曾氏曰∶痈疽脓熟，涂以替针丸，疮口自开。古人云，痈疽能杀人，若针药得其宜则
生，失其宜则死，可不慎哉。
愚按∶疮疡之症，若毒瓦斯已结，肿赤炽盛，中央肉死黯黑者，内用托里健脾之剂，外用
乌金膏涂之，则黯处渐低，赤处渐起，至六七日间，赤黯之界，自有裂纹如刀划状，其黯渐
溃。若用铍针利剪，徐去犹好，须使不知疼痛、不见鲜血为善。若脓未流利，宜用针于纹中
引之。若脓水已出，肿痛仍作，乃内筋间隔，亦用针引之。若元气虚弱，误服克伐之剂，患
处不痛，或肉死不溃者，急温补脾胃，亦有复生矣。后须纯补脾胃，庶能收敛？若妄用针刀
去肉出血，使阳随阴散，是速其危也。若脓溃而烦痛未痊，脉洪滑粗散者，真气虚而邪气实
也，为难治。脉微涩迟缓者，邪气虚而真气将复也，为易治。
李氏云∶痈疽有误搽毒药，或针刀开割，疮口不合，不可用涩敛之药。宜用猪蹄汤、北
艾汤间洗，敷贴神异膏，及服内补十宣散、内托黄 丸。
愚按∶经云∶脾主肌肉。脾健则肉自生。然其势炽甚，宜用前药以消其毒，毒将尽宜用
四君汤以养脾（详见附录用药关键）。
内托黄 丸 治针砭所伤，恶寒发热，脓水不止，肌肉不生，疮口不敛。

曾氏说：痈疽脓液成熟后，涂抹替针丸，疮口自然裂开。古人说，痈疽能致人死亡，如果使用针药得当就能生还，使用不当就会死亡，能不谨慎吗？
我按语：疮疡病症，如果毒气已经凝结，红肿炽热旺盛，中央肌肉坏死呈暗黑色，内服托里健脾的药剂，外用乌金膏涂抹，那么暗黑处逐渐平复，红肿处逐渐隆起，到六七天之间，红与黑的交界处，自然出现像刀划一样的裂纹，暗黑处逐渐溃破。如果用铍针利剪，慢慢去除（腐肉）比较好，必须做到患者不知疼痛、不见鲜血才好。如果脓液尚未流利，宜用针在裂纹中引导排脓。如果脓水已流出，肿痛仍然发作，这是内部筋膜间隔阻碍，也用针引导排脓。如果元气虚弱，误服攻伐的药剂，患处不痛，或者肌肉坏死不溃破的，急需温补脾胃，也有重新恢复生机的。之后须纯用药物补益脾胃，才能收敛愈合。如果妄用针刀去除肌肉导致出血，使阳气随阴血消散，这是加速其危险。如果脓液溃破而烦痛未痊愈，脉象洪大滑数且散乱的，是真气虚弱而邪气实盛，属于难治。脉象微细涩滞迟缓的，是邪气虚弱而真气将要恢复，属于易治。
李氏说：痈疽有误擦毒药，或用针刀切开割除，疮口不合拢，不可使用收敛固涩的药物。宜用猪蹄汤、北艾汤交替清洗，敷贴神异膏，以及服用内补十宣散、内托黄芪丸。
我按语：经书说：脾主肌肉。脾脏健运则肌肉自然生长。然而病情势态炽盛，宜用前面的药物以消除毒气，毒气将尽时宜用四君子汤来养脾（详见附录用药关键）。
内托黄芪丸 治疗因针砭所致的损伤，恶寒发热，脓水不止，肌肉不生，疮口不收敛。
黄芪八两 当归（洗净焙干三两） 肉桂（去掉外皮） 木香 沉香 乳香（单独研细各一两） 绿豆末（四两）
以上药物研为细末，用姜汁和绿豆粉糊制作成丸剂，熟开水送服。
我按语：上述病症如果肌肉受伤，而疮口不收敛，用六君子汤，来补益脾胃。如果气虚怕冷，而疮口不收敛，用补中益气汤，来补益脾肺。如果血虚发热，而疮口不收敛，用四物汤加人参、白术，来滋养肝脾。如果脓多而疮口不收敛，用八珍汤，或十全大补汤，来养血补气。经书说：脾主肌肉。如果前面的药物没有见效，只用四君子汤、当归、地黄来补益脾胃。再没见效，就属于命门火衰，急需使用八味丸来壮火生土。如果脉数且口渴的难治，因为真气虚弱而邪气实盛。
Zeng said: When the pus of a carbuncle or ulcer is ripe, applying Tiphen Wan (Needle-Replacing Pill) will cause the wound to open naturally. The ancients said that carbuncles and ulcers can be fatal; if needles and medicines are used appropriately, life is preserved, but if misused, death ensues. Can one not be cautious?
