孙真人论曰∶《素问》云，风邪客于肌中则肌虚，真气发散，又被寒搏皮肤，外发腠
理，开毫毛，淫气妄行之则为痒也。所以有风疹瘙痒，皆由于此。又有赤疹者，忽然起
如蚊虫咬，烦痒极者，重抓疹起，搔之逐手起。又有白疹者发冷；亦有赤疹，盖赤疹者
发热。 夫风瘾疹者，由邪气客于皮肤，复遇风寒相搏，则为瘾疹。若赤疹者，由冷湿
搏于肌中，风热结成赤疹也。遇热则极，若冷则瘥也。白疹者，由风气搏于肌中，风冷
结为白疹也，遇冷则极，或风中亦极，得晴明则瘥，着浓暖衣亦瘥也。其脉浮而洪，浮
则为风，洪则为气，风气相搏，则成瘾疹；致身体为痒也。 丹溪云∶疹属热与痰，在肺
清火降痰，或解散出汗，亦有可下者。 疹在表者，消毒饮子、防风通圣散。在里者，大
柴胡汤、四顺饮子。虚者补中益气汤。皆同伤寒施治也。 朱院君三十余，久患瘾疹，身
痹而紫色，可与防风通圣散加牛蒡子为极细末。每二钱，水盏半，入姜汁令辣，煎；食
前、热饮之。
或问斑疹何如？曰∶方论皆谓缘肌中有湿，若凉热之气所折，热结不散则成赤疹。若
因风邪所折，风热相搏则成白疹。赤疹得热则剧，得冷则减，盖热气郁于内，故恶热宜
冷。白疹得阴雨则甚，得晴则消，盖热气散释于外，故恶冷宜热。热搏于血分，其邪因
并发于表则赤。若风湿搏于气分，则气液不行，因邪并发于表则白。夫如是然后与治法
相应，邪热者，故恶热而喜凉。邪湿者，故恶雨而喜晴矣。方论中又有风痘 者，即
《内经》所谓汗出见湿，乃生痤痱。又曰∶劳汗当风，寒薄为郁乃痤痱，即瘾疹属也。 ，
类也，此皆谓外邪郁肌肉玄府之热者矣。然则与《内经》言少阳少阴而君相二火，
客热之胜为丹疹外发者，方论中则无有也。故人气、君相二火郁发而变者，宜乎未之及耳。
若此条是人气所变之一者也。故二火郁发出血气之表，与外邪所郁无异。更有小儿发痘
疮之外必有出疹二次，亦是君相二火发出未尽之胎毒也。

孙思邈论述道：《素问》说，风邪侵入肌体内部导致肌肉虚弱，真气外散，又受寒气搏击皮肤，向外发散至腠理，使毫毛张开，淫乱之气妄行从而产生瘙痒。所以出现风疹瘙痒，都是由于这个原因。又有赤疹，突然发作像蚊虫叮咬一样，烦躁瘙痒极其严重，用力抓挠后疹子隆起，搔抓时疹子随之而起。又有白疹，发作时会发冷；也有赤疹，赤疹发作时会发热。所谓风瘾疹，是由于邪气客居在皮肤，再次遇到风寒相互搏击，就形成瘾疹。如果是赤疹，是由于冷湿搏击于肌肉之中，风热结合形成赤疹。遇到热邪则症状加剧，遇到寒冷则病情好转。白疹，是由于风气搏击于肌肉之中，风冷结合形成白疹，遇到寒冷则症状加剧，或者在风中也会加剧，遇到晴天则好转，穿着厚暖的衣服也会好转。其脉象浮而洪大，浮表示有风，洪大表示有气（邪气），风与气相互搏击，就形成瘾疹，导致身体瘙痒。朱丹溪说：疹属于热和痰，治疗应在肺经清火降痰，或者解散表邪出汗，也有可以用下法治疗的。疹在表位的，用消毒饮子、防风通圣散。在里位的，用大柴胡汤、四顺饮子。虚证的，用补中益气汤。治疗方法都与伤寒病相同。朱院君三十多岁，长期患瘾疹，身体麻木且呈紫色，可用防风通圣散加牛蒡子研成极细粉末。每次服用二钱，用水一盏半，加入姜汁使其辛辣，煎煮；饭前热服。
有人问斑疹是怎么回事？回答说：方书理论都认为因为肌肉中有湿气，若被凉热之气所折损，热结不散就形成赤疹。如果因风邪所折损，风热相互搏击就形成白疹。赤疹遇热则加重，遇冷则减轻，这是因为热气郁结在体内，所以厌恶热而适宜冷。白疹遇阴雨天气则严重，遇晴天则消退，这是因为热气散发到体外，所以厌恶冷而适宜热。热邪搏结于血分，邪气因而并发于体表则表现为红色。如果风湿搏结于气分，则气液运行不畅，邪气因而并发于体表则表现为白色。像这样然后与治疗方法相应，邪热者，所以厌恶热而喜欢凉。邪湿者，所以厌恶雨天而喜欢晴天了。方书中又有“风痘”这一说法，即《内经》所说的汗出见湿，乃生痤痱。又说：劳作出汗当风，寒气迫近成为郁结乃生痤痱，这属于瘾疹一类。类同于此，这都是指外邪郁积在肌肉玄府的热邪。然而这与《内经》所说的少阳、少阴以及君相二火，客热胜复导致丹疹外发的情况不同，方书中没有提到这些。所以人气、君相二火郁结发作而变化的情况，恐怕没有被提及。如果这条内容是人气变化的一种。所以二火郁结发出气血之表，与外邪郁积没有区别。更有小儿发痘疮之外必会有二次出疹，这也是君相二火发出未尽的胎毒所致。
初虞世治疗皮肤风热，遍身生出瘾疹。用牛蒡子、浮萍各等分，用薄荷汤调服二钱，每日两次服用。苦参丸（出自《衍义》）有人患病遍身风热细疹。痒痛难以忍受，连头部、小腿、肚脐、腹部及隐蔽部位都如此，涎痰也多，夜间无法入睡。用苦参末一两，皂角二两，水一升揉搓过滤取汁，用银石器熬成膏，与苦参混合制成如梧桐子大小的丸药。饭后温水送服二十丸，第二天就好了。
《千金方》的治疗法则，白疹适宜用矾石汁擦拭。或者煮蒴藋加少量酒来洗浴效果良好。（姚氏用来治疗赤疹），或者煮石南汁擦拭效果良好。或者用水煮鸡屎汁擦拭。其余一切如同治疗丹毒的方法。俗称风屎，也叫风尸。症状严重的用石南汤主治。

