灸法温暖宜于午,上下阳阴先后分,脉数新愈不宜灸,欲灸三里过三旬。
【注】凡灸百病,原为温暖经络,宜在午时阳盛之时,火气易行,必发上下先后∶上
下经皆灸者,先灸上,后灸下;阴阳经皆灸者,先灸阳,后灸阴。若脉数有热,新愈气
虚,俱不宜灸,恐伤气血。但人有病,欲灸足三里者,须年三十以上,方许灸之,恐年
少火盛伤目。故凡灸头,必灸足三里者,以足三里能下火气也。
头骨手足皮薄瘦,巨阙鸠尾小少宜,背腹脐下皮肉浓,大多方能起痼疾。
【注】凡灸诸病,必火足气到,始能求愈。然头与四肢,皮肉浅薄,若并灸之,恐肌骨
气血难堪,必分日灸之,或隔日灸之。其炷宜小,壮数宜少。有病必当灸巨阙、鸠尾二
穴者,必不可过三壮,艾炷如小麦,恐火气伤心也。背腹下皮肉深浓,艾炷宜大,壮数
宜多,使火气到,始能去痼冷之疾也。
灸后风寒须谨避,七情过极慎起居,生冷醇酒诸浓味,惟茹蔬淡适其宜。
【注】凡灸后,须谨避风寒,慎其起居,养其气血,其喜、怒、忧、思、悲、恐、惊不可过极,
和其情志,及禁食一切生冷醇酒浓味等物,即食蔬淡,亦当适宜,不可过度,以调养脾胃也。
灸疮不发气血竭,七日发脓病必除,发
后膏贴防外袭,薄连葱荽净疮污。
【注】凡灸诸病,灸疮应发不发,是其气血大亏,不必复灸,即灸亦多不能愈。过七
天之后,艾疤发时,脓水稠多,其病易愈,以其气血充畅,经络流通也。发后贴膏药者,防
其六淫外袭也。如灸疮黑痛,脓汁污秽,乃艾火毒盛,必用薄荷、黄连、葱皮、芫荽煎
汤,洗之自愈也。
灸法性属温暖,适宜在午时进行,施灸顺序需根据经脉的上下和阴阳属性来区分。若脉象数疾或病后初愈者不宜施灸;若想灸足三里穴,须年满三十岁以上方可施行。
【注】凡是艾灸治疗各种疾病,原本是为了温暖经络,适宜在午时阳气旺盛的时候进行,此时火气容易运行。必须明确施灸的先后次序:如果上下部位的经脉都要灸,应先灸上部,后灸下部;如果阴阳经脉都要灸,应先灸阳经,后灸阴经。如果脉象数疾伴有发热,或者病后初愈、正气虚弱,都不适宜施灸,恐怕会损伤气血。但是人有疾病,想要灸足三里穴的,必须年满三十岁以上,才允许施灸,恐怕年轻人阳气旺盛,施灸会伤及眼睛。所以凡是灸头部,必须配合灸足三里穴,因为足三里穴能够引火下行。
头骨和手足部位皮肉浅薄消瘦,巨阙穴和鸠尾穴施灸宜小且量少为宜;背部、腹部和脐下部位皮肉深厚浓密,大多能治愈顽固性疾病。
【注】凡是艾灸各种疾病,必须火力充足、气至病所,才能求得痊愈。然而头部与四肢,皮肉浅薄,如果同时施灸,恐怕肌肉骨骼和气血难以承受,必须分日施灸,或者隔日施灸。艾炷应当小巧,壮数应当少。如果有病必须灸巨阙、鸠尾两个穴位的,绝对不能超过三壮,艾炷大小如小麦,恐怕火气会伤害心脏。背部、腹部下方皮肉深浓,艾炷应当大,壮数应当多,使火气到达深处,才能去除顽固寒冷的疾病。
施灸后要谨慎避开风寒,七情过极时要谨慎起居,生冷、醇酒及各种浓厚口味的食物,只吃蔬菜和清淡饮食才适宜。
【注】凡是施灸后,必须谨慎避开风寒,小心起居生活,调养气血,喜、怒、忧、思、悲、恐、惊这七种情绪不可过度,要调和情志,并且禁止食用一切生冷、醇酒、浓厚口味等食物,即使是吃蔬菜和清淡饮食,也应当适宜,不可过度,以此来调养脾胃。
灸疮如果不发出来,说明气血枯竭;七天发出脓液,疾病必定消除;发疮后贴膏药以防外邪侵袭,用薄荷、葱、芫荽洗净疮面污垢。
【注】凡是艾灸各种疾病,灸疮应该发出来却不发出来,是气血严重亏损,不必再灸,即使再灸也多不能痊愈。过了七天之后,艾疤发作时,脓水稠厚量多,疾病容易痊愈,这是因为气血充盛通畅,经络流通的缘故。发疮后贴膏药,是为了防止六淫(风、寒、暑、湿、燥、火)外邪侵袭。如果灸疮颜色黑痛,脓汁污秽,这是艾火毒气旺盛,必须用薄荷、黄连、葱皮、芫荽煎汤清洗,自然就会痊愈。
Moxibustion, being warm in nature, is suitable for the Wu hour (noon). The sequence of application should be distinguished according to the upper/lower and yin/yang meridians. Moxibustion is not suitable for those with a rapid pulse or those who have just recovered from illness. If one wishes to apply moxibustion to Zusanli (ST36), it must be performed only after the age of thirty.