My commentary: In cases of sores and ulcers, if the pathogenic toxins have consolidated, with intense redness and swelling, and the central flesh is necrotic and dark black, internal administration of formulas that support the interior and strengthen the spleen, combined with external application of Wujin Gao (Gold Ointment), will cause the dark areas to gradually flatten and the red areas to gradually rise. By the sixth or seventh day, cracks resembling knife cuts will naturally appear at the boundary between the red and dark areas, and the necrotic tissue will gradually slough off. It is preferable to slowly remove the necrotic tissue using a Pi Zhen (Lancet Needle) and sharp scissors, provided that the patient feels no pain and no fresh blood is seen. If the pus is not yet flowing freely, it is appropriate to use a needle to guide drainage through the cracks. If pus has drained but swelling and pain persist, this indicates obstruction by internal fascia; again, needle guidance should be used. If the primordial qi is deficient and offensive/depleting medicines were mistakenly taken, resulting in a painless lesion or necrotic flesh that does not ulcerate, urgent warming and tonification of the spleen and stomach is required, and recovery is possible. Subsequently, pure tonification of the spleen and stomach is necessary to facilitate healing. If one recklessly uses needles and knives to remove flesh causing bleeding, dispersing yang following yin, this accelerates danger. If after ulceration, vexation and pain persist, and the pulse is surging, slippery, coarse, and scattered, this indicates deficiency of true qi and excess of pathogenic factors, making it difficult to treat. If the pulse is faint, choppy, slow, and delayed, this indicates deficiency of pathogenic factors and the impending recovery of true qi, making it easy to treat.
Li said: In carbuncles and ulcers, if poisonous drugs were mistakenly applied, or if needles and knives were used for incision, and the wound fails to close, astringent and收敛 (astringent/healing) medicines should not be used. It is advisable to wash alternately with Pig Trotter Decoction and Northern Mugwort Decoction, apply Shenyi Gao (Miraculous Efficacy Ointment), and administer Neibu Shixuan San (Internal-Nourishing Ten-Accumulation Powder) and Naituo Huangqi Wan (Interior-Supporting Astragalus Pill).
My commentary: The Classics state: The Spleen governs the muscles. When the Spleen is healthy, muscles regenerate naturally. However, when the pathological condition is intense, the aforementioned medicines should be used to eliminate toxins. When the toxins are nearly exhausted, Sijunzi Tang (Four Gentlemen Decoction) should be used to nourish the Spleen (see Appendix on Key Medication Principles).
Naituo Huangqi Wan (Interior-Supporting Astragalus Pill) treats injuries caused by acupuncture and cupping/scarification, characterized by aversion to cold and fever, continuous discharge of pus, failure of muscle regeneration, and non-healing wounds.
Huangqi (Astragali Radix) 8 liang
Danggui (Angelicae Sinensis Radix) 3 liang (washed and dried)
Rougui (Cinnamomi Cortex) (outer bark removed)
Muxiang (Aucklandiae Radix)
Chenxiang (Aquilariae Lignum Resinatum)
Ruxiang (Boswelliae Resina) (separately ground) 1 liang each
Lvdou Mo (Vigna Radiata Semen Pulvis) 4 liang
Grind all into powder. Make pills using ginger juice and a paste made from mung bean flour. Swallow with well-cooked water.
My commentary: For the aforementioned conditions, if muscles are injured and the wound fails to heal, use Liujunzi Tang (Six Gentlemen Decoction) to tonify the spleen and stomach. If qi deficiency causes aversion to cold and the wound fails to heal, use Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction) to tonify the spleen and lungs. If blood deficiency causes fever and the wound fails to heal, use Siwu Tang (Four Substances Decoction) plus Renshen (Ginseng Radix) and Baizhu (Atractylodis Macrocephalae Rhizoma) to nourish the liver and spleen. If there is excessive pus and the wound fails to heal, use Bazhen Tang (Eight Treasures Decoction) or Shiquan Dabu Tang (Ten Complete Great Tonifying Decoction) to nourish blood and qi. The Classics state: The Spleen governs the muscles. If the aforementioned medicines are ineffective, simply use Sijunzi Tang, Danggui (Angelicae Sinensis Radix), and Shudi (Rehmanniae Radix Preparata) to tonify the spleen and stomach. If still ineffective, it belongs to decline of Mingmen Fire (Gate of Life Fire); urgently use Bawei Wan (Eight-Ingredient Pill) to strengthen fire to generate earth. If the pulse is rapid and accompanied by thirst, it is difficult to treat, as true qi is deficient and pathogenic factors are excess.
