Saint Anastasia Stritzoula is a Christian saint and martyr who died at Sirmium in the Roman province of Pannonia Secunda. In the Orthodox Church, she is venerated as St. Anastasia the Pharmakolytria, i.e. "Deliverer from Potions".
Concerning Anastasia, little is reliably known, save that she died in the persecutions of Diocletian; most stories about her date from several centuries after her death and make her variously a Roman or Sirmian native and a Roman citizen of patrician rank. One legend makes her the daughter of a certain Praetextatus and the pupil of Saint Chrysogonus. Catholic tradition states that her mother was St. Fausta of Sirmium.
Anastasia has long been venerated as a healer and exorcist. Her relics lie in the Cathedral of St. Anastasia in Zadar, Croatia.
She is one of seven women who, along with the Blessed Virgin Mary, are commemorated by name in the Roman Canon of the Mass.
