可灸。必阳虚气弱者，始可用灸。今喻氏复辨阳虚者，固宜用灸。若阳虚至于外越者，岂容再灸？

辣蓼草八两，捣烂；木瓜四两，老酒二斤，加水煎煮，趁热揩擦熨烫患处及手足、遍身。辣蓼草是水的另一种别称植物，叶片狭小且光滑，两面皆绿，茎微红且有节，味道非常辛辣。它常与六神曲及酿酒曲一起使用。鸡若生了虱子，只需将此草放在鸡窝内即可痊愈。
将盐卤加热后淋洗，并用手蘸取摩擦患处（如果没有盐卤，可用极咸的盐水代替）。案语：这样永无足疾。
如果在路途上患病倒地者，只需将患者的双脚浸泡在溺桶中，效果也很好。绵絮浸在酒中，煮沸。取出后，趁热包裹患处。或者用烧酒摩擦患处，以皮肤松软为度，烧酒中加入斑蝥粉末，效力更强。
炒盐一包，熨烫其心腹部，使热气透入，再用一包熨烫背部，待手足变暖。再服用神香散一钱。寒重者，再服用（方剂见第四篇）。或者用吴茱萸、食盐各数两炒热，包好熨烫脐下也妙。或者用芥子、胡椒七粒，用布包好，嚼碎，纳入脐中，用膏药封住，再用热手按压。盖上被子躺一会儿，腹中发热，在上面盖蒜片，艾灸十四壮。病情危重的，再灸脐两旁各开二寸的天枢穴两穴，脐上四寸的中脘穴一穴，脐下一寸半的气海穴一穴。
《外台秘要》的方法：用手握住患脚的大拇趾，在脚心急筋处，灸七壮。
喻氏的方法：凡是突然遭受阴寒侵袭，四肢厥逆，呕吐腹泻，面色清冷，身体凛冽无汗的。用一大把葱，用带子束紧，切去两头，保留白色部分约一寸。将一面熨热后安放在脐上；用熨斗盛炭火，熨烫葱上面。使热气从脐进入腹部。严重的，连续熨烫二三张饼。更严重的，再用艾炷灸关元、气海穴各二三十壮。如果腠理素来疏松，阴盛逼阳而多汗的，可以用附子，可以灸。必须是阳虚气弱的，才可以使用灸法。现在喻氏又辨析说阳虚的人固然适宜用灸。但如果阳虚到了阳气外越的程度，岂能再灸？这也是提出前人未发之论，可以补充张仲景未涉及之处。世间那些不辨别阴阳，而胡乱施以灼灸伤害人的，难道只是霍乱如此吗？唉，令人叹息！又案语：凡是腹部虽然疼痛剧烈，但喜欢温暖，按压时嘴唇口角刮出白屑的，这是内虚阴寒的病。适宜用火灸，切忌针刺。如果四肢虽然寒冷但苦于口渴舌苔腻，腹痛虽然严重但眼睛红嘴唇红，或者烦躁喜欢凉的，这是热郁气闭的证候。急宜刺血，切忌火攻。如果不辨明而误用，祸患就在反掌之间。
Raw garlic, pounded into a paste, applied to the soles of both feet.
One liang of Evodiae Fructus (Wuzhuyu), ground into powder, mixed with brine, and applied to the soles of both feet.
Eight liang of Polygoni Multiflori Caulis (Liaoliao Cao), pounded into a paste; four liang of Chaenomelis Fructus (Mugua); two jin of aged wine; add water and decoct. While hot, rub and moxa-iron the affected area and all over the hands, feet, and body. Liaoliao Cao is another name for a type of water plant; its leaves are narrow and smooth, green on both sides, with slightly reddish, jointed stems, and a very pungent taste. It is used together with Shenqu (Massa Medicata Fermentata) and yeast in brewing. If chickens have lice, placing this grass in their roost will cure them.
