〔戴人〕：有一名十五岁女子，大腿内侧患湿癣，长度三四寸，向下延伸至膝盖。发作时瘙痒，抓挠、热水烫洗均不能缓解，瘙痒停止后有黄赤色液体流出，疼痛难忍。采用灸法、熏蒸、洗涤等方法，使用硫黄、茹草、白僵蚕、羊蹄根等药物，均无效。其父母向戴人求医。戴人说：“若能听从我的建议，病即可痊愈。”父母答应了。戴人将针磨得尖锐锋利，在患者感到瘙痒时，在癣面上各刺百余针，直至出血排尽，再用盐汤清洗。如此进行四次，大病才得以消除。此方不全部告知后人，是担心被癣药所误导，湿气浸淫于血分，不可不用砭石疗法了。

[Dai Ren]: A fifteen-year-old girl suffered from damp tinea between her thighs, extending three to four inches down to her knees. When itching occurred, scratching and hot water application provided no relief; after the itching subsided, yellow-red fluid flowed out, accompanied by unbearable pain. Moxibustion, fumigation, and washing treatments using drugs such as Sulfur (Liuhuang), Rucao, Bombyx Batryticatus (Baijiangcan), and Radix Aconiti Lateralis Preparata (Yangti Gen) were all ineffective. Her parents sought treatment from Dai Ren. Dai Ren said, "If you follow my advice, the disease will be cured." The parents agreed. Dai Ren sharpened needles and, when the patient felt itching, pricked over a hundred times on the tinea area until blood was fully discharged, then washed with saline solution. This was repeated four times, and the major illness was finally eliminated. This method is not fully disclosed to later generations for fear that it might be misled by tinea remedies; when dampness invades the blood, phlebotomy (biān) therapy should not be neglected.
[Moxibustion Method]: At noon, moxa moxibustion (three cones) is applied to the shadow of the diseased area. The incantation states: "Worms in the tinea, hairy and coarse. If you wish to cure, wait for noon."
Another method: On the eighth day of the eighth lunar month at sunrise, have the patient kneel long facing east inside the house, raise both hands flat, hold the sides of the chest, locate the depression between the bones at the tip of the shoulder (Jianjing area), and apply moxibustion. Apply heat to both points simultaneously, three or seven moxa cones each, and recovery occurs within ten days.
