Hing or heeng is the Hindi word for asafetida (sometimes spelled asafoetida). It's also been known as the devil's dung and stinking gum, as well as asant, food of the gods, jowani badian, hengu, ingu, kayam, and ting. It is a dark brown, resin-like substance that is derived from the root of ferula.

Asafoetida resin is produced by solidifying juice that comes out of cuts made in the plant's living roots. People use asafoetida for conditions such as breathing or throat problems, digestion problems, or by women to restart their menstrual periods after menstruation has stopped for some reason.
