古人谓少阴、厥阴、阴毒三证则宜灸，或用葱熨等法，皆为身表凉故也。若阴气在内，
阳气
在外，身表壮热，手足大温或热不等，则不宜灸之。若遇前三证，用热醋炒麸注布袋中，脐
下熏蒸熨极妙。又云∶三阴证陷骨、歧骨间，三五七壮灸，足温生。
《活人》阴证，诸药不效，并汤水不下，身冷脉绝，气息短，不知人，用葱熨法。本为上热
下寒
也，二法虽妙。莫若用上醋拌麸炒热，注布袋中，脐下熏蒸，比上二法尤速。若更以葱白煎
浆作汤，以沐四肢亦可。若病患服药后，欲作汗时，用汤沐以接四肢阳气尤佳。
外接法
干姜二，炮为细末，石决明一，另研细，称拌匀，每服二三钱匕，手心中以津唾调如泥
，以手奄其阴，至暖汗出为度。以牡蛎代决明亦可，牡蛎烧粉用。
一法∶丁香、荜茇、干姜、牡蛎。
一法∶治水 偏大，上下不定，疼痛不止，牡蛎不以少多，盐泥固济，炭三斤， 令火尽
，冷取二两，干姜一两，炮为细末，二味和匀，冷水调得所，涂病处，小便大利即愈。
神阙一穴，脐中，禁针，刺之令人出恶汁不止。
阴交一穴，脐下一寸。
气海一穴，一名孛央，阴交下五分。
石门一穴，脐下二寸，三焦之募，女子禁灸，恐绝产也。
关元一穴，脐下三寸，小肠之募，为下纪三阴，任脉会。
中极一穴，脐下四寸，为气原。
古人认为少阴病、厥阴病、阴毒这三类证候适宜采用艾灸治疗，或者使用葱熨等方法，这都是因为患者体表发凉的原因。如果阴气郁结在体内，阳气浮越于体表，导致身体表面高热，手足温暖甚至发热程度不一，则不适宜进行艾灸。如果遇到上述前三类证候，可以用热醋拌炒麦麸装入布袋中，对脐下部位进行熏蒸熨烫，效果极佳。又有说法称：对于三阴证陷入骨缝的情况，在歧骨间（胸剑联合与脐连线处）施灸三五七壮，待足部回暖即可见效。
《活人书》中记载的阴证，若各种药物无效，且汤水无法咽下，身体冰冷、脉搏消失、气息微弱、神志昏迷，可使用葱熨法。这原本是针对上热下寒的病机，虽然这两种方法都很巧妙，但不如用老醋拌炒麦麸至热，装入布袋中对脐下进行熏蒸，速度比前两种方法更快。如果再配合用葱白煎煮浆水作为药汤来沐浴四肢，也是可以的。如果患者在服药后想要出汗时，用药汤沐浴以接续四肢的阳气，尤为适宜。
外接法（外用接阳法）：干姜二份，炮制后研成细末；石决明一份，单独研细。称量均匀混合，每次服用二三钱匕，在手心中用唾液调成泥状，用手覆盖住患者的阴部，直到出现暖汗为止。也可以用牡蛎代替石决明，需将牡蛎烧制成粉使用。
另一种方法：治疗水肿偏盛，上下移动不定，疼痛不止，取适量牡蛎，用盐泥密封固济，用三斤炭火煅烧至火尽，冷却后取二两，配干姜一两，炮制后研成细末，两味药混合均匀，用冷水调匀，涂抹于患处，小便通利顺畅即痊愈。
神阙穴，位于脐中央，禁止针刺，针刺会导致恶汁流出不止。
阴交穴，位于脐下一寸。
气海穴，又名孛央，位于阴交穴下方五分处。
石门穴，位于脐下二寸，是三焦的募穴，女子禁止艾灸，恐怕会导致绝育。
关元穴，位于脐下三寸，是小肠的募穴，为下纪及三阴经交会之处，任脉会合于此。
中极穴，位于脐下四寸，为气的本源所在。
The ancients stated that Shaoyin disease (Disease of the Lesser Yin), Jueyin disease (Disease of the Extreme Yin), and Yindu syndrome (Yin Toxin) are suitable for moxibustion, or methods such as scallion ironing, primarily because the body surface is cool. If Yin qi is stagnant internally while Yang qi floats externally, resulting in high fever on the body surface and hands/feet being warm or hot to varying degrees, moxibustion is contraindicated. In cases involving the aforementioned three syndromes, it is excellent to stir-fry wheat bran with hot vinegar, place it in a cloth bag, and fumigate and iron the area below the umbilicus. It is also said that for San Yin syndromes sinking into the bone gaps, applying 3, 5, or 7 moxa cones between the Qigu (the junction of the xiphoid process and the umbilicus) will restore warmth to the feet once the treatment is complete.
The *Huo Ren* (Life-Saving Book) records that for Yin syndromes where various medicines fail, fluids cannot be swallowed, the body is cold, the pulse is imperceptible, breath is short, and consciousness is lost, the scallion ironing method should be used. This originally addresses the pathogenesis of upper heat and lower cold. Although both methods are ingenious, using old vinegar to stir-fry wheat bran until hot, placing it in a cloth bag, and fumigating below the umbilicus is faster than the previous two methods. Furthermore, bathing the four limbs with a decoction of scallion whites boiled in fermented grain juice is also beneficial. If a patient desires to sweat after taking medicine, bathing with this decoction to reconnect the Yang qi of the four limbs is particularly advantageous.
External Connection Method: Gan Jiang (Prepared Rhizoma Zingiberis), 2 parts, processed into fine powder; Shijue Ming (Concha Haliotidis), 1 part, ground separately into fine powder. Measure and mix evenly. Take 2-3 qianbi per dose, mix with saliva in the palm to form a paste, cover the patient's genitalia with the hand, until warm sweat appears. Mu Li (Concha Ostreae) can replace Shijue Ming; use calcined Mu Li powder.
Another method: Ding Xiang (Flos Caryophylli), Bi Bo (Fructus Piperis Longi), Gan Jiang (Prepared Rhizoma Zingiberis), Mu Li (Concha Ostreae).
Another method: For treating edema that is predominant, moving up and down不定ly, with unceasing pain, take an appropriate amount of Mu Li (Concha Ostreae), seal firmly with salt mud, roast over 3 jin of charcoal until the fire is exhausted, cool and take 2 liang. Mix with 1 liang of Gan Jiang (Prepared Rhizoma Zingiberis), processed into fine powder. Mix the two ingredients evenly, adjust with cold water to the proper consistency, apply to the affected area. Recovery occurs when urination becomes abundant and smooth.

Qihai (CV6), also known as Bei Yang, located 0.5 cun below Yinjiao.
Shimen (CV5), located 2 cun below the umbilicus, is the Front-Mu point of the San Jiao (Triple Burner). Moxibustion is contraindicated for women, as it may cause sterility.
Guanyuan (CV4), located 3 cun below the umbilicus, is the Front-Mu point of the Small Intestine, serving as the Lower Ji and the convergence of the Three Yin meridians and the Ren Mai (Conception Vessel).
