大法，冬宜服温热药及灸。
师曰∶病发热头痛，脉反沉。若不瘥，身体更疼痛，当救其里，宜温药，四逆汤。
下利，腹满，身体疼痛，先温其里，宜四逆汤。自利，不渴者，属太阴，其脏有寒故也。当温之，宜四逆辈。
少阴病，其人饮食入则吐，心中温温欲吐，复不能吐。始得之，手足寒，脉弦迟。若膈上有寒饮，干呕者，不可吐，
当温之，宜四逆汤。
少阴病，脉沉者，急当温之，宜四逆汤。
下利，欲食者，就当温之。
下利，脉迟紧，为痛未欲止，当温之。得冷者满，而便肠垢。
下利，其脉浮大，此为虚，以强下之故也。设脉浮革，因尔肠鸣，当温之，宜当归四逆汤。
少阴病，下利，脉微涩者，即呕汗出，必数更衣，反少，当温之。
伤寒，医下之，续得下利，清谷不止，身体疼痛，急当救里，宜温之，以四逆汤。
微数之脉，慎不可灸，因火为邪，则为烦逆，追虚逐实，血散脉中，火气虽微，内攻有力，焦骨伤筋，血难复也。
脉浮，当以汗解，而反灸之，邪无从去，因火而盛，病从腰以下，必当重而痹，此为火逆。若欲自解，当先烦，烦乃有
汗，随汗而解。何以知之？脉浮，故知汗出当解。脉浮，热甚，而灸之，此为实，实以虚治，因火而动，咽燥必唾血。
烧针令其汗，针处被寒，核起而赤者，必发贲豚。气从少腹上撞者，灸其核上一壮（一本作各一壮），与桂枝加桂汤。
少阴病，得之一、二日，口中和，其背恶寒者，当灸之。
少阴病，其人吐利，手足不逆，反发热，不死。脉不至者，灸其少阴七壮。
少阴病，下利，脉微涩者，即呕汗出，必数更衣，反少，当温其上，灸之（一云灸厥阴可五十壮）。诸下利，皆可灸
足大都五壮（一云七壮），商丘、阴陵泉皆三壮。
下利，手足厥，无脉，灸之不温，反微喘者，死。少阴负趺阳者，为顺也。
伤寒六、七日，其脉微，手足厥，烦躁，灸其厥阴，厥不还者，死。
伤寒，脉促，手足厥逆，可灸之，为可灸少阴，厥阴主逆。
General principles state that in winter, it is appropriate to administer warm-natured herbs and perform moxibustion.
The Master said: When a patient presents with fever and headache, but the pulse is surprisingly deep (Chen). If the condition does not improve and body pain intensifies, one should rescue the interior (Ji) first, using warm formulas such as Sini Tang (Four Reversal Decoction).
In cases of diarrhea (Xia Li), abdominal fullness, and body pain, one should first warm the interior, preferably with Sini Tang. Spontaneous diarrhea without thirst belongs to Taiyin disease, caused by cold in the zang organs. It should be treated with warming methods, suitable for Sini Tang-type formulas.
In Shaoyin disease, if the patient vomits immediately after eating, feels a warm sensation in the heart region with an urge to vomit but cannot, and initially presents with cold hands and feet and a wiry-chi (slow) pulse: if there is cold-fluid retention above the diaphragm causing dry heaving, vomiting-inducing methods are contraindicated; instead, warming methods should be used, suitable for Sini Tang.
In Shaoyin disease, if the pulse is deep, immediate warming treatment is required, suitable for Sini Tang.
In cases of diarrhea where the patient has an appetite, warming treatment should be applied.
In cases of diarrhea with a slow-tight pulse, pain persists; warming treatment is indicated. If caused by cold, there is abdominal fullness and passage of mucus-like stool.
In cases of diarrhea with a floating-large pulse, this indicates deficiency, often resulting from aggressive purgation. If the pulse becomes floating-leather (Ge) accompanied by borborygmus, warming treatment is indicated, suitable for Danggui Sini Tang (Angelica Sinensis Decoction for Cold Reversal).
In Shaoyin disease with diarrhea, if the pulse is faint-thin-slippery, followed by vomiting, sweating, frequent defecation attempts with little output, warming treatment is indicated.
In Shanghan (Cold Damage) disease, if a physician mistakenly uses purgatives, leading to persistent diarrhea with undigested food and body pain, urgent rescue of the interior is needed, using warming methods, specifically Sini Tang.
A faint-rapid (Wei Shu) pulse is strictly contraindicated for moxibustion. Fire pathogenic factors can cause irritability and rebellious qi, exacerbating both deficiency and excess. This scatters blood within the vessels. Although fire energy is subtle, its internal attack is powerful, potentially charring bones and damaging sinews, making blood recovery difficult.
If the pulse is floating, the exterior should be resolved via sweating. However, if moxibustion is incorrectly applied, the pathogen has no exit and flourishes due to fire. The lower body will become heavy and numb, known as "Fire Rebellion" (Huo Ni). Spontaneous resolution may occur if the patient first feels irritability, followed by sweating. This is inferred from the floating pulse indicating impending sweat resolution. If the pulse is floating with intense heat, applying moxibustion treats an excess pattern as deficiency. The fire agitates the body, leading to dry throat and hemoptysis.
When burning needles (Wen Zhen) induce sweating, if the needle site is exposed to cold and develops nodular redness, Ben Tun (Flying Pig) disease may develop, characterized by qi rushing from the lower abdomen upward. In such cases, apply one moxa cone (Zhuang) to each nodule and administer Guizhi Jia Gui Tang (Cinnamon Twig Decoction plus Cinnamon).
In Shaoyin disease, within one or two days, if the mouth feels neutral (not bitter or dry) and the back feels aversion to cold, moxibustion is indicated.
In Shaoyin disease, if the patient experiences vomiting and diarrhea, but hands and feet are not cold and fever is present, death is unlikely. If the pulse is imperceptible, moxibustion should be applied to Shaoyin points for seven cones.
In Shaoyin disease with diarrhea, faint-thin-slippery pulse, vomiting, sweating, and frequent small bowel movements, warming moxibustion should be applied to upper body points (or fifty cones to Jueyin points). For all types of diarrhea, moxibustion may be applied to Dadun (LR1, 5 cones or 7 cones), Shangqiu (SP5, 3 cones), and Yinlingquan (SP9, 3 cones).
In cases of diarrhea with cold extremities and absent pulse, if the extremities remain cold after moxibustion and slight wheezing occurs, the prognosis is fatal. A weak Shaoyin pulse relative to the Duyang pulse indicates a favorable course.
In Shanghan disease lasting six or seven days, if the pulse is faint, extremities are cold, and the patient is irritable, moxibustion should be applied to Jueyin points. If cold reversal does not occur, the prognosis is fatal.
In Shanghan disease, if the pulse is rapid-forcible (Cu) with cold extremities, moxibustion is permissible, particularly targeting Shaoyin, as Jueyin governs rebellious qi.