Sun Simiao discussed: The *Suwen* (Basic Questions) states that when wind pathogen invades the interior of the muscles, the muscles become deficient, and the true qi scatters outward. If it is then combated by cold at the skin, it disperses outward to the interstices (couli), opens the hair follicles, and allows chaotic qi to move recklessly, resulting in itching. Therefore, wind urticaria with itching arises from this cause. There is also red urticaria, which suddenly appears like mosquito bites, causing extreme irritability and itching; vigorous scratching causes the rash to rise, and scratching makes it appear instantly. There is also white urticaria, which presents with chills upon onset; conversely, red urticaria presents with fever. Wind urticaria occurs when pathogenic factors reside in the skin and are subsequently combined with wind-cold, forming urticaria. Red urticaria results from cold-dampness combating within the muscles, where wind-heat combines to form red urticaria. Symptoms worsen with heat and improve with cold. White urticaria results from wind qi combating within the muscles, where wind-cold combines to form white urticaria. Symptoms worsen with cold or exposure to wind, but improve on sunny days or with warm clothing. The pulse is floating and surging; floating indicates wind, and surging indicates qi (pathogenic factor). When wind and qi combat each other, urticaria forms, causing body itching. Zhu Danxi stated: Urticaria belongs to heat and phlegm; treatment should clear fire and descend phlegm in the Lung, or release the exterior through sweating, or there may be cases suitable for purgation. For urticaria at the exterior level, use Xiaodu Yinzi (Disinfecting Decoction) or Fangfeng Tongsheng San (Saposhnikovia Decoction for Unblocking the Hinges). For urticaria at the interior level, use Da Chaihu Tang (Major Bupleurum Decoction) or Sishun Yinzi (Four-Smooth Decoction). For deficiency patterns, use Buzhong Yiqi Tang (Tonify the Middle and Augment the Qi Decoction). The treatment methods are the same as those for Shanghan (Cold Damage). Master Zhu Yuanjun, in his thirties, suffered from chronic urticaria with body numbness and a purple hue; he was treated with Fangfeng Tongsheng San added with Niubangzi (Arctii Fructus), ground into an extremely fine powder. Two qian were taken each time, decocted in one and a half cups of water with ginger juice until pungent, and taken hot before meals.
