| "Ferula asafoetida Karst.(Apicaceae) spontaneously grows in many countries of the Middle East. In Iran, the plant exists in two varieties: one bitter, and one sweet. The use of the latter is preferred over the former. Even though Ferula asafoetida grows in more Southerly regions in Iran than Ferula gummosa, there are geographic areas where both species can be found. Its growth characteristics are similar to those of Ferula gummosa, but with a much longer vegetative cycle. The inflorescence forms after 12-14 years, and, as with Ferula gummosa, marks the end of life of the plant. The resin is collected from the upper parts of the root, after incising the totally dry plants. The resinous droplets are collected every 5-6 days, with the root being incised 8-10 times within 2 months. The yield is approximately 40-60 g per season." \\ | "Ferula asafoetida Karst.(Apicaceae) spontaneously grows in many countries of the Middle East.
