Aswang - Female Vampire Name

A witch-woman who appeared as a beautiful maiden when she rubbed herself with a certain ointment. She would fly, at night, to the roof of a house and send down her long tongue to prick the throat of her sleeping victim, then she would drink the blood.

When fully fed she appeared as a pregnant woman. (Philippines)
