《黄帝内经·素问·六元正纪大论》中关于五运六气的论述指出：丹毒（一种皮肤红肿热痛的疾病）的病机属性皆归属于火。经文说：“少阳相火司天之年，客气胜则导致丹疹外发，以及出现丹毒症状。”
《太平圣惠方》记载：凡是各种丹毒，都是人体身体突然变得像丹砂一样赤红，所以称为丹毒。有的发作在手脚，有的发作在腹部，大小如手掌，这都是由风热恶毒邪气所致，严重的也有类似疽的病变。如果不紧急治疗，疼痛将难以忍受，时间久了则会溃烂流脓血数升。如果发作在关节之间，就会使人四肢肿胀有毒；邪气侵入肠道则会导致死亡，小儿患此病最为急重。戴复庵说：丹毒发作时的颜色和形态不一，瘙痒和疼痛的表现也不同，大概都是因为血热、肌肤虚弱，风邪搏结而引发。其中颜色发红的较多，因为红色所以称为丹。适宜使用消风散，加入烧枫树子（保留药性，研成粉末），用酒调服。有发作时颜色发白的，称为“冷丹”。适宜用消风散混合黑神散，用酒调服。这种病多是因为肌肉腠理疏松，被风邪侵袭而成，感受风热则色赤，感受风寒则色白。现在的人只把红色的叫作丹，白色的叫作瘼（此处指白色丹毒或瘾疹类病症），所以有些人服用土朱（赤石脂）并用酒调服而痊愈，这也是因为脾主肌肉，土能入脾，各从其类的缘故。古方也称之为瘾疹，不仅区分寒热，也兼备四气（风、寒、暑、湿）。近世的方论称白色的为“白婆瘼”（即白丹），红色的为“血风”。赤色和白色两种证型都可以使用乌药顺气散，配合消风散用酒调服。白色者多用顺气散，红色者多用消风散，患有此病的人都适宜服用藿香正气散煎剂。有人一生都不能吃鸡肉及獐鱼等动风的食物，一吃丹毒就随即发作，由此可以看出这是脾风所致。脾主管身体的肌肉，藿香正气散是治疗脾病的药物，而土朱也是入脾的药物，这个方子屡试屡验。朱丹溪说：内伤导致的斑疹，是因为胃气极度虚弱，一身之火游行于体表所致，适宜用补益法以降火。我曾治疗一名中年男子，痈疽溃破后发热干呕，背部发出丹毒，用了各种敷贴丹毒的药，又用刀在每个丹头刺破出血，但丹毒都不消退。后来用半夏、陈皮、生姜加上补益药剂，治疗呕吐无效，于是单纯重用人参半两，当归、白术各钱半，浓煎一帖，呕吐停止，两三帖后丹毒逐渐缓解，热势渐减，大约五十多帖后热势才完全消除，神气才恢复。

