现红肿热痛的症状，先用湿纸覆盖在患处，立即观察，纸上最先变干的地方，就是肿块结聚之处，也就是痈头。取大蒜切成片，厚度如同三枚铜钱叠在一起，放在痈头上，用大艾炷灸三壮，然后换一片蒜片，如果患者感到疼痛，就灸到不痛为止；如果不痛，就灸到有痛感时停止。最重要的是尽早察觉并尽早施灸，如果发病一两天内施灸，十个能救活七个；发病三四天内施灸，能救活六七个；发病五六天内施灸，能救活三四个。超过七天，就不能再施灸了。如果有十几个痈头聚集在一起生长，就用大蒜研成膏状，做成薄饼铺在上面，将艾绒聚集在蒜饼上烧灼，也能救活。如果背上初起时是一片赤肿，中间有一个凹陷处。又说：对于疼痛的，灸到不痛为止，意思是先灸及未溃破之处，所以会痛；其次灸及即将溃破之处，所以不痛。对于不痛的，灸到有痛感为止，意思是先灸及已坏死之处，所以不痛，其次灸及健康肌肉，所以会痛。这是治疗痈疽初发的方法。
如果各种疮疡患病日久形成瘘管，常有脓水不断流出，脓液没有臭味，内部没有腐肉，特别适宜用附子浸泡透后，切成大片，厚度两三分，放在疮口上艾灸，同时服用内托药。隔两三天再灸一次，不超过五七次，自然肌肉就会长满愈合。至于有脓水恶物、逐渐溃烂且根深蒂固的情况，郭氏治疗时用白面、硫黄、大蒜三样东西一起捣烂，根据疮口大小，捏成饼状，厚度约三分，放在疮口上用艾灸二十一壮，每次灸完更换一个饼子，四五天后，再用翠霞锭子和信效锭子，交替使用，插入疮口内，使腐肉全部去除，好肉长平，然后外贴收敛药物，内服对症药剂，调理后即可痊愈。
The *Yuan Bing Shi* (Treatise on the Original Causes of Disease) states: When a person initially feels the onset of a carbuncle on the back, and the swelling is about to form but has not yet fully consolidated, presenting with redness, heat, swelling, and pain, first cover the affected area with wet paper and observe immediately. The place where the paper dries first indicates the site of consolidation, which is the head of the abscess. Take garlic, slice it to a thickness equivalent to three stacked copper coins, place it on the head of the abscess, and moxibustion with a large moxa cone for three *zhuang*. Then replace with a new garlic slice. If the patient feels pain, continue moxibustion until the pain ceases; if there is no pain, continue until pain is felt, then stop. It is most crucial to detect and treat early. If treated within one or two days of onset, seven out of ten cases can be saved; within three or four days, six or seven out of ten; within five or six days, three or four out of ten. After seven days, moxibustion is no longer effective. If several heads of the abscess grow together in one area, grind garlic into a paste, make it into a thin cake, spread it over the area, and gather moxa on top of the garlic cake to burn. This can also save the patient. If the back initially presents as a patch of redness and swelling with a depression in the center. It is also said: For painful lesions, moxibustion should be continued until the pain stops. This means treating the un-ulcerated area first, which causes pain; then treating the area about to ulcerate, which does not cause pain. For non-painful lesions, moxibustion should be continued until pain is felt. This means treating the necrotic area first, which does not cause pain; then treating the healthy flesh, which causes pain. This is the treatment method for the initial stage of carbuncles and sores.
If various sores have persisted for a long time and formed fistulas, with continuous discharge of pus that is odorless and without internal necrotic tissue, it is particularly suitable to use *Fuzi* (Aconiti Lateralis Radix Praeparata) soaked thoroughly, sliced into large pieces of 2-3 fen thickness, placed on the sore for moxibustion, while simultaneously administering internal supportive herbs (*Neituo* medicine). Repeat moxibustion every two or three days. Within five to seven sessions, the flesh will naturally fill in and heal. In cases with foul-smelling pus and deep-rooted progressive ulceration, Guo's treatment method involves pounding together white flour, sulfur, and garlic. Based on the size of the sore, shape this mixture into a cake approximately 3 fen thick, place it on the sore, and perform twenty-one *zhuang* of moxibustion. Replace the cake after each session. After four or five days, apply *Cuixia Dingzi* (Emerald Cloud Pill) and *Xinxiao Dingzi* (Faithful Efficacy Pill) alternately, inserting them into the sore to remove all necrotic tissue until healthy flesh grows flat. Then, apply external astringent medicines externally and administer internal remedies corresponding to the disease condition. With proper regulation, the patient will recover.
