如肿疡初起，审症处分，必以一药为标使。如神授卫生散，用金银花、当归、苍术。
复煎散，用苍术。十全大补汤，用夏枯草。蜡矾丸，用菊花汤。通圣散用漏芦之类。每用
一两煎汤，复煎群药，其应如响，此飞霞子之秘廖也。丹溪云∶阿胶饮，牛胶丸，属金
属土，实大肠，壮胃止泻，黄蜡丸入大肠有补，国老膏化毒行经，远志酒，金银花酒，皆
有补性，归血归心，善用者以之配入，肿疡之散结，溃疡之补虚，亦奏捷效，宜触类而
长之可也。又如诸毒生于巅顶者，诸药俱宜
酒浸、酒炒、酒煎、酒服，为使为因，所为在上者，因而越之也。
书云∶汗之则疮已，为外有六经之形症，内无便溺之阻隔，饮食如故，两便自调，知
不在里也。左脉洪缓，关脉带弦，外感客邪也，故宜汗之，使荣卫通，邪气去矣。如冬
月寒致腠理，必用辛温之剂以托之，如托里温中汤，绀珠丹之类。又云∶助表不以取汗
为功，为蟾酥朱砂雄黄等解毒之类，乃取汗之峻剂也。又云∶疮家虽身疼痛，不可发汗，
汗之则痉，为无表症也。即有表症，然亦不可大汗，大汗则表虚不脓，后必难治。汗出
不利小便，汗止则阳气复，小便自利也。

如果疮疡初起，在辨证施治时，必须以一味药作为引导药（使药）。例如神授卫生散，使用金银花、当归、苍术；复煎散，使用苍术；十全大补汤，使用夏枯草；蜡矾丸，用菊花汤送服；通圣散使用漏芦等类药材。每味药取一两煎成汤剂，再用此汤来煎煮其他药物，疗效迅速显著，这是飞霞子的秘密疗法。丹溪说：阿胶饮、牛胶丸，属性属金土，能充实大肠，强壮脾胃，止住腹泻；黄蜡丸进入大肠有补益作用；国老膏（甘草制剂）能化解毒邪，通行经络；远志酒、金银花酒，都有补益性质，能使血液回归心脏，善于用药的人将其配伍使用，对于疮疡初起的消散结块和溃疡后期的补虚，也能取得快速疗效，应当触类旁通地加以运用。又如各种毒疮生于头顶部位，所有药物都适宜用酒浸泡、酒炒、酒煎或酒送服，以此作为引导药或因势利导，这是因为病位在上，应当采用涌吐或升提的方法（此处指借酒性上行）。
古籍记载：通过发汗可以使疮疡痊愈，这是因为体表有六经的症状表现，体内没有大小便的阻滞，饮食正常，二便调畅，知道病邪不在里。左脉洪大而缓，关脉带弦象，这是外感客邪所致，所以适宜发汗，使营卫通畅，邪气得以去除。如果是冬季寒邪导致腠理闭塞，必须使用辛温的药物来托举透发，如托里温中汤、绀珠丹之类。又说：辅助表证治疗不以发汗为功效，因为蟾酥、朱砂、雄黄等解毒类药物，属于发汗的峻猛药剂。又说：患疮疡的人即使身体疼痛，也不可发汗，发汗会导致痉挛，这是因为没有表证。即使有表证，也不可以大汗，大汗则导致表虚不能化脓，后来必定难以治疗。汗出后小便不利，汗止则阳气恢复，小便自然通利。

When a carbuncle or ulcer first appears, after examining the symptoms and determining the treatment, one drug must be used as the guiding agent (shi yao). For example, Shen Shou Wei Sheng San uses Jinyinhua (Lonicerae Japonicae Flos), Danggui (Angelicae Sinensis Radix), and Cangzhu (Atractylodis Rhizoma); Fu Jian San uses Cangzhu; Shiquan Dabu Tang uses Xiakucao; La Fan Wan is taken with Ju Hua Tang (Chrysanthemi Flos decoction); Tong Sheng San uses Loulu and similar herbs. Each of these guiding herbs is taken in an amount of one liang, decocted into soup, and then used to decoct the other group of medicines. The response is immediate and effective; this is the secret method of Fei Xia Zi. Dan Xi stated: E'jiao Yin and Niu Jiao Wan belong to Metal and Earth elements, solidify the Large Intestine, strengthen the Stomach, and stop diarrhea; Huang La Wan enters the Large Intestine with tonifying effects; Guo Lao Gao (Licorice preparation) resolves toxins and unblocks meridians; Yuan Zhi Jiu and Jinyinhua Jiu both have tonifying properties, returning blood to the Heart. Skilled practitioners use them in combinations. They achieve rapid results in dissipating nodules in early-stage ulcers and tonifying deficiency in late-stage ulcers. One should apply this principle by analogy. Furthermore, for various toxins arising on the vertex of the head, all medicines are suitable for wine soaking, wine frying, wine decocting, or wine administration as guiding agents or due to their nature, because "what is above should be raised" (referring to using wine's ascending property).
Ancient texts state: "Diaphoresis cures the sore," applicable when there are exterior manifestations of the Six Meridians, no internal obstruction of urination or defecation, normal diet, and regulated bowel movements, indicating the pathogen is not in the interior. If the left pulse is surging and slow, and the guan position pulse is wiry, it indicates external pathogenic invasion; thus, diaphoresis is appropriate to unblock Ying and Wei (Nutritive and Defensive Qi) and expel the pathogen. In winter, cold causes the pores to close; pungent-warm formulas such as Tuo Li Wen Zhong Tang and Gan Zhu Dan must be used to support and release. It is also said: Supporting the exterior does not aim at inducing sweat, as drugs like Chan Su (Toad Venom), Zhu Sha (Cinnabar), and Xiong Huang (Realgar) are detoxifying agents, which are harsh diaphoretic agents. It is further said: Patients with sores who experience body pain should not undergo diaphoresis; doing so leads to spasms because there is no exterior syndrome. Even if an exterior syndrome exists, profuse sweating should be avoided; excessive sweating causes exterior deficiency and prevents pus formation, making subsequent treatment difficult. After sweating, if urination is difficult, stopping the sweat allows Yang Qi to recover, and urination becomes normal.
