Asafetida

Asafetida, also known as gum asafetida, devil's dung, or blood of the gods, was a type of gum resin extracted from certain plants' taproots and rhizomes and that was dried and used as a spice or condiment.

Usages
Asafetida was one of the ingredients in the special enchanted ink used to scribe scrolls of shocking grasp. Asafetida, balm of gilead, ginseng, and mace (or masterwort), were burnt into ash, mixed with ash of a tree incinerated by lightning, and mixed with the rest of ingredients.

Asafetida was believed to have some minor medicinal uses. Some considered tonics brewed with the substance to be beneficial for one's brain and nervous systems, possessing stimulating qualities, and even an aphrodisiac.
