Repel Evil and black magick

What kind of witch would I be if I did not offer this?  

We have at one time or another, been attacked or known someone that has. This is designed to repel it, if it's already there, a cleansing is probably needed but this will repel the attack as it gets going and send it back to the sender 10 fold. 

This comes with the powder, a candle, and a spirit (Optional and costs a little more) to help do just that.
