Vampire
Folk beliefs
Apotropaics—items able to ward off revenants—are common in vampire folklore. Garlic is a common example, a branch of wild rose and hawthorn are said to harm vampires, and in Europe, sprinkling mustard seeds on the roof of a house was said to keep them away. Other apotropaics include sacred items, for example a crucifix, rosary, or holy water. Vampires are said to be unable to walk on consecrated ground, such as that of churches or temples, or cross running water.
