李梴在《医学入门》中记载：凡是施灸，必须使灸处发泡化脓（即“发疮”），所患疾病才能痊愈。如果灸后不发疮，疾病就不会治愈。《甲乙经》中说：灸后疮口不发的，可以用鞋底烧炙令其发热，熨烫患处，三天后疮就会发出。现在的人用赤皮葱三五根，去掉青皮，在灰火中煨热拍破，趁热熨烫疮口十余遍，疮口三个月后便会发出；也可以用生麻油浸泡患处使其发出；也有用皂角煎汤，待冷却后频频点涂的。此外，也有人担心气血衰弱导致不发，而服用四物汤来滋养气血，这种情况不能一概而论。有的再灸一两壮就能发出，有的食用热性炙烤食物如烤鱼、煎豆腐、羊肉等也能促使发疮。这需要根据情况灵活辅助，不可听之任意。
王肯堂在《证治准绳》中记载：灸后不可以立即饮茶，恐怕会解掉艾火的火力；进食也恐阻碍经气运行。应当停歇一两个时辰，必须在安静室内卧床休息，平心定气，戒除色欲、劳累和愤怒。饮食方面忌食生冷瓜果，只宜吃清淡养胃的食物，使气血流通，让艾火驱逐病气排出体外。如果食用浓味醇酒，会导致生痰涎，阻滞病气。鲜鱼、鸡肉、羊肉虽然能助火，但只适用于初灸旬日之内，不可在半月之后加用。如今的人不懂得恬淡修养，即使施灸又有什么益处？因此因施灸反而致害的情况是存在的。
古人施灸时艾炷较大，便使用清洗方法。用赤皮葱和薄荷煎汤，温洗疮口周围，约一小时左右，以驱赶风邪从疮口排出，更令经脉往来通畅不涩滞，疾病自然痊愈。如果是灸火退去痂皮后，用东南方向的桃枝青嫩皮煎汤温洗，能保护疮中免受诸风侵袭。如果疮口黑烂，加胡荽煎汤清洗；如果疼痛难忍，加黄连煎汤，神效。○如果本不该灸而误灸，导致灸疮疼痛难忍，以致肌肉飞散成片，名叫“飞蝶”，宜用大黄、芒硝煎浓汁，频频清洗灸处。疼痛仍不止，可将此药喝一二杯，疼痛即可消除。
Li Chan recorded in *Yixue Rumen* (Introduction to Medicine): Whenever moxibustion is applied, it is essential for the site to blister and suppurate (fa chuang), so that the disease may be cured. If no blister forms, the disease will not heal. The *Jia Yi Jing* states: For moxa blisters that do not develop, one may roast a shoe sole until hot and apply it as a warm compress to the affected area; the blister will appear within three days. Currently, people use three or five stalks of red-skin scallions, removing the green parts, warming them in ash, crushing them, and applying the heat to the moxa site for more than ten times, causing the blister to emerge after three months. Alternatively, soaking the site with raw sesame oil can induce blistering. Some also use decoctions of Gleditsiae Fructus (Zaojiao, 皂角) cooled and frequently applied. Furthermore, some fear that declining Qi and Blood prevent blistering and administer Siwu Tang (Four Substances Decoction) to nourish Qi and Blood; such cases cannot be generalized. In some instances, adding one or two moxa cones induces blistering; in others, consuming hot roasted foods like grilled fish, fried tofu, or mutton promotes it. One must flexibly assist according to circumstances, rather than leaving things to chance.
Wang Kentang recorded in *Zhengzhi Zhunsheng* (Standardized Treatments for Diagnoses): After moxibustion, one should not drink tea immediately, lest it dissipate the fire energy of the moxa; eating may also obstruct the flow of Jing Qi (Meridian Qi). It is advisable to wait one or two shichen (two to four hours), rest in a quiet room, calm the mind and regulate the breath, and abstain from sexual desire, overexertion, and anger. Diet should avoid raw, cold fruits and vegetables; only light and bland foods that nourish the Stomach should be consumed, ensuring the smooth flow of Qi and Blood so that the moxa fire expels pathogenic factors. Consuming rich flavors and strong wine generates Phlegm-Fluids, which block the expulsion of pathogens. While fresh fish, chicken, and mutton can stimulate fire, they are applicable only within the first ten days of initial moxibustion and should not be added after half a month. Today’s people fail to practice tranquil cultivation; thus, even if they undergo moxibustion, what benefit is there? Consequently, harm resulting from moxibustion does occur.
In ancient times, when large moxa cones were used, a washing method was employed. A decoction of red-skin scallions and Menthae Haplocalycis Herba (Bohe, 薄荷) was used to wash around the wound while warm for about an hour, driving Wind pathogens out through the wound opening, thereby ensuring unobstructed circulation in the meridians and natural recovery. After the moxa burn scabs fall off, washing with a decoction of the tender green bark of peach branches from the southeast protects the wound from various Wind pathogens. If the wound becomes black and ulcerated, add Coriandri Fructus (Husui, 胡荽) to the decoction for washing. If pain is unbearable, add Coptidis Rhizoma (Huanglian, 黄连) to the decoction for miraculous effect. ○ If moxibustion is mistakenly applied where it is contraindicated, causing unbearable pain and tissue necrosis resembling flying butterflies (Feidie, 飞蝶), a concentrated decoction of Rhei Radix et Rhizoma (Dahuang, 大黄) and Natrii Sulfas (Mangxiao, 芒硝) should be used to frequently wash the moxa site. If pain persists, drinking one or two cups of this medicine will eliminate it.
