Oftentimes called the female equivalent of the Jigar Khoy, the jigarkhwar of the Sindh region of India is, although similar in many ways, distinctively different type of vampiric witch. The jigarkhwar uses her power of hypnosis to place a person into a trancelike state in order to steal his liver. After the organ has been stolen, the vampiric witch returns to her home and cooks it. While this is occurring, the victim falls suddenly ill. As soon as the last bite of the liver is eaten, the person’s life-energy has been consumed, and he dies. The spell can be reversed as long as a single bite of the liver remains uneaten. As soon as it is eaten, the person’s fate is sealed.
