【方歌】流注原有证数般，湿痰瘀风汗后寒，发无定处连肿漫，
溃近骨节治难痊，此证本由脾胃弱，留结肌肉骨筋间。
【注】此证名虽无殊，其原各异。盖人之血气，每日周身流行
，自无停息，或因湿痰，或因瘀血，或因风湿，或因伤
寒汗后余毒，或因欲后受寒，积留于肌肉之中，致令气
血不行，故名流注。
诸家书云：流者流行，注者住也，发无定处，随在可生
。初发漫肿无头，皮色不变，凝结日久，微热渐痛，透
红一点，方是脓熟，即宜用针开破。若湿痰化成者，脓
色粘白；瘀血化成者，脓色金黄；粘水风湿化成者，脓
色稀白如豆汁；汗后余邪化成者，脓色或黄、或黑，稀
脓秽臭；以上四证，发在肉厚处可愈，发在骨节及骨空
处难痊。淫欲受寒化成者，脓色稀白而腥，其水中有猪
脂水油之状，此为败浆脓也。诸书虽有治法，终成败证
。初起湿痰所中者，火香流气饮导之；产后瘀血所中者
，通经导滞汤通活之；跌扑伤损瘀血所中者，宜散瘀葛
根汤逐之；风湿所中者，万灵丹、五积散加附子温散之
；汗后余邪发肿者，人参败毒散散之；房欲后外寒侵袭
者，初宜服五积散加附子，次服附子八物汤温之；又有
室女、孀妇，郁怒伤肝，思虑伤脾而成者，宜服归脾汤
加香附青皮散之。此皆流注初起将成之法，一服至三、
四服皆可。外俱用乌龙膏或冲和膏敷贴，皮肉不热者，
雷火神针针之，轻者即消，重者其势必溃；将溃时俱宜
服托里透脓汤；已溃俱服人参养荣汤；久溃脓水清稀，
饮食减少，不能生肌收敛者，俱宜服调中大成汤；久溃
脓水清稀，精神怯少，渐成漏证者，俱宜服先天大造丸
。溃后其余治法，俱按痈疽溃疡门参考。

【方歌】流注病原本有多种证型，包括湿痰、瘀血、风湿以及伤寒发汗后遗留的寒邪。其特点是发病部位不固定，肿胀蔓延连片，溃破后若靠近骨节则难以治愈。此证的根源在于脾胃虚弱，导致病邪滞留结聚在肌肉与筋骨之间。
【注】此病名称虽无差异，但其病因各不相同。人的气血每天在全身循环流动，没有片刻停息。如果因为湿痰、瘀血、风湿，或者因伤寒发汗后余毒未清，又或因房事后受寒，这些邪气积聚停留在肌肉之中，致使气血运行不畅，因此称为“流注”。
各家医书说：“流”指流行，“注”指停留，发病部位不固定，随处都可能发生。初起时表现为漫肿无头，皮肤颜色不变；凝结日久后，出现微热并逐渐疼痛，直到透出一点红色，才表示脓液已成熟，此时应立即用针切开排脓。如果是湿痰化成的脓，颜色粘腻发白；瘀血化成的脓，颜色金黄；由水湿、风湿化成的脓，颜色稀薄发白如豆汁；由汗后余邪化成的脓，颜色或黄或黑，脓液稀薄且气味秽臭。以上四种证型，发生在肉厚处可以痊愈，发生在骨节及骨空处则难治。因淫欲过度受寒化成的脓，颜色稀白且有腥味，水中漂浮着类似猪脂油状物，这被称为败浆脓。虽然各书有治疗方法，但最终多转为坏证（难治之证）。
初起由湿痰引起的，用火香流气饮疏导；产后由瘀血引起的，用通经导滞汤疏通活血；跌打损伤致瘀血引起的，宜用散瘀葛根汤逐瘀；由风湿引起的，用万灵丹、五积散加附子温散；发汗后余邪致肿的，用人参败毒散发散；房事后感外寒侵袭的，初起宜服五积散加附子，随后服附子八物汤温补；又有少女、寡妇，因郁怒伤肝、思虑伤脾而形成的，宜服归脾汤加香附、青皮疏解。这些都是流注初起将成时的治法，服用一至四剂即可。外用均敷贴乌龙膏或冲和膏，若皮肉不热者，用雷火神针艾灸，轻症即消，重症必然溃破；将溃时均宜服托里透脓汤；已溃破均服人参养荣汤；久溃后脓水清稀，饮食减少，不能生肌收敛的，均宜服调中大成汤；久溃后脓水清稀，精神怯弱，渐成漏证的，均宜服先天大造丸。溃后的其他治法，均参照痈疽溃疡门的内容。

[Verse] Liu Zhu (Flowing Abscess) originally presents in several patterns, including damp-phlegm, blood stasis, wind-dampness, and residual cold after sweating from Taiyang disease. Its characteristics are an indeterminate location of onset with spreading swelling; if it ulcerates near bone joints, it is difficult to cure. This condition stems from Spleen-Stomach deficiency, causing pathogens to accumulate and knot between muscles, bones, and tendons.
