Ferula assa-foetida

The production of asafoetida from this species is confined to Southern Iran, especially the area near Lar.

[2][3][4] Outside its native range, other asafoetida-producing species are often misidentified as F.

[6][7] In a molecular phylogenetic study, all the plant samples of F. assa-foetida collected in Central Iran were not the true species, but F. alliacea and F. gabrielii or their close relatives instead.

[8] Chemical analyses of asafoetida samples obtained from local markets in Eastern Iran also showed that asafoetida-producing species there were F. lutensis, F. foetida, F. alliacea, etc., instead of F.

[2][3] F. pseudalliacea and F. rubricaulis are endemic to western and southwestern Iran and are sometimes considered conspecific with F.
