[Etiology] When pathogenic factors invade the skin and are further compromised by wind-cold, wind-scratching urticaria (urticaria caused by wind) arises. If the rash is red, it is due to cold-dampness clashing with heat within the muscles; when the heat becomes excessive, causing strong qi dynamics, the interaction between wind qi and this internal heat results in urticaria, accompanied by bodily itching. The Health Preservation Formula states: one should not sleep outdoors or bathe while sweating, as this may induce chills and fever, manifesting as wind-rash. (From Volume II)
Shen Shi Formula for treating wind-scratching urticaria resembling lacquer dermatitis, accompanied by chest oppression:
Aconiti Lateralis Radix Praeparata (Pao Tianxiong, 炮天雄), Anemarrhenae Rhizoma (Zhimu, 知母), Achyranthis Bidentatae Radix (Niuxi, 牛膝) [each 4 fen], Saposhnikoviae Radix (Fangfeng, 防风) [6 fen], Cinnamomi Cortex (Guixin, 桂心), Isatidis Folium Secatum (Ganlan, 干蓝), Asari Radix (Xixin, 细辛), Ginseng Radix et Rhizoma (Renshen, 人参) [each 3 fen], Trichosanthis Fructus (Gualou, 栝蒌) [5 fen], Atractylodis Macrocephalae Rhizoma (Baizhu, 白术) [8 fen].
The above ten herbs are crushed and sifted. Take half a qianbi (a small measuring spoon) before meals, twice daily. If ineffective, slightly increase the dosage. Avoid pork, raw green onions, raw vegetables, plums, peaches, and sparrow meat.
Another powder formula for treating wind-scratching body urticaria:
Aconiti Radix (Pao Wutou, 炮乌头), Platycodonis Radix (Jiegeng, 桔梗), Asari Radix (Xixin, 细辛), Atractylodis Macrocephalae Rhizoma (Baizhu, 白术) [each 1 liang].
The above four herbs are crushed and sifted. Mix with lead-zhu (red pigment) for color, add four sheng of rice flour, and blend well. Apply the powder to the whole body. (Same as Fan Wang's record, from Volume X)
Qian Jin Formula for treating wind-scratching urticaria:
Achyranthis Bidentatae Radix powder, taken with wine, one fangcunbi (square-inch spoonful) per dose, three times daily. This formula also treats bone and flesh abscesses, epilepsy, and scrofula. (From Volume XXIII)
Yan Nian Shuodiao Ointment for treating body itching, wind-scratching, and urticaria:
Shu Duodenii Radix (cut), Tribuli Fructus (Jilizi, 蒺藜子) [each 1 sheng], Aconiti Radix (Fuzi, 附子), Angelicae Pubescentis Radix (Duhuo, 独活), Rhinocerotis Cornu (Xijiao, 犀角) [crushed], Rosa Multiflorae Radix (Qiangweigen, 蔷薇根), Angelicae Dahuricae Radix (Baizhi, 白芷), Saposhnikoviae Radix (Fangfeng, 防风), Sophorae Flavescentis Radix (Kushen, 苦参), Euphorbiae Humifusae Radix (Jiji, 及己), Cimicifugae Rhizoma (Shengma, 升麻), Ampelopsis Radix (Bailian, 白蔹), Stephaniae Tetrandrae Radix (Fangji, 防己) [each 3 liang], Zanthoxyli Pericarpium (Chuanjiao, 川椒), Maosao Herb (Mangcao, 莽草), Aquilariae Lignum (Qingmuxiang, 青木香), Cnidii Fructus (Shechuangzi, 蛇床子), Ophiopogonis Herba (Shexiancao, 蛇衔草) [each 2 liang], Leonuri Fructus (Chongweizi, 茺蔚子) [cut, 1 sheng], Immature Citrus Fruit (Zhishi, 枳实) [five pieces, roasted], Ilicis Cornuti Caulis (Yinyu, 茵芋) [2.5 liang, cut].
The above twenty-one herbs are cut. Soak them in vinegar overnight until fully submerged. The next morning, place in a copper vessel over charcoal fire, adding five sheng of lard. Boil using the method of "three ups and three downs" (repeated heating and cooling). Stop when Baizhi turns yellow. Strain out the dregs and store the ointment in a non-porous container. Rub onto the skin to treat wind-rash. (Same as Zhang Wenzhong's record)
Another Chongwei Bath Decoction for treating body itching, wind-scratching, or emerging urticaria:
Leonuri Fructus (Chongwei, 茺蔚), Tribuli Fructus (Jilizi, 蒺藜), Pruni Persicae Ramulus (Yangtao, 羊桃), Shu Duodenii Radix (Shuodiaogen, 蒴藋根; leaves are also acceptable), Euphorbiae Humifusae Radix (Louluhao, 漏芦蒿) [each 1 jin], Salt (Sanjin, 盐) [3 jin].
The above six herbs are cut. Boil in three shi of water until reduced to two dan and five dou. Strain out the dregs and dissolve the salt. When the temperature is suitable, eat first, then enter the bath. Prolonged soaking is best. Bathe every night, then lie down immediately after. Protect against wind according to these instructions.
