有人患遍身风热细疹，瘙痒疼痛难以忍受，皮疹连及胸部、胫部、脐腹部以及近隐处皆然，痰涎也多，夜间无法入睡。用苦参末一两、皂角二两，加水一升，揉搓过滤取汁，在银或石器中熬成膏，与苦参末混合制成梧桐子大小的丸药，每次服用三二十丸，温水送服，食后次日即愈。
有一位妇人患脐下腹部上下连及二阴，遍满生湿疮，如马瓜疮，他处并无此症，仅觉痒热而痛，大小便涩滞，流出黄汁，食欲也减退，身体面部微肿。医生当作恶疮治疗，使用鳗鲡鱼、松脂、黄丹等药物涂敷，疮虽愈但热痛更甚，这是因为治疗不对症所致。询问得知此人嗜酒，贪吃喜欢鱼类等发风之物。急忙令其用温水洗拭去除膏药，随即取马齿苋四两烂研细，加入青黛一两再研匀，涂敷于疮上，实时热减痛痒皆去。同时内服八正散，每日三次，以分散客热。每次涂药需等待一时辰左右，待药已干燥，再涂新的湿药。如此反复，二日后减轻三分之一，五日后减轻三分之二，自此二十日痊愈。痊愈后问曰：此疮为何至此？答曰：中下焦蓄积风热毒瓦斯，若不出则当发为肠痈、内痔。仍须常禁酒及发风之物。然而不能禁酒，果然患内痔。（出自《本草衍义》）
践踏坏灶土令人患疮，踩踏鸡蛋壳令人得白癜风。
皇中学究任道腿间患一疮，始发赤肿，后绝便变黑，后穴则有黄水出，四边浮浆起，累治不瘥。医王通看之，此疮狭长似鱼脐下疮也。遂以大针针四向并中，随针有紫赤水汁出如豆汁。言此一因风毒蕴结而成，二因久坐血气凝涩而致，三因食肉有人汗落其间也。道曰素好读书而久坐，此疾数岁前夏月道中买猪脯味水饭疑似人肉食以后得斯疾。通曰与误食人汗不远矣。以一异散子用鸡子清调敷其疮，日三易，数日得愈。道坚求其方，通曰止用雪玄一味，自后累访名医求其雪玄何物，医皆不识。道因至许郑间会医者郝老曰尝记圣惠有一方治此疾用腊月猪头烧灰以鸡子清调敷此乃是也。雪玄非郝老博学多记后医岂不惑耶（出自《名医录》）
A patient suffered from widespread wind-heat fine rashes, with unbearable itching and pain. The rash extended to the chest, shins, umbilical region, abdomen, and areas near the genitals. There was also excessive phlegm-saliva, and inability to sleep at night. One tael of *Sophora flavescens* root powder (Kushen) and two taels of *Gleditsia sinensis* fruit powder (Zaojiao) were mixed with one sheng of water, rubbed and filtered to extract the juice. The juice was boiled into a paste in silver or ceramic vessels, then mixed with the *Sophora* powder to form pills the size of tung tree seeds. Thirty to twenty pills were taken each time with warm water after meals, resulting in recovery the next day.
A woman suffered from wet sores covering the area below the umbilicus, extending upwards and downwards to include both yin organs. The sores resembled those of "horse melon sores," with no such symptoms elsewhere, only accompanied by itching, heat, and pain. Urination and defecation were obstructed, yellow fluid was discharged, appetite decreased, and there was slight swelling of the body and face. Physicians treated it as a malignant sore, applying medicines such as eel, pine resin, and lead oxide. Although the sores healed, the heat and pain worsened due to incorrect treatment. Upon inquiry, it was found that she enjoyed drinking alcohol and eating fish and other foods that trigger wind. She was immediately instructed to wash off the ointment with warm water. Then, four taels of fresh *Portulaca oleracea* (Pusongcai) were mashed finely, mixed with one tael of Indigo naturalis (Qingdai), ground evenly, and applied to the sores. Heat, pain, and itching subsided instantly. Internally, *Bazheng San* (Eight-Herb Powder for Unblocking) was administered three times daily to dissipate external pathogenic heat. Each application required waiting for about one double-hour (shi) until the medicine dried, followed by a new wet application. After two days, the condition improved by one-third; after five days, by two-thirds. Full recovery took twenty days. When asked why this sore occurred, the answer was: accumulation of wind-heat toxic qi in the middle and lower jiao. If not expelled, it would lead to intestinal abscess or internal hemorrhoids. Alcohol and wind-triggering foods must be strictly avoided. However, since she could not abstain from alcohol, she indeed developed internal hemorrhoids. (From *Bencao Yan Yi*)
Stepping on ruined hearth soil can cause sores; stepping on chicken eggshells can lead to vitiligo (white depigmentation).
Ren Dao, a scholar at Huang Middle School, suffered from a sore between his legs. Initially red and swollen, it later turned black upon cessation of bowel movements. Yellow fluid exuded from the posterior aperture, with floating pus around the edges. Multiple treatments failed. Physician Wang Tong examined it, noting the sore was narrow and long, resembling a "fish-umbilicus sore." He punctured the four directions and center with a large needle, releasing purple-red watery fluid resembling bean curd dregs. He explained three causes: 1) accumulation of wind-toxin; 2) blood and qi stagnation due to prolonged sitting; 3) human sweat falling onto meat consumed. Ren Dao stated he loved reading and sitting for long periods. Years prior, in summer, he bought pork jerky on the road, which tasted like rice mixed with human sweat, suspecting he had eaten meat contaminated by human sweat. Wang Tong replied this was close to accidentally ingesting human sweat. An "Extraordinary Powder" (Yi San Zi) mixed with egg white was applied to the sore, changed three times daily, leading to recovery in a few days. Ren Dao insisted on knowing the formula. Wang Tong said it contained only one ingredient: "Xue Xuan." Subsequent inquiries among famous physicians yielded no knowledge of what "Xue Xuan" was. Later, in Xu and Zheng regions, Ren Dao met an old physician named Hao, who recalled a prescription from *Taiping Shenghui Fang* treating this condition using ash from a pig's head burned in the twelfth lunar month, mixed with egg white. Thus, "Xue Xuan" referred to this ash. Without Hao's erudition and memory, subsequent physicians would surely have been confused. (From *Ming Yi Lu*)
