In many cultures, serpent mythology is strongly tied to the cycle of life, death and rebirth. Because of these associations, it is a potent ally in magic related to transformation, protection, and other themes.
"In European folk magic snake sheds and other bits can be used for healing and fertility amulets as well as any charms or tools having to do with otherworldly travel. Snakes are sacred to many deities and I like to add powdered snake sheds to incense burned to invoke those deities (Damballah, Hekate, Hermes, Legba, Odin, Veles…)."
In some forms of Hoodoo and folk magic, snakeskin is dried and then ground into a fine powder, sometimes referred to as "snake dust."
Another legend is that if you carry it in your pocket, it will bring you good luck.
