严冬之夜，触冒风雪，寒毒之气，伤于肌肤，血气壅涩，因即瘃冻， 赤疼肿，便成冻
疮，乃至皮肉烂溃，重者支节堕落。
盛夏之月，人肤腠开，易伤风热，风热毒瓦斯，搏于皮肤，则生沸疮。其状如汤之沸。轻
者，币币如粟粒；重者，热汗浸渍成疮，因以为名。世呼为沸子也。
凡被汤火烧者，初慎勿以冷物，及井下泥、尿泥及蜜淋拓之，其热气得冷即却，
深搏至骨，烂人筋也。所以人中汤火后，喜挛缩者，良由此也。
夫灸疮，脓溃以后，更 肿急痛者，此中风冷故也。
夫灸之法，中病则止，病已则疮瘥。若病热未除，或中风冷，故久不瘥也。
夫针灸，皆是节、穴、俞、募之处。若病甚，则风气冲击于疮。凡血与气，相随而行，
故风乘于气而动于血，血从灸疮处出，气盛则血不止，名为发洪。
凡人被马啮踏，及马骨所伤刺，并马缰、 、勒所伤，皆为毒疮。若肿痛致烦
闷，是毒入腹，亦毙人。
凡人先有疮而乘马，马汗并马毛垢，及马屎尿，及坐马皮鞯，并能有毒，毒瓦斯入疮，致
肿疼痛，烦热，毒入腹，亦毙人。
凡 狗啮人，七日辄一发，过三七日不发，则无苦也。要过百日，方大免耳。当终
身禁食犬肉及蚕蛹，食此，发则死不可救矣。疮未愈之间，禁食生鱼、猪、鸡、腻。过一年
禁之乃佳。但于饭下蒸鱼，及于肥器中食便发。若人曾食落葵得犬啮者，自难治。若疮瘥十
数年后，食落葵便发。
严冬之夜，若触犯冒犯风雪，寒毒之气侵袭肌肤，导致血气运行壅滞涩阻，随即发生冻伤，患处红肿疼痛，形成冻疮；严重时甚至皮肉腐烂溃破，病情极重者会导致肢体关节脱落。
盛夏时节，人体皮肤腠理开泄，容易受到风热之邪的侵害，风热毒气搏结于皮肤，便产生沸疮（一种类似烫伤的水泡状疮疡）。其形态如同沸水翻滚。轻症时，疮疹细密如粟米粒；重症时，因热汗浸渍而形成疮疡，因此得名。世人称之为“沸子”。
凡是遭受开水或火烧伤者，起初务必谨慎，不要用冷物、井底泥、尿泥以及蜂蜜涂抹覆盖患处。因为热气遇到寒冷就会退缩内陷，深透至骨骼，腐蚀人的筋脉。所以人被汤火烫伤后，喜欢出现肌肉挛缩的现象，正是由于这个原因。
做灸法留下的灸疮，在脓液溃破之后，如果再次出现肿胀急迫疼痛，这是感受了风冷之邪的缘故。
灸法的运用原则是：病中则止，疾病痊愈则疮口愈合。如果体内的热邪未除，或者又感受了风冷之邪，所以伤口长久不能愈合。
针灸治疗，都是作用于经络的节、穴、俞、募等部位。如果病情严重，风气会冲击疮口。凡血与气，是相伴而行的，所以风邪乘袭气分并扰动血分，血液从灸疮处流出，若气盛则血液不止，这种情况称为“发洪”。
凡是被人被马咬伤、踩踏，或被马骨刺伤，以及被马缰绳、马鞭、马勒等器具所伤，都会形成毒疮。如果出现肿痛导致烦闷的症状，说明毒气已入腹，也可能导致死亡。
凡是人原本就有疮口却去骑马，马汗、马毛污垢，以及马屎尿，还有坐在马皮做的鞍垫上，这些都能产生毒性，毒气侵入疮口，导致肿胀疼痛、烦热，若毒气入腹，也会导致死亡。
凡是狗咬伤人，每隔七天就会发作一次，如果过了二十一天不再发作，就没有大碍了。但要过一百天，才能完全免除祸患。应当终身禁止食用犬肉和蚕蛹，如果吃了这些食物，一旦发作，死亡无法救治。在疮口未愈合期间，禁止食用生鱼、猪肉、鸡肉及油腻食物。最好禁食一年才好。只要在饭下蒸鱼，或在肥腻器皿中进食就会诱发。如果有人曾吃过落葵（木耳菜）后又遭到狗咬，自然难以治疗。即使疮口愈合十数年后，吃落葵也会诱发。
On cold winter nights, exposure to wind and snow allows the pathogenic cold-toxin qi to invade the skin and muscles. This causes stagnation and obstruction of blood and qi, leading immediately to frostbite (frost injury). The affected area becomes red, painful, and swollen, forming a frostbite sore (chilblain). In severe cases, the skin and flesh may rot and ulcerate, and in extreme cases, limbs or joints may fall off.
During the midsummer months, human skin pores are open, making one susceptible to wind-heat pathogens. When wind-heat toxin qi combats with the skin, it generates "boiling sores" (a type of blistering sore resembling scalds). The appearance resembles boiling water. In mild cases, the lesions are dense like millet grains; in severe cases, hot sweat macerates the skin to form sores, hence the name. The world calls this "Feizi" (Boiling Seeds).
For those burned by boiling water or fire, one must initially be cautious not to apply cold objects, well-bottom mud, urine-mud, or honey to cover the wound. Because heat energy retreats upon contact with cold, driving it deep into the bones and rotting the tendons. Therefore, after being scalded by hot water or fire, patients often experience muscle contraction/spasm, which is precisely due to this reason.
After moxibustion sores have suppurated and ruptured, if swelling and urgent pain recur, this is caused by contracting wind-cold.
The principle of moxibustion is: stop when the disease is addressed; once the disease is cured, the sore heals. If the internal heat has not been eliminated, or if wind-cold is contracted, the sore will fail to heal for a long time.
Acupuncture and moxibustion target specific locations such as Joints, Shu-Points, Mu-Points, and Cuo-Points on the meridians. If the condition is severe, wind qi attacks the sore. Blood and Qi travel together; thus, when wind invades Qi and agitates Blood, blood flows from the moxibustion sore. If Qi is excessive, blood flow does not stop, a condition named "Fa Hong" (Erupting Flood).
Injuries caused by horse bites, trampling, puncture by horse bones, or trauma from horse reins, whips, and bridles all result in toxic sores. If swelling and pain lead to irritability and distress, it indicates that the toxin has entered the abdomen, which can also be fatal.
If a person with an existing sore rides a horse, the horse's sweat, dirty hair, feces, urine, and the leather saddle pad can all generate toxicity. Toxic qi enters the sore, causing swelling, pain, irritability, and fever. If the toxin enters the abdomen, it can be fatal.
When a dog bites a person, symptoms tend to flare up every seven days. If no flare-up occurs after three weeks (21 days), there is little cause for concern. However, one must wait until 100 days have passed to be fully safe. One should strictly avoid consuming dog meat and silkworm pupae for life; consuming these can trigger a fatal attack. During the period before the sore heals, raw fish, pork, chicken, and greasy foods are prohibited. It is best to abstain for a year. Even steamed fish served under rice or food eaten from greasy vessels can trigger recurrence. If a person who has consumed Malva verticillata (Okra/Leaf Mallow) is bitten by a dog, it is difficult to treat. Even if the sore heals, consuming Malva verticillata ten years later can still trigger a recurrence.
