Well depending on who you ask, poo (and anything else) CAN in fact be esoteric. Anything focused on by someone intending to practice magic of any form can become imbued with esoteric/magical energy to that person.
Herbs are interesting in this respect as they are capable of both acquiring this magical energy AND affecting their users through the senses (smell, taste, ingestion, etc.)
This being said, I believe that you should start the mysterious new school of poo magic.
