OVERVIEW
Asafoetida is a plant. It has a bad smell and tastes bitter. That probably explains why it is sometimes called “devil's dung.”
People use asafoetida resin, a gum-like material, as medicine. Asafoetida resin is produced by solidifying juice that comes out of cuts made in the plant's living roots.
Asafoetida is used for breathing problems including ongoing (chronic) bronchitis, H1N1 "swine" flu, and asthma. It is also used for digestion problems including intestinal gas, upset stomach, irritable bowel syndrome (IBS), and irritable colon. Other uses include treatment of “whooping cough” (pertussis), croup, and hoarse throat.
Some people use asafoetida for hysteria, insanity, convulsions, and as a nerve stimulant for ongoing mental and physical fatigue with depression (neurasthenia).
Women sometimes use asafoetida to restart their menstrual periods after menstruation has stopped for some reason.
Asafoetida is sometimes applied directly to the skin for corns and calluses.
In manufacturing, asafoetida is used as a fragrance in cosmetics and as a flavoring ingredient in foods and beverages. Asafoetida is also used in products meant to repel dogs, cats, and wildlife.
How does it work?
There is some scientific evidence that the chemicals in asafoetida might help treat irritable bowel syndrome (IBS), and also might protect against high blood levels of certain fats including cholesterol and triglycerides. Chemicals called coumarins in asafoetida can thin the blood.
