A traditional reversal work in Latin America is the Revocación con San Miguel Arcangel. It purpose is to call off any work sent against you and turn it back against to who threw it. One of the good things about this trick is that it doesn't call on any names so it sends back any harm known or unknown to you. There are two variations to this work and the prayer.
1 Red Candle
1 white plate
First you say a prayer to st Michael, any of your choice, prayer from the heart also works. Then you take the red candle, cut the top off and carve out a new wick out of the bottom. Holding the candle in its former upright position and pray the following as you turn it:
As i turn this candle i have on my hand so may all my enemies and all wrong they are doing against me or trowing against me turn, be it man or woman. May I call on my enemies with these holy words and have them come humiliated to my feet, as Satan was humiliated to saint Michael's feet. may they have eyes and not see me, hand and not touch me, thoughts and not think of me, knives and not cut me, weapons and not shoot me, mouth and not speak to me. May all harm found at my home be undone and return, so it may become a blessing, and may anyone trying to do harm against me have his ideas undone and turn back in regret. In the name of the Father, the Son and the Holy Spirit, in the name of all that is good, Amen.
The second version of the trick calls for a glass which you fill up with water to a little bit more than half, place a plate on top of it and turn it around, setting a white candle on top of the glass which you have fixed the same way as the red candle. After the candle burns out you dispose of the water and cleanse the glass with a bit of ammoniac.
If you wish to add reversal oil to the candle or Saint Michael oil it can be done without any problem.
