【性味】味咸、甘，性平，无毒。
【主治功效】主要治疗小儿一百二十种惊痫（惊风抽搐）、螈疭（手足抽搐）、癫疾（精神失常疾病），寒热往来，肠痔，虫毒，蛇痫（类似癫痫发作），弄舌摇头，大人五邪（泛指各种邪气侵袭所致病症），言语错乱偏颇，恶疮，呕吐咳嗽，明目。用火熬制后使用效果良好。
【别名与产地】又名龙子衣，又名蛇符，又名龙子皮，又名龙子单衣，又名弓皮。产于荆州的山谷及田野间。在五月五日或十五日采集的药材质量最佳。（忌与磁石及酒同用。）
【历代医家论述】陶隐居说：草丛中很少见到虺蛇和蝮蛇，大多见到的长蛇，多是赤练蛇、黄颔蛇之类，它们的皮已经难以辨认，现在往往能获取到完整的蜕皮，都必须要求完整无损。生长在石头上的蜕皮更好，烧成灰后能很好地治疗各种恶疮。
现在参考陈藏器《本草》的说法：蛇蜕，主治疟疾。取发病当天，用蜕下的皮塞住患者的两只耳朵，临发病时又用手拿少许药粉，并服用一合盐醋汁，使其呕吐。
臣禹锡等人谨按《药性论》记载：蛇蜕皮，属臣药，有毒。能主治百鬼魅惑之症，兼治喉痹（咽喉肿痛闭塞）。
日华子说：治疗蛊毒，辟除邪恶之气，止呕逆，治疗小儿惊悸，客忤（外邪侵扰引起的惊恐病症），催生。治疗痈疡、白癜风，煎汁外敷。入药均需炙烤后用。
《图经本草》在蚺蛇胆条目下已有详细文具记录。
雷公说：凡使用蛇蜕，不要用青色、黄色、苍色的，要用白如银色的那种。凡是想要炮制使用，先在屋檐下在地上挖一个坑，深度约一尺二寸，将蛇皮放在坑中，过一夜，到卯时取出，用醋浸泡一个时辰，然后在火上炙烤干燥后使用。
《食疗本草》说：蛇蜕皮，主治去除邪气，明目。治疗小儿一百二十种惊痫，寒热，肠痔，蛊毒，各种恶疮，安胎。需熬制后使用。
《圣惠方》治疗白驳（白癜风）。用烧成的粉末，醋调匀敷患处，效果佳。另一方治疗小儿重舌（舌头肿大重叠）、重断（舌下肿物断裂）肿痛。烧成粉末外敷，有效。
《外台秘要》治疗身体白驳。用熟透的蛇皮摩擦患处，数百遍后，将皮丢弃在草丛中。
《千金方》治疗各种肿胀失治，已有脓液。烧蛇蜕皮，用水调和，封敷在肿胀处，虫子即可出来。另一方治疗紧唇（嘴唇紧缩僵硬）。先用烧成的灰擦拭，再敷上。又一方案用于预产期未到而想提前分娩。取一条全蛇蜕，在腹痛开始时，用绢袋装好，绕在腰间。又一方案：治疗恶疮十年不愈类似癞病的。将整条蛇蜕烧成粉末，用猪脂调和敷上。
《肘后方》治疗小儿初生月蚀疮及恶疮。烧成粉末和猪脂调和，敷上。
《十全博救》救治横生难产方：蛇皮一条，放入瓶中，用盐泥密封固济，存性烧为黑灰。每次服用二钱，用榆白皮汤调服，胎儿即可顺利产出。
《必效方》治疗五痔肛脱。用一枚指头粗的死蛇湿用。挖地作坑烧蛇，取有孔的板覆盖在坑上坐在上面，使虫尽出。
杜壬方治疗缠喉风，咽喉中感觉像被束缚，气不通畅。蛇蜕炙至微黄，与当归等分，研为粉末，温酒调服一钱匕，吐出后痊愈。
姚和众说治疗小儿重舌。焦炙后研末，每天三次敷在舌下，一次敷一粒豆大小的量。
《子母秘录》治疗小儿吐血。烧蛇蜕末，用乳汁调服。又一方案治疗小儿头面身上生各种疮。烧成粉末，和猪脂敷上。
《产书》：治疗产程不顺，手脚先露出的难产情况。蛇蜕皮，烧作灰，研细。面向东用酒送服一钱匕，再用药末敷在手足上，即可顺产。
杨氏《产乳集》治疗婴儿吹奶（乳腺炎），疼痛肿胀欲作急疗方：蛇蜕一尺七寸，烧令变黑，细研，用好酒一盏，微温顿服，若无效可再服。