[Note] Generally, moxibustion for various diseases aims to warm the meridians. It is best performed during the Wu hour when yang qi is abundant, facilitating the flow of fire qi. The sequence of application must be observed: if both upper and lower meridians are treated, treat the upper part first, then the lower; if both yin and yang meridians are treated, treat the yang meridians first, then the yin. If there is a rapid pulse with heat, or if the patient has recently recovered and suffers from qi deficiency, moxibustion is contraindicated as it may damage qi and blood. However, for patients requiring moxibustion on Zusanli (ST36), they must be over thirty years old to proceed, to avoid damaging the eyes due to excessive fire qi in youth. Therefore, whenever moxibustion is applied to the head, Zusanli (ST36) must also be treated, as Zusanli can guide fire qi downward.
The skull and extremities have thin and emaciated skin and flesh; for Jueque (CV14) and Jiutui (CV15), small amounts and few moxa cones are appropriate. The back, abdomen, and area below the navel have thick and dense skin and flesh, making them suitable for treating chronic diseases with larger applications.
[Note] For moxibustion on various diseases, sufficient fire power and arrival of qi at the disease site are required for recovery. However, since the skin and flesh of the head and four limbs are shallow and thin, simultaneous moxibustion may overwhelm the muscles, bones, qi, and blood. Therefore, it should be performed on separate days or every other day. The moxa cones should be small, and the number of moxibustions (zhuang) should be few. If moxibustion is necessary on Jueque (CV14) and Jiutui (CV15), it must not exceed three zhuang, with moxa cones the size of wheat grains, to prevent fire qi from damaging the heart. In contrast, the skin and flesh of the back and lower abdomen are deep and thick; larger moxa cones and more zhuang are appropriate to ensure fire qi penetrates deeply, thereby dispelling chronic cold conditions.
After moxibustion, one must carefully avoid wind and cold, regulate daily activities, and nourish qi and blood. One must guard against extremes in the seven emotions (joy, anger, worry, thought, sadness, fear, fright) to harmonize emotional states. Dietary restrictions include avoiding raw, cold, strong alcoholic beverages, and rich flavors. A diet of vegetables and light foods is appropriate, but moderation is key to nourishing the spleen and stomach.
If the moxibustion sore does not erupt, it indicates exhaustion of qi and blood; if pus develops after seven days, the disease will likely be cured. After eruption, apply plasters to prevent external pathogenic invasion, and use peppermint, scallion, and coriander to cleanse the wound.
[Note] When moxibustion sores fail to erupt despite treatment, it signifies severe depletion of qi and blood. Further moxibustion is unnecessary and unlikely to be effective. After seven days, if the moxa scar erupts with thick and abundant pus, the disease is prone to cure, indicating that qi and blood are abundant and meridians are unobstructed. Applying plasters after eruption prevents invasion by the six excesses (wind, cold, summer-heat, dampness, dryness, fire). If the moxibustion sore appears black and painful with foul-smelling pus, it indicates intense toxicity from the moxa fire. It must be washed with a decoction of Peppermint Herb (Bohe), Coptis Rhizome (Huanglian), Scallion Skin (Congpi), and Coriander Fruit (Yansui) to heal naturally.
