This practice is dates back to many years ago, using herbs like sage, Palo Santos, sweet bush, lemon grass, frankincense, you name it. But from what I've heard, Palos Santos is stronger and more effective, second is the Sage as pictured above. I used it to cleanse my space especially after I've done a big clean. I experience psychic attacks and have come in contact with bad energy and witchery thrown my way by malicious people, which led to me gaining knowledge about these things. So are you familiar with these practices? and please before you make these assumptions, this is not black magic or anything against God, as a matter of fact these are Godly practices.
