A bokor or boko is a Voudoo or Voudoun houngan or magician who performs spiritual work for clients in return for gifts or money, as opposed to just honoring the Loa.

What separates them from other Voodoo practitioners is that, in general, they “serve with both hands”: performing many rituals involving black magic or to bring harm to others, that most other initiated Voodoo Houngan and Mambo will not.
