Hoodoo

'Somebody came against a very popular preacher. "He's getting too rich and big. I want something done to keep him down. They tell me he's 'bout to get to be a bishop. I sho' should hate for that to happen. I got forty dollars in my pocket right now for the work."
So that night the altar blazed with the blue light. We wrote the preacher's name on a slip of paper with black ink. We took a small doll and ripped open its back and put in the paper with the name along with some bitter aloes and cayenne pepper and sewed the rip up again with the black thread. The hands of the doll were tied behind it and a black veil tied over the face and knotted behind it so that the man it represented would be blind and always do things to keep himself from progressing. The doll was then placed in a kneeling position in a dark corner where it would not be disturbed. He would be frustrated as long as the doll was not disturbed.'
Zora Neale Hurston Mules and Men (1935)

A braver man would tell you about the Black Cat Bone as well.
