张子和治一女子，年十五，两股间湿癣，长三四寸，下至膝。发痒时，爬搔、汤火俱不解；痒定，
黄赤水出，又痛不可耐。灸 、熏渫，硫黄、 茹、僵蚕、羊蹄根之药，皆不效。其父母来求疗，张
曰∶能从予言则瘥。父母诺之。以排针磨尖快，当其痒处，于癣上各刺百余针，其血出尽，煎盐汤洗
之。如此四次，大病方除。此方不尽以告后人，恐为癣药所误。湿淫于血，不可不砭者矣。
薛立斋治一人，生风癜似癣，三年不愈，五心烦热，脉洪，按之则涩。此血虚之症，当以生血为
主，风药佐之。若专攻风毒，则血愈虚而热愈炽。血被煎熬，则发瘰 ，或为怯症。遂以逍遥散数剂，
及人参荆芥散，二十余剂而愈。
刘禹锡《传信方》云∶予少年曾患癣，初在颈项间，后延上左耳，遂成湿疮浸淫。用斑蟊、狗胆、
桃根诸药，徒令蜇 ，其疮转盛。偶于是州卖药人教用芦荟一两，研，甘草炙半两，相和令匀，先以
温浆水洗癣，乃用旧干帛子拭干，便以二味合和敷，立干瘥，神效。（本草）
立斋治一男子，面青，腿内 患癣，色赤作痒。或为砭刺出血，发热 痛；服消风散而益甚；服
遇仙丹，愈加发热作渴。仍服之，脓水淋漓，其脉洪数，左关为甚。此肝经血虚，火内动，复伤其血
而疮甚。先用柴胡清肝散数剂，又用四物、山栀治之，诸症渐退。用八珍汤、地黄丸，两月余而瘥。
张子和治一童子病，满胸腹湿癣，每爬搔则黄水出，已年余。先以末作丸上涌，次以舟车丸、浚
川散，下三五行。次服凉膈加朴硝，药成，时时呷之，不数日而愈。
Zi Hezi treated a fifteen-year-old girl who suffered from damp tinea (damp-type fungal infection) between her thighs, extending three to four cun in length down to her knees. When the itching occurred, scratching or applying hot water and fire provided no relief; when the itching subsided, yellow fluid would exude, accompanied by unbearable pain. Treatments such as moxibustion, fumigation, and washing, along with herbs like Sulfur (Liu Huang), Sophora Root Bark (Ku Shen), Bombyx Batryticatus (Jiang Can), and Aconite Root (Yang Ti Gen), were all ineffective. The girl's parents came seeking treatment. Zi Hezi said, "If you follow my advice, the disease will be cured." The parents agreed. He sharpened a set of multiple needles and pricked over one hundred times on the affected itchy areas of the tinea until blood was fully discharged, then washed the area with salt water decoction. This process was repeated four times, after which the severe illness was finally eradicated. This method is not fully disclosed to later generations for fear that people might be misled by ordinary tinea remedies. When dampness invades the blood, bloodletting with bian stones (Bian Shi) is indispensable.
Xue Lizhai treated a patient whose body developed wind-like macules resembling tinea, which persisted for three years without healing. The patient experienced heat sensation in the five centers (palms, soles, and chest), with a flooding pulse that felt choppy upon deep pressure. This indicated a syndrome of blood deficiency. The treatment should primarily focus on nourishing blood, assisted by wind-dispelling herbs. If one solely attacks wind-toxin, the blood becomes more deficient and internal heat flares up further. The blood being scorched may lead to scrofula (Luoli) or consumptive diseases (Qie Zheng). Therefore, Xiaoyao Powder (Xiaoyao San) was administered for several doses, followed by Ren Shen Jingjie Powder (Ren Shen Jingjie San), resulting in recovery after more than twenty doses.
Liu Yuxi stated in *Chuan Xin Fang*: "In my youth, I once suffered from tinea, initially appearing on the neck, then spreading to the left ear, eventually becoming an oozing wet sore. I used drugs such as Mylabris (Ban Mao), Dog Gallbladder, and Peach Root, which only caused stinging sensations and worsened the sore. Accidentally, a medicine seller in this prefecture taught me to use Aloe Vera (Lu Hui) one liang, ground into powder, combined evenly with half a liang of roasted Licorice Root (Gan Cao). First, wash the tinea with warm sour rice water, then dry it with an old dry cloth, and apply the mixture of these two ingredients. It dried immediately and healed miraculously." (Cited from *Bencao Gangmu*)
Xue Lizhai treated a man with a bluish complexion and tinea on the inner thigh, which was red and itchy. After someone performed bloodletting with bian stones, he developed fever and pain; taking Xiao Feng San (Wind-Dispersing Powder) aggravated the condition; taking Yu Xian Dan increased fever and thirst. Upon continuing its use, pus and water flowed profusely. His pulse was flooding and rapid, especially at the left guan position. This indicated liver meridian blood deficiency with internal fire stirring, further damaged by treatments that injured the blood, leading to severe sores. Initially, Chai Hu Qing Gan San (Bupleurum Liver-Clearing Powder) was given for several doses, followed by Si Wu Tang (Four Substances Decoction) plus Gardenia (Shan Zhi). Various symptoms gradually receded. Finally, Ba Zhen Tang (Eight Treasures Decoction) and Di Huang Wan (Rehmannia Pill) were used for over two months until recovery.
Zi Hezi treated a young boy suffering from widespread damp tinea covering his chest and abdomen, with yellow fluid exuding upon every scratch, lasting for more than a year. First, emetic pills made from powdered herbs were administered to induce vomiting. Next, Zhou Che Wan (Boat Cart Pill) and Jun Chuan San (River-Dredging Powder) were used to promote bowel movements three to five times. Then, Liang Ge San (Cooling the Chest Powder) with Natrii Sulfas (Pu Xiao) was taken; the decoction was sipped occasionally. Within a few days, he recovered.