Someone asked about macules and papules. The answer was: Formulary theories state that moisture in the muscles, if constrained by cool or hot qi, leads to heat accumulation without dispersion, forming red urticaria. If constrained by wind pathogen, wind-heat combats to form white urticaria. Red urticaria aggravates with heat and alleviates with cold because heat is stagnant internally, thus disliking heat and favoring cold. White urticaria worsens on rainy days and resolves on sunny days because heat dissipates externally, thus disliking cold and favoring heat. Heat combing the Blood level causes pathogens to manifest at the exterior as red. Wind-damp combing the Qi level impedes Qi and fluid movement, causing pathogens to manifest at the exterior as white. Thus, treatments correspond accordingly: for pathogenic heat, one dislikes heat and prefers cool; for pathogenic dampness, one dislikes rain and prefers sun. Formularies also mention "wind acne," which refers to what the *Neijing* calls "acne and prickly heat arising from sweat exposed to dampness." It also says "sweat from labor exposed to wind, compressed by cold leading to stagnation, causes acne and prickly heat," which belongs to the category of urticaria. These all refer to heat stagnating in the muscle pores due to external pathogens. However, this differs from the *Neijing*'s discussion on Shaoyang and Shaoyin, and the Ministerial Fire and Sovereign Fire, where excessive guest heat causes Danzhen (red rash) to erupt externally, which is not mentioned in formularies. Therefore, changes caused by human Qi and the stagnation/emission of Ministerial and Sovereign Fires were likely omitted. This condition is one such variation. Thus, the emission of the two fires affecting the Qi and Blood at the exterior is no different from external pathogen stagnation. Furthermore, children developing chickenpox often have a secondary eruption of rashes, which is also due to fetal toxins not fully expelled by the Ministerial and Sovereign Fires.
Chu Yushi treated skin wind-heat with generalized urticaria using equal parts of Niubangzi (Arctii Fructus) and Fuping (Marsilea Ventralis), administered as two qian mixed with Bohe Tang (Mint Decoction), twice daily. Kushen Wan (Bitter Coptis Pill, from *Yanyi*) was used for someone suffering from generalized fine wind-heat rashes. The itching and pain were unbearable, affecting the head, shins, umbilicus, abdomen, and private areas, accompanied by excessive saliva and phlegm, and insomnia at night. One liang of Kushen (Sophorae Radix) powder and two liang of Zaojiao (Gleditsiae Fructus) were rubbed in one sheng of water, filtered, and boiled in silver/copper vessels to form a paste, mixed with Kushen to make pills the size of paulownia seeds. Twenty pills were taken with warm water after meals, curing the patient the next day.
The *Qianjin Fang* (Essential Prescriptions Worth a Thousand Gold) treatment principles suggest wiping white urticaria with Fanshi Zhi (Alumen Juice). Alternatively, bathing with Suoluo (Akebiae Caulis) and a little wine is beneficial. (Yao Shi used this for red urticaria).
