St. Pantaleon is regarded as one of the "holy helpers," a powerful intercessor against any sickness.
St. Pantaleon was a 3rd-century physician who treated his patients for free, concerned about both their bodily and spiritual health.
In the Middle Ages he was regarded as one of the miraculous “holy helpers,” a group of saints who were invoked during Europe’s deadliest plagues.
Here is a prayer to St. Pantaleon for good health and protection from any illness.
ST. PANTALEON, who during life didst have great pity for the sick and with the help of
God didst often relieve and cure them; I invoke thy intercession with God, that I may obtain the grace to serve Him in good health by cheerfully fulfilling the duties of my state of life. But if it be His holy will to visit me with illness, pain, and suffering, do thou aid me with thy powerful prayer to submit humbly to His chastisements, to accept sickness in the spirit of penance and to bear it patiently according to His holy will. Amen.
