【注】此证俗称为“鬼饭疙瘩”。由出汗后受风，或在露天处睡觉乘凉，导致风邪容易侵袭体表虚弱之人。初起时皮肤发痒，随后出现扁平的疙瘩，形状像豆瓣，堆积成片。白天瘙痒严重的，适宜服用秦艽牛蒡汤；夜间瘙痒严重的，适宜服用当归饮子。外用烧酒浸泡百部，用蓝布蘸取药酒擦拭，注意避免风吹受凉，自然见效。

【方歌】浸淫疮由火、湿、风三邪引发，渗出黄水蔓延，形态类似疥疮，蔓延成片且瘙痒不止，治疗宜清热并祛风。
【注】此病初起类似疥疮，随时搔痒，蔓延不止，抓破后流出黄水，浸淫成片，由心火、脾湿兼受风邪而成。《内经》云：岁火太过，严重时身体发热，肌肤浸淫溃烂。张仲景说：病变从口部流向四肢的为顺证，从四肢流入口部的为逆证。初期服用升麻消毒饮，加苍术、川黄连。若抓破流血，适宜服用消风散，外涂青蛤散即可痊愈。如果脉象迟滞且不能进食，黄水不止，这属于脾脏败坏，是不治之症。
[Prescription Verse] Lei (a type of skin eruption resembling broad beans) arises from wind pathogen invasion during sweating. Its appearance resembles broad beans or the shape of thunder stones. For those with severe itching during the day, Qinjiao Tang is suitable; for those with worsening symptoms at night, Danggui Yin should be taken to bring relief.
[Annotation] This condition is colloquially known as "Ghost Rice Wheals." It is caused by catching wind after sweating, or sleeping outdoors in the cool air, where wind pathogens easily attack individuals with deficient exterior defenses. Initially, the skin itches, followed by the emergence of flat wheals resembling broad beans, accumulating into patches. For severe daytime itching, Qinjiao Niubang Tang is indicated; for severe nighttime itching, Danggui Yinzi is indicated. Externally, soak Baibu (Stemonae Radix) in distilled spirits, dip blue cloth in the liquor, and rub the affected area. Strictly avoid wind and cold for effective results.
Formula: Qinjiao Niubang Tang
Composition: Qinjiao (Gentianae Rhizoma et Radix, 1.5 qian), Niubanzi (Fructus Arctii, stir-fried and crushed), Zhike (Aurantii Fructus, bran-fried), Mahuang (Ephedrae Herba, honey-fried), Xijiao (Rhinocerotis Cornu, shaved), Huangqin (Scutellariae Radix), Fangfeng (Saposhnikoviae Radix), Gancao (Glycyrrhizae Radix et Rhizoma, raw), Heishen (Rehmanniae Radix Preparata), Shengma (Cimicifugae Rhizoma, each 1 qian).
Decoct two zhong of water until reduced to eight fen, and take orally.
[Prescription Verse] Qinjiao Niubang Tang treats wind lingering in the skin causing Lei eruptions resembling hemp seeds or beans. The formula contains Zhike, Mahuang, Xijiao (shaved), Huangqin, Fangfeng, Gancao, Heishen, and Shengma.
Another Formula: Danggui Yinzi (See Scabies section)
[Prescription Verse] Jinying Chuang (Oozing Eczema) is triggered by fire, dampness, and wind. Yellow fluid oozes and spreads, resembling scabies, spreading into patches with incessant itching. Treatment should focus on clearing heat and dispelling wind.
[Annotation] This disease initially resembles scabies, with constant itching that spreads uncontrollably. Scratching causes yellow fluid to ooze, leading to extensive oozing patches. It is caused by Heart Fire, Spleen Dampness, and Wind pathogen invasion. The Classic states: When annual Fire is excessive, severe cases present with body heat and skin oozing lesions. Zhang Zhongjing stated: Lesions spreading from the mouth to the limbs are favorable (Shun); those spreading from the limbs to the mouth are unfavorable (Ni). Initially, administer Shengma Xiaodu Yin with added Cangzhu (Atractylodis Rhizoma) and Chuan Huanglian (Coptidis Rhizoma). If scratching breaks the skin and causes bleeding, Xiaofeng San is indicated, along with external application of Qingge San for cure. If the pulse is slow and the patient cannot eat, with continuous oozing of yellow fluid, this indicates Spleen failure, which is an incurable condition.
Formula: Shengma Xiaodu Yin (See Impetigo section)
Xiaofeng San (See Neck Button Wind section)
Qingge San (See Nasal An Bi section)
