James George Frazer,
The Golden Bough
(1922)
“ Spittle tabooed.—The same fear of witchcraft which has led so many people to hide or destroy their loose hair and nails has induced other or the same people to treat their spittle in a like fashion. For on the principles of sympathetic magic the spittle is part of the man, and whatever is done to it will have a corresponding effect on him. A Chilote Indian, who has gathered up the spittle of an enemy, will put it in a potato, and hang the potato in the smoke, uttering certain spells as he does so in the belief that his foe will waste away as the potato dries in the smoke. ”
