The resin-like gum comes from the dried sap extracted from the stem and roots and is used as a spice. The resin is greyish-white when fresh but dries to a dark amber colour. The asafoetida resin is difficult to grate and is traditionally crushed between stones or with a hammer. Today, the most commonly available form is compounded asafoetida, a fine powder containing 30% asafoetida resin, along with rice flour and gum arabic.
