Icon of the Holy Unmercenaries Sts. Kosmas, Damian and Panteleimon (source)
You received from God the grace of healings, and freely heal the passions of our souls and bodies, O universal Unmercenaries. Therefore, through you, Christ grants to His faithful ones good health, showing you to be unerring lights for the whole world. Entreat Him that our souls may be saved.
