Help!

(Hello! I'm not really a member here, so I apologize if this breaks any rules or is rude.)

I need help reflecting the energy of a sour jar. For context, two of my friends and a friend of theirs have a person who is planning to make a sour jar. This person is the toxic ex of one of them, and is a very, very cruel person. I need to find a way to reflect the possible sour jar energy. I have looked everywhere and cannot find anything to help. I am not a hoodoo practitioner, but as this is a common hoodoo practice, I wanted to find someone who can help with hoodoo. Thank you so much.

(If this isn't alright to post, or if there's a better place to post it, please let me know!)
