Snakeskin and snakes are used in love and passion spells to promote sexual potency. A skin shed by a snake carries potent magic energies as it represents transformation, spells transform too.
Buy a snakeskin unless you are able to find one.
Sprinkle it with Lunar Water.
Light a red candle and state:
Snake spirit that shed its skin,
burn passion within,
my lover’s heart,
for me,
so mote it be.
