Nicarete was a 5th-century saint from Nicomedia who became a follower of John Chrysostom. Seeking to deepen her theological knowledge and serve those in need, she relocated to Constantinople. There, she combined her religious devotion with her skills as a healer and herbalist. She is particularly noted for her medical assistance to Chrysostom, whom she helped during an illness, and her loyalty to him when he was later forced into exile.
