What does St. Benedict’s medal mean?

From Catholic Link

The Saint Benedict Medal can be blessed by any priest not necessarily a Benedictine.

The following prayers are to be said:

“

V: Our help is in the name of the Lord. R: Who made heaven and earth. V: In the name of God the Father + almighty, who made heaven and earth, the seas and all that is in them, I exorcise these medals against the power and attacks of the evil one. May all who use these medals devoutly be blessed with health of soul and body. In the name of the Father + almighty, of the Son + Jesus Christ our Lord, and of the Holy + Spirit the Paraclete, and in the love of the same Lord Jesus Christ who will come on the last day to judge the living and the dead, and the world by fire. R: Amen. V: Let us pray. Almighty God, the boundless source of all good things, we humbly ask that, through the intercession of Saint Benedict, you pour out your blessings + upon these medals. May those who use them devoutly and earnestly strive to perform good works be blessed by you with health of soul and body, the grace of a holy life, and remission of the temporal punishment due to sin. May they also with the help of your merciful love, resist the temptation of the evil one and strive to exercise true charity and justice toward all, so that one day they may appear sinless and holy in your sight. This we ask through Christ our Lord. R: Amen.

”

The medal is then sprinkled with holy water.

It is effective in many ways:

• to destroy witchcraft and all other diabolical and haunting influences;

• to impart protection to persons tempted, deluded, or tormented by evil spirits;

• to obtain the conversion of sinners to the Catholic Church, especially when they are in danger of death;

• to serve as an armor against temptation;

• to destroy the effects of poison;

• to secure a timely and healthy birth for children;

• to afford protection against storms and lightning;

• to serve as an efficacious remedy for bodily afflictions and a means of protection against contagious diseases.
