Asafoetida powder is a strong concentrated spice used to flavor curries and lentils. Hing is also known to greatly improve digestion.

Asafoetida is an oleogum resin obtained from the living rhizomes and roots of Ferula assa-foetida, a branching perennial relative of fennel. In its most pure form (tears) it is a solid or semi-solid mass, with an intense, pungent, alliaceous odor, and bitter, acid taste. When used in minute quantities it enhances and blends the flavors of other spices, and imparts a delicate, onion-like flavor.
