凡点灸时，若值阴雾大起，风雪忽降，猛雨炎暑，雷电虹 ，灸临时且停，候待晴明即
再下火灸。灸时不得伤饱大饥，饮酒大醉，食生硬物，兼忌思虑愁忧，恚怒呼骂，吁嗟叹息，
一切不祥，忌之大吉。
凡灸头四肢，皆不令多灸，缘人身有三百六十五络，皆归于头。头者，诸阳之会也。若
灸多令人头旋目眩，远视不明。缘头与四肢肌肉薄，若并灸则气血滞绝于炷下，宜歇火气少
时，令气血遂通，再使火气流行。候炷数足，自然除病，宜详察之。
凡灸发际，如是患人有发际整齐，根据明堂所说易取其穴。如是患人先因疾患后脱落尽
发际，或性本额项无发，难凭取穴。今定患人两眉中心直上三寸为发际，以此为准。
凡着灸疗病，历春夏秋冬不较者，灸炷虽然数足，得疮发脓坏，所患即瘥。如不得疮发
脓坏，其疾不愈。《甲乙经》云∶灸疮不发者，用故履底灸令热，熨之三日即发，脓出自然愈
疾。今用赤皮葱三五茎，去其葱青，于 灰火中煨熟，拍破，热熨灸疮十余遍，其疮三日
自发，立坏脓出疾愈。
凡着灸治病，才住火便用赤皮葱、薄荷二味煎汤，温温淋洗灸疮周回约一二尺，以来驱
令逐风气于疮口内出，兼令经脉往来不滞于疮下，自然疮坏疾愈。若灸疮退火痂后，用桃
树东南梢枝、青嫩柳枝皮二味等分煎汤，温温淋洗灸疮，此二味偏能护灸疮中诸风。若疮内
黑烂溃者，加胡荽三味等分煎汤，温温淋洗，灸疮自然生好肉也。若灸疮疼痛不可忍，多时
不较者，加黄连四味等分煎汤淋洗，立有神势。
在施灸时，如果遇到大雾弥漫、风雪突然降临、暴雨或酷暑炎热、雷电交加等恶劣天气，应暂时停止施灸，等待天气晴朗后再进行。施灸期间，患者不得处于过饱或极度饥饿状态，不得饮酒至大醉，不得食用生冷坚硬的食物，同时需避免思虑忧愁、愤怒呼骂、叹息等一切不祥的情绪和行为，严格遵守这些禁忌则大吉大利。
凡是灸治头部和四肢，都不宜多灸，因为人身有三百六十五络脉，都汇聚于头部。头是诸阳经交会的地方。如果灸治过多，会导致头晕目眩、视物模糊。因为头部和四肢的肌肉较薄，如果同时大量施灸，会导致穴位下的气血阻滞甚至断绝，因此应当暂停施灸片刻，让气血得以通畅，然后再继续施灸。待艾炷数量足够后，疾病自然痊愈，应当仔细审察这一点。
凡是灸治发际部位，如果患者的发际线整齐，可以根据《明堂》（针灸穴位图谱）所述容易取穴。如果患者因疾病导致发际完全脱落，或者天生额头和后颈无发，就难以凭借发际来取穴。现在规定以患者两眉中心直上三寸处作为发际线，以此为准绳。
凡是使用直接灸法治疗疾病，无论经历春夏秋冬哪个季节，只要艾炷数量足够，使灸疮发出脓液并溃破，所患疾病即可痊愈。如果不能形成灸疮、不出脓溃破，疾病就不会痊愈。《甲乙经》记载：灸疮不发者，可用旧鞋底加热熨烫，连续三天即可引发灸疮，脓液流出后疾病自然痊愈。现在采用赤皮葱三五根，去掉葱青部分，在灰火中煨熟，拍破后用热葱熨烫灸疮十余遍，灸疮三天内自然会发作，脓液流出，疾病迅速痊愈。
凡是使用直接灸法治病，刚停火后立即用赤皮葱和薄荷两味药煎汤，温热地淋洗灸疮周围约一二尺范围，以此来驱赶风气从疮口排出，同时使经脉气血在疮下运行通畅，自然疮坏病愈。如果灸疮退去火痂后，用桃树东南方向的嫩枝和青嫩柳树枝皮两味等量煎汤，温热地淋洗灸疮，这两味药特别能保护灸疮免受风邪侵袭。如果疮口内部黑烂溃破，加入胡荽（香菜），三味药等量煎汤，温热地淋洗，灸疮自然会生长出好肉。如果灸疮疼痛难忍，长时间不缓解，加入黄连，四味药等量煎汤淋洗，立刻会有显著疗效。
When applying moxibustion, if there is heavy fog, sudden snow or wind, torrential rain, intense heat, thunderstorms, or rainbows, temporarily suspend the procedure and wait for clear weather before resuming. During moxibustion, one must not be overly full or extremely hungry, must not drink to intoxication, must not consume raw or hard foods, and should avoid excessive thinking, sorrow, anger, cursing, sighing, and all other inauspicious behaviors; strictly observing these taboos brings great auspiciousness.
When treating the head and limbs with moxibustion, one should not apply excessive amounts of moxa, because the human body has 365 collaterals (Luo vessels), all of which converge at the head. The head is the meeting point of all Yang meridians. Excessive moxibustion on the head can cause dizziness, vertigo, and blurred vision. Since the muscles of the head and limbs are thin, simultaneous heavy moxibustion may cause stagnation or interruption of Qi and Blood under the moxa cone. Therefore, one should pause briefly to allow Qi and Blood to flow freely again before continuing. Once the prescribed number of cones has been applied, the disease will naturally resolve; this requires careful observation.
When treating the hairline, if the patient has a neat hairline, acupoints can be easily located according to the descriptions in *Mingtang* (Illustrated Manual of Acupuncture Points). If the patient has lost their hairline due to illness or was born without hair on the forehead and nape, locating points based on the hairline is difficult. It is now stipulated that the hairline is defined as three cun directly above the midpoint between the two eyebrows, using this as the standard.
When using direct moxibustion to treat diseases, regardless of the season, if the correct number of cones is applied and the moxa sore develops pus and ulcerates, the disease will heal. If the moxa sore does not develop or discharge pus, the disease will not resolve. The *Jia Yi Jing* states: For moxa sores that do not develop, heat an old shoe sole and apply it as a hot compress for three days to induce suppuration; once pus flows, the disease heals naturally. Currently, use three to five stalks of red-skin scallions, remove the green tops, roast them in ash until warm, crush them, and apply the warm scallion to the moxa sore for about ten repetitions. The sore will naturally develop within three days, discharging pus and curing the disease quickly.
After stopping the fire during direct moxibustion treatment, immediately decoct red-skin scallions and Bohe (Menthae Haplocalycis Herba) in water. Warmly wash the area surrounding the moxa sore (approximately one to two chi) to drive out pathogenic Wind from the wound and ensure unobstructed circulation of meridians below the sore, leading to natural healing. After the scab falls off, decoct equal parts of branches from the southeast tip of a peach tree and the bark of young willow twigs. Warmly wash the sore with this decoction; these two herbs specifically protect the sore from Wind pathogens. If the sore is black, rotten, and ulcerated, add Hu Su (Coriandri Fructus) to make three ingredients; decoct and wash warmly to promote healthy granulation tissue growth. If the pain from the moxa sore is unbearable and persists, add Huang Lian (Coptidis Rhizoma) to make four ingredients; decoct and wash with this mixture for immediate and significant therapeutic effects.