[Annotation] Although the name of this condition is uniform, its origins vary. Human Qi and Blood circulate throughout the body daily without pause. If due to damp-phlegm, blood stasis, wind-dampness, or residual toxins after sweating from Cold Damage, or due to cold invasion after sexual intercourse, these pathogens accumulate in the muscles, obstructing the flow of Qi and Blood, hence named "Liu Zhu" (Flowing Abscess).
Various medical texts state: "Liu" means flowing, "Zhu" means stopping. The onset has no fixed location and can occur anywhere. Initially, it presents as a diffuse swelling without a head, with unchanged skin color. After long-term accumulation, slight heat and gradual pain appear. Only when a red spot emerges does it indicate that pus is ripe, at which point it should be incised with a needle immediately. If formed from damp-phlegm, the pus is sticky and white; if from blood stasis, the pus is golden yellow; if from water-dampness and wind-dampness, the pus is thin and white like bean juice; if from residual pathogens after sweating, the pus is either yellow or black, thin, and foul-smelling. Among these four types, those occurring in thick flesh areas can heal, while those at bone joints or hollows are difficult to cure. Pus formed from cold invasion after excessive sexual desire is thin, white, and fishy, containing oil-like substances resembling lard; this is called "Bai Jiang Nong" (Decayed Pus). Although various books offer treatments, they often result in refractory cases.
For initial damp-phlegm obstruction, use Huo Xiang Liu Qi Yin (Aromatic Qi-Regulating Decoction) to guide it out; for postpartum blood stasis, use Tong Jing Dao Zhi Tang (Unblocking Meridians and Guiding Stasis Decoction) to promote circulation; for trauma-induced blood stasis, use San Yu Ge Gen Tang (Dispersing Stasis and Kudzu Root Decoction) to expel it; for wind-dampness, use Wan Ling Dan (Ten Thousand Spirits Pill) and Wu Ji San (Five Accumulations Powder) with Fu Zi (Prepared Aconite Root) to warm and disperse; for swelling from residual pathogens after sweating, use Ren Shen Bai Du San (Ginseng Detoxification Powder) to scatter it; for external cold invasion after intercourse, initially take Wu Ji San with Fu Zi, followed by Fu Zi Ba Wu Tang (Aconite Eight-Ingredient Decoction) to warm; for young unmarried women or widows suffering from Liver injury due to anger and Spleen injury due overthinking, use Gui Pi Tang (Restore the Spleen Decoction) with Xiang Fu (Cyperus Rhizome) and Qing Pi (Tangerine Peel) to dissipate stagnation. These are methods for the initial stage of Liu Zhu. One to four doses are sufficient. Externally, apply Wu Long Gao (Black Dragon Ointment) or Chong He Gao (Harmonizing Ointment). If the skin and flesh are not hot, use Lei Huo Shen Zhen (Thunder-Fire Divine Needle/Moxibustion); mild cases resolve, severe cases will inevitably ulcerate. When about to ulcerate, take Tuo Li Tou Nong Tang (Supporting Interior and Penetrating Pus Decoction); after ulceration, take Ren Shen Yang Rong Tang (Ginseng Nourishing Nutritive Decoction); for chronic ulcers with thin pus, reduced appetite, and failure to regenerate tissue, take Diao Zhong Da Cheng Tang (Regulating Middle and Great Success Decoction); for chronic ulcers with thin pus, weak spirit, and progression to fistula, take Xian Tian Da Zao Wan (Heavenly Creation Pill). Other post-ulceration treatments refer to the Ulcerative Sores section.
