lol, no, the candles are placed on your throat while a short blessing is said. The blessing is against all ailments of the throat (which of course can include choking…)
Here is what happens:
People form a line, as they would for communion.
With the crossed candles touched to the throat of each person, the celebrant says immediately: "Through the intercession of Saint Blase, bishop and martyr, may God deliver you from every disease of the throat and from every other illness: In the name of the Father, and of the Son, + and of the Holy Spirit. "
Or the more modern version of the blessing:
“Through the intercession of St. Blaise, may God preserve you from throat troubles and every other evil, In the name of the Father, Son, + and Holy Spirit”
