This peculiar powder is used by a woman (but it could also be used by men) who wants her partner to be faithful, to the point were it makes him detested by all the other women. Infidelity is certainly one of the worst vices , it causes suffering and anguish for the person who loves and feels betrayed or is worried that he/she may be. This powder has been specially created to fight this problem. In the Voodoo magic this compound takes the name of Black Devil. According to the tradition this powder makes the loved one detested by all the other people who could involve him in an affair. It has to be clear that the influence of this wise powder does not ruin one's reputation, nor does it bring contempt, but it only works for fidelity. If the partner is unfaithful or visits environments where it is easy to be unfaithful, he will appear unpleasent to the eyes of the possible lovers. The effect is so immediate, that works even if the affair is already in action, inverting the passion into disgust and by forcing the loved one to go back home.