Heat the brine and wash the affected area by pouring it over, and use your hand to dip and rub the area (if brine is unavailable, extremely salty water can be used as a substitute). Note: This prevents foot diseases forever.
If one collapses from illness while traveling, simply immersing the patient's feet in a night soil bucket is also effective. Soak cotton wadding in wine, boil until rolling. Remove and wrap the affected area while hot. Alternatively, rub the affected area with distilled liquor until the skin becomes soft. Adding Mylabris Powder (Banmao) to the distilled liquor enhances its efficacy.
If the feet are not cold, simply grind salt finely and rub it on the area.
Decoct blue cloth in water and apply compresses to the feet and knees; replace when cool.
Pound Perilla Folium (Baiye) into a paste and wrap the area; also decoct for washing.
Mainly treats Huoluan (Cholera-like disease) with muscle cramps, specifically Cold-type Gan Huoluan (Dry Cholera).
One bag of fried salt, iron the epigastrium and abdomen until heat penetrates, then use another bag to iron the back until the hands and feet become warm. Then administer one qian of Shenxiang San (Divine Fragrance Powder). For severe cold, administer again (formula see in Chapter 4). Or, stir-fry several liang of Evodiae Fructus (Wuzhuyu) and edible salt until hot, wrap, and iron below the umbilicus, which is also effective. Or, take seven grains of Mustard Seed (Jiezi) and Pepper (Hujiao), wrap in cloth, chew thoroughly, place in the umbilicus, seal with a plaster, and press with warm hands. Cover with a quilt and lie down for a short while until warmth arises in the abdomen. Place slices of garlic above and perform moxibustion for fourteen burns (two sevens). In critical cases, additionally moxa-ox the Tianshu (ST25) acupoints, located two cun lateral to the umbilicus on both sides, the Zhongwan (CV12) acupoint, located four cun above the umbilicus, and the Qihai (CV6) acupoint, located one and a half cun below the umbilicus.
Method from *Waitai Miyao*: Hold the big toe of the affected foot, locate the urgent tendon at the center of the sole, and moxa-ox seven burns.
Method from Master Yu: For sudden onset of Yin-Cold, with cold limbs, vomiting and diarrhea, clear complexion, cold body, and absence of sweat. Take a large handful of Scallion Stem (Congbai), bind tightly with a strap, cut off both ends, leaving about one cun of the white part. Iron one side until hot, place on the umbilicus; use an ironing pot filled with charcoal fire to iron the top of the scallion. Allow the heat to enter the abdomen through the umbilicus. For severe cases, continue ironing two or three cakes. For even more severe cases, additionally moxa-ox the Guanyuan (CV4) and Qihai (CV6) acupoints with twenty to thirty burns each. If the pores are naturally loose, and Yin excess forces Yang outward causing excessive sweating, Aconite Radix Preparata (Fuzi) can be used; moxibustion is permissible. Moxibustion should only be used for those with true Yang deficiency and Qi weakness. Now, Master Yu further clarifies that while those with Yang deficiency indeed benefit from moxibustion, what if Yang deficiency has progressed to Yang floating outward? How can moxibustion still be applied? This insight reveals what was previously unspoken and supplements the omissions of Zhang Zhongjing. Alas, how lamentable that people in the world fail to distinguish Yin and Yang, recklessly applying burning moxibustion and harming others! Is this phenomenon limited only to Huoluan? Another note: Whenever abdominal pain is extreme but relieved by warmth, and scraping the lips and mouth yields white residue, this is a disease of internal deficiency and Yin-Cold. Fire moxibustion is appropriate; needle puncture is strictly contraindicated. If the limbs are cold but accompanied by bitter thirst and greasy tongue coating, or if abdominal pain is severe but eyes are red, lips are red, or there is irritability and preference for coolness, this is a syndrome of Heat stagnation and Qi closure. Bloodletting is urgently indicated; fire therapy is strictly contraindicated. Failure to distinguish clearly and using the wrong method will bring disaster instantly.
