This pungent material is the dried oleoresin from the taproot of the herb known as Ferula. Popular names for this substance include Devil's Dung, Hing, Ting, or stinky gum, due to its unpleasant aroma. This perennial herb grows to six feet in height, with bright yellow flowers. The often unpleasant aroma of oleoresin is offset by its value as a culinary spice. Asafoetida has a strong distinctive flavor described as reminiscent of onions or leeks. The spice is very popular in Asia for the flavor it imparts and for its anti-flatulent and anti-microbial properties.
