"In the United States the annual blessing of throats is a traditional sign of the struggle against illness in the life of the Christian. This blessing is ordinarily given during Mass or a celebration of the word of God on February 3, the memorial of Saint Blaise.
Saint Blaise was the bishop of Sebaste in Armenia during the fourth century. Very little is known about his life. According to various accounts (see endnote 6) he was a physician before becoming a bishop. His cult spread throughout the entire Church in the Middle Ages because he was reputed to have miraculously cured a little boy who nearly died because of a fishbone in his throat. From the eighth century he has been invoked on behalf of the sick, especially those afflicted with illnesses of the throat.
The blessing of throats may be given by a priest, deacon, or a lay minister who follows the rites and prayers designated for a lay minister. If the blessing is conferred during Mass, the blessing follows the homily and general intercessions, or, for pastoral reasons, the prayer of blessing may take the place of the final blessing of the Mass. When the blessing is given outside Mass, it is preceded by a brief celebration of the word of God. If the blessing is to be celebrated at Morning Prayer or Evening Prayer, it is given after the reading and responsory (and homily) and before the gospel canticle.
The blessing may be given by touching the throat of each person with two candles blessed on the feast of the Presentation of the Lord (February 2) and which have been joined together in the form of a cross."
