In Greek mythology, Panacea (Greek Πανάκεια, Panakeia) was a goddess of universal remedy and the daughter of Asclepius and Epione. Panacea and her four sisters each performed a facet of Apollo's art:
Panacea also had four brothers—Podaleirus, one of the two kings of Tricca, who was skilled in diagnostics, and Machaon, the other king of Tricca, who was a master surgeon (these two took part in the Trojan War until Machaon was killed by Penthesilea, queen of the Amazons); Telesphoros, who devoted his life to serving Asclepius; and Aratus, her half-brother, who was a Greek hero and the patron/liberator of Sicyon. However, portrayals of the family were not consistent; Panacea and her sisters each at times appear as Asclepius' wife instead.
Panacea may have been an independent goddess before being absorbed into the Asclepius myth.
Panacea traditionally had a poultice or potion with which she healed the sick. This brought about the concept of the panacea in medicine, a substance meant to cure all diseases. The term is also used figuratively as meaning "Something used to solve all problems".
I swear, calling upon Apollo the physician and Asclepius, Hygeia and Panaceia and all the gods and goddesses as witnesses, that I will fulfill this oath and this contract according to my ability and judgment.

A river in Thrace/Moesia took its name from the goddess, and is still known in modern Bulgaria as the river Zlatna Panega ("Golden Panega", from Greek panakeia).