According to the discussion on the Five Movements and Six Qi in *Huangdi Neijing* (Yellow Emperor's Inner Canon), Dan Du (a skin disease characterized by redness, swelling, heat, and pain) is pathogenically attributed to Fire. The classic states: "In years when Shaoyang Ministerial Fire governs the sky, if the guest pathogen prevails, it leads to the external eruption of Dan Zhen (red rashes) and the appearance of Dan Du symptoms."
*Tai Ping Sheng Hui Fang* records: All types of Dan Du are conditions where the body suddenly turns red like cinnabar, hence the name Dan Du. It may erupt on the hands and feet, or on the abdomen, with lesions the size of a palm. These are all caused by toxic wind-heat pathogens; severe cases may resemble Ju (deep-seated suppurative infections). If not treated urgently, the pain becomes unbearable, and over time, ulceration occurs with the discharge of pus and blood. If it erupts between joints, it causes toxic swelling in the four limbs; if the pathogen enters the intestines, it can be fatal. Children suffering from this condition face the most acute danger. Dai Fu'an stated: The color and shape of Dan Du eruptions vary, as do the sensations of itching and pain. Generally, they arise from the interaction of blood heat, deficient muscle tissue, and wind pathogens. Red eruptions are more common, and because of their red color, they are called Dan. The appropriate formula is Xiaofeng San (Wind-Dispersing Powder), mixed with burnt Fengshuizi (Fructus Aceris, preserved for its medicinal properties) and taken with wine. Eruptions that appear white are called "Leng Dan" (Cold Dan). The appropriate treatment is Xiaofeng San mixed with Heishen San (Black Divine Powder), taken with wine. This disease often results from loose muscle texture allowing wind pathogens to invade. Wind-heat causes redness, while wind-cold causes whiteness. Nowadays, people only refer to red eruptions as Dan and white ones as Mo (referring to white Dan Du or urticaria-like conditions). Therefore, some recover after taking Tuzhu (Hematitum, red ochre) mixed with wine, which works because the Spleen governs muscles, Earth enters the Spleen, and things follow their own kind. Ancient texts also call this Yinzhen (urticaria), distinguishing not only cold and heat but also the Four Qi (wind, cold, summer-heat, dampness). Recent medical theories refer to white eruptions as "Baipo Mo" (white Dan) and red ones as "Xuefeng" (Blood Wind). Both red and white syndromes can be treated with Wuyao Shunqi San (Aucklandia and Cyperus Powder to Promote Qi Circulation) combined with Xiaofeng San, taken with wine. White cases mostly use Shunqi San, while red cases mostly use Xiaofeng San. Patients with this condition should generally take Huoxiang Zhengqi San (Agastache Powder to Rectify the Qi). Some individuals must never consume chicken, zhang fish, or other wind-aggravating foods; eating them triggers immediate Dan eruptions, indicating this is Spleen Wind. The Spleen governs the body's muscles. Huoxiang Zhengqi San treats Spleen diseases, and Tuzhu also enters the Spleen; this formula has proven effective repeatedly. Zhu Danxi stated: Spots caused by internal injury result from extreme deficiency of Stomach Qi, causing the fire of the whole body to wander externally. It is appropriate to use tonification to descend the fire. I once treated a middle-aged man who, after an abscess ruptured, suffered fever and dry retching, with Dan erupting on his back. Various topical Dan medicines were applied, and knives were used to bleed each Dan head, but the Dan did not recede. Later, Banxia (Pinelliae Rhizoma), Chenpi (Citri Reticulatae Pericarpium), and Shengjiang (Zingiberis Rhizoma Recens) were added to tonifying agents, but vomiting persisted. Finally, pure Ginseng Radix et Rhizoma (5 liang), Danggui Radix (1.5 qian), and Baizhu Rhizoma (1.5 qian) were decocted strongly in one dose; vomiting stopped. After two or three doses, the Dan gradually eased, and fever subsided. After about fifty doses, the fever was completely eliminated, and spirit recovered.
Jinhua San (Golden Flower Powder): Treats all types of Dan Du, characterized by heat, pain, and redness.
Ingredients: Jinyu (Curcumae Aromatae Rhizoma), Huanglian (Coptidis Rhizoma), Huangqin (Scutellariae Radix) (each 1 liang); Nuomi (Oryza Sativa Glutinosa) (3 he).
Preparation and Administration: Grind into fine powder. For each use, mix with honey water to form a paste. Apply to the Dan area with a chicken feather; change when dry.
Treats all types of Dan Du with toxic qi attacking and piercing, causing red swelling and unbearable pain. (*Jianyao Jizhong Fang*)
Ingredients: Cheqiancao (Plantaginis Herba), Yimumcao (Leonuri Herba), Dichancao (Achyranthis Bidentatae Radix).
Preparation and Administration: Equal parts. Mash and grind until soft, then apply. Reapply when dry. (If fresh herbs are unavailable, use dried herbs ground into powder and mixed with cold water.)
Treats all types of Dan Du with toxic qi, presenting with five colors changing unpredictably. If not treated immediately, pain becomes unbearable. If the skin breaks down, pus and blood discharge; if it erupts at joint fissures, it may lead to limb necrosis. This is likely a type of Ju and requires rapid treatment.
Ingredients: Dasuan (Allii Sativi Bulbus) or Xiaoasuan (Allii Macrostemonis Bulbus).
Preparation and Administration: Pound into a paste. Apply thickly. Reapply when dry, until healed.
Another Formula: Chixiaodou (Vigna Semen Rubrum) (1 sheng); Yangjiao (Cornu Bubali) (burnt to ash, 0.5 liang).

Ingredients: Yuntaizi (Brassicae Napus Semen) (1 liang).
Preparation and Administration: Mix with one large cup of wine, grind, filter dregs, and boil for five to seven boils. Take one she warm at any time. Sun Simiao said: A miraculous formula for treating Dan Du: mash Yuntaizi leaves and apply; healing follows immediately. If not cured, continue application within three days. In the 17th year of Zhenguan (March 8), in Neijiang County, due to excessive drinking at night, I felt pain in the bones and flesh of my four limbs while sleeping, experienced dizziness and headache, and had a swelling on the forehead the size of a bullet, too painful to touch. By noon, the pain spread to the right corner; by night, it affected all areas, closing my eyes so I could not open them, nearly leading to death. The county magistrate, Mr. Zhou, tried various medicines without success for seven days. I formulated this prescription myself, and its effect was miraculous. Thus, I recorded it for dissemination. Additionally, the Dai Xing family secret formula states: If green Yuntaizi is unavailable, use dried powder mixed with water. For any Dan Du covering the body or surrounding the waist and abdomen, resistant to hundreds of treatments, this formula alone can cure it, treating twenty-four types of Dan Du.

Sun Simiao said: Dan Du is also called Tianhuo (Heavenly Fire). Suddenly, red patches like cinnabar appear on the flesh. Large lesions are palm-sized; severe cases cover the whole body. There may be itching and swelling, with no fixed color. There may be Bai Dan (White Dan), where flesh swells, itches, then hurts, appearing slightly swollen like blown urticaria. There is also Jiguan Dan (Chicken Comb Dan), which rises red, large as a coin, small as hemp seeds, resembling chicken comb color with rough skin, also known as Zhuyu Dan. There may be Huo Dan (Fire Dan) or Shui Dan (Water Dan), erupting all over the body. When encountering dampness/water, it appears yellowish, as if water is under the skin. It favors the eyes and yin organs. Although a minor illness, it can be fatal.
