Hoodoo is a set of spiritual practices, traditions, and beliefs created by African slaves in North America that were held in secret from slaveholders. Hoodoo evolved from various traditional African religions and practices, and in the American South, incorporated various elements of indigenous botanical knowledge.
A poppet is, for lack of a better term, a voodoo doll. It is one of the most commonly used implements in sympathetic magick, which entails the idea that “like creates like”. Thus, if you create a poppet of a person, anything to do to that poppet will affect the person it represents. Poppets are especially useful for spells that attract (or keep) a lover, heal, or banish. They can be used anytime you need to affect a specific person.
