Asafoetida

Asafoetida is the dried latex exuded from the rhizome or tap root of several species of Ferula, perennial herbs growing 1 to 1.5 m tall. They are part of the celery family, Umbelliferae. Asafoetida is thought to be in the same genus as silphium, a North African plant now believed to be extinct, and was used as a cheaper substitute for that historically important herb from classical antiquity. The species are native to the deserts of Iran and mountains of Afghanistan where substantial amounts are grown.
