Use with garlic.
"Magical Uses: Use for prophetic dreams, exorcism, and protection. Worn
in a bag around the neck, asafetida dispels diseases and evils of all
kinds. (It literally repels evil spirits!) Add a clove of garlic to
enhance the effect. Asafetida is a classic for exorcism and purification
rites. Use it to smudg a ritual space with smoke. Unfortunately, though
asafetida is powerful, it also has a horrible odor. Just the slightest
whiff of the fragrance has been known to cause vomiting. Use with Care!"
