Asafoetida's English and scientific name is derived from the Persian word for resin (asa) and Latin foetida, which refers to its strong sulfurous odour. Typical asafoetida contains about 40-64% resin, 25% endogeneous gum, 10-17% volatile oil, and 1.5-10% ash. In respect of compounded asafoetida in powder form, the dark brown semi solid mass is allowed to dry in the sun.
