Asafoetida, or asafetida (Ferula assafoetida), is a plant native to Iran that has a strong sulfurous smell. The sap of the stem and roots is dried and crushed to form an onion-tasting powder that is frequently used in Indian and Middle Eastern cuisine. Jains (followers of the Jain religion, an ancient faith based on the teachings of the prince Mahavira, 599 - 527 BC) also use it as a substitute for onions.
There is currently little information available on the pharmacology and medicinal uses of asafoetida. Limited animal research suggests that asafetida may increase the calcium and zinc content in bone after exposure to radiation. However, there is currently insufficient evidence in humans to support the use of asafoetida for any indication.
